Common Use

Mysoline is a barbiturate used as an anticonvulsant to treat epilepsy, grand mal, psychomotor, and focal epileptic seizures. Its active ingredient, primidone, is metabolized into phenobarbital and phenylethylmalonamide (PEMA) in the body.

Dosage and Direction

Take this medication two to four times a day as prescribed. Always follow your doctor's instructions. Do not alter the dosage or stop treatment without medical advice. Avoid exceeding the recommended dose.

Precautions

Avoid alcohol and other central nervous system depressants while using Mysoline, as they may increase dizziness and drowsiness. Do not suddenly stop this medication without consulting your doctor, as it may lead to status epilepticus. Mysoline may cause suicidal thoughts. Notify your doctor if you experience anxiety, depression, mood changes, hyperactivity, agitation, or restlessness. Inform your healthcare provider if you are pregnant, breastfeeding, or planning to become pregnant, as this medication may cause excessive bleeding during delivery. Discuss any history of lung, liver, or kidney disease with your doctor.
