HOW TO USE: Consult your doctor or pharmacist for specific advice on your drug therapy. Do not decrease or stop any asthma medicine unless instructed your doctor. Report promptly to your doctor or pharmacist if your asthma symptoms worsen, short-acting inhaler use increases or use exceeds the prescribed 24 hour maximum. This medicine may come with a patient information leaflet. Read it carefully. Ask your doctor, nurse, or pharmacist any questions that you may have about this medicine.

DRUG INTERACTIONS: Phenobarbital increases the blood concentration of montelukast by about 40%. Rifampin may have the same effect. Therefore, the dose of montelukast may need to be reduced when given concurrently with these drugs.

NURSING MOTHERS: Studies in animals have shown that montelukast is excreted in milk; however, it is not known if montelukast is secreted into breast milk in humans
