Fluoxetine capsules are indicated for the treatment of: Acute and maintenance treatment of Major Depressive Disorder [see Clinical Studies (14.1) ] .

Equivalent pills — same medicine, different imprint

The pills below contain the same active ingredient at the same strength (Fluoxetine 20 mg). Different makers stamp their own codes, so equivalent pills often look completely different. This is factual label information — it is not a suggestion to substitute one product for another; only a pharmacist or prescriber can advise on that.

What does the E 91 pill look like?

How can I be sure this identification is right?

Check every characteristic — imprint (both sides), colour, shape, size and score — against the pill in your hand. If all of them agree, the pill matches the FDA label shown here, but that is still not a guarantee: counterfeit pills copy real imprints. A pharmacist can confirm the identification in person, and you should never take a pill you are not certain about.
