Dr. Evans Prieston answered

Specializes in Pharmacology

Zithromax: While it's always best to follow the directions which call for a tablet every 24 hours, taking your dose reasonably close to every 24 hours is optimal. If you are a few hours early or late should not have a therapeutic significance. However, it's always best to follow the directions as close as reasonably possible.
