Lamotrigine 25mg is an anticonvulsant and mood-stabilizing medication used to treat epilepsy and bipolar disorder. It works by affecting the transmission of electrical signals in the brain, helping to stabilize mood and prevent seizures. Lamotrigine is effective in the treatment of partial seizures, generalized seizures, and Lennox-Gastaut syndrome, a severe form of epilepsy. It is also widely used for the maintenance treatment of bipolar disorder, particularly in preventing manic and depressive episodes. Lamotrigine works by inhibiting the release of glutamate, a neurotransmitter that plays a role in excitability within the brain, thereby helping to stabilize nerve activity. While Lamotrigine is generally well-tolerated, it can cause side effects such as rash, dizziness, and headache. Rare but serious side effects include a severe allergic reaction known as Stevens-Johnson syndrome, which may require discontinuation of the drug. Regular monitoring is recommended during the first few months of treatment to detect any early signs of adverse reactions. Lamotrigine should be gradually tapered off to avoid withdrawal symptoms.
