Triazide® Tablets and Capsules for Hypertension and Edema

Triazide is a prescription diuretic that combines triamterene with hydrochlorothiazide. It treats hypertension and helps reduce edema. This page explains how the medicine works, who it suits, and how to access it with US delivery from Canada, including options for triamterene HCTZ without insurance.

What Triazide Is and How It Works

Triazide® is a fixed-dose combination of a potassium-sparing diuretic and a thiazide diuretic. Hydrochlorothiazide helps your kidneys remove extra sodium and water. Triamterene helps the body hold onto potassium, which can reduce the risk of low potassium that may occur with thiazides alone.

YouDrugstore is a licensed Canadian pharmacy in Manitoba. Pharmacists review prescriptions before dispensing.

This combination may help control blood pressure and swelling caused by certain conditions. The blend can be useful when a clinician wants the fluid-reducing effect of a thiazide while limiting potassium loss. Triazide generic triamterene hydrochlorothiazide provides the same active ingredients as the brand in many markets.

Because it acts on kidney salt handling, effects can vary with diet, other medicines, and kidney function. Your healthcare professional may check blood tests to follow electrolytes and renal function during treatment.

Who It’s For

This medicine is used in adults for hypertension and for edema related to conditions where a diuretic is appropriate. It is not a first step for every person with high blood pressure; your clinician may choose it when two actions are desired in one pill or when potassium tends to run low on a thiazide.

People with high potassium, severe kidney disease, or inability to pass urine should not take this treatment. Avoid salt substitutes containing potassium unless your prescriber approves them. Discuss use if you are pregnant or breastfeeding, as the prescriber will weigh risks and benefits. Tell your clinician about sulfonamide allergies, a history of kidney stones, gout, liver disease, or diabetes.

Dosage and Usage

Use exactly as prescribed by your clinician. Many adults take the dose once daily, often in the morning, to limit nighttime urination. Some regimens use a divided schedule. Taking with food or milk can help with stomach upset. Swallow capsules or tablets whole with water.

Limit alcohol and rise slowly from sitting to reduce dizziness. Do not use potassium supplements, high-potassium salt substitutes, or other potassium-sparing diuretics unless your prescriber tells you to do so. Your care team may advise periodic checks of potassium, sodium, kidney function, and uric acid.

Keep a log of blood pressure readings at home if asked. Bring the record to appointments. For lifestyle tips that support medical therapy, see our article Caduet Medication and our Cardiovascular section.

Strengths and Forms

This combination comes as capsules and tablets in several fixed strengths. Availability can vary by manufacturer and market.

• Triazide 37.5/25 mg capsules
• Tablets containing triamterene with hydrochlorothiazide in commonly published strengths

Not all strengths or presentations may be in stock at all times. Your prescription will specify the exact strength and form suitable for you.

Missed Dose and Timing

If you miss a dose and it is close to the time for your next dose, skip the missed dose and take the next dose on schedule. Do not double up. Because this is a diuretic, taking it earlier in the day may help reduce nighttime trips to the bathroom. Follow the plan your prescriber gives you.

Storage and Travel Basics

Store at room temperature in a dry place, away from moisture and out of reach of children and pets. Keep it in the original bottle with the pharmacy label. Do not store it in the bathroom. When traveling, keep your medicine in carry-on luggage along with a copy of your prescription and your prescriber’s contact details. Use a simple reminder system to help you take it as directed when changing time zones.

Dispose of unused tablets or capsules through a pharmacy take-back program if available. Do not flush medicines unless the label specifically instructs you to do so.

Benefits

This treatment combines two complementary actions in one daily pill. The thiazide component helps remove excess fluid and lower blood pressure. The potassium-sparing component can help maintain potassium levels. A single prescription product may simplify therapy compared with taking two separate diuretics.

For some people, the combination can support blood pressure goals alongside diet, exercise, and other prescribed agents. The therapy may also help reduce edema where a diuretic is indicated and appropriate.

Side Effects and Safety

• Increased urination
• Dizziness or lightheadedness
• Headache
• Nausea or stomach upset
• Dry mouth or thirst
• Muscle cramps
• Sun sensitivity

Serious effects can include high potassium, low sodium, kidney changes, severe rash, or dehydration. Gout flares can occur in susceptible people. Seek urgent care for fainting, significant weakness, labored breathing, irregular heartbeat, or signs of severe allergic reaction. This medicine may interact with diabetes therapy and can affect lab tests; your prescriber may advise monitoring.

Drug Interactions and Cautions

Tell your clinician about all medicines, vitamins, and herbal products you use. Important interactions may include:

• ACE inhibitors or ARBs, which can raise potassium
• Other potassium-sparing diuretics or potassium supplements
• NSAIDs, which can affect kidney function and the diuretic effect
• Lithium, due to risk of increased levels
• Other antihypertensives; additive blood pressure lowering can occur
• Corticosteroids or ACTH, which may affect electrolytes

Avoid high-potassium salt substitutes unless your prescriber approves them. Limit excessive sun exposure and use sunscreen due to potential photosensitivity from the thiazide component.

What to Expect Over Time

Blood pressure control typically requires consistent daily use plus lifestyle support. You may notice more frequent urination after starting or changing the dose. As your body adjusts, your clinician may review your readings and labs and decide whether to continue, adjust, or pair this therapy with other agents. Keep a steady routine, take doses at the same time each day, and stay hydrated as advised by your prescriber.

Compare With Alternatives

Possible alternatives include thiazide diuretics alone, such as hydrochlorothiazide or chlorthalidone, when potassium retention is not a concern. In other cases, clinicians may choose agents from different classes, such as ACE inhibitors, ARBs, beta blockers, or calcium channel blockers. Combination products can also be options for people who need more than one mechanism.

Some adults manage blood pressure with a calcium channel blocker and statin combination when appropriate; see Caduet for one such option discussed by your prescriber.

Availability and Substitutions

Supply can vary by strength and manufacturer. If a specific capsule or tablet is unavailable, your prescriber may recommend an equivalent generic or another diuretic class backed by your medical history. We cannot promise restock dates. Your care team decides whether a substitution is suitable for you.

Patient Suitability and Cost-Saving Tips

Good candidates are adults with high blood pressure or edema who would benefit from a thiazide plus potassium-sparing action. It may not suit people with high potassium, severe kidney impairment, or those taking certain interacting medicines. Older adults and those with liver or kidney concerns may require closer monitoring.

To manage costs, consider multi-month supplies if your prescription allows, and set refill reminders to prevent lapses. Discuss generic options with your prescriber if appropriate. Use your home blood pressure readings to help your clinician optimize your plan.
