How these prices work

Prices come from each pharmacy's own website, or for Mercury Drug, from what their branches report to DOH. Each price links to the pharmacy's page, so you can check it before you buy.

One product per table. Every price in a table is for the same active ingredient, strength, and dose form. Prices are per tablet, capsule, or lozenge, per mL for liquids, lotions, shampoos, and pens, per gram for creams, and per piece for single doses: an ampoule, vial, syringe, sachet, nebule, or patch.

This is price information, not medical advice. Talk to your doctor or pharmacist before switching between a brand and its generic.
