Specifications: Each tablet contains 50 or 250 milligrams of primidone.

Conditions of use:

Dogs

Amount: 25 milligrams of primidone per pound of body weight (55 milligrams per kilogram of body weight) daily.

Indications: For the control of convulsions associated with idiopathic epilepsy, epileptiform convulsions, viral encephalitis, distemper, and hardpad disease that occurs as a clinically recognizable lesion in certain entities in dogs.

Limitations: The tablets may be administered whole or crushed and mixed with the food. When convulsions are frequent, the dosage should be divided and administered at intervals. Reduction in dosage should be made gradually and never be abruptly discontinued. Do not use in feline species, as primidone appears to have a specific neurotoxicity in cats.
