Side Effects of Chlorothiazide
Possible side effects of chlorothiazide include diarrhea or constipation, blurred vision, and loss of appetite. Although most reported side effects are minor and don't require medical attention in most cases, it is important to notify your healthcare provider immediately if you develop any serious chlorothiazide side effects, such as an allergic reaction, fainting spells, or any signs of dehydration.
As with any medicine, there are possible side effects with chlorothiazide (Diuril®); however, not everyone who takes the medicine will experience side effects. In fact, most people tolerate chlorothiazide well. When 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, of the possible side effects with chlorothiazide. Your healthcare provider can discuss a more complete list of chlorothiazide side effects with you.)
Chlorothiazide 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, possible chlorothiazide side effects included:
- Diarrhea or constipation
- Nausea or vomiting
- Loss of appetite
- Vertigo (a sense of spinning)
- Blurred vision or other vision problems
- High cholesterol or high triglycerides
- Impotence (see Chlorothiazide and Impotence).
