Can I still use Amoxicillin that expired 2 months ago?

The problem isn't just that amoxicillin loses potency. An expired antibiotic can degrade in such a way that its residues become unpredictable - and this is especially important for antibacterial drugs, where you need an exact dose. If the tablet has partially crumbled or changed its properties during storage (even if you can't see it), you won't get the effect you need, and the bacteria may develop resistance.

Plus, two months isn't critical for a small deviation, but two months *after* the expiration date - that's already serious. Storage conditions in a home medicine cabinet (humidity, light, heat) speed up the drug's degradation. Even if the blister pack was sealed, chemical processes are happening inside.

Honestly, it's easier to just buy a new package than to deal with a flare-up or complications later. Amoxicillin isn't expensive, and it's not worth risking an infection - better to start treatment with a drug that's guaranteed to work.

You need to throw it away, but not because the tablet crumbles or changes color - that stuff might actually be invisible to the naked eye. Over two months after expiration, amoxicillin degrades unpredictably: some molecules break down, and some can turn into toxic compounds. Visually everything might look perfectly fine, but that doesn't guarantee it's safe.

The thing is, you can't gamble with antibiotics. If the concentration of the substance has dropped, the infection simply won't get treated, and you'll waste time. And if dangerous metabolites formed in the tablet (rare, but possible), you're risking unnecessary side effects. Why take the risk at all when you can grab a fresh one from the pharmacy for next to nothing?

If money's tight, go to a clinic - they'll run tests and tell you whether you even need treatment. Maybe the infection will clear up on its own without antibiotics, or maybe you'll need a completely different drug.
