Ethotoin is used to prevent and control seizures. It is known as an anticonvulsant/antiepileptic drug. It works by reducing the abnormal electrical activity in the brain that causes seizures. It belongs to a class of drugs known as hydantoins.
How to use Ethotoin Tablet
Take this medication with food, usually 4-6 times a day or as directed by your doctor. Taking it with food or milk may help prevent an upset stomach.
The dosage is based on your medical condition and response to therapy. Your doctor may direct you to take a low dose at first, gradually increasing the dose to lower the chance of side effects such as upset stomach and drowsiness. Your doctor will adjust your dose to find the best dose for you. Follow your doctor's directions carefully.
Space your doses evenly throughout the day. It is important to take all doses on time to keep a steady level of medication in your blood. To help you remember, take it at the same times each day. Do not skip doses.
If you are already taking another anti-seizure drug, follow your doctor's directions carefully for stopping or continuing the old drug and starting ethotoin.
Do not stop taking this medication or any anti-seizure medication without consulting your doctor. Your seizures may become worse when the drug is suddenly stopped. Your dose may need to be gradually decreased.
Inform your doctor if your condition persists or worsens.
Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

A small number of people who take anticonvulsants for any condition (such as seizure, bipolar disorder, pain) may experience depression, suicidal thoughts/attempts, or other mental/mood problems. Tell your doctor right away if you or your family/caregiver notice any unusual/sudden changes in your mood, thoughts, or behavior including signs of depression, suicidal thoughts/attempts, thoughts about harming yourself.
Tell your doctor right away if any of these rare but very serious side effects occur: unusual bleeding/bruising, symptoms of infection (fever, chills, persistent sore throat), symptoms of anemia (tiredness, pale skin/fingernails, fast heartbeat), liver problems (e.g., severe stomach/abdominal pain, unusual weakness/tiredness, pale stools, dark urine, yellowing eyes/skin).
