Side effects of UTI antibiotics

Reviewed by Dr Jonah Mink, April 21'25 sec read

Like most antibiotics, the antibiotics that are commonly used to treat UTIs can lead to side effects in some people. The most common side effects tend to affect the digestive system and include nausea, vomiting, diarrhoea, bloating, indigestion, abdominal pain and loss of appetite. Most people tolerate these side effects, which usually disappear promptly upon finishing the course of antibiotics. If you experience severe side effects, you should seek medical advice. 

Less commonly, antibiotics can cause allergic reactions. If you think you may be having an allergic reaction to antibiotics like a rash, chest tightening, trouble breathing, you should seek medical attention immediately.
