Why a generic substitute?

Same active ingredient

A substitute has the exact same salt(s) — so it works the same way as the brand.

Often much cheaper

Generics can cost a fraction of the branded price for the identical molecule.

Quality-regulated

All medicines we list are from licensed sellers and meet the same standards.

Substitutes share the same active ingredients, but always confirm the strength and form with your doctor or pharmacist before switching — especially for chronic, prescription or narrow-therapeutic-index medicines.
