Renal impairment Use caution; may consider reduce the dose in significant renal impairment

May be taken with or without food.

Hypersensitivity.

Hepatic or renal impairment. Closely monitor patient. Monitor children's body wt. Advise patient to report any hypersensitivity reaction. Avoid abrupt withdrawal unless severe skin reactions have developed. May impair ability to drive or operate machinery. Pregnancy and lactation. Serious skin rashes, Blood Dyscrasias, Suicidal Behavior, Aseptic Meningitis can occur in both adult and pediatric population. Lactation: Distributed into human breast milk; caution advised

Pregnancy Data from several prospective pregnancy exposure registries and epidemiological studies of pregnant women have not detected increased frequency of major congenital malformations or consistent pattern of malformations among women exposed to lamotrigine compared with the general population; the majority of exposure data are from women with epilepsy As with other AEDs, physiological changes during pregnancy may affect lamotrigine concentrations and/or therapeutic effect; there have been reports of decreased lamotrigine concentrations during pregnancy and restoration of pre-pregnancy concentrations after delivery; dose adjustments may be necessary to maintain clinical response Animal data In animal studies, administration of lamotrigine during pregnancy resulted in developmental toxicity (increased mortality, decreased body weight, increased structural variation, neurobehavioral abnormalities) at doses lower than those administered clinically Drug decreased fetal folate concentrations in rats, an effect known to be associated with adverse pregnancy outcomes in animals and humans Lactation Drug is present in milk from lactating women receiving therapy; neonates and young infants are at risk for high serum levels because maternal serum and milk levels can rise to high levels postpartum if lamotrigine dosage has been increased during pregnancy but is not reduced to pre-pregnancy dosage after delivery Glucuronidation is required for drug clearance; glucuronidation capacity is immature in the infant and this may also contribute to level of lamotrigine exposure; events including rash, apnea, drowsiness, poor sucking, and poor weight gain (requiring hospitalization in some cases) reported in infants who have been human milk-fed by mothers using lamotrigine; whether or not these events were caused by lamotrigine is unknown; no data are available on effects of drug on milk production Developmental and health benefits of breastfeeding should be considered along with mother’s clinical need for therapy and any potential adverse effects on breastfed infant from drug or from the underlying maternal condition Human milk-fed infants should be closely monitored for adverse events resulting from lamotrigine; measurement of infant serum levels should be performed to rule out toxicity if concerns arise; human milk-feeding should be discontinued in infants with lamotrigine toxicity

Metabolism enhanced by enzyme-inducing drugs e.g. phenytoin, carbamazepine, phenobarbitone, primidone, rifampicin, ethinyloestradiol/levonorgestrel combination. Metabolism reduced by sodium valproate.

Lamotrigine inhibits voltage-sensitive sodium channels, thereby stabilising neuronal membranes and consequently inhibiting pathological release of excitatory amino acids (e.g. glutamate and aspartate). These amino acids play a role in the generation and spread of epileptic seizures.
