Zyloprim Side Effects
Clinical studies have shown that diarrhea, nausea, and gout attacks were the most common side effects reported with Zyloprim. Side effects of the medication are generally mild and, in most cases, easy to treat. It is possible, however, to develop serious side effects with Zyloprim that require immediate medical attention, such as blood in the urine, painful urination, or a skin rash.
As with any medicine, Zyloprim® (allopurinol) can cause side effects. However, not everyone who takes the medication will experience side effects. In fact, most people tolerate it quite well. If side effects do occur, in most cases, they are minor and either require no treatment or are easily treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with Zyloprim. Your healthcare provider can discuss a more complete list of Zyloprim side effects with you.)
Zyloprim has been thoroughly studied 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 not taking the medicine. 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.
In these studies, the most common Zyloprim side effects (occurring in more than 1 percent of people) included:
Less-common side effects (occurring in less than 1 percent of people) that were thought to be related to Zyloprim included:
- Indigestion or heartburn
- Muscle pain
- Joint pain
- Unusual sensations (such as burning, pricking, or tingling) in the hands or feet
- Hair loss
- Taste changes or loss of taste.
