Singulair contraindications and warnings


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

When should Montelukast not be used?

In case of hypersensitivity to montelukast, the active substance should not be used.

Pregnant, nursing mothers and children under half a year may take Montelukast only after consultation with the attending physician.

When montelukast is taken with anti-epileptic drugs such as phenytoin or phenobarbital, as well as with rifampicin, an anti-tuberculosis drug, its effects are attenuated by increased hepatic depletion. Here, the use of montelukast (especially in children) should be made only after consultation with the doctor. This should also decide after weighing the benefit and risk, whether an increase in the dose is justified.

What should you watch out for during pregnancy and lactation?

During pregnancy and lactation, montelukast should only be taken after medical consultation, as the safety of an application at this time has not yet been proven.

What should be considered in children?

Children under the age of two should use montelukast only after consulting the attending physician.
