It is available as a tablet, capsule, chewable tablet or oral solution.

Uses for Lamitrin

Lamitrin is used to treat a variety of seizures, such as:

• Generalized tonic-clonic seizures (grand mal): This seizure involves the body stiffening and shaking.

Lamitrin is also used to treat bipolar disorder to reduce episodes of mania, depression, and suicidal thoughts. Lamitrin may also be used to treat migraine headaches and pain associated with nerve damage.
