SIDE EFFECTS: The most common side effects with montelukast are:
- abdominal pain,
- sore throat, and
- rhinitis (inflammation of the inner lining of the nose).
Other important side effects include:
GENERIC AVAILABLE: Yes
PREPARATIONS: Tablets: 10 mg. Chewable tablets: 4 and 5 mg.
STORAGE: Tablets should be stored at room temperature, 15 C - 30 C (59 F - 86 F).
DOSING: The recommended dose of montelukast in adults is 10 mg daily for treating asthma and allergic rhinitis and 10 mg two hours before exercising for prevention of exercise induced bronchospasm. Montelukast should be taken in the evening with or without food when used for asthma or allergic rhinitis. The 4 and 5 mg tablets are used in children.
PREGNANCY: Montelukast crosses the placenta into the fetus following oral administration to animals, but there have been no adequate studies in pregnant women to determine the effects on the fetus. Physicians may prescribe zafirlukast during pregnancy if it is felt that its benefits outweigh the potential but unknown risks to the fetus.
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.
