Bladder Home > Elmiron Side Effects
Some of the most common side effects of Elmiron include abdominal pain, indigestion, and an increase in liver enzymes. Not everyone who takes this drug will experience problems -- most people have no issues with it. However, there are more serious (but rare) side effects to be aware of; these include vomiting, mouth ulcers, and gum bleeding.
As with any medicine, side effects are possible with Elmiron® (pentosan polysulfate sodium). However, not everyone who takes the drug will experience side effects. If people do develop side effects, in most cases, they are minor and either require no treatment or are easily treated by a healthcare professional. In studies, about 1.5 percent of people had a serious side effect while taking Elmiron 100 mg capsules.
(This article covers many, but not all, of the possible Elmiron side effects. Your healthcare provider can discuss a more complete list of side effects with you.)
Elmiron has been studied thoroughly in clinical trials. In these studies, the side effects that occurred in a group of people taking the drug were documented and then compared to the side effects that occurred in another group of people taking a placebo (a "sugar pill" that does not contain any active ingredients). As a result, it was possible to see what side effects occurred, how often they appeared, and how they compared to the group not taking the medicine.
The most common Elmiron side effects (occurring in approximately 1 percent to 4 percent of people) include:
- Hair loss
- Blood in the stool
- Unexplained rash
- Abdominal pain (stomach pain)
- Increase in liver enzymes
