Disclaimer: This page provides general information about Micardis (telmisartan). It is intended to support conversations with your healthcare professional.

What is Micardis?

Micardis is the brand name for telmisartan, a medicine in the class known as angiotensin II receptor blockers (ARBs). It is used to help lower high blood pressure and may be prescribed for other heart-related conditions under medical supervision. In Australia, whether a prescription is required can depend on local regulations and the specific medical indication.

Telmisartan works by blocking a natural chemical in the body that narrows blood vessels. By preventing this narrowing, the blood vessels relax and widen, which helps to lower blood pressure and improve blood flow. Micardis can be used alone or together with other medicines prescribed for cardiovascular conditions.

The medicine is typically taken as a tablet and is usually prescribed to be taken once daily. Take Micardis exactly as directed by your clinician, and do not alter the dose without professional advice. If you have trouble swallowing tablets, talk to your pharmacist about possible alternatives or directions from your doctor.

This information is intended as a general guide. It is not a substitute for personalised medical advice. If you have questions about whether Micardis is right for you, discuss this with your doctor or pharmacist, and refer to the official product information for Micardis.

What is Micardis used for?

The primary use of Micardis is to treat hypertension (high blood pressure). Lowering blood pressure reduces the risk of heart disease and stroke in many adults, when used as part of a broader treatment plan that may include lifestyle changes. Your clinician will determine whether Micardis is appropriate for your blood pressure target and overall health goals.

Micardis may also be prescribed as part of a treatment plan for other cardiovascular conditions as determined by a doctor. In some cases, a clinician may combine it with other medicines to achieve better control of your condition. The exact indications will depend on individual health status and guideline recommendations.

In addition to hypertension, Micardis may be used for other approved indications in adults under medical supervision. It is important to follow the prescribing clinician’s instructions and to discuss any other treatments you are taking. If you are unsure of the reason Micardis was prescribed for you, ask your doctor to explain its specific role in your care plan.

Check the official leaflet and your pharmacist’s advice for a complete list of indications and any cautions. Some uses may be more suitable for certain patients after assessment of kidney function, liver function, and other health factors. The information here is not a substitute for professional guidance.

How Micardis works

Telmisartan works by blocking the angiotensin II type 1 (AT1) receptor. When this receptor is blocked, the blood vessels relax and widen, which lowers resistance in the circulatory system. This results in a reduction in blood pressure and a more efficient flow of blood around the body.

The action of Micardis also reduces the release of certain hormones that can cause the body to retain salt and water. By limiting this effect, the medicine can help decrease fluid buildup in some patients and contribute to improved cardiovascular function. The overall effect is improved blood flow and reduced workload on the heart.

It is important to note that Micardis is not a quick fix for blood pressure. The full therapeutic effect may take days to weeks to become evident, and the response can vary between individuals. Ongoing treatment is typically required, with regular review by a clinician to ensure the target blood pressure and safety are maintained.

As with many medicines for chronic conditions, Micardis works best as part of a comprehensive care plan that includes healthy lifestyle choices, such as regular physical activity, balanced nutrition, and smoking cessation where applicable. Your clinician may adjust the plan over time based on how you respond to therapy and changes in your health status.

How to use Micardis

Your doctor will tell you how to take Micardis, including how many tablets to take and when to take them. In general, tablets are swallowed whole with a glass of water and can be taken with or without food. Do not crush, chew, or split the tablets unless your doctor specifically instructs you to do so.

Take Micardis at roughly the same time each day to help you remember. If you miss a dose, take it as soon as you remember unless it is almost time for your next dose. Do not take a double dose to make up for a missed one; if you are unsure what to do, contact your pharmacist or doctor for guidance.

Avoid stopping Micardis suddenly without medical advice. If you are considering stopping the medication due to side effects or feeling unwell, talk to your clinician first so they can provide safe guidance. If you are starting or stopping other medicines, inform your doctor, as some combinations may require monitoring or dose adjustments.

Store Micardis in a cool, dry place away from direct sunlight and out of reach of children. Do not use medicines that are past their expiry date. If you have any questions about how to use Micardis, ask your pharmacist for clear instructions tailored to your situation.

Who should avoid Micardis

Micardis should not be used by individuals with a known allergy to telmisartan or to any component of the medicine. If you have ever experienced an allergic reaction to this medication or similar drugs, you should avoid taking it and discuss alternatives with your clinician.

People who are pregnant or planning to become pregnant should avoid Micardis. Telmisartan can harm a developing fetus, and stopping the medicine should be discussed with a healthcare professional. If pregnancy occurs while taking Micardis, seek medical advice promptly.

Severe liver disease or significant kidney problems may require special considerations when using Micardis. A clinician will assess kidney and liver function, and may adjust treatment or choose an alternative therapy based on your health status and laboratory results.

Concomitant use with certain medicines, such as some other blood pressure drugs or potassium-related therapies, may require careful monitoring. Always inform your doctor about all medicines you are taking, including over-the-counter drugs and complementary products. Adjustments may be needed to keep you safe and effective treatment ongoing.

Warnings

In some people, Micardis can cause angioedema, a swelling of the face, lips, tongue, or throat that can be serious and require urgent medical attention. Seek immediate help if you notice swelling, especially of the tongue or lips, or trouble breathing. This risk is rare but important to recognise.

Micardis may affect kidney function, particularly in people who have dehydration, low blood pressure, or pre-existing kidney problems. Your clinician may monitor kidney function with tests and adjust treatment if needed. If you experience reduced urination, swelling, or unusual fatigue, contact your healthcare professional promptly.

Hyperkalemia, an elevated level of potassium in the blood, can occur with Micardis, especially in people taking other medicines that raise potassium or with kidney impairment. Your clinician may check potassium levels and advise on diet and supplements to avoid high potassium foods or supplements without professional guidance.

Nonsteroidal anti-inflammatory drugs (NSAIDs) and some other medications can interact with Micardis, potentially affecting blood pressure or kidney function. If you routinely take NSAIDs for pain or other conditions, discuss this with your clinician to determine a safe approach to their use while on Micardis.

Side effects

Like all medicines, Micardis can cause side effects, although not everyone will experience them. Some people may notice symptoms early after starting treatment, while others may not have any noticeable effects initially. Your clinician will balance benefits and possible adverse effects when deciding on therapy.

Common side effects reported with Telmisartan include dizziness or lightheadedness, especially after a first dose or when your dose is increased. Fatigue, upper respiratory infections, and mild nausea may also occur in some people. These side effects are usually manageable and may improve as your body adjusts to the medicine.

Less commonly, Micardis can cause back pain, stomach upset, or joint pain. If you experience persistent or worrying symptoms, discuss them with your doctor to determine whether the medication is the cause and whether any change in treatment is needed.

Serious but rare side effects require immediate medical attention. Seek urgent help if you notice symptoms such as swelling of the face or throat, severe dizziness with fainting, persistent cough, or signs of an allergic reaction. Your clinician will provide guidance on what to do if you notice any of these symptoms.

Interactions

Before starting Micardis, tell your doctor about all medicines you take, including prescription drugs, over-the-counter products, and any supplements. Some drug interactions can affect the safety or effectiveness of Micardis or other medicines you are taking concurrently.

Medicines that can interact with Micardis include other antihypertensive drugs, potassium-sparing diuretics, and potassium supplements. Using these together may raise the risk of high potassium levels or excessive lowering of blood pressure, so your clinician may adjust doses or monitor more closely.

Nonsteroidal anti-inflammatory drugs (NSAIDs), especially when used for a prolonged period, can affect kidney function and blood pressure control in some people taking Micardis. If you regularly use NSAIDs for pain or inflammation, discuss a plan with your doctor to minimise potential risks while still addressing your symptoms.

There are interactions with certain medicines used to treat diabetes, heart rhythm problems, or other cardiovascular conditions. Always inform your healthcare provider about all your medicines to help prevent adverse interactions and ensure safe treatment planning.

Pregnancy

Micardis should not be used during pregnancy unless specifically advised by a clinician. Telmisartan can pose risk to the developing fetus, particularly when used in the second and third trimesters. If you think you may be pregnant, or if you become pregnant while taking Micardis, contact your doctor promptly for advice.

If you are planning a pregnancy, discuss contraception and potential medication options with your healthcare professional. In many cases, alternative therapies may be considered during pregnancy to protect both mother and baby. Do not stop therapy without professional guidance, as this can also carry risks.

During breastfeeding, you should talk to your clinician about the safest option for you and your baby. Some medicines pass into breast milk, and your doctor can help you weigh benefits and risks before continuing or stopping treatment.

If you are a woman of childbearing potential taking Micardis, ensure that you have regular medical reviews and pregnancy planning conversations with your healthcare team. This helps to ensure the safest possible approach for your health.

Frequently asked questions

How long does Micardis take to lower blood pressure?

Your clinician will monitor your blood pressure over time and may adjust treatment to achieve the target range. If you have concerns about how quickly you are responding, discuss them with your doctor.

Initial effects may be noticed soon after starting therapy, but peak benefits often occur after a period of continued use. Do not adjust the dose without medical advice, even if you do not feel different immediately.

In addition to medicine, lifestyle changes such as reducing salt intake, maintaining a healthy weight, and regular physical activity can help support blood pressure management. Your doctor can provide a plan tailored to you.

What should I do if I miss a dose?

If you miss a dose, take it as soon as you remember, unless it is near the time for your next dose. In that case, skip the missed dose and resume your regular schedule. Do not double up to make up for a missed dose without talking to your clinician.

If you are unsure what to do after missing a dose, contact your pharmacist or doctor for guidance. They can advise on the safest course of action based on your current treatment plan.

Keeping a routine can help prevent missed doses. Consider using reminders on your phone or a pillbox if helpful. Always follow the advice given by your healthcare team for the best results.

Can Micardis be taken with other blood pressure medicines?

Micardis is sometimes prescribed together with other blood pressure medicines under medical supervision. Your clinician will consider your overall cardiovascular risk and may adjust treatments to achieve better control. Regular monitoring is often needed when combining therapies.

Never add or stop another blood pressure medication without first consulting your doctor. Some combinations can lower blood pressure too much or interact in unexpected ways.

If you experience dizziness, fainting, or extreme fatigue after starting a new combination therapy, contact your clinician promptly. They can assess whether the regimen is appropriate for you and make adjustments if required.

Is it safe to drink alcohol while taking Micardis?

Alcohol can interact with blood pressure medicines by further lowering blood pressure and increasing dizziness in some people. If you drink alcohol, do so in moderation and discuss any concerns with your doctor. They can advise on safe levels for your situation.

If you notice unusual dizziness or lightheadedness after consuming alcohol while on Micardis, consider reducing intake or avoiding alcohol and seek medical guidance if symptoms persist.

Your clinician can provide personalised recommendations based on your health status and other medications. It is important to balance social or lifestyle choices with treatment goals.

Can Micardis cause dizziness or fainting?

Dizziness is a common side effect, especially after the first dose or after a dose increase. Standing up too quickly can worsen this feeling. To reduce risk, rise slowly from a sitting or lying position and avoid driving if you feel unsteady.

If dizziness continues or interferes with daily activities, talk to your doctor. They may adjust the dose or suggest additional management strategies to improve comfort and safety.

Let your clinician know about any other medicines you take that could contribute to dizziness, as some drug interactions can increase this effect.

Is there a risk of high potassium with Micardis?

Hyperkalemia, or high potassium levels, can occur with Micardis in some people, particularly if you have kidney problems or are taking certain other medicines or supplements. Higher potassium levels can be dangerous for heart rhythm and other functions.

Your clinician may monitor your potassium level with blood tests, especially when starting treatment or changing other medicines. If you notice symptoms such as muscle weakness, unusual fatigue, or numbness, inform your doctor promptly.

Do not start potassium supplements or salt substitutes that contain potassium without medical advice, as this could increase the risk of high potassium while taking Micardis.

Should I stop Micardis if I develop a persistent cough?

A persistent cough is more commonly associated with some other blood pressure medications, such as ACE inhibitors. ARBs like Micardis typically have a lower risk of this effect, but if a cough develops or worsens, discuss it with your clinician. Do not stop taking Micardis without medical advice.

Your doctor can determine whether the cough is related to the medicine or to another cause, and they can suggest appropriate steps. In some cases, an alternative therapy may be considered if the cough is bothersome or persistent.

Reporting persistent respiratory symptoms to your healthcare provider helps ensure safe and effective management of your condition. A professional can guide whether a change in treatment is warranted.

Is Micardis safe during pregnancy?

Micardis is generally avoided during pregnancy because of potential risks to the fetus. If you are planning pregnancy or become pregnant while taking this medicine, contact your clinician promptly for guidance. They can discuss alternatives and ensure you have a suitable plan.

Contraception should be discussed with your healthcare provider if you are of childbearing potential and taking Micardis. Regular medical review helps ensure an appropriate and safe treatment approach during reproductive years.

If pregnancy occurs, seek urgent medical advice. Do not discontinue therapy abruptly without professional guidance, as your clinician can provide the safest course of action for you and your baby.

What should I tell my doctor before starting Micardis?

Share a complete list of all medicines you currently use, including over‑the‑counter drugs and supplements. Certain medicines can interact with Micardis or affect how well it works, so your clinician can plan an appropriate treatment strategy.

Inform your doctor about any history of kidney or liver disease, electrolyte imbalances, or pregnancy plans. Your clinician may need to adjust the treatment or monitor certain health parameters more closely.

Discuss any known allergies and your overall health status, including blood pressure trends and heart-related symptoms. Honest and thorough communication helps ensure a safer therapy approach tailored to you.

How should I store Micardis?

Store Micardis tablets at room temperature, away from excess heat and moisture, and out of reach of children. Do not keep medicines in the bathroom or near a kitchen sink where humidity can cause degradation.
