Question : I finish taking a 10 days of cefdinir for sinus. How long do I have to wait to drink a few beers(2-4)? I am 34 and seems to be in fine health.

it has been 19 hours since I last took it and going to party, you think I should be fine?

Brief Answer:
About 1 day.

Detailed Answer:
Hello and welcome,

Cefdinir has a "half-life" of about 2 hours in people who have normal kidney function (much longer in people who have some kidney impairment.

A half-life of 2 hours means that 2 hours after taking the last dose, 1/2 of that last dose remains in your system. After 2 more hours, 1/4 remains in your system. And so on.

I would recommend waiting between 12 - 24 hours after the last dose before drinking alcohol.

Brief Answer:
That should be ok.

Detailed Answer:
That should be ok if you are feeling well. Since you've been sick recently, I'd suggest limiting the beers to 2 so that you don't stress your immune system right now.

Have a good time at the party!
Best regards,
