Jessica G: Doctors often advise not to mix alcohol and antibiotics and there is good reason for this. Excessive alcohol (like at that New Years Eve party with your friends) can interfere with your immune system, cause dehydration and prolong your illness.
But there are really only a few antibiotics that alcohol affects. They are: Metronidazole (Flagyl)
the side-effects include flushing, breathlessness, headache, increased or irregular heart rate, low blood pressure, nausea and vomiting.
Trimetheprim/Sulfa (Bactrim, Septra) similar side-effects are possible
and some rare antibiotics like:
Antimalarial Quinacrine (Atabrine)
Bottom line, if you are not on the above antibiotics, you can have a celebratory drink on New Years Eve. Stay hydrated and sleep in the next day do help recovery. Happy New Years!
