Summary
Primidone is used to treat seizures, which are sudden bursts of electrical activity in the brain. It's effective for epilepsy, a disorder characterized by recurrent seizures. It may also be used for other conditions as determined by your doctor.
Primidone works by stabilizing electrical activity in the brain, which helps prevent seizures. It belongs to the barbiturate class of drugs, which act as central nervous system depressants, reducing the intensity of signals that can lead to seizures.
The usual starting dose for adults is 100 to 125 mg at bedtime, gradually increasing to 250 mg three to four times a day. The maximum recommended dose is 500 mg four times a day. It's taken orally, with or without food.
Common side effects include dizziness, drowsiness, and nausea. These effects are usually mild and may improve as your body adjusts to the medication. If they persist or worsen, contact your doctor.
Primidone can cause drowsiness and dizziness, affecting tasks requiring alertness. Avoid alcohol, as it can increase these effects. It's contraindicated in people with porphyria, a group of disorders affecting the skin or nervous system. Always inform your doctor about your medical history.
