Telmisartan (Micardis®) for Hypertension

Telmisartan is a prescription angiotensin II receptor blocker used to treat high blood pressure and to reduce certain cardiovascular risks in adults. At CanadianInsulin, orders are filled by licensed Canadian pharmacies after we confirm a valid prescription with your clinic. Your medicine ships from Canada to the US with Canadian pricing, which may help if you pay without insurance. Telmisartan is the active ingredient in Micardis®.

What Telmisartan Is and How It Works

Telmisartan blocks angiotensin II at its receptor. This relaxes blood vessels, lowers vascular resistance, and helps the heart work more efficiently. Lowering blood pressure reduces the risk of stroke, heart attack, and kidney complications over time.

Beyond hypertension, telmisartan is approved to reduce the risk of heart attack, stroke, or death from cardiovascular causes in certain high-risk adults who are unable to take an ACE inhibitor. It is not a beta blocker or a diuretic. It can be used alone or combined with other blood pressure medicines when additional control is needed.

Who Telmisartan Is For

Telmisartan is indicated for adults with hypertension. It is also indicated to reduce cardiovascular risk in adults at high risk who cannot use an ACE inhibitor. People taking it often have other risk factors such as diabetes, prior coronary disease, or smoking history. For blood pressure treatment plans that need a diuretic, your prescriber may consider a telmisartan and hydrochlorothiazide option such as Telmisartan Hct.

Some adults should avoid telmisartan. Do not use during pregnancy. Avoid with aliskiren in patients with diabetes. People with severe liver problems, bilateral renal artery stenosis, or a history of angioedema need careful evaluation. Pediatric use is not established.

Dosage and Usage

Follow your prescriber’s instructions on how to take telmisartan. Typical adult dosing for hypertension starts at 40 mg once daily. Some patients may start at 20 mg once daily, especially if volume-depleted. The usual maintenance range is 20 mg to 80 mg once daily. Many patients take telmisartan 40 mg; others may require 80 mg for full effect. Take it at the same time each day, with or without food.

For cardiovascular risk reduction, the recommended dose is 80 mg once daily, as supported by labeling. If you are starting therapy for risk reduction, your prescriber may monitor blood pressure and kidney function during titration.

Do not split or crush tablets unless your clinician advises it. If your plan requires a fixed-dose combination, your prescriber may consider a formulation that includes a thiazide diuretic. Some patients may also review branded combinations like Micardis® Plus when appropriate.

Strengths and Forms

Telmisartan is supplied as oral tablets. Common strengths include:

• 20 mg tablets
• 40 mg tablets
• 80 mg tablets

Availability may vary by pharmacy and lot. Packaging and imprint can differ by manufacturer.

Missed Dose and Timing

If you miss a dose, take it when you remember on the same day. If it is near the time for your next dose, skip the missed dose and resume your regular schedule. Do not take two doses at once.

Storage and Travel Basics

Store your tablets at room temperature, typically 20 to 25°C (68 to 77°F). Keep them dry, in the original container, and away from excess heat and moisture. When you travel, carry your medicine in your hand luggage with the prescription label attached. Do not leave tablets in a hot car. Keep out of reach of children and pets.

Benefits

Telmisartan offers once-daily dosing and sustained 24-hour blood pressure control in many patients. Lowering blood pressure helps protect the brain, heart, and kidneys. For eligible high-risk adults who cannot tolerate an ACE inhibitor, telmisartan reduces the risk of major cardiovascular events per approved labeling. Many patients appreciate that it does not usually cause the dry cough associated with ACE inhibitors.

Side Effects and Safety

• Dizziness or lightheadedness, especially when standing up
• Fatigue
• Back pain or muscle aches
• Sinus congestion
• Diarrhea or abdominal discomfort
• Upper respiratory symptoms
• Low blood pressure in volume-depleted states

Serious but less common risks include high potassium, kidney function changes, and rare angioedema. Telmisartan carries a boxed warning for fetal toxicity. Do not use during pregnancy. If pregnancy is detected, contact your clinician promptly to discontinue. People with severe liver disease or renal artery stenosis need special caution and monitoring.

Drug Interactions and Cautions

Key interactions and cautions include:

• Aliskiren: Avoid combination in patients with diabetes.
• ACE inhibitors: Dual renin-angiotensin system blockade increases adverse effects and is generally not recommended.
• Potassium-sparing diuretics, potassium supplements, or salt substitutes: Increased risk of hyperkalemia.
• NSAIDs: May reduce the antihypertensive effect and worsen kidney function, especially in older adults or those who are dehydrated.
• Lithium: Risk of elevated lithium levels and toxicity; monitor if co-administered.
• Diuretics: Starting telmisartan while on a diuretic can cause low blood pressure; prescribers may correct volume depletion first.
• Digoxin: Concentrations can increase; monitoring may be needed in some cases.

Discuss all prescription drugs, OTC pain relievers, and supplements with your healthcare professional to avoid interactions. For background on related therapies, see Bystolic Helps and Ramipril Uses.

What to Expect Over Time

Blood pressure often improves within 1 to 2 weeks of starting telmisartan. Full effect may take up to 4 weeks at a given dose. For cardiovascular risk reduction, benefits depend on long-term, consistent use along with lifestyle measures and control of other risk factors. Your prescriber will decide if and when to adjust the dose based on response and tolerability.

Compare With Alternatives

Several approved antihypertensive options are commonly considered. Micardis® contains the same active ingredient as telmisartan in a branded form and may be preferred in some care plans. Another ARB option is Cozaar® (losartan), which is also taken once daily for many patients. In cases where a diuretic is needed, clinicians sometimes consider ARB-thiazide combinations. The choice depends on medical history, response, and tolerability.

Patient Suitability and Cost Saving Tips

Telmisartan suits many adults with hypertension who need once-daily therapy. It is not appropriate during pregnancy or for people with known hypersensitivity to telmisartan. People with significant liver disease, advanced kidney impairment, or low blood pressure should be evaluated carefully.

Cost-saving ideas include:

• Asking your prescriber about a 90-day supply to reduce per-tablet cost.
• Keeping the dose stable to limit partial fills and changes.
• Coordinating refills so you maintain continuity and avoid urgent local fills.
• Comparing the cost of telmisartan 40 mg versus 80 mg when appropriate.
• Reviewing whether a combination option like Telmisartan Hct suits your plan if a diuretic is needed.

Questions to Ask Your Clinician

• Is telmisartan 40 mg the right starting dose for my blood pressure?
• When should I consider adjusting to 80 mg once daily?
• Could I benefit from adding a thiazide diuretic or a calcium channel blocker?
• How will we monitor kidney function and potassium while I take this medicine?
• What should I do if I feel dizzy or lightheaded after a dose?
• Are there lifestyle changes that can enhance my blood pressure control?
• Which OTC pain relievers are safer with my blood pressure plan?
