Micardis contraindications and warnings

Contraindications

Following is information on contraindications to the use of telmisartan in general, pregnancy, breastfeeding and children. Please note that the contraindications may vary depending on the dosage form of a drug (eg tablet, syringe, ointment).

When can Telmisartan not be used?

In case of hypersensitivity to telmisartan the active substance may not be given.

The use of telmisartan is also prohibited in cases of bile dysfunction with obstruction or obstruction of the biliary tract, as well as severe hepatic impairment and severe renal insufficiency. Pregnant women and nursing mothers should also not be treated with telmisartan.

Diabetic patients or patients with impaired renal function who receive the antihypertensive drug aliskiren should not be treated concomitantly with telmisartan.

Relative contraindications to use include constriction of the heart valves (aortic or mitral stenosis), heart muscle disease and thickening (hypertrophic cardiomyopathy), mild or moderate hepatic impairment, pathological changes in the gastrointestinal tract, and active gastric and duodenal ulcers. In these cases, a careful risk-benefit assessment by the attending physician is required.

In primary aldosteronism (impaired hormone secretion of the kidney), the use is generally not recommended. This disease does not respond to AT1 receptor antagonists such as telmisartan.

What should you watch out for during pregnancy and lactation?

Telmisartan should not be used during pregnancy and breast-feeding.

AT1 receptor antagonists, including telmisartan, as well as ACE inhibitors in pregnancy after the formation of the child’s organs can affect their circulation and thus their development. Use in the second and third trimester of pregnancy may therefore cause renal dysfunction, a reduction in the amount of fruit water and slowing of cranial bone growth, and neonatal renal failure, low blood pressure, and excess blood potassium. The intake of ACE inhibitors and AT1 receptor antagonists in the first trimester of pregnancy is not recommended due to lack of data from studies and is expressly prohibited in the period afterwards.

If pregnancy is suspected during pregnancy or pregnancy is planned, telmisartan should be discontinued by the attending physician as soon as possible. This will then decide individually about an alternative treatment.

Since it is not known whether the active substance passes into breast milk, mothers are not allowed to breastfeed during treatment. Therefore, it must be weaned before starting treatment.

What should be considered in children?

Children and adolescents should not receive telmisartan. There is a lack of experience with treatment in this age group.
