Micardis Plus: Uses, Side Effects and Dosage

What is MICARDIS PLUS used for?

• MICARDIS PLUS is used in adults to lower high blood pressure.

How does MICARDIS PLUS work?

MICARDIS PLUS contains a combination of 2 drugs, telmisartan and hydrochlorothiazide:

• Telmisartan is an angiotensin receptor blocker (ARB). You can recognize an ARB because its medicinal ingredient ends in “-SARTAN”. It works by blocking a substance in the body that causes blood vessels to tighten. It helps lower blood pressure.
• Hydrochlorothiazide is a diuretic or “water pill” that increases urination. It works by causing the kidneys to get rid of unneeded water and salt from the body into the urine. It also helps lower blood pressure.

This medicine does not cure high blood pressure. It helps to control it. Therefore, it is important to continue taking MICARDIS PLUS regularly even if you feel fine. Do not stop taking your medicine without talking to your healthcare professional.

What are the ingredients in MICARDIS PLUS?

Medicinal ingredients: Telmisartan and hydrochlorothiazide

Non-medicinal ingredients: Iron oxide red (for the 80 mg / 12.5 mg tablet only), iron oxide yellow (for the 80 mg / 25 mg tablet only), lactose monohydrate, magnesium stearate, maize (corn) starch, meglumine, microcrystalline cellulose, povidone, sodium hydroxide, sodium starch glycolate, and sorbitol.

MICARDIS PLUS comes in the following dosage forms:

Tablets: 80 mg / 12.5 mg and 80 mg / 25 mg

Do not use MICARDIS PLUS if:

• you are allergic to telmisartan, hydrochlorothiazide or to any non-medicinal ingredient in MICARDIS PLUS (see What are the ingredients in MICARDIS PLUS?).
• you are allergic to any sulfonamide-derived drugs (sulfa drugs), most of them have a medicinal ingredient that ends in “-MIDE”. This includes other diuretics (“water pills”).
• you have experienced an allergic reaction (angioedema) with swelling of the hands, feet or ankles, face, lips, tongue, throat, or sudden difficulty breathing or swallowing to any ARB (any drug in the same class as MICARDIS PLUS). Be sure to tell your healthcare professional that this has happened to you.
• you have difficulty urinating or produce no urine.

• you are pregnant or planning to become pregnant. Taking MICARDIS PLUS during pregnancy can cause injury and even death to your baby.

• you are breastfeeding. MICARDIS PLUS passes into breast milk.
• you are allergic to some sugars (fructose, lactose and/or sorbitol).
• you have been diagnosed with hereditary fructose intolerance, a rare genetic disorder where you cannot break down fructose. MICARDIS PLUS 80 mg/12.5 mg and 80 mg/25 mg tablets contain 338 mg of a similar type of sugar called sorbitol.
• you are already taking a blood pressure-lowering medicine that contains aliskiren and you have diabetes or kidney problems.

• you have one of the following rare hereditary diseases:

  • Galactose intolerance;
  • Lapp lactase deficiency;
  • Glucose-galactose malabsorption.

This is because lactose is a non-medicinal ingredient in MICARDIS PLUS.

To help avoid side effects and ensure proper use, talk to your healthcare professional before you take MICARDIS PLUS. Talk about any health conditions or problems you may have, including if you:

• have a history of allergic reactions (angioedema).

  • blood pressure lowering medicines, such as aliskiren
  • an angiotensin-converting-enzyme inhibitor (ACEI)
  • beta blockers (i.e., acebutolol, metoprolol). Do NOT stop taking your beta-blocker without talking to your healthcare professional as this can cause serious side effects.
• have lupus, an autoimmune disease that can affect many parts of the body.
• have gout, a type of arthritis.
• are on dialysis.
• are dehydrated or if you suffer from excessive vomiting, diarrhea, or sweating.
• are taking a salt substitute that contains potassium, potassium supplements, or a potassium-sparing diuretic (a specific kind of “water pill” that makes your body keep potassium).

Other warnings you should know about:

Risk of skin cancer:

• MICARDIS PLUS contains hydrochlorothiazide. Treatment with hydrochlorothiazide may increase the risk of developing non-melanoma skin cancer. The risk is higher if you have been taking MICARDIS PLUS for many years (more than 3) or at a high dose.
• While taking MICARDIS PLUS:
• Make sure to regularly check your skin for any new lesions. Check areas that are most exposed to the sun, such as the face, ears, hands, shoulders, upper chest and back.
• Limit your exposure to the sun and to indoor tanning. Always use sunscreen (SPF-30 or higher) and wear protective clothing when going outside.

Talk to your healthcare professional immediately if you become more sensitive to the sun or UV light or if you develop an unexpected skin lesion (such as a lump, bump, sore, or patch) while you are taking MICARDIS PLUS.

Increased sensitivity of the skin to sun: Your skin may become sensitive to the sun while taking MICARDIS PLUS. Limit your exposure to the sun and to indoor tanning. Always use sunscreen (SPF-30 or higher) and wear protective clothing when going outside.

Surgery: Before surgery and general anesthesia (even at the dentist’s office), tell the healthcare professional that you are taking MICARDIS PLUS, as there may be a sudden fall in blood pressure associated with general anesthesia.

Allergic Reactions / Angioedema: Allergic reactions (angioedema) causing swelling of tissues under the skin, sometimes affecting the face and throat, have happened in people taking MICARDIS PLUS. These allergic reactions may happen at any time during treatment with MICARDIS PLUS and can be life threatening. Very rarely, cases have been fatal. If you experience an allergic reaction, stop taking MICARDIS PLUS and get immediate medical help.

Blood Tests: MICARIDS PLUS can cause abnormal blood test results. Your healthcare professional will decide when to perform blood tests and will interpret the results.

Driving and using machines: Before you perform tasks, which may require special attention, wait until you know how you respond to MICARDIS PLUS. Dizziness, lightheadedness, sensation that you, or the environment around you, is moving or spinning (Vertigo) or fainting can occur, especially after the first dose and when the dose is increased.

If patients experience these adverse events, they should avoid potentially hazardous tasks such as driving or operating machinery.

Tell your healthcare professional about all the medicines you take, including any drugs, vitamins, minerals, natural supplements or alternative medicines.
