Micardis (telmisartan) tablets

Micardis is a prescription medicine (telmisartan) used to treat high blood pressure and, in some adults, to reduce cardiovascular risk. This page explains how it works, dosing basics, safety points, and storage so refill planning is simpler. Ships from Canada to US for cash-pay access, including for people without insurance.

What Micardis Is and How It Works

Telmisartan belongs to a class called angiotensin II receptor blockers (ARBs). Angiotensin II is a hormone in the renin-angiotensin-aldosterone system (RAAS, a hormone pathway that affects blood pressure and fluid balance). By blocking angiotensin II at the AT1 receptor, the drug relaxes blood vessels and can reduce aldosterone-driven salt and water retention. The overall effect is lower blood pressure and less strain on the heart and arteries.

This treatment is used long term, and blood pressure response can vary between patients. Regular monitoring and follow-up with a prescriber are part of standard care, especially when other cardiac or kidney conditions are present. Licensed Canadian pharmacies dispense medications after required documentation is reviewed.

Who It’s For

This medicine is commonly prescribed for adults with hypertension (high blood pressure). Some patients may also receive it to reduce the risk of cardiovascular events when they have established cardiovascular disease or multiple risk factors and cannot use certain other therapies, depending on local labeling. For a broader view of condition-focused options, the Hypertension Overview hub lists related therapies that may be prescribed.

Contraindications and “do not use” situations are based on labeling and clinical context. ARBs are not used during pregnancy because drugs that act on the RAAS can harm a developing fetus. Caution is also used in people with severe dehydration, significant kidney artery narrowing, or a history of serious allergic reactions to similar agents. Patients with diabetes may be advised to avoid combining an ARB with aliskiren. A prescriber should evaluate comorbidities, current medications, and recent lab results before starting or continuing therapy.

Dosage and Usage

Micardis tablets are taken by mouth, typically once daily. They can be taken with or without food, but taking doses consistently (same general time each day) helps support steady blood levels and clearer home blood pressure logs. If a dose is missed, labeling commonly advises taking it when remembered unless it is close to the next scheduled dose; doses are not doubled.

Typical dosing framework

For adult hypertension, prescribing commonly starts with a once-daily dose and adjusts based on response and tolerability. In many product labels, 40 mg once daily is a typical starting point, and some patients may be titrated to 80 mg once daily if additional blood pressure lowering is needed. Dose selection can differ when other conditions are present, such as volume depletion from diuretics or reduced kidney function, because these factors can increase the chance of symptomatic hypotension (feeling faint). Any change in dose should be directed by a prescriber, with follow-up blood pressure readings and, when appropriate, lab monitoring.

Why it matters: Consistent dosing supports safer interpretation of home blood pressure trends.

Patients using multiple cardiovascular drugs may benefit from medication-list reviews before refills. For related blood pressure education, the Atenolol Hypertension Guide explains how another class is typically used and monitored.

Strengths and Forms

This product is supplied as an oral tablet. Two common strengths are 40 mg and 80 mg; availability can vary by pharmacy and country source. In practice, prescribers may choose a strength that supports the intended daily dose and simplifies adherence.

Some markets also carry combination products that pair telmisartan with a thiazide diuretic (a “water pill”), often referred to as telmisartan/hydrochlorothiazide combinations. These combinations are sometimes described using brand variants such as Micardis HCT or Micardis Plus, but specific presentations depend on the approved product and dispensing source.

Storage and Travel Basics

Store tablets at room temperature in a dry place, protected from excess moisture and heat. Keep the medication in its original packaging until use when possible, since manufacturer packaging is designed to limit humidity exposure. If the tablets are supplied in a blister pack, avoid opening cavities ahead of time. Check the label for any temperature ranges or special handling instructions specific to the dispensed product.

When traveling, keep medicines in carry-on luggage to reduce exposure to extreme temperatures in checked bags. Patients who cross time zones may want to keep a simple dosing log and confirm timing with their prescriber if schedules change substantially. It can also help to keep a current medication list with dose and indication for emergency care. For additional cardiovascular reading, the Cardiovascular Articles collection compiles practical guides on common therapies.

Quick tip: Keep tablets away from bathroom humidity and kitchen steam.

Side Effects and Safety

Like other ARBs, this therapy can cause side effects related to blood pressure lowering and changes in electrolytes. Commonly reported effects include dizziness, lightheadedness, fatigue, or gastrointestinal upset. Symptoms are more likely when starting therapy, after dose increases, or when a patient is dehydrated from vomiting, diarrhea, heavy sweating, or diuretic use. Standing up slowly and keeping clinically appropriate hydration can reduce the chance of falls related to low blood pressure.

More serious risks include symptomatic hypotension (fainting), hyperkalemia (high potassium), and changes in kidney function, particularly in patients with chronic kidney disease, heart failure, or those using other RAAS-active drugs. Signs that warrant urgent evaluation can include swelling of the face or throat, trouble breathing, severe weakness, confusion, or chest pain. Because fetal harm is a known risk with RAAS drugs, pregnancy avoidance and prompt clinician contact after suspected pregnancy are standard label precautions. When needed, prescription details are confirmed with the prescriber before dispensing.

Many clinicians monitor blood pressure and periodic labs such as serum creatinine and potassium after initiation and after dose adjustments. For context on managing overlapping metabolic and cardiovascular risks, see Diabetes And Hypertension Practices and Heart Health With Diabetes.

Drug Interactions and Cautions

Interactions can increase side effects or change how well blood pressure is controlled. Combining an ARB with other drugs that affect the RAAS (such as ACE inhibitors or aliskiren) can raise the risk of kidney injury, hyperkalemia, and hypotension; some combinations are avoided in specific populations, including people with diabetes taking aliskiren. Potassium supplements and potassium-based salt substitutes can also increase potassium levels, so clinicians often review diet and supplements when starting therapy.

Nonsteroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen or naproxen can reduce the blood-pressure-lowering effect and may increase kidney risk, especially when combined with diuretics. Lithium levels may rise when used with RAAS-active drugs, which can be clinically significant. Alcohol can add to dizziness in some patients. For background on ACE inhibitors and monitoring considerations, the Altace Blood Pressure Guide and SGLT2 Inhibitors And Heart Failure offer complementary discussion points to review with a clinician.

Compare With Alternatives

Within the ARB class, commonly prescribed options include telmisartan, losartan, valsartan, irbesartan, and candesartan. Selection may depend on prior response, comorbid conditions, dosing preferences, and formulary availability. Some patients also use an ACE inhibitor instead of an ARB, or a calcium channel blocker, depending on clinical goals and side-effect history. Combination therapy (for example, pairing an ARB with a thiazide diuretic) is also common in hypertension care when single-drug therapy is insufficient.

Micardis is a branded form of telmisartan; some prescriptions specify brand while others allow substitution based on local rules. For related product references, see Telmisartan and Losartan. Comparisons should focus on label indications, patient-specific risks, and monitoring needs rather than assuming one option is “better” overall.

Pricing and Access

Pricing can vary based on strength, quantity, and whether a brand or Micardis generic (telmisartan) is dispensed. Packaging format and country-sourced presentation can also affect overall costs. Patients paying cash, including those without insurance, often compare options by total tablet count and refills authorized, then confirm the exact dispensed product with the pharmacy.

The service supports cash-pay access for patients who lack insurance. For cross-border fulfillment, US shipping from Canada is available where permitted and with a valid prescription. Current non-time-limited offers, when available, are listed on Promotions.
