Hydrochlorothiazide (often abbreviated as HCTZ) is a thiazide diuretic commonly used to treat high blood pressure (hypertension) and edema (fluid retention). While it’s effective for many people, like all medications, hydrochlorothiazide can have side effects. If you’re considering a blog post on this topic, here’s a breakdown of the common, less common, and serious side effects of HCTZ:

Less Common Side Effects:
- Skin reactions: Rashes, sensitivity to the sun, or even more severe reactions like Stevens-Johnson syndrome (rare).

Serious Side Effects:
- Allergic Reactions: Symptoms can include rash, itching, swelling, severe dizziness, or trouble breathing.
