What is Celontin?

Celontin is a generic prescription drug that controls seizures in patients with absence epilepsy, which used to be called petit mal epilepsy. Absence epilepsy is a nervous system disorder that causes brief seizures that usually last fewer than 15 seconds. Absence seizures sometimes involve loss of consciousness and some muscle movements, but they do not involve convulsions or whole-body convulsions. Absence seizures are sometimes barely noticeable.

Celontin belongs to a class of drugs called anticonvulsants. An epileptic seizure is a cascade of uncontrolled and hyper-excited firing of nerve cells in the brain. Seizures are usually triggered by a situation or other stimulus. Celontin, like other anticonvulsants, reduces the brain's excitability, making it less vulnerable to the uncontrolled cascade of the repetitive firing of nerves.

Celontin is taken as a tablet or oral solution once or twice daily. Absence epilepsy is more common among children, so Celontin is usually prescribed to children. An oral solution is easier for younger children to take.

What are the side effects of Celontin?

The most common side effects of Celontin include, but are not limited to, headache, dizziness, upset stomach, nausea, stomach pain, abdominal pain, diarrhea, weight loss, loss of balance, loss of coordination, and feeling tired.

Allergic reactions are extremely rare but include hives, rashes, itching, and trouble breathing. Severe allergic reactions are possible, including a lupus-like reaction (fever, joint pain, swollen glands) or Stevens-Johnson syndrome, a drug reaction that causes dark rashes, blistering, and peeling throughout the body as well as fever, sore throat, and flu-like symptoms.

Mood and mental changes are possible. These include confusion, instability, aggression, depression, and, rarely, suicidal thoughts.
