I was told i could take azithromycin for a wisdom tooth infection. i have a sealed but expired z-pack ... is it okay to take?

Told?: In this era of social media, "told" means so may things. Please get it evaluated to make sure you have a treatable bacterial infection and (if so) your doc will give you a prescription for a fresh antibiotic appropriate to your situation. Not all pain is infection related so my advice is to actually address the problem with your wisdom teeth as even a round of abx really only abates symptoms.

How long exp???: You forgot to include the exp. date!!!!!! !0 years ago? 10 weeks ago? Most, not all, meds are effective long after their expiration dates, which are arbitrary. A more interesting question is the nature of the problem and a question about best therapy.

See below: See your dentist for definitive treatment and follow through. An antibiotic will only help on a temporary basis.

Outdated medications: Will not harm you, but efficacy the medication increases exponentially as you pass the expiration date. Antibiotics limit spread of dental infections by definitive dental treatment is required to affect a cure. See a wisdom tooth expert, and Oral Surgeon, for evaluation and appropriate treatment.
