Posted on Thu, 5 Feb 2015

Question: How long would a slight difficulty of breathing last after taking one 400 metronidazole five hours before dinner and having an ale with dinner

Answered by Dr. Suresh Heijebu (1 hour later)

Brief Answer:
Will last for 48hrs at the most

Detailed Answer:
Hi Sir.

I understand your query and concern.

Metronidazole can cause idiosyncratic reactions like difficulty in breathing (in your case) in few sensitive individuals.

This can be accelerated in presence of ale/yeast extracts due to superimposed drug interactions/metabolism.

In most cases, this effect of mild difficulty in breathing lasts for 24-48 hrs and will wane off gradually.

Thank you.
