Should i take expired amoxicillin? what are the risks of doing so?

Yes and no: All drugs must have an expiry date on them. That means the maker knows the drug will deliver the dose stated on the package. After that date the dose may or may not be as stated. I said yes and no because if it just 3 or 4 months outdated it should be ok but longer than that you should not use it. That drug may be used for critical infection whereas an outdated tylenol (acetaminophen) is not a critical drug.
