Can antibiotics cause constipation?
Medically reviewed by Drugs.com. Last updated on Oct 22, 2020.
In general, the more common side effect with antibiotic treatment is gas and diarrhea caused by the antibiotic altering the normal flora of bacteria in your large intestine.
However, if you find that you are constipated by any medication, consider increasing your fluid and fiber intake and daily exercise to help keep your bowels moving.
In general, you should be able to take an over-the-counter stool softener or other laxatives on a short-term basis, if needed. However, ask your doctor or pharmacist for advice before combining any two medications.
