It is a case of mistaken identity. Some clinicians have reported increased . Furthermore, a case-control study based on 21 congenital anomaly registries covering over 10 million births in Europe reported an adjusted odds ratio for isolated oral clefts with Lamotrigine exposure of 1.45 (95% CI: 0.8, 2.63). Decreased Lamotrigine concentrations approximately 50%. 1. Like other antiepileptic drugs, Lamotrigine tablets may cause suicidal thoughts or actions in a very small number of people, about 1 in 500. acting aggressive, being angry, or violent, an extreme increase in activity and talking (mania), other unusual changes in behavior or mood. Lamotrigine may cause aseptic meningitis, a serious inflammation of the protective membrane that covers the brain and spinal cord. Pooled analyses of 199 placebo-controlled clinical trials (monotherapy and adjunctive therapy) of 11 different AEDs showed that patients randomized to 1 of the AEDs had approximately twice the risk (adjusted Relative Risk 1.8, 95% CI: 1.2, 2.7) of suicidal thinking or behavior compared with patients randomized to placebo. Cerebrospinal fluid (CSF) analyzed at the time of clinical presentation in reported cases was characterized by a mild to moderate pleocytosis, normal glucose levels, and mild to moderate increase in protein. No specific dosing guidelines can be provided for conversion to monotherapy with Lamotrigine tablets with AEDs other than carbamazepine, phenytoin, phenobarbital, primidone, or valproate. Shaking or tremors. The overall adverse reaction profile for Lamotrigine tablets was similar between females and males and was independent of age. Several of these medications for mental disorders can lead to false positive tests. The effect of other hormonal contraceptive preparations or hormone replacement therapy on the pharmacokinetics of Lamotrigine has not been systematically evaluated. Rare: Anemia, eosinophilia, fibrin decrease, fibrinogen decrease, iron deficiency anemia, leukocytosis, lymphocytosis, macrocytic anemia, petechia, thrombocytopenia. Table 6. This may result in increased plasma levels of certain drugs that are substantially excreted via this route. This section provides specific dosing recommendations for patients older than 12 years and patients aged 2 to 12 years. Approximately 11.5% of the 1,081 pediatric patients aged 2 to 16 years who received Lamotrigine tablets as adjunctive therapy in premarketing clinical trials discontinued treatment because of an adverse reaction. In 10 male volunteers, rifampin (600 mg/day for 5 days) significantly increased the apparent clearance of a single 25-mg dose of Lamotrigine by approximately 2-fold (AUC decreased by approximately 40%). Measurement of infant serum levels should be performed to rule out toxicity if concerns arise. Importantly, that drug is chemically unrelated to Lamotrigine. abdominal pain stuffy nose All reported adverse reactions are included except those already listed in the previous tables or elsewhere in the labeling, those too general to be informative, and those not reasonably associated with the use of the drug.

Because of the possible pharmacokinetic interactions between Lamotrigine and other drugs, including AEDs (see Table 13), monitoring of the plasma levels of Lamotrigine and concomitant drugs may be indicated, particularly during dosage adjustments. Experience in patients with hepatic impairment is limited. 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. Metabolic and Nutritional Disorders 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.
