Primidone (250mg)

Primidone (250mg) — Uses and Benefits

Primidone is mainly used to treat epilepsy and certain types of tremors.

WHAT THIS MEDICINE IS USED FOR

• Controlling generalized tonic-clonic (grand mal) seizures
• Controlling partial (focal) seizures
• Managing essential tremor in some patients

HOW IT WORKS

• It is converted in the liver into phenobarbitone and PEMA, both active substances
• These substances reduce abnormal electrical activity in the brain
• This helps prevent the spread of seizure activity and reduces tremor

WHAT IT IS NOT USED FOR

• It is not a painkiller and does not treat headaches
• It is not used for anxiety or sleep disorders as a first choice
• It is not a cure for epilepsy; it only controls symptoms
• It is not meant for occasional or as-needed use — it works best when taken regularly as prescribed
