Please note: a valid prescription is required for all prescription medication.
Telmisartan HCT is a prescription tablet that combines telmisartan, an angiotensin receptor blocker, with hydrochlorothiazide, a thiazide diuretic. It helps adults with hypertension reach target blood pressure when a single medicine is not enough. Available from Canada with US delivery from Canada and prompt, express, cold-chain shipping.
What Telmisartan HCT Is and How It Works
At CanadianInsulin, orders are filled by licensed Canadian pharmacies after we confirm a valid prescription with your clinic. Telmisartan HCT pairs two time-tested approaches to blood pressure control. Telmisartan selectively blocks angiotensin II type 1 receptors, reducing vasoconstriction and the release of aldosterone. This relaxes arterial tone and lowers systemic resistance. Hydrochlorothiazide reduces sodium and water reabsorption in the distal renal tubule, decreasing plasma volume and helping the heart work more efficiently.
Using two complementary mechanisms can provide greater blood pressure reductions than either alone, especially in patients who have not reached goal on monotherapy. Telmisartan is the same active ingredient found in Micardis, and hydrochlorothiazide is the well-known diuretic in many combination therapies such as Micardis Plus. The hydrochlorothiazide component is described in more detail on our page for Hydrochlorothiazide.
Who Telmisartan HCT Is For
Indications include the management of primary hypertension in adults who would benefit from dual therapy or as a substitution for patients already taking telmisartan and hydrochlorothiazide as separate agents. It is not intended for the initial treatment of severe volume depletion or for acute hypertensive emergencies.
Use should be avoided in pregnancy at any stage because drugs that act directly on the renin-angiotensin system can cause fetal harm. It is not recommended for patients with anuria. Caution is advised in people with severe renal impairment, bilateral renal artery stenosis, hepatic impairment, or those with electrolyte abnormalities. Those with a history of gout may see increased uric acid with hydrochlorothiazide. People with sulfonamide allergy have rarely reported reactions to thiazide diuretics and should be assessed carefully.
For background on the condition, see our pages on Hypertension and High Blood Pressure.
Dosage and Usage
Telmisartan HCT is taken once daily, with or without food, at the same time each day. The combination may be used when single-agent telmisartan or hydrochlorothiazide did not achieve adequate control, or when converting from the two components given separately. Increases are typically made after an appropriate interval to assess response, often within a few weeks.
Swallow tablets whole with water. Consistent daily use is important. Clinicians often check blood pressure at home and in the clinic to guide titration. Lab monitoring can include electrolytes and kidney function, especially after changes in dose or in settings of illness, dehydration, or medication changes.
Strengths and Forms
Film-coated oral tablets are commonly available in the following fixed-dose combinations of telmisartan and hydrochlorothiazide:
- 40 mg / 12.5 mg tablets
- 80 mg / 12.5 mg tablets
- 80 mg / 25 mg tablets
Availability can vary by manufacturer and dispensing pharmacy.
Missed Dose and Timing
If a dose is missed, take it when remembered unless it is close to the time of the next dose. In that case, skip the missed dose. Do not take two doses at the same time. Keeping a daily reminder can help maintain steady control.
Storage and Travel Basics
Store tablets at room temperature, in a dry place, and in the original, child-resistant container. Keep away from moisture and direct heat. During travel, carry your labeled bottle in hand luggage, along with a copy of the prescription if possible. For extended trips, bring extra tablets and a small pill organizer, but keep the main supply in the original container for identification.
Benefits
- Two complementary mechanisms that reduce vascular resistance and fluid load
- Once-daily dosing designed for steady blood pressure control
- Option to substitute for separate components, simplifying the regimen
- May improve adherence by reducing pill burden
- Backed by the clinical experience of ARBs and thiazide diuretics
Side Effects and Safety
- Common: dizziness, lightheadedness, fatigue, increased urination, mild gastrointestinal discomfort
- Electrolyte changes: low sodium, low potassium with hydrochlorothiazide, or elevated potassium with the ARB component in some cases
- Metabolic changes: increased uric acid, slight changes in blood glucose or lipids
- Skin effects: photosensitivity with hydrochlorothiazide
- Less common but serious: symptomatic hypotension, kidney function changes, rare angioedema, severe allergic reactions
Monitor for symptoms of low blood pressure, dehydration, or electrolyte imbalance, particularly during illness, heat exposure, or when other diuretics are used. Rare cases of liver-related issues have been reported with ARBs and require medical attention if jaundice or significant fatigue occurs. Because hydrochlorothiazide is a sulfonamide-derived diuretic, hypersensitivity can occur in susceptible individuals. Drugs in the renin-angiotensin system are contraindicated in pregnancy due to risk of fetal toxicity.
Drug Interactions and Cautions
Potential interactions include the following:
- Other agents affecting the renin-angiotensin system: ACE inhibitors, aliskiren, and additional ARBs can increase the risk of kidney effects and electrolyte changes
- Potassium supplements or potassium-sparing diuretics: raise the risk of hyperkalemia
- Lithium: increased lithium levels and toxicity risk with thiazides
- NSAIDs: may blunt the antihypertensive effect and impact kidney function
- Alcohol and other antihypertensives: additive blood pressure lowering
- Bile acid sequestrants: can reduce hydrochlorothiazide absorption if taken together
People beginning therapy after significant diuretic use or volume depletion can experience symptomatic hypotension. Those with diabetes, gout, or chronic kidney disease often require closer monitoring. As another ARB option used in practice, see Losartan.
What to Expect Over Time
Blood pressure reductions typically build over days to weeks as vascular tone and volume shift to a new steady state. Consistent daily dosing, attention to hydration, and periodic monitoring support long-term control. Many patients continue therapy for the long term as part of a broader plan that can include diet, exercise, and other medicines when appropriate.
Compare With Alternatives
Several combinations provide similar dual-mechanism control. The brand-name pairing of telmisartan with hydrochlorothiazide is available as Micardis Plus. A related ARB plus thiazide option is Candesartan Hctz. Choice among them depends on individual tolerability, response, coexisting conditions, and clinician preference.

Pharmacy teams dispense therapeutically appropriate products in accordance with the prescription and jurisdictional rules.
Patient Suitability and Cost-Saving Tips
Candidates are adults with hypertension who benefit from combination therapy. Those who are pregnant, planning pregnancy, or with anuria should not use agents in this class. Extra caution is appropriate in severe kidney or liver impairment, electrolyte disorders, or a history of gout or sulfonamide allergy.
- Ask about multi-month supplies to reduce copays and dispensing fees
- Set refill reminders so therapy is uninterrupted
- If already on separate components, discuss conversion to a single fixed-dose tablet to simplify the regimen
- Combine orders for household medicines to reduce per-shipment costs
Questions to Ask Your Clinician
- Is Telmisartan HCT an appropriate next step if blood pressure is not at goal on one agent?
- Which starting strength best fits my current readings and medical history?
- How often should electrolytes and kidney function be checked after changes?
- Are there medicines, supplements, or high-potassium foods that should be limited?
- What signs of dehydration or low blood pressure warrant medical review?
- Could a different ARB or another combination be better for my situation?

What is Telmisartan HCT used for?
It is a combination of an angiotensin receptor blocker and a thiazide diuretic used to treat high blood pressure in adults who need dual therapy or substitution for the two components taken separately.
How is Telmisartan HCT different from Micardis Plus?
Both contain telmisartan and hydrochlorothiazide. Micardis Plus is a brand-name version, while Telmisartan HCT is a generic. Your clinician can determine whether brand or generic is appropriate.
How should Telmisartan HCT be taken?
Tablets are taken once daily at the same time each day, with or without food. Titration and monitoring are guided by clinical response, lab results, and tolerability according to labeling.
What are common side effects?
Dizziness, fatigue, increased urination, photosensitivity, and mild gastrointestinal symptoms are common. Electrolyte changes, low blood pressure, and kidney function changes can occur and require monitoring.
Is Telmisartan HCT safe in pregnancy or breastfeeding?
Drugs acting on the renin-angiotensin system can cause fetal harm and are contraindicated in pregnancy. Use during breastfeeding is generally not recommended because hydrochlorothiazide can appear in breast milk.
Can I switch from separate tablets to this combination?
Yes, when clinically appropriate. Many patients transition from individual telmisartan and hydrochlorothiazide tablets to a single fixed-dose combination to simplify therapy under clinician direction.
How long does it take to work?
Blood pressure improvements are often observed within days, with fuller effect over the next few weeks as vascular tone and fluid balance reach a new steady state.
