Dilantin , also medically known as phenytoin, is a hydantoin anticonvulsant used to treat certain types of convulsions and seizures associated with epilepsy. It works by acting on the brain and the central nervous system to reduce the severeness and frequency of epileptic seizures.
Dilantin comes as an oral capsule, a chewable tablet and a liquid taken by mouth, two to three times daily.
Common side effects of Dilantin include headache, drowsiness, nervousness, insomnia, upset stomach, stomach pain, constipation, vomiting, blurred vision, mental confusion, irritation of the gums, loss of appetite, weight loss, and trouble in swallowing.
Dilantin may also be used to treat other conditions, as determined by your doctor.
