Buying from a pharmacy outside the U.S.? Read Is it safe to order Dyazide from Canada?
90-day cost = 90 capsules at the usual dose of 1 a day, bought as one order of whole packs with one shipping fee. 90-day cost is worked out from each pharmacy's real order size so different pack sizes compare fairly. Orders are kept within a 3-month supply (92 days); a pack that is larger than that is marked and not used for the lowest price at the top of this page. Prices checked Nov 11, 2026 on each pharmacy's website, in U.S. dollars. Savings compare with the U.S. list price. The lowest price at the top of this page uses only packs whose maker the pharmacy names, or whose product country and ships-from country it states. Price is the pharmacy's own price for one pack, as shown on its website (converted to U.S. dollars when it prices in Canadian dollars). Delivery is the pharmacy's own estimate for the shipping option shown, not a promise; some pharmacies count from when they receive your prescription or ship the order. Total = the packs needed + shipping. When those packs don't add up to exactly 90 days, the row shows what that order costs and, under it, what it works out to for 90 days; we sort by the 90-day amount so pack sizes compare fairly. Prices change often; confirm at checkout. U.S. rows: the cash price a U.S. pharmacy published on its own website on the date shown, for whole fills, plus its standard shipping; no insurance or discount cards.

- Medicare Extra Help: if you have Medicare and limited income, Extra Help lowers what you pay for prescriptions. (Social Security)

Yes. The FDA has approved generic triamterene and hydrochlorothiazide 37.5/25 mg capsules from several companies, including Sandoz, Lannett, Zydus (Cadila), Biocon, Rubicon and others. Sandoz's generic was approved on June 5, 1997, and is still listed for sale. The FDA lists brand Dyazide as discontinued in the U.S.

What is Dyazide used for?
Dyazide combined triamterene, a potassium-sparing diuretic, with hydrochlorothiazide, a thiazide diuretic. Both are "water pills." According to the FDA label for the generic capsules (DailyMed), the medicine is used:
- To treat high blood pressure or swelling from fluid (edema) in people who develop low potassium on hydrochlorothiazide alone.
- For people who need a thiazide diuretic and can't risk low potassium.
The capsules contain 37.5 mg of triamterene and 25 mg of hydrochlorothiazide. The label's usual dose is one or two capsules once a day. It carries a boxed warning about high potassium (hyperkalemia), which can be fatal if it isn't corrected; the risk is higher in people with kidney problems or diabetes and in older or very ill people, and the label calls for regular potassium blood tests. The label says it is not a first treatment for most people. Your prescriber decides which medicine is right for you.
Is it safe to order Dyazide from Canada?
Many Americans do, but U.S. law and customs rules apply, and for Dyazide, compare the U.S. price of FDA-approved generic triamterene and hydrochlorothiazide before you order. Federal law generally doesn't allow individuals to import prescription drugs, though under its personal importation policy the FDA has long used enforcement discretion for some personal-use shipments, generally no more than a three-month supply (FDA). Congress has said enforcement against individuals should focus on imports that pose a significant threat to public health (Federal Food, Drug, and Cosmetic Act section 804(j)(1), 21 U.S.C. 384(j)(1)). You need a prescription from your doctor. New U.S. Customs rules for mailed orders start January 20, 2027. Health Canada lists Dyazide as cancelled since 2001 (Health Canada), so Canadian pharmacies sell other triamterene and hydrochlorothiazide products instead.
