Side Effects of Spironolactone-HCTZ
Diarrhea or constipation, blurred vision, restlessness, and headache are some of the possible side effects of spironolactone-HCTZ. These side effects are minor in most cases and don't require treatment. However, you should seek medical attention immediately if you develop potentially serious spironolactone-HCTZ side effects, such as signs of low blood pressure (including dizziness or lightheadedness), gout, or breast lumps.
As with any medicine, side effects are possible with spironolactone-HCTZ (Aldactazide®); however, not everyone who takes the drug will experience side effects. In fact, most people tolerate it 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.
