I'm on metronidazole for a bacterial infection 500 mg. I took my last pill on Thursday morning. Can I drink tonight?

I'm on metronidazole for a bacterial infection 500 mg. I took my last pill on Thursday morning. Can I drink tonight?

Not a great idea: If ur just getting over an infection, ur body has been working hard with the help of those antibiotics to get 'you' better. Drinking alcohol is not really a good idea. There is a known drug reaction with alcohol. That said, the 'half-life' of metronidazole is relatively short, so after a few days it is washed out of ur system. Still, I would be against 'partying' after what you've just been thru. ...Read more

I have this thing on my arm. It came last summer and my doctor told me its bacterial infection. I used bactroban (mupirocin) on it.it fades but comes back randomly.

Could be MRSA: Methicillin-resistant Staph aureus (MRSA) is a type of bacteria that can cause skin lesions that are difficult to get rid of. If the skin lesion gets better with Bactroban but comes back, it may be due to MRSA infection. The appearance of MRSA skin lesions can vary a great deal. Septra DS or Bactrim (sulfamethoxazole and trimethoprim) DS taken by mouth for 10 – 14 days will usually get rid of an MRSA skin infection. ...Read more

What our risks and symptoms related to prolonged bacterial infection that is systemic from tooth abscess and infections. Over 2 years?
