Can you take Tamiflu if im allergic to penicillin?

No. Tamiflu is an anti-viral drug while aspirin is an NSAID (used for inflammation) and penicillin is an antibiotic (doesn't treat viral infections). There's no reason why Tamiflu should contain aspirin or penicillin.

However, don't confuse Tamiflu with TM-FLU (completely different drug) which appears to contain penicillin and is a scam/fraudulent product. Do not use TM-FLU.

For more info on the TM-FLU scam see the related question below in the related links section.
