What is Phenytoin?

Phenytoin is a generic prescription drug that controls particular types of seizures in patients with epilepsy, a nervous system disorder characterized by recurrent seizures. Phenytoin is also used to prevent seizures in patients during or after neurosurgery. Phenytoin does not prevent all types of seizures.

Phenytoin belongs to a class of drugs called anticonvulsants. Epileptic seizures are caused by the repetitive, overexcited, and abnormal firing of nerve cells in the brain, which may be triggered by a situation or other stimulus. Phenytoin works by decreasing abnormal electrical activity in the brain.

Phenytoin is taken as a capsule, chewable tablet, oral suspension, or injection. Before taking Phenytoin, tell your healthcare provider about your medical history and any medical conditions you have. Tell your doctor if you are pregnant or planning to become pregnant. Phenytoin can interact with hormonal birth control, so discuss effective nonhormonal birth control with your provider before starting Phenytoin. Some people have suicidal thoughts while taking Phenytoin. You and your family/caregivers should be alert to any mood or behavior changes when you take Phenytoin. Phenytoin can cause gum swelling. Brush and floss your teeth and see your dentist regularly. Always wear a medical identification to let first responders know you have seizures, in case of an emergency. 

Phenytoin can interact with certain medications. Tell your provider about all of the medications you take, including Rx and OTC drugs, vitamins and supplements.

What are the side effects of Phenytoin?

The most common side effects of Phenytoin include, but are not limited to, headache, dizziness, upset stomach, nausea, vomiting, slurred speech, swollen glands, constipation, loss of balance, loss of coordination, confusion, and tremors. Serious side effects include liver problems and high blood sugar.

Allergic reactions are extremely rare but include hives, rashes, itching, and trouble breathing. These symptoms require emergency medical attention. Severe skinreactions are possible, including Stevens-Johnson syndrome, a drug reaction that causes dark rashes, blistering, and peeling throughout the skin as well as fever, sore throat, and flu-like symptoms. These symptoms require emergency medical attention. 

A rare complication of injected Phenytoin is Purple Glove Syndrome, which involves severe swelling, pain, and discoloration of the hands and feet and may require amputation. Other side effects may occur, as this is not a full list of side effects. Talk to your healthcare provider about side effects and how to address them.
