Cannot find your medicine?
The list is not exhaustive. Ask your pharmacist to confirm the generic name and help you locate the Canadian product information.
A brand name used outside Canada may differ from the name on your prescription.
Names alone do not tell the whole story.
The strength, dosage form and release characteristics matter. A liquid, a regular tablet and an extended-release tablet may have different instructions.
Ask your pharmacist before changing formulations, crushing tablets or opening capsules. Follow the instructions for the product actually prescribed.
Different Treatment Roles
Daily treatment and rescue medication
Some medicines are used regularly to reduce seizures. Others are prescribed for particular emergencies or seizure patterns. A medicine’s role can depend on its formulation and the individual plan.
Use rescue medication only according to the prescribed instructions and training.
