Is ampacillian or penicillin?

Is penicillin good to take if you have a uti ?

Answer 1

Hi Brenda,

Unfortunately, penicillin (nor ampicillin) will help treat a UTI.

There are different kinds of bacteria out there…UTIs are usually caused by a “gram negative” bacteria.

Penicillin/amoxicillin do not treat “gram negative” bacteria well.
And most UTIs are completely resistant to ampicillin (so ampicillin would not help either).

Cheap medications that would treat most UTIs are:
1. Bactrim generic
2. Cipro generic
3. Macrobid generic

Hope this helps!
