Had severe head injury in 1971, but no after effects until 2014. Since then, suffered epileptic seizures and was proscribed lamotrigine for relief. Initial prescription was 100mg, twice a day, but gradually increased. However, even though take taken for years, last level of 250mg became too high. In September and December I suffered from dizziness, loss of balance, vertigo. Dosage was lowered to 200mg twice a day. Now advised to include another medication, such as Keppra, as protection from seizures. Lower dosage of lamotrigine is presumed less protective.
