Possible alternatives in the same class
Drugs in the same therapeutic class, best-supplied first. These are not automatic substitutes: only your pharmacist or prescriber can judge whether a switch makes sense for you.
Data reflects reports manufacturers are legally required to file with Health Canada, republished with per-drug aggregation by rxstat. Estimated end dates are supplied by manufacturers and frequently change. This page describes drug supply only and is not medical advice; never stop or switch a medication without speaking to your pharmacist or prescriber.
