Head-to-head comparisons of medication uses, side effects, warnings, and more.
Key takeaways
Hydrochlorothiazide (Microzide) and ethacrynic acid (Edecrin) are both diuretics, but they have some key differences. Hydrochlorothiazide is a thiazide diuretic mainly used to treat high blood pressure and swelling from fluid (edema). It is taken orally, usually once a day. Ethacrynic acid, on the other hand, is a loop diuretic primarily used for edema related to heart failure, cirrhosis, and kidney problems. It's especially used in people with sulfa allergies who cannot take hydrochlorothiazide and other similar medications. Ethacrynic acid can be taken orally or intravenously and is more expensive than other diuretics. While both medications can cause dizziness and electrolyte imbalances, ethacrynic acid has additional risks like temporary hearing loss and severe diarrhea. Hydrochlorothiazide may also cause skin sensitivity to sunlight and potential vision problems. Additionally, both medications are available as lower-cost generics.

Summary of Hydrochlorothiazide vs. Edecrin
Summary for Diuretic (water pill)
Prescription only
Hydrochlorothiazide is a diuretic or water pill. It helps lower blood pressure. It also helps with swelling from fluid buildup (edema) caused by some health conditions, like heart failure and kidney problems. People of all ages can take hydrochlorothiazide tablets and capsules. But children typically take much smaller, weight-based doses. You typically take your dose by mouth once (sometimes twice) daily, but avoid nighttime dosing so you won't wake up to urinate. Some common side effects are dizziness and urinating more often.

Prescription only
Ethacrynic acid, also known by its brand name Edecrin, is a strong diuretic (water pill) for treating edema (swelling). It's a loop diuretic that can be used for people who have a sulfa allergy and can't take other diuretics in the same drug class. Ethacrynic acid (Edecrin) is a tablet that's taken by mouth, but the specific dosage depends on the medical condition that's causing the edema. Common side effects include tiredness, headache, and loss of appetite.
