Side Effects of Triamterene-HCTZ
Some commonly reported side effects of triamterene-HCTZ include dizziness, a dry mouth, nausea, and fatigue. However, these side effects are typically minor and easily treated -- and not everyone taking the drug will experience them. There are other triamterene-HCTZ side effects that should be reported immediately to your healthcare provider, such as an unexplained rash, difficulty breathing, and fainting spells.
As with any medicine, side effects are possible with triamterene-HCTZ (Dyazide®, Maxzide®); however, not everyone who takes the drug 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 can easily be treated by you or your healthcare provider.
(This article covers many, but not all, possible side effects with triamterene-HCTZ. Your healthcare provider can discuss a more complete list of triamterene-HCTZ side effects with you.)
Triamterene-HCTZ has been studied thoroughly in clinical trials. In these studies, the side effects that occur in a group of people taking the drug are documented and are then compared to side effects that occur in another group of people 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.
Based on these studies, some of the possible triamterene-HCTZ side effects include:
- Changes in vision or eye pain
- Nausea, vomiting, and loss of appetite
- Diarrhea or constipation
- Drowsiness and fatigue
- Dizziness or vertigo (a sense of spinning)
- Dry mouth (see Dyazide and Dry Mouth or Maxzide and Dry Mouth)
- Depression (see Maxzide and Depression)
- Vision changes, including blurred vision
- Sensitivity to the sun
- Impotence (see Dyazide and Impotence).
