Micardis
4 customer reviewsMicardis is a telmisartan tablet for adults with high blood pressure. It is used for long-term blood pressure control and, in selected patients, to help lower cardiovascular risk. It works by blocking angiotensin II so blood vessels relax and pressure falls.
What is it?
Micardis is a blood-pressure medicine containing telmisartan, used for adults with arterial hypertension. It is taken as oral tablets for long-term control, not for sudden emergency BP drops. Telmisartan relaxes blood vessels by blocking angiotensin II, helping reduce strain on the heart and lowering cardiovascular risk.
Composition
Micardis contains the active ingredient telmisartan.
Telmisartan belongs to the angiotensin II receptor blocker (ARB) class. ARBs are a standard option in hypertension guidelines and are widely used because they lower blood pressure without the dry cough that some people experience with ACE inhibitors. Telmisartan has also been assessed in large cardiovascular-outcomes studies, which is one reason clinicians may choose it when risk is higher [1].
Combination products that add hydrochlorothiazide (a thiazide diuretic) exist in some markets and may be prescribed when one medicine alone does not lower blood pressure enough. In practice, the “plus a diuretic” step is often chosen when salt sensitivity, fluid retention, or resistant hypertension is suspected, because hydrochlorothiazide increases sodium and water excretion.
How to use?
Micardis is used to treat high blood pressure in adults and to lower the risk of cardiovascular events in people who need long-term blood pressure control. It helps relax blood vessels so the heart can pump against less resistance, which can reduce strain on the cardiovascular system.
How does it work?
- Take Micardis 40 mg by mouth once daily as an oral tablet.
- Swallow the tablet whole with water.
- Take it with or without food.
- If needed, the dose may be increased to 80 mg once daily.
- In some patients, treatment may start at 20 mg once daily.
- Use it for long-term treatment unless your prescriber tells you to stop or change the dose.
Indications
Micardis is a brand of telmisartan used to treat high blood pressure (hypertension). By improving day-to-day blood pressure control, it can also be used in selected patients to reduce the risk of cardiovascular events such as stroke or heart attack, when a clinician judges the overall risk to be high.
High blood pressure often has no symptoms. Many people only notice it when complications start.
Micardis is designed for steady, consistent control across the day rather than a rapid “rescue” effect. This matters if you tend to see higher readings in the early morning or late evening, when missed doses show up quickly.
Comparison
Micardis is telmisartan alone. Micardis Plus refers to telmisartan + hydrochlorothiazide, combining an ARB with a thiazide diuretic.
Clinicians typically start with a single agent when blood pressure is mildly to moderately elevated, then add a second mechanism if targets are not reached. The combination approach can produce a stronger BP reduction because it tackles both vascular tone (telmisartan) and fluid/sodium balance (hydrochlorothiazide). The trade-off is tolerability: adding a diuretic can increase urination, affect sodium levels, and raise uric acid in predisposed patients.

Contraindications
Micardis is not for you if any of the following apply:
- Allergy or hypersensitivity to telmisartan
- Pregnancy (especially second and third trimester)
- Breastfeeding when safer alternatives are available
- Severe liver impairment, including cholestasis or biliary cirrhosis
- Age under 18 years (safety and efficacy are not established)
- Existing severe hyperkalaemia
Not recommended for
Micardis needs extra care in a few common scenarios.
If you use diuretics, have been fasting, or recently had significant sweating, the first doses can lower pressure more than expected. This is a classic “first-week wobble” people describe, and it is preventable with sensible titration.
Side effects
Micardis is often well tolerated, yet side effects can still occur, especially early on or after dose changes. The most common day-to-day issues are dizziness, headache, and sometimes tiredness, usually linked to the blood pressure lowering itself rather than an allergy to the medicine.
Common and expected effects
- Dizziness or light-headedness, more likely during the first days of treatment or after dose increases
- Headache
- Mild gastrointestinal symptoms such as nausea or diarrhoea
One sentence that matters: stand up slowly.
Less common but clinically important
- Hypotension (too-low blood pressure), more likely with dehydration or concurrent diuretics
- Hyperkalaemia (high potassium), which may show up as weakness, tingling, or palpitations
- Changes in kidney function, usually in people with kidney artery narrowing, advanced kidney disease, or combined RAAS blockade
Rare reactions needing urgent assessment
- Angioedema (swelling of face/lips/tongue, breathing difficulty)
- Severe allergic rash
If a combination with hydrochlorothiazide is used, extra side effects can include increased urination, low sodium, gout flares, and photosensitivity. EMA safety information for telmisartan and related ARBs highlights monitoring of renal function and electrolytes in at-risk groups, which aligns with routine hypertension care pathways [3].
Common mistakes
Most problems I see are avoidable and come from routine habits.
- Stopping once readings look better. Blood pressure can climb back quietly, and the person only discovers it at the next clinic visit.
- Taking it “as needed.” Micardis is built for daily control; intermittent dosing leads to roller-coaster readings.
- Starting right after a hot day with poor hydration. Low fluid volume raises the chance of light-headedness or fainting in the first week.
- Using potassium salt substitutes freely. Some salt substitutes are potassium-based and can push potassium too high when combined with an ARB.
- Doubling a dose after a missed tablet. This can cause an unnecessary BP drop.
Doctor opinions
In day-to-day prescribing, doctors often choose telmisartan when they want 24-hour coverage with once-daily dosing and a low rate of cough compared with ACE inhibitors. Many patients tolerate ARBs well, yet early dizziness can happen if the starting dose is too high for the person’s baseline, or if they are also on a diuretic.
A pattern clinicians recognise: people who “feel fine” sometimes stop antihypertensives after a few weeks because the home BP readings improved. The readings improve because the medicine is working; stopping often brings the numbers back up within days to weeks, and the long-term risk returns with it. WHO cardiovascular prevention materials keep stressing sustained BP control as a core risk-reduction strategy, since the harm of hypertension is cumulative over years [2].
