I started the medication, thinking I wasn't going to drink this weekend, but then my friend asked me to his formal, and there is little chance I'm not going to be able to drink. By the label and things I've seen on the site, I shouldn't mix the two. But would the drug become less effective if I paused my daily intake and continued the day after I drank?
Will metronidazole be less effective if I skip two days to drink and then finish the prescription?

Hi I’m thinking of doing this. Did you do it? How did it go?!

Hi i agree with the guys here. I know that attending a celebration often goes hand in hand with having a drink, but it really isn't worth interrupting the course of this medication. Also, and even more importantly, Metronidazole does not mix well with alcohol, it can cause a list of unpleasant and potentially dangerous side effects. You shouldn't drink alcohol until at least 3 days after taking your last tablet. Please be careful

It will reduce the effectiveness of the antibiotic and the antibiotic will kill the weakest bacteria leaving the more hardy bacteria to reproduce. Stopping for 2 days will allow the stronger bacteria to grow and you will, potentially, end up with a resistant infection. That would be a bad result as the antibiotic you are taking is for drug resistant infections already.
Why do you have to drink anyway; after all it is only 7 days? :)

Yes it would alter the effect. You can't stop and start meds like that. You can also develop an allergy to it when you do that. You can go out without drinking. I've managed it most of my life.
