Taking montelukast with other medicines and herbal supplements (2024)

Cautions with other medicines

There are some medicines that may affect how montelukast works.

Tell your doctor or pharmacist if you're taking any of these medicines:

• epilepsy medicines such as phenobarbital or phenytoin
• rifampicin, for tuberculosis and some other infections
• gemfibrozil, for high cholesterol

It's usually safe to take everyday painkillers with montelukast. However, do not take non-steroidal anti-inflammatory drugs (NSAIDs) such as aspirin or ibuprofen if they've ever made your asthma symptoms worse.

Mixing montelukast with herbal remedies and supplements

There's not enough information to say that complementary medicines and herbal remedies are safe to take with montelukast. They're not tested in the same way as pharmacy and prescription medicines. They're generally not tested for the effect they have on other medicines.
