It is not clear whether turmeric, of which curcumin is a major constituent, would have similar effects, but if large doses are given an effect seems possible. It would seem prudent to warn patients taking curcumin, and turmeric, about the possible increase in sedative effects. T No interactions have been included for herbal medicines or dietary supplements beginning with the letter U U 393 Valerian Valeriana officinalis L. In vitro investigations have suggested that valerian may inhibit P-glycoprotein,1,5 although the authors of one study concluded that this is unlikely to be clinically relevant, because the concentration at which this occurred is unlikely to be attained in vivo,5 and the findings of another study suggested that the effects were much weaker than those of verapamil, a known, clinically relevant P-glycoprotein inhibitor. Constituents Valerian root and rhizome contains a large number of constituents which vary considerably according to the source of the plant material and the method of processing and storage. Many are known to contribute to the activity, and even those that are known to be unstable may produce active decomposition products. The valepotriates include the valtrates, which are active constituents, but decompose on storage to form other actives including baldrinal, and volatile constituents. The volatile oil is composed of valerenic acids and their esters, and other derivatives including isovaleric acid (which is responsible for the odour of valerian), and others. Valerian dry hydroalcoholic extract is an extract produced from valerian root and contains a minimum of 0. It has long been used as a hypnotic, sedative, anxiolytic, antispasmodic, carminative and antihypertensive, and for hypochondriasis, migraine, cramp, intestinal colic, rheumatic pains and dysmenorrhoea. A recent study suggested that it is safe, but not necessarily effective; however, many analytical reports also show that extracts and products of valerian vary greatly in both chemical composition and biological activity, and it may be that only certain preparations have any therapeutic benefit. Many commercial products use valerian in combin- Interactions overview Valerian does not appear to affect the metabolism of alprazolam, caffeine, chlorzoxazone, dextromethorphan or midazolam to a clinically relevant extent. Valerian may increase the sleeping time in mice in response to alcohol and barbiturates. For information on the interactions of individual flavonoids present in valerian, see under flavonoids, page 186. In vitro activity of commercial valerian root extracts against human cytochrome P450 3A4. In vivo effects of goldenseal, kava kava, black cohosh, and valerian on human cytochrome P450 1A2, 2D6, 2E1, and 3A4/5 phenotypes. Other barbiturates do not appear to have been studied, but it seems likely that they will interact similarly. It may therefore be prudent to consider the potential additive sedative effects in any patient taking barbiturates with valerian. This seems most likely to be of importance with the use of phenobarbital (or other barbiturates) for epilepsy, when sedative effects are less desirable. It would be prudent to warn patients that they may be more sedated and, if this occurs, to avoid undertaking skilled tasks. Valerian + Alcohol the interaction between valerian and alcohol is based on experimental evidence only. Experimental evidence In a study in mice, a valepotriate extract of valerian, given in high doses, almost doubled the sleeping time in response to alcohol. In contrast, in a separate experiment, the extract appeared to antagonise the effects of alcohol on motor activity. Importance and management the evidence of an interaction between valerian and alcohol appears to be limited to a study in mice. However, valerian is said to have sedative effects, and is used for insomnia, and so additive effects on sedation seem possible. It would be prudent to warn patients that they may be more sedated if they drink alcohol while taking valerian and, if this occurs, to avoid undertaking skilled tasks. Note that, in the study in mice, the sedative effects of valepotriates, even in large doses, were more modest than those of diazepam and chlordiazepoxide. Valerian + Benzodiazepines Valerian does not affect the pharmacokinetics of alprazolam or midazolam to a clinically relevant extent. Clinical evidence In a crossover study, 12 healthy subjects were given valerian root extract 1 g each night for 14 days, with a single 2-mg dose of alprazolam on the morning of day 15.

We also considered studies submitted during the public comment process for possible inclusion. We performed dual full-text review for any study not excluded by review of title and abstract (Appendix J lists the excluded studies at full-text review, with reasons). For studies on which we did not agree after initial full-text review, we discussed each study and came to consensus. We also screened included references from the prior report16 against our inclusion/exclusion criteria for this report. Each trial was assessed using Center instruments adapted from national and international standards and assessments for risk of bias. The methodological quality of clinical practice guidelines was rated as good, fair, or poor. The assessment criteria for the methodological quality of the clinical practice guidelines are shown in Appendix B. Data Analysis and Synthesis We combined data in meta-analyses for the key outcomes of response. We did not identify any new eligible trials so were not able to update the analyses with new data. In the worst-case analysis, we assumed that participants not completing follow-up or with inadequate seizure data were nonresponders in the intervention group, and were responders in the comparison group. Specific measures from general domains of interest were selected in a post-hoc manner based on the outcomes available from the included studies. The true effect is likely to be close to the estimate of the effect, but there is a possibility that it is different. Low: Raters have little confidence in the estimate of the effect of the intervention on the outcome. Very low: Raters have no confidence in the estimate of the effect of the intervention on the outcome. The true effect is likely to be substantially different from the estimate of the effect. Evidence Summary Our searches returned a total of 1,168 records, published since 2009 (the search date in the prior report16). We also checked the reference lists of relevant systematic reviews10,17-48 and added a further 7 studies for review. We also screened 71 references included in the prior report16 against the inclusion/exclusion criteria for this report. At the end of the 19-week add-on phase, children experienced a significant improvement in depression (P =. In the high- and low-stimulation groups, patient, interviewer, and companion ratings of patient wellbeing were higher at the end of treatment than at baseline (P <. However, when the proportions of children who reported worsened, unchanged, or improved quality of life were compared, there were no significant differences between the groups (P >. Children also experienced behavioral changes, including agitation, crying, and frequent startles. Other adverse events, such as cardiac or respiratory complications and local infections, were low at all-time points (0. Patients in the high- and low-stimulation groups experienced a numerical reduction in depression severity at week 22, but there was no significant difference between the groups (P >. No patients died by suicide in the medium-stimulation group and the rates of attempted suicide were similar between the medium- and low-stimulation groups. Response rates were also not significantly different between the medium-stimulation and low-stimulation groups. In the first and second year post-identification period, 2,979 of 6,005 (50%) in the managed depression group had no negative events and 219 (4%) had negative events. We were not able to analyze the reports by condition, but the types of adverse events appeared similar to those reported in our eligible studies for epilepsy and depression.

This study also suggests that danshen is unlikely to affect the metabolism of other drugs that are substrates of this isoenzyme. Induction of cytochrome P450dependent monooxygenase by extracts of the medicinal herb Salvia miltiorrhiza. D Danshen + Warfarin and related drugs Three case reports and some animal data indicate that danshen can increase the effects of warfarin, resulting in bleeding. The anaemia was attributed to occult gastrointestinal bleeding and the over-anticoagulation to an interaction with the danshen. Other iridoid glycosides include harpagide and procumbide, and other constituents include diterpenes, the phenolic glycosides 6-acetylacteoside and 2,6-diacetylacteoside, flavonoids (including kaempferol), triterpenes and harpagoquinone. Simultaneous determination of the inhibitory potency of herbal extracts on the activity of six major cytochrome P450 enzymes using liquid chromatography/mass spectrometry and automated online extraction. Use and indications the dried secondary root tuber is used as a stomachic and bitter tonic, and for inflammatory disorders including arthritis, gout, myalgia, fibrositis, lumbago and rheumatic disease. One patient had an episode of tachycardia while on holiday, and stopped taking the herbal medicine. It was suggested that this adverse event was due to the change in climate rather than the medication. Importance and management Clinical evidence is limited to one study that was not specifically designed to assess interactions. The reduction in blood pressure found in animal studies seems unlikely to be clinically relevant, due to the high doses used. Circosta C, Occhiuto F, Ragusa S, Trovato A, Tumino G, Briguglio F, de-Pasquale A. Importance and management Evidence is limited to a case study, which reports minor adverse effects, and experimental data. The evidence is too sparse to make any firm recommendations, but it may be prudent to consider a possible interaction if a patient taking a coumarin develops otherwise unexplained bruising. Simultaneous determination of the inhibitory potency of herbal extracts on the activity of six major cytochrome P450 enzymes using liquid chromatography/mass spectrometry and automated online extraction. The pressed juice (from the aerial parts) contains heterogeneous polysaccharides, inulin-type compounds, arabinogalactan polysaccharides and glycoproteins. Use and indications Echinacea is mainly used for its immunostimulant (immunomodulatory) effects, particularly in the treatment and prevention of the common cold, influenza and other upper respiratory tract infections. It has a long history of medicinal use for infections, both bacterial and viral, especially in skin conditions such as acne and boils, and also in mild septicaemia. E Pharmacokinetics Most work has been carried out using Echinacea purpurea, although other Echinacea species have been studied on selected isoenzymes. Constituents the constituents of the various species are slightly different and this leads to confusion as to the potential for drug interactions. Alkylketones, and the saturated pyrrolizidine alkaloids, tussilagine and isotussilagine, are also present (these are not the unsaturated hepatotoxic type). Polyenes and polyacetylenes, including a range of ketoalkenes and ketopolyacetylenes, have been reported and polysaccharides and glycoproteins are also present. The herb contains similar alkamides, and cichoric acid is the major caffeic acid derivative present. Analysis of the inhibitory potential of Ginkgo biloba, Echinacea purpurea, and Serenoa repens on the metabolic activity of cytochrome P450 3A4, 2D6, and 2C9. Cytochrome P450 inhibitory action of Echinacea preparations differs widely and co-varies with alkylamide content. An in vitro evaluation of human cytochrome P450 3A4 inhibition by selected commercial herbal extracts and tinctures. Interactions overview Theoretically, echinacea may antagonise the effects of immunosuppressants. The use of echinacea has been studied with a number of drugs that are used as probe substrates for cytochrome P450 activity or P-glycoprotein. With the possible exceptions of midazolam and caffeine, no clinically relevant interactions have been identified. Echinacea seems to present a low risk for interactions occurring as a result of these mechanisms.

An interesting aspect of estrogen as a neurosteroid has recently been discovered, and tempers the outlook of estrogen as a proconvulsant molecule, which were initially appreciated in the studies described above. Specifically, estrogen dose, route of administration, acute versus chronic administration, natural hormonal milieu, and estrogenic species can alter whether estrogen is proconvulsant or anticonvulsant. The route of administration of even physiologic doses estrogen also influences its modulating effects on neuroexcitability. This differential effect may be due to opposing genomic versus nongenomic neurophysiologic actions related to the time course associated with the route of administration. For example, intermittent estrogen injections have an anticonvulsant effect in a kainic-acid model compared to constant release from an estrogen implant which had no effect on seizure onset, for example (25,27). A clear example of the differentiation in effects of estrogenic species was demonstrated early in this exploration; focal application of -estradiol on the cerebral cortex had no epileptogenic effects, in contrast to the application of conjugated equine estrogens, predominantly comprising estrone, which produced an epileptogenic focus, suggesting that the mixture of conjugated equine estrogens and estrone has higher proepileptogenic potency compared to -estradiol (8). Therefore these experiments indicate that the proconvulsant and anticonvulsant effects of estrogen on seizures are linked to its complex activity in the brain, and further, the examples cited herein have ready extrapolation to the use of estrogen in humans. Progesterone In contrast, progesterone has long been known to have a seizure-protective effect, as demonstrated in early studies. High doses induce sedation and anesthesia in rats and in humans (28), primarily as a result of actions of the metabolite pregnanolone. Progesterone reduces spontaneous interictal spikes produced by cortical application of penicillin (29), and suppresses kindling (30) and focal seizures (31) in animals. It also heightens the seizure threshold to chemical convulsants (32,33), elevates the electroshock seizure threshold (7,34), and attenuates ethanol-withdrawal convulsions (32). Allopregnanolone is formed from progesterone by two sequential A-ring reductions catalyzed by 5 -reductase and 3 -hydroxysteroid oxidoreductase isoenzymes. Allopregnanolone is a potent, broad-spectrum anticonvulsant agent which is the active anticonvulsant progestin molecule in the diverse animal seizure models (35,41) as described above. The major isoforms consist of two -subunits, two -subunits, and one 2-subunit, and are primarily localized to synapses (45). This increases the chloride current through the channel, hyperpolarizing the cell and resulting in reduced cellular excitability. This dynamic quality has implications for seizure threshold during menstrual cycling, although the alterations in receptor composition are not completely understood. Complicating progesterone picture, both progesterone and allopregnanolone exacerbate seizures in animal models of absence epilepsy (49,50). Testosterone the neurophysiologic activity of testosterone is no less complex than the previously discussed reproductive hormones. Androgens are irreversibly converted in the body to two major classes of biologically active metabolites: estrogens, formed through the action of a cytochrome P450 enzyme, aromatase; and the 5 -reduced androgens, formed via reduction of the steroid "A" ring catalyzed by 5 -reductase. Aromatase and 5 -reductase are expressed in a large number of organ systems, including the brain (51). More recently, two other endogenous testosterone metabolites present in fairly high concentrations in men, androsterone and etiocholanolone, have also been found to have anticonvulsant neurosteroid properties (56). Consistent with the concept that the androgenic metabolic pathway toward estrogen is proconvulsant, in one recent report evaluating the effect of testosterone on pentylenetetrazoleinduced seizures in rats, pretreatment with high doses of the aromatase inhibitor letrozole (which blocks the conversion of testosterone to estrogen) markedly increased the seizure threshold compared to the effect of testosterone alone (57). Anatomic specificity and changes with maturation in the cortical distribution of steroid hormone receptors may account for some of the differential effects of each steroid hormone on neuronal excitability, endocrine function, and reproductive behavior. Neocortical receptors for estrogen in the immature brain are largely absent after puberty (3,66). Anatomic specificity and varying distribution might account, in part, for changes in seizure expression with changes in reproductive function.

Lamotrigine 300 mg day-1 has been found to cause only a modest reduction (19%) in levonorgestrel levels [13]. In comparison, the reduction in ethinylestradiol and progestagen levels with carbamazepine 600 mg day-1 is in the order of 50% [12, 71, 73]. Gabapentin, levetiracetam, pregabalin, tiagabine, valproate, vigabatrin and zonisa- rarely. By virtue of its enzyme-inhibiting properties, valproic acid may increase the plasma levels of a variety of drugs, including zidovudine, lorazepam, nimodipine, paroxetine, amitryptiline, nortriptyline, nitrosureas and etoposide [2]. At least for amitriptyline and nortriptyline [66, 67], and for some antineoplastic drugs [52], these interactions may cause signs of toxicity. Pharmacodynamic interactions enzyme induction and upregulation of acetylcholine receptors. Whenever possible, these interactions should be prevented by avoiding the unnecessary use of polytherapy, and by selecting comedications which are less likely to interact. If the use of potentially interacting drugs cannot be avoided, adverse clinical consequences may be minimized, as appropriate, by individualized dose adjustments guided by careful monitoring of clinical response and measurement of serum drug concentrations. These drugs, however, have a narrow therapeutic window, and interactions affecting their pharmacokinetics or pharmacodynamics may result in serious complications [76]. Under these circumstances, the metabolism of the antocoagulant will slow and, if dosage is not reduced, there is a serious risk of massive haemorrhage [79]. As a result of this, achieving a stable level of anticoagulation may be difficult when warfarin and phenytoin are combined [80]. Valproic acid may also increase serum warfarin concentrations, and facilitate bleeding by interfering directly with platelet function and coagulation processes [81]. Levetiracetam 2000 mg day-1 and tiagabine 12 mg day-1 have also been reported not to interfere with the anticoagulant effect or the pharmacokinetics of warfarin [2].

These shared features suggest that infectious and immunization-related febrile seizures are expressions of a unitary condition. Associated Factors Ancillary factors related to underlying illness or fever may be implicated in the pathogenesis of febrile convulsions, usually with little supportive evidence. Direct viral invasion of brain tissue has been proposed (39), but children with proven viral infections appear no more likely to experience seizure recurrence than do uninfected children (40). Electrolyte disturbances are said to lower seizure threshold, but this mechanism remains relatively unsupported (41). Transient pyridoxine deficiency seems unlikely, and the association of Shigella infection and febrile seizures has prompted a search for an epileptogenic neurotoxin. Proinflammatory cytokines have recently been implicated in the pathogenesis of febrile seizures. Girls younger than 18 months of age have a slightly higher risk than boys of experiencing more frequent and severe febrile seizures (44,45). Ounsted (46) proposed that an excess of boys from one-sex sibships may explain the male predominance that has been observed in some studies (46,47) but not in others (26). Fever Febrile seizures typically occur relatively early in an infectious illness, usually during the rising phase of the temperature curve. The contribution of the rate of rise versus the final temperature reached in inducing the seizure has been debated (30). However, despite the implicit relationship between fever and seizure activation, temperature itself probably does not lower the seizure threshold. The incidence of febrile seizures does not increase in proportion to temperature elevation, and febrile seizures are generally uncommon in the later stages of a persistent illness. A brief duration of fever before the initial febrile seizure has been linked to an increased risk for seizure recurrence (32). Febrile seizures typically are associated with common childhood illnesses, most frequently viral upper respiratory tract, middle ear, and gastrointestinal infections. They occur in neurologically normal children and are not associated with persistent deficits. Despite their common occurrence, the sporadic nature and brief duration of febrile seizures make analysis difficult. Descriptions provided by parents and emergency department personnel are retrospective and probably not entirely accurate. Video-electroencephalographic studies of afebrile generalized seizures, for example, often reveal subtle atonic or myoclonic components that were omitted in the witnessed accounts. Electroencephalography has not been particularly useful in the evaluation of simple febrile seizures. Slow-wave activity occurs in up to one third of patients (51), and is often bilateral and prominent in the posterior regions (47). None were specific for febrile seizures because all had been described in generalized epilepsies as well. The diagnostic yield of such studies is usually well below 2%, however, and difficult to justify (53). The confirmation of viral meningitis by lumbar puncture does not alter long-term management. The evaluation of simple febrile seizures should therefore rely primarily on careful history taking, and judicious laboratory and radiologic testing. This approach, which is particularly important in children who are normal, has been underscored in an editorial (55) stating that "children who have their first febrile convulsion need no more tests than the clinical findings dictate. Testing can usually be performed in an outpatient setting because risk of seizure recurrence is low. In 1975, 24% of practicing pediatricians routinely admitted children after a first febrile seizure; a decade later, 20% still followed this practice (56). However, a more recent evaluation (57) found a decline in the rate of admission with the decision to admit most frequently occurring in those with prolonged seizures. Complex Febrile Seizures the concept of a "complex" febrile seizure originated with epidemiologic studies indicating that several patient- and seizure-related variables predicted higher rates of subsequent epilepsy: seizure duration longer than 15 minutes, focal seizure manifestations, seizure recurrence within 24 hours, abnormal neurologic status, and afebrile seizures in a parent or sibling (58).

The combination of chlomipramine with valproic acid may result in elevation of chlomipramine levels with associated seizures (100). When combined with other serotonergic agents or monoamine oxidase inhibitors, however, they may induce the "serotonin syndrome" of delirium, tremors, and, occasionally, seizures (103). Other symptoms include agitation, myoclonus, hyperreflexia, diaphoresis, shivering, tremor, diarrhea, incoordination, and fever. Venlafaxine, a serotonin and norepinephrine reuptake inhibitor, has emerged as a common cause of drug-induced seizures (104). Both the phenothiazines and haloperidol have been implicated, but the potential is greater with phenothiazines, and seizures occur more frequently with increasing dosage (108). Clozapine, an atypical antipsychotic agent (dibenzodiazepine class) used for the treatment of intractable schizophrenia, may also be useful for tremor and psychosis in patients with Parkinson disease (109,110). As with other antipsychotic agents, the incidence of seizures increases with increasing dosage (111). If reduction of dosage is not practical, phenytoin or valproate may be added; however, carbamazepine should be avoided because antipsychotic agents may induce agranulocytosis. Massive overdosage may induce hypocalcemia and other electrolyte abnormalities (113). Lidocaine precipitates seizures, usually in the setting of congestive heart failure, shock, or hepatic insufficiency. General anesthetics, such as ketamine and enflurane, are also implicated (see "Central Anticholinergic Syndrome"). Alfentanil is a potent short-acting opioid agent that may induce clinical and electroencephalographic seizures (114). Verapamil intoxication may be associated with seizures through the mechanism of hypocalcemia, although hypoxia also may play a role (115). Other calcium-channel blockers have not been reported to produce this adverse effect. Meperidine, pentazocine, and propoxyphene, among other analgesic drugs, infrequently cause seizures (116). Many antiparasitic agents and antimicrobials, particularly penicillins and cephalosporins in high concentrations, are known seizure precipitants. It should be noted that some antibiotics, such as the fluoroquinolones, may lower the seizure threshold. Carbapenem antimicrobials also have significant neurotoxic potential, with meropenem perhaps having the lowest incidence (117,118). Lindane, an antiparasitic shampoo active against head lice (Pediculosis capitis), has a rare association with generalized, self-limited seizures; it is best to use another agent should reinfestation occur. Severe isoniazid intoxication involves coma, severe, intractable seizures, and metabolic acidosis. Conventional doses of short-acting barbiturates, phenytoin, or diazepam are also recommended to potentiate the effect of pyridoxine (120). Recreational Drug-Induced Seizures Alldredge and associates (121) retrospectively identified 49 cases of recreational drug-induced seizures in 47 patients seen between 1975 and 1987. The recreational drugs implicated were cocaine (32 cases), amphetamines, heroin, and phencyclidine; a combination of drugs was responsible for 11 cases. Seizures occurred independently of the route of administration and were reported in both first-time and chronic abusers. Except for one patient who experienced prolonged status epilepticus causing a fixed neurologic deficit, most patients had no obvious short-term neurologic sequelae (121). Patients with seizures who test positive for marijuana on toxicologic screening should be investigated for other illicit drug and alcohol use. Cocaine, a biologic compound that is one of the most abused recreational drugs in the United States, commonly gives rise to tremors and generalized seizures. Seizures can develop immediately following drug administration, without other toxic signs. Pascual-Leone and coworkers (123) retrospectively studied 474 patients with medical complications related to acute cocaine intoxication. Of 403 patients who had no seizure history, approximately 10% had seizures within 90 minutes of cocaine use.

They are probably common in the general population, with an estimated prevalence of 2 to 33 per 100,000, making this problem nearly as common as multiple sclerosis or trigeminal neuralgia. Thus, however uncomfortable they may be, neurologists and epileptologists will have to deal with this issue. This chapter will first review the steps involved in making the diagnosis, and will then turn to management considerations. Strictly speaking, terms like pseudoseizures, nonepileptic seizures, and nonepileptic events include both psychogenic and nonpsychogenic. Examples of nonpsychogenic episodes include syncope (the most common), paroxysmal movement disorders. On the other hand, terms like psychogenic or hysterical seizures refer to a subset of nonepileptic seizures that adds the very important connotation of a psychological origin. A number of "red flags" are useful in clinical practice, and should raise the suspicion that "seizures" may be psychogenic rather than epileptic. This is because the diagnosis of epilepsy is usually based solely on the history and may be difficult. If the historian and witnesses are astute enough, the detailed description of the spells often includes characteristics that are inconsistent with epileptic seizures. A very consistent finding is that about a quarter of patients previously diagnosed with epilepsy and who are not responding to drugs are found to be misdiagnosed. This is true in both in referral epilepsy clinics and in epilepsy monitoring units (2,4,5). Postictal stertorous breathing is quite specific for convulsive epileptic seizures (29,30), as is postictal nose rubbing (31). Obviously symptoms like incontinence, tongue biting, and injuries are much more specific if they are documented rather than reported. Again, documented occurrence out of sleep is not the same as reported occurrence out of sleep. Most likely other "fashionable" unsubstantiated diagnoses such as "chronic fatigue" or Lyme disease have the same value. The examination, paying particular attention to mental status evaluation including the general demeanor and appropriate level of concern, overdramatization or hysterical features, can be very telling. Lastly, the examination often uncovers histrionic behaviors such as give-way weakness or tight-roping. Performing the examination can in itself act as an "activation" in suggestible patients, making a spell more likely to occur during the history taking or examination (16). By contrast to the above, certain symptoms, when present, argue in favor of epileptic seizures and should warrant caution.
