Congestive Heart Failure Home > Triamterene Side Effects
Weakness or fatigue, dry mouth, and sensitivity to the sun are possible complications that may occur with triamterene. Side effects that are potentially serious and should be reported to a healthcare provider include yellowing of the skin or eyes, signs of high potassium levels, or signs of an allergic reaction. Most people, however, experience no problems while taking this drug.
As with any medicine, side effects are possible with triamterene (Dyrenium®); however, not everyone who takes the medication will experience problems. 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 can be easily treated by you or your healthcare provider.
(This article covers many, but not all, possible side effects with triamterene. Your healthcare provider can discuss a more complete list of triamterene side effects with you.)
Triamterene has been studied thoroughly in clinical trials, in which a group of people taking the drug have side effects documented and compared to another group not taking the medicine. This way, it is possible to see what side effects occur, how often they appear, and how they compare to the group not taking the medicine.
In these studies, some of the possible triamterene side effects included:
- Weakness or fatigue
- Dry mouth (see Dyrenium and Dry Mouth)
- Nausea or vomiting
- Sensitivity to the sun.
