I'm taking cloxacillin 500mg and Pen V 300mg, do I eat 30mins before or after?

Cloxacilline is a kind of penicillin.  To maximise it’s absorption, it has to be taken on an empty stomach which means 1h before breakfast, lunch and supper and at bedtime 2-3 hours after supper.  Since pen V is in the same family it is not intended to be taken at the same time.  You should check with your pharmacist with the indications — maybe he will reach the physician for only one antibiotic to treat you

The pharmacist is solely responsible for the answer.
