Switching From Penicillin To Azithromycin

I just finished taking penicillin vk 500mg and it was not working. I have some azithromycin 200mg. Is it ok to take this a day after stopping penicillin?

Hi Ashley,

I guess I can only speak for myself if I were in this type of predicament, but I would probably opt to take the azithromycin without worry if the penicillin wasn't working for me. I think that by waiting a day in between switching antibiotics, it should (in my opinion) be no different than continuing with the treatment regimen -of course, still following the prescribed dosing guidelines thereafter.

However, I would also look into taking a probiotic immediately after finishing the course of antibiotics to help replenish good bacteria in the body.

This is all theoretical based on what I would do for myself.

If in doubt, I recommend contacting your doctor and/or pharmacist for specific details on what to do from here on out, especially if the azithromycin also turns out to be inefficient for the strain of bacteria you're fighting against. Antibiotic resistance is becoming a major issue these days so I'd only follow through with azithromycin if I had a full 7-10 day course to complete or if I was able to follow up with my doctor soon after finishing penicillin or azithromycin to ensure that the bacteria was completely killed off. Otherwise, it can be a gamble... and I understand some people are willing to take that risk, but I just wanted to share my perspective on the situation at hand.

Hope this helps!
