What it means
A group of drugs that calm overactive electrical activity in the brain. Examples are levetiracetam (Keppra), phenytoin (Dilantin), carbamazepine (Tegretol), valproic acid (Depakote), lamotrigine (Lamictal) and lacosamide. Several are also used for nerve pain and as mood stabilizers in bipolar disorder. Many cause drowsiness and interact with other drugs.
For the nurse
Give doses on time and teach the client never to stop suddenly, which can bring on seizures. Some need blood levels checked (phenytoin's usual range is 10–20 mcg/mL). Teach clients not to drive until cleared, to avoid alcohol, and to tell the provider about pregnancy plans, since some cause birth defects.
