Diovan HCT® Tablets for High Blood Pressure

Diovan HCT® is a prescription combination of valsartan (an ARB) and hydrochlorothiazide (a thiazide diuretic) for adult hypertension. This page explains approved uses, dosing, safety, and access with Canadian pricing. From Canada, it ships to the US with US delivery from Canada, and many compare the Diovan HCT price without insurance before ordering.

What Diovan HCT® Is and How It Works

At CanadianInsulin, orders are filled by licensed Canadian pharmacies after we confirm a valid prescription with your clinic. Diovan HCT® helps lower blood pressure by targeting two pathways. Valsartan blocks angiotensin II receptors to relax blood vessels. Hydrochlorothiazide increases salt and water excretion, which reduces fluid volume. The combination offers additive blood pressure control compared with either ingredient alone. It is used for ongoing control of high blood pressure and is not for sudden spikes or emergencies. We support US shipping from Canada so adults can access therapy reliably after their prescriber’s approval. Many patients also buy valsartan hydrochlorothiazide tablets online after discussing therapy goals and lab monitoring with their clinician.

Who Diovan HCT® Is For

Diovan HCT is indicated for adults with high blood pressure, especially when one medicine alone has not controlled readings. It can also replace separate valsartan and hydrochlorothiazide tablets with a single combination tablet. It is part of comprehensive care for High Blood Pressure alongside lifestyle changes recommended by a clinician.

Do not use during pregnancy. Medicines that act on the renin-angiotensin system can cause injury and death to the developing fetus. Stop as soon as pregnancy is detected and contact a clinician. Diovan HCT is not recommended for children. It is contraindicated in anuria and in anyone with known hypersensitivity to any component or other sulfonamide-derived drugs. Use caution with kidney or liver impairment, volume depletion, low sodium, or gout. People with diabetes should not use aliskiren with an ARB-containing medicine.

Dosage and Usage

Diovan HCT is taken once daily, with or without food, at the same time each day. Swallow tablets whole with water. The specific strength is chosen by your prescriber based on prior therapy and blood pressure targets.

• When switching from either valsartan or hydrochlorothiazide alone, clinicians often select a comparable combination dose and reassess blood pressure.
• When blood pressure is not adequately controlled, the dose may be titrated after one to two weeks, as tolerated.
• The maximum approved daily dose is 320 mg valsartan with 25 mg hydrochlorothiazide (320/25 mg) once daily.

Follow your clinician’s plan for periodic lab testing. Monitoring may include kidney function and electrolytes such as potassium, sodium, and magnesium.

Strengths and Forms

Diovan HCT is supplied as oral tablets in multiple strengths. Availability may vary by pharmacy:

• 80 mg valsartan / 12.5 mg hydrochlorothiazide
• 160 mg valsartan / 12.5 mg hydrochlorothiazide
• 160 mg valsartan / 25 mg hydrochlorothiazide
• 320 mg valsartan / 12.5 mg hydrochlorothiazide
• 320 mg valsartan / 25 mg hydrochlorothiazide

Missed Dose and Timing

If you miss a dose, take it when remembered the same day. If it is close to the next dose, skip the missed dose. Do not take two doses at once. Try to use a daily routine to avoid missed doses. Ask your clinic team if repeated misses occur.

Storage and Travel Basics

Store tablets at room temperature, generally 20 to 25°C (68 to 77°F). Keep them dry, away from excess heat and moisture, and in the original, labeled container. Do not store in a bathroom. Keep out of reach of children and pets.

When traveling, place your medicine in a carry-on bag. Keep it in the original container and bring a copy of the prescription. You can store your order securely at home; for trips, you can pack extra tablets in case of delays. Our shipments use prompt, express shipping from Canada to the US to support continuity of therapy.

Benefits

Lowering blood pressure reduces the risk of stroke and heart attack. Diovan HCT combines two proven approaches in one pill, which may improve convenience and adherence. Once-daily dosing and a range of strengths help clinicians individualize therapy. The valsartan component does not typically cause cough, and hydrochlorothiazide provides additional blood pressure lowering through gentle diuresis.

Side Effects and Safety

• Dizziness or lightheadedness, especially when starting or increasing the dose
• Headache
• Fatigue
• Nausea or stomach upset
• Increased urination
• Muscle cramps
• Photosensitivity or rash
• Electrolyte changes, including potassium, sodium, or magnesium

Serious effects are uncommon but require urgent care: swelling of the face, lips, tongue, or throat (angioedema), severe low blood pressure, severe dehydration, fainting, eye pain or vision changes (rare angle-closure glaucoma with sulfonamides), kidney problems, or severe skin reactions. Diovan HCT must not be used during pregnancy due to fetal toxicity. People with kidney or liver disease need careful monitoring. Tell your clinician about all medicines and supplements before starting.

Drug Interactions and Cautions

• Lithium: increased lithium levels and toxicity risk. Monitoring is required if used together.
• NSAIDs (such as ibuprofen or naproxen): may reduce antihypertensive effect and affect kidney function.
• Potassium supplements, salt substitutes, or potassium-sparing diuretics: risk of high potassium.
• Other blood pressure medicines: additive effects may cause low blood pressure or dizziness.
• Alcohol: can increase dizziness or fainting, especially when starting therapy.
• Cholestyramine or colestipol: may reduce hydrochlorothiazide absorption if taken together.
• Aliskiren: avoid with ARBs in patients with diabetes; use caution in others.

ACE inhibitors may be combined selectively in certain clinical situations, but routine dual renin-angiotensin system blockade is generally avoided. For background on ACE inhibitors, see Ramipril Uses. ARBs may also be used as single agents, such as Losartan, when a diuretic is not needed. Always follow your clinician’s guidance on combinations and monitoring.

What to Expect Over Time

Blood pressure often improves within one to two weeks. The full effect may be seen by about four weeks, depending on dose and prior therapy. Clinicians adjust doses based on measured blood pressure and any side effects. Long-term management often includes home monitoring, lifestyle measures, and periodic labs. If a beta blocker is added for a specific reason, you can learn more in our editorial guide, Bystolic Guide.

Compare With Alternatives

Other approved options include ARB and thiazide combinations such as Hyzaar® (losartan and hydrochlorothiazide) and Micardis Plus® (telmisartan and hydrochlorothiazide). Clinicians may also consider candesartan or telmisartan combinations, or separate single-agent tablets based on your history and lab results. The best choice depends on blood pressure response, tolerability, and coexisting conditions.

Availability and Substitutions

Product availability can vary by strength and package size. If a specific strength is temporarily unavailable, your prescriber may recommend a different strength or an alternative option. One clinically appropriate alternative is tablets containing the same actives listed as valsartan and hydrochlorothiazide; see Valsartan Hct. Your clinic will determine a suitable substitution if needed. Diovan HCT cost from Canada may differ from other listings due to pack size and manufacturer.

Patient Suitability and Cost Saving Tips

Good candidates are adults with hypertension who need more than one agent, can maintain hydration, and can attend periodic lab checks. People who should not use this medicine include pregnant patients, those with anuria, or anyone with known hypersensitivity to components. Use caution with kidney or liver disease and with a history of gout or low sodium.

To manage costs, consider a multi-month supply if your clinician has stabilized the dose. Many patients set refill reminders so therapy is not interrupted. You can store your tablets safely at room temperature. Share new medicines or supplements with your clinic to avoid interactions and unplanned changes in therapy.
