What is phenobarbital used for in dogs and cats?

Phenobarbital is commonly prescribed by veterinarians to help manage seizures and epilepsy in dogs and cats. It belongs to the barbiturate class of anticonvulsants.

How do I give the 20 mg/mL compounded solution?

Measure the exact volume prescribed by your veterinarian using a calibrated oral syringe, then administer it by mouth. The 20 mg/mL concentration helps ensure accurate dosing for pets of different sizes.

Can I stop giving phenobarbital if my pet’s seizures improve?

No. Stopping suddenly can lead to breakthrough seizures. Consult your veterinarian before making any changes to the dosing schedule.

What side effects should I watch for?

Commonly observed effects may include drowsiness, unsteadiness, increased thirst or urination, and increased appetite, especially when starting therapy or after dose adjustments. Contact your veterinarian if side effects are severe or persistent.

How long does it take to see results?

Some pets show an effect after dosing begins, but achieving stable seizure control may require time and veterinary monitoring. Follow your veterinarian’s guidance and recommended rechecks.

How should I store this medication?

Follow the storage directions on your prescription label. Keep the cap tightly closed and store out of reach of children and other animals.
