Rantac OD 300 — Substitute FAQs

Are substitutes as effective as the original medicine?

Substitutes with the same active ingredient (salt) work in a similar way. However, inactive ingredients may differ. Always consult your doctor before switching.

Why are some substitutes cheaper?

Generic medicines are usually cheaper because manufacturers don't have the same development costs as the original brand. They contain the same active ingredient in the same strength.

Can I switch to a substitute on my own?

No. Always consult your doctor or pharmacist before switching medicines, even if the substitute has the same composition.

What is the difference between generic and branded medicines?

Generic medicines contain the same active ingredients as branded ones but are sold under different names, often at lower prices. Both are regulated for safety and efficacy.
