Montelukast (Singulair) is an inexpensive drug used to treat 
asthma. It is also used to treat 
allergies. It is slightly more popular than comparable drugs. It is available in generic and brand versions. Generic montelukast is covered by most Medicare and insurance plans, but some pharmacy coupons or cash prices may be lower.
