Same salt, different brand — what does that mean?

A substitute contains the same active ingredient (salt), in the same strength, as Zofer Syrup. The medicine inside is the same — the brand name, manufacturer and price are what differ.

All medicines sold in India, branded or generic, must meet the quality standards set by the national drug regulator (CDSCO). A lower price does not mean lower quality.

Please confirm with your doctor or pharmacist before switching brands — they will check that the strength and form match your prescription.

Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.

Take it as soon as you remember. If your next dose is almost due, skip the one you missed — never take two doses together to catch up.
