Based on a clinical pharmacology study in 24 subjects with mild, moderate, and severe liver impairment [see Clinical Pharmacology (12.3)] , the following general recommendations can be made. In the same trial, the AUC and C max of Lamotrigine were similar following the addition of oxcarbazepine (600 mg twice daily) to Lamotrigine in healthy male volunteers compared with those receiving Lamotrigine alone. Cocaine or amphetamine toxicity in a patient Techniques to reduce positive margins in breast-conserving surgery Endocrine System If you have suicidal thoughts or actions, your healthcare provider may check for other causes. In the same study, coadministration of Lamotrigine (300 mg/day) in 16 female volunteers did not affect the pharmacokinetics of the ethinylestradiol component of the oral contraceptive preparation. Rare: Bursitis, muscle atrophy, pathological fracture, tendinous contracture. Lamotrigine tablets may cause a serious skin rash that may cause you to be hospitalized or even cause death. Taking the wrong medication can cause serious health problems. Experience in patients with hepatic impairment is limited. a Valproate has been shown to inhibit glucuronidation and decrease the apparent clearance of Lamotrigine [see Drug Interactions (7), Clinical Pharmacology (12.3)]. may cause aseptic meningitis, a serious inflammation of the protective membrane that covers the brain and spinal cord. Monotherapy in Adults with Epilepsy: The most commonly observed (5% for Lamotrigine tablets and more common on drug than placebo) adverse reactions seen in association with the use of Lamotrigine tablets during the monotherapy phase of the controlled trial in adults not seen at an equivalent rate in the control group were vomiting, coordination abnormality, dyspepsia, nausea, dizziness, rhinitis, anxiety, insomnia, infection, pain, weight decrease, chest pain, and dysmenorrhea. A Poison Control Center should be contacted for information on the management of overdosage of Lamotrigine tablets. The mean plasma half-lives determined in the study were 42.9 hours (chronic renal failure), 13.0 hours (during hemodialysis), and 57.4 hours (between hemodialysis) compared with 26.2 hours in healthy volunteers. In both trials, patients were titrated to a target dose of 200 mg of Lamotrigine tablets, as add-on therapy or as monotherapy with gradual withdrawal of any psychotropic medications during an 8- to 16-week open-label period. b Drugs that induce Lamotrigine glucuronidation and increase clearance, other than the specified antiepileptic drugs,include estrogen-containing oral contraceptives, rifampin, and the protease inhibitors lopinavir/ritonavir and atazanavir/ritonavir. Decreased Lamotrigine concentration approximately 40%. Keep Lamotrigine tablets and all medicines out of the reach of children. Because Lamotrigine is metabolized predominantly by glucuronic acid conjugation, drugs that are known to induce or inhibit glucuronidation may affect the apparent clearance of Lamotrigine. Storage: Store at 20C to 25C (68F to 77F); excursions permitted from 15C to 30C (59F to 86F) [see USP Controlled Room Temperature]. It is also used to treat [] Few patients with severe renal impairment have been evaluated during chronic treatment with Lamotrigine tablets. c The effect of other hormonal contraceptive preparations or hormone replacement therapy on the pharmacokinetics of Lamotrigine has not been systematically evaluated in clinical trials, although the effect may be similar to that seen with the ethinylestradiol/levonorgestrel combinations. A woman who had sex soon after birth might take a pregnancy test to get a false positive pregnancy test. Symptoms have been reported to occur within 8 to 24 days following the initiation of treatment. Lamotrigine tablets (200- and 400-mg/day treatment groups combined) were superior to placebo in delaying the time to occurrence of a mood episode (Figure 1). Top 4 causes of false negative pregnancy test. An effect of this magnitude is not considered to be clinically relevant. Lamotrigine is rapidly and completely absorbed after oral administration with negligible first-pass metabolism (absolute bioavailability is 98%). Following multiple administrations (150 mg twice daily) to normal volunteers taking no other medications, Lamotrigine induced its own metabolism, resulting in a 25% decrease in t and a 37% increase in CL/F at steady state compared with values obtained in the same volunteers following a single dose. Its chemical name is 3,5-diamino-6-(2,3-dichlorophenyl)- as-triazine, its molecular formula is C 9H 7N 5Cl 2, and its molecular weight is 256.09. HLH is a life-threatening syndrome of pathologic immune activation characterized by clinical signs and symptoms of extreme systemic inflammation. Measurement of serum progesterone indicated that there was no hormonal evidence of ovulation in any of the 16 volunteers, although measurement of serum FSH, LH, and estradiol indicated that there was some loss of suppression of the hypothalamic-pituitary-ovarian axis. Phase IV trials are used to detect adverse drug outcomes and monitor drug effectiveness in the real . Gradual transient increases in Lamotrigine plasma levels (approximate 2-fold increase) occurred during the week of inactive hormone preparation (pill-free week) for women not also taking a drug that increased the clearance of Lamotrigine (carbamazepine, phenytoin, phenobarbital, primidone, or other drugs such as rifampin and the protease inhibitors lopinavir/ritonavir and atazanavir/ritonavir that induce Lamotrigine glucuronidation) [see Drug Interactions (7)] . The precise mechanism(s) by which Lamotrigine exerts its anticonvulsant action are unknown. Pregnancy tests look for a special hormone human chorionic gonadotropin (HCG) that only develops in a person's body during pregnancy. Starting estrogen-containing oral contraceptives may significantly decrease Lamotrigine plasma levels and stopping estrogen-containing oral contraceptives (including the pill-free week) may significantly increase Lamotrigine plasma levels [see Warnings and Precautions (5.9), Clinical Pharmacology (12.3)]. The primary endpoint was TIME (time to intervention for a mood episode or one that was emerging, time to discontinuation for either an adverse event that was judged to be related to bipolar disorder, or for lack of efficacy). Pregnancy Tests. 9. In 2 small studies (n = 7 and 8) of patients with epilepsy who were maintained on other AEDs, there also was a linear relationship between dose and Lamotrigine plasma concentrations at steady state following doses of 50 to 350 mg twice daily. Summary. False-negative results can cause missed opportunities to detect misuse. Lamotrigine tablets can cause serious side effects. Lamotrigine tablets have been administered to 6,694 individuals for whom complete adverse reaction data was captured during all clinical trials, only some of which were placebo controlled. The greater the interval of time since the previous dose, the greater consideration should be given to restarting with the initial dosing recommendations. If you miss a dose of Lamotrigine tablets take it as soon as you remember. inflammation of the bladder. In Trial 2, patients received double-blind monotherapy with Lamotrigine tablets (100 to 400 mg/day, n = 59), or placebo (n = 70). The commonly prescribed antidepressant, trazodone, has been reported to cause false positives in 3,4-methylenedioxymethamphetamine (MDMA) UDSs. Infrequent: Allergic reaction, chills, malaise. It is very rare and is very unlikely causing your pregnancy test to be positive. Nervous System The pharmacokinetics of lithium were not altered in healthy subjects (n = 20) by coadministration of Lamotrigine (100 mg/day) for 6 days. The corpus luteum produces progesterone i X A female reproductive hormone that plays an important role in . Other side effects include: infection, dyspepsia, abnormal gait, constipation, and drowsiness. Data from in vitro studies indicate that Lamotrigine is approximately 55% bound to human plasma proteins at plasma Lamotrigine concentrations from 1 to 10 mcg/mL (10 mcg/mL is 4 to 6 times the trough plasma concentration observed in the controlled efficacy trials). Rare: Angioedema, erythema, exfoliative dermatitis, fungal dermatitis, herpes zoster, leukoderma, multiforme erythema, petechial rash, pustular rash, Stevens-Johnson syndrome, vesiculobullous rash. Dosing of Lamotrigine tablets should be based on therapeutic response [see Clinical Pharmacology (12.3)]. Estrogen-containing oral contraceptives and other drugs, such as rifampin and protease inhibitors lopinavir/ritonavir and atazanavir/ritonavir, that induce Lamotrigine glucuronidation have also been shown to increase the apparent clearance of Lamotrigine [see Drug Interactions (7)]. Monotherapy with Lamotrigine Tablets in Adults with Partial-Onset Seizures Already Receiving Treatment with Carbamazepine, Phenytoin, Phenobarbital, or Primidone as the Single Antiepileptic Drug. However, the embryo produces hCG and can cause a false-positive on a pregnancy test. The in vitro electrophysiological effects of this metabolite have not been studied. Figure 1: Kaplan-Meier Estimation of Cumulative Proportion of Patients with Mood Episode (Trial 1), Figure 2: Kaplan-Meier Estimation of Cumulative Proportion of Patients with Mood Episode (Trial 2). erythema or redness . In patients already taking maintenance doses of Lamotrigine tablets and not taking glucuronidation inducers, the dose of Lamotrigine tablets may need to be increased if atazanavir/ritonavir is added, or decreased if atazanavir/ritonavir is discontinued [see Clinical Pharmacology (12.3)]. The effectiveness of Lamotrigine in the maintenance treatment of bipolar I disorder was established in 2 multicenter, double-blind, placebo-controlled trials in adult patients (aged 18 to 82 years) who met DSM-IV criteria for bipolar I disorder. Because most trials included in the analysis did not extend beyond 24 weeks, the risk of suicidal thoughts or behavior beyond 24 weeks could not be assessed. Accordingly, doses above 200 mg/day are not recommended. Family. If other drugs are subsequently introduced, the dose of Lamotrigine tablets may need to be adjusted. increase your dose of Lamotrigine tablets faster than prescribed. Lamotrigine tablets 25 mg are available for oral administration as off white, round, flat faced, beveled edge tablets, debossed over score on one side and 60 on other side. Chemical pregnancies aren't a result of action or inaction by the woman but can occur because of: * Fibroids. If you take too much Lamotrigine, call your healthcare provider or your local Poison Control Center or go to the nearest hospital emergency room right away. It is associated with high mortality rates if not recognized early and treated. Because there is inadequate experience in this population, Lamotrigine tablets should be used with caution in these patients [see Dosage and Administration (2.1)] . The effectiveness of Lamotrigine tablets as adjunctive therapy (added to other AEDs) was initially established in 3 pivotal, multicenter, placebo-controlled, double-blind clinical trials in 355 adults with refractory partial-onset seizures. Adjunctive Therapy with Lamotrigine Tablets in Pediatric and Adult Patients with Primary Generalized Tonic-Clonic Seizures. Prior to initiation of treatment with Lamotrigine tablets, the patient should be instructed that a rash or other signs or symptoms of hypersensitivity (e.g., fever, lymphadenopathy) may herald a serious medical event and that the patient should report any such occurrence to a healthcare provider immediately. Plasma Concentrations of Lamotrigine The phase IV clinical study analyzes which people take Topamax and have Drug screen false positive. Lamictal may cause false positives in urine drug tests. In patients with epilepsy there is a possibility of increasing seizure frequency. Recommended dosing guidelines are summarized in Table 1. a Valproate has been shown to inhibit glucuronidation and decrease the apparent clearance of Lamotrigine [see Drug Interactions (7), Clinical Pharmacology (12.3)]. There have been reports of decreased Lamotrigine concentrations during pregnancy and restoration of pre-pregnancy concentrations after delivery. Adjustments to the Maintenance Dose of Lamotrigine Tablets in Women Taking Estrogen-Containing Oral Contraceptives. Last updated on Mar 1, 2023. When administered to pregnant rats, Lamotrigine decreased fetal folate concentrations at doses greater than or equal to 5 mg/kg/day, which is less than the human dose of 400 mg/day on a mg/m 2 basis. a type of stomach irritation called gastritis. swelling of your face, eyes, lips, or tongue, unusual bruising or bleeding, looking pale, yellowing of your skin or the white part of your eyes, seizures for the first time or happening more often, pain and/or tenderness in the area towards the top of your stomach (enlarged liver and/or spleen). Peak plasma concentrations occur anywhere from 1.4 to 4.8 hours following drug administration. Folate concentrations were also reduced in male rats given repeated oral doses of Lamotrigine. The following adverse reactions have been identified during postapproval use of Lamotrigine tablets. When used correctly, home pregnancy tests are 99% accurate. Lamotrigine tablets should not be used for acute treatment of manic or mixed mood episodes. No dosage adjustment is needed in patients with mild liver impairment. Concomitant use of other sodium channel blockers may further increase the risk of proarrhythmia. Addition of carbamazepine decreases Lamotrigine concentration approximately 40%. Lamotrigine is used alone or with other medicines to treat seizures in patients two years and older. Call your babys healthcare provider right away if you see any of these problems. Vd/F is independent of dose and is similar following single and multiple doses in both patients with epilepsy and in healthy volunteers. Evidence gathered from other sources suggests that self-induction by Lamotrigine may not occur when Lamotrigine is given as adjunctive therapy in patients receiving enzyme-inducing drugs such as carbamazepine, phenytoin, phenobarbital, primidone, or other drugs such as rifampin and the protease inhibitors lopinavir/ritonavir and atazanavir/ritonavir that induce Lamotrigine glucuronidation [see Drug Interactions (7)]. e Slight decrease, not expected to be clinically meaningful. Increased Lamotrigine concentrations slightly more than 2-fold. Drugs other than those listed above have not been systematically evaluated in combination with Lamotrigine. However, sometimes, there may be hCG in your urine even if you are not (or are no longer) pregnant with a viable . Metabolic and Nutritional Disorders Several meta-analyses have not reported an increased risk of major congenital malformations following Lamotrigine exposure in pregnancy compared with healthy and disease-matched controls. These tests can use either your pee or blood to look for HCG. In patients continuing to have at least 4 seizures per month during the baseline, Lamotrigine tablets or placebo was then added to the existing therapy. Plasma concentrations of Lamotrigine were not affected by concomitant lacosamide (200, 400, or 600 mg/day) in placebo-controlled clinical trials in patients with partial-onset seizures. Following a 4-week, single-blind, placebo phase, patients were randomized to 16 weeks of treatment with Lamotrigine tablets or placebo added to their current AED regimen of up to 3 drugs. Cold remedies, hay fever remedies, nasal decongestants, diet pills, fluoxetine (Prozac), methylphenidate (Ritalin), bupropion (Wellbutrin), beta blockers (blood-pressure remedies) Barbiturates. Do not change your dose without talking to your healthcare provider. Mean half-lives of Lamotrigine in subjects with mild, moderate, severe without ascites, and severe with ascites hepatic impairment were 46 20, 72 44, 67 11, and 100 48 hours, respectively, as compared with 33 7 hours in healthy controls [see Dosage and Administration (2.1)]. Patients should be made aware of and report cardiac signs or symptoms to their healthcare provider right away. When oral daily doses of Lamotrigine were given to pregnant rats during organogenesis, fetal, placental, and maternal folate concentrations were reduced. Lamotrigine tablets can cause serious side effects. The majority of Lamotrigine tablets pregnancy exposure data are from women with epilepsy. No dosage adjustment is needed in patients with mild liver impairment. Infrequent: Abnormal ejaculation, hematuria, impotence, menorrhagia, polyuria, urinary incontinence. In 1 trial, maximal inhibition of Lamotrigine clearance was reached at valproate doses between 250 and 500 mg/day and did not increase as the valproate dose was further increased. Human Data: Data from several international pregnancy registries have not shown an increased risk for malformations overall. Encourage women who are taking Lamotrigine tablets during pregnancy to enroll in the North American Antiepileptic Drug (NAAED) Pregnancy Registry by calling 1-888-233-2334 or visiting http://www.aedpregnancyregistry.org/. Animal Data: When Lamotrigine was administered to pregnant mice, rats, or rabbits during the period of organogenesis (oral doses of up to 125, 25, and 30 mg/kg, respectively), reduced fetal body weight and increased incidences of fetal skeletal variations were seen in mice and rats at doses that were also maternally toxic. Difficulty sleeping. Lamotrigine decreased fetal folate concentrations in rats, an effect known to be associated with adverse pregnancy outcomes in animals and humans (see Data). Because Lamotrigine is not highly bound to plasma proteins, clinically significant interactions with other drugs through competition for protein binding sites are unlikely. During the monotherapy phase of the double-blind placebo-controlled trials of 18 months duration, 13% of 227 patients who received Lamotrigine tablets (100 to 400 mg/day), 16% of 190 patients who received placebo, and 23% of 166 patients who received lithium discontinued therapy because of an adverse reaction. The median change in seizure frequency was a 26% reduction on Lamotrigine tablets compared with placebo (P<0.01). Urine samples can be adulterated with other substances to mask positive results on urine drug testing. Therefore, it is important that the dosing recommendations be followed closely. The dose increases should begin at the same time that the oral contraceptive is introduced and continue, based on clinical response, no more rapidly than 50 to 100 mg/day every week. For the intent-to-treat population, the median percent reduction in PGTC seizures was 66% in patients treated with Lamotrigine tablets and 34% on placebo, a difference that was statistically significant ( P = 0.006). A second trial (n = 98) was a double-blind, placebo-controlled, randomized, crossover trial consisting of two 14-week treatment periods (the last 2 weeks of which consisted of dose tapering) separated by a 4-week washout period. Each time you fill your prescription, check the tablets you receive against the pictures of the tablets below. Risk by Indication for Antiepileptic Drugs in the Pooled Analysis. Adverse Reactions in Pooled, Placebo-Controlled Adjunctive Trials in Pediatric Patients with Epilepsy, Table 12. Importantly, that drug is chemically unrelated to Lamotrigine. b Drugs that induce Lamotrigine glucuronidation and increase clearance, other than the specified antiepileptic drugs, include estrogen-containing oral contraceptives rifampin, and the protease inhibitors lopinavir/ritonavir and atazanavir/ritonavir. In patients discontinuing valproate, the dose of Lamotrigine tablets should be doubled over a 2-week period in equal weekly increments (see Table 6). There is no way to tell if a mild rash will become more serious. Isolated liver failure without rash or involvement of other organs has also been reported with Lamotrigine. Patients with Renal Impairment Actifed (pseudoephedrine and triprolidine) - false positive for Amphetamines. This information should not take the place of medical care and advice from your healthcare provider. People prescribed Lamotrigine tablets have sometimes been given the wrong medicine because many medicines have names similar to Lamotrigine tablets so always check that you receive Lamotrigine tablets. The Lamotrigine chewable/dispersible tablets were found to be equivalent, whether administered as dispersed in water, chewed and swallowed, or swallowed whole, to the Lamotrigine compressed tablets in terms of rate and extent of absorption. Limited clinical data suggest a higher incidence of headache, dizziness, nausea, and somnolence with coadministration of Lamotrigine and oxcarbazepine compared with Lamotrigine alone or oxcarbazepine alone. The median seizure frequency at baseline was 3 per week while the mean at baseline was 6.6 per week for all patients enrolled in efficacy trials. Keep a list of them to show your healthcare provider and pharmacist when you get a new medicine. The effects of doses of Lamotrigine other than 300 mg/day have not been systematically evaluated in controlled clinical trials. About lamotrigine Who can and cannot take it How and when to take it Side effects Pregnancy, breastfeeding and fertility Taking lamotrigine with other medicines and herbal supplements Common questions There were 4 suicides in drug-treated patients in the trials and none in placebo-treated patients, but the number of events is too small to allow any conclusion about drug effect on suicide. Discuss the benefits and risks of continuing breastfeeding. Dosage adjustments will be necessary in most patients who start or stop estrogen-containing oral contraceptives while taking Lamotrigine tablets [see Dosage and Administration (2.1)] . Concomitant AEDs which influence Lamotrigine clearance in adults were found to have similar effects in children. Incidence in Controlled Adjunctive Trials in Pediatric Patients with Epilepsy: Table 11. Hepatobiliary Tract and Pancreas Pancreatitis. Data from multiple small studies indicate that Lamotrigine plasma levels in nursing infants have been reported to be as high as 50% of maternal plasma concentrations. See your healthcare provider if you need to have your pregnancy confirmed. Common findings include fever, hepatosplenomegaly, rash, lymphadenopathy, neurologic symptoms, cytopenias, high serum ferritin, hypertriglyceridemia and liver function and coagulation abnormalities. Additionally, there have been rare cases of toxic epidermal necrolysis with and without permanent sequelae and/or death in US and foreign postmarketing experience. There is evidence that the inclusion of valproate in a multidrug regimen increases the risk of serious, potentially life-threatening rash in adults. Valproate + phenytoin and/or carbamazepine, Subjects taking carbamazepine, phenytoin, phenobarbital, or primidone, Subjects taking antiepileptic drugs with no known effect on the apparent clearance of Lamotrigine, Subjects taking carbamazepine, phenytoin, phenobarbital, or primidonea, manufacture(72888-025, 72888-026, 72888-027, 72888-028), analysis(72888-025, 72888-026, 72888-027, 72888-028), label(72888-025, 72888-026, 72888-027, 72888-028). Lamotrigine binds to melanin-containing tissues, e.g., in the eye and pigmented skin. Discontinuation of treatment may not prevent a rash from becoming life threatening or permanently disabling or disfiguring [see Warnings and Precautions (5.1)]. 1. Nervous System: Amnesia, ataxia, depression, hypesthesia, libido increase, decreased reflexes, increased reflexes, nystagmus, irritability, suicidal ideation. The apparent oral clearance of Lamotrigine was 25% lower in non-Caucasians than Caucasians. The highest dose tested is less than the human dose of 400 mg/day on a mg/m 2 basis. Your healthcare provider may change your dose. Adverse reactions that occurred with a frequency of less than 5% and greater than 2% of patients receiving Lamotrigine tablets and numerically more frequent than placebo were: Digestive: Anorexia, dry mouth, rectal hemorrhage, peptic ulcer. Answer Lamictal ( lamotrigine) has been reported to cause false positives for PCP (phencyclidine) on urine drug screenings. Instruct women to notify their healthcare providers if they plan to start or stop use of oral contraceptives or other female hormonal preparations. =Increased (inhibits Lamotrigine glucuronidation). In 18 patients with bipolar disorder on a stable regimen of 100 to 400 mg/day of Lamotrigine, the Lamotrigine AUC and C max were reduced by approximately 10% in patients who received aripiprazole 10 to 30 mg/day for 7 days, followed by 30 mg/day for an additional 7 days. In 339 patients aged 2 to 16 years with partial-onset seizures or generalized seizures of Lennox-Gastaut syndrome, 4.2% of patients on Lamotrigine tablets and 2.9% of patients on placebo discontinued due to adverse reactions. Generally, females receiving either Lamotrigine tablets as adjunctive therapy or placebo were more likely to report adverse reactions than males. Nearly all cases of life-threatening rashes caused by Lamotrigine tablets have occurred within 2 to 8 weeks of treatment initiation. See What is the most important information I should know about Lamotrigine tablets?. Increased Lamotrigine plasma levels could result in additional adverse reactions, such as dizziness, ataxia, and diplopia. Medication errors involving Lamotrigine tablets have occurred. Maintenance doses in patients weighing < 30 kg, regardless of age or concomitant AED, may need to be increased as much as 50%, based on clinical response. In patients receiving valproate alone, maintenance doses of adjunctive Lamotrigine tablets as high as 200 mg/day have been used. Inactive ingredients: colloidal silicon dioxide, magnesium stearate, microcrystalline cellulose and sodium starch glycolate. Effectiveness of Lamotrigine tablets in the acute treatment of mood episodes has not been established. It is a test result that is returned when a substance tests positive for another compound. Any expected or observed benefit of Lamotrigine in an individual patient with clinically important structural or functional heart disease must be carefully weighed against the risks for serious arrythmias and/or death for that patient. If hCG is detected, it typically means that the person is pregnantbut that's not always the case. The results given below are for all partial-onset seizures in the intent-to-treat population (all patients who received at least 1 dose of treatment) in each trial, unless otherwise indicated. Store Lamotrigine tablets at room temperature between 68 oF to 77 oF (20 oC to 25 oC). Adjunctive Therapy with Lamotrigine Tablets in Pediatric and Adult Patients with Lennox-Gastaut Syndrome. Lamotrigine tablets should be discontinued if an alternative etiology for the signs or symptoms cannot be established. Uridine 5-diphospho-glucuronyl transferases (UGT) have been identified as the enzymes responsible for metabolism of Lamotrigine. Amphetamine. There may be precautions to decrease the risk of this effect. This section provides specific dosing recommendations for patients older than 12 years and patients aged 2 to 12 years.
