Questran Side Effects
Common side effects with Questran include loss of appetite, diarrhea, burping, and unexplained rash. Rare side effects include teeth problems, diverticulitis, or allergic reaction. You should notify your healthcare provider immediately if you experience bloody or black, tarry stools; unexplained muscle pain, tenderness, or weakness; difficulty swallowing; or severe stomach pain with nausea or vomiting. These Questran side effects may require immediate medical attention.
As with any medicine, side effects are possible with Questran® (cholestyramine). However, not everyone who takes the medicine will experience side effects; in fact, most people tolerate the drug well. When people do develop Questran side effects, they are generally minor and either require no treatment or can easily be treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Questran. Your healthcare provider can discuss a more complete list of Questran side effects with you.)
