Bactrim side effects
The most common side effects caused by Bactrim are loss of appetite, nausea, vomiting, indigestion, dizziness, and ringing in the ears. It can also cause fatigue, insomnia, skin rash, and sensitivity to the sun.
While rare, Bactrim can cause more severe reactions. These include allergic reactions, low blood sugar, liver damage, kidney failure, anemias, and electrolyte imbalances. Antibiotics can alter the normal bacteria in the gastrointestinal tract, leading to a secondary infection called Clostridium difficile. This produces severe watery or bloody diarrhea. Get emergency care if you experience severe symptoms or signs of an allergic reaction.
