Dosages Available

Singulair is a prescription drug used to treat airway constriction and inflammation associated with conditions like chronic asthma, as well as indoor and outdoor allergies. The drug works by targeting chemicals called leukotrienes, which respond to irritants in the throat by tightening the airway. While this process normally expels the irritants, individuals with asthma or other respiration problems are left with labored breathing and may even suffer an acute asthma attack.

Singulair comes in several standard doses with just one of these intended for adult patients. However, a doctor may wish to increase or decrease a patient’s dosage slightly based on factors such as the patient’s age, health condition and existing medication regimen. Singulair is always taken orally.

Singulair 10 mg Pill

The 10 mg pill is the standard dosage of Singulair for adults. It is supplied as a beige, square shaped tablet with rounded edges. The pill is also covered in a protective film. The name Singulair is printed on one side of the pill, with MRK 117 embossed on the other.

Singulair 4 mg and 5 mg Chewable Tablet

The Singulair 4 mg and 5 mg chewable tablet is a lower strength version of the adult dose typically given to patients between the ages of two and 14. It is supplied as a rounded, pink-colored tablet. On one side of the tablet is printed the name Singulair, with either MRK 711 or MRK 275 appearing on the other. Which code is printed depends on whether the chewable tablet is 4 mg or 5 mg.

Singulair 4 mg Granules

The 4 mg Singulair granules are the chosen form of the drug for patients between the ages of 12 month and two years. This dosage is supplied as a child-proof packet made of foil. Inside is a substance consisting of 500 mg granules of solid Singulair. The granules can either be taken directly or mixed with food, breast milk or baby formula.

Taking Singulair

Individuals with asthma should take Singulair once daily, preferably in the evening in order to combat nighttime asthma attacks. Those taking the drug for allergies must also take the drug every day, but may do so at any time. Patients taking Singulair for exercise induced bronchoconstriction should take the drug about two hours prior to engaging in physical activity.
