Hydrochlorothiazide — Nutrient Depletion & Health Patterns
Also known as: Hydrochlorothiazide (HCTZ, Microzide)
Drug Class: Thiazide diuretic
First-line thiazide diuretic used for hypertension, edema, and heart failure. Works by inhibiting sodium-chloride reabsorption in the distal tubule, promoting sodium and water excretion. The most prescribed antihypertensive diuretic in the US. Also used in combination products (lisinopril/HCTZ, valsartan/HCTZ, losartan/HCTZ).
Nutrients That Hydrochlorothiazide May Deplete
Long-term use of Hydrochlorothiazide is associated with lower levels of the following nutrients based on peer-reviewed clinical research. WePattern surfaces these patterns from its clinical Knowledge Graph.
- Potassium
- Magnesium
- Sodium
- Zinc
- Vitamin B1 (Thiamine)
- Phosphorus
- CoQ10
Common Side Effects of Hydrochlorothiazide
- Low potassium (muscle cramps, weakness, heart palpitations)
- Low magnesium (muscle spasms, anxiety, insomnia)
- Elevated blood sugar
- Elevated uric acid (gout trigger)
- Increased triglycerides
- Frequent urination (especially early)
- Dizziness / low blood pressure on standing
- Sun sensitivity (photosensitivity rash)
Key Drug Interactions — Hydrochlorothiazide
Hydrochlorothiazide has 9 documented drug-drug interactions in WePattern's Pattern Health Intelligence database. Key interactions include:
- ACE inhibitors (used together but can cause severe potassium swings)
- NSAIDs (reduced antihypertensive effect + kidney strain)
- Lithium (HCTZ causes lithium toxicity — serious)
- Digoxin (low potassium increases digoxin toxicity)
- Diabetes medications (HCTZ raises blood sugar)
- Cholesterol medications (HCTZ raises triglycerides)
Frequently Asked Questions
