Montelukast Dosing

Montelukast dosing guidelines take certain factors into account, such as a person's age and if other medications are being taken. When treating nasal allergies, the dose can range from 4 mg to 10 mg. To prevent exercise-induced asthma, the recommended dose for adults and adolescents age 15 and older is montelukast 10 mg, taken two hours before exercise.

 

An Introduction to Montelukast Dosing

The dose of montelukast sodium (Singulair®) that your healthcare provider recommends will vary, depending on a number of factors, including:
 
  • Your age
  • Other medical conditions you may have
  • Other medications you may be taking.
     
As is always the case, do not adjust your montelukast dose unless your healthcare provider specifically instructs you to do so.
 

Montelukast Dosing for Asthma or Allergies

The recommended montelukast dose for adults and adolescents age 15 and older is montelukast 10 mg a day. For children ages 6 to 14 years old, the recommended dose is montelukast 5 mg, taken once daily. For young children ages two to five years old, the recommended dose is montelukast 4 mg (either as a chewable tablet or packet of oral granules), taken once daily. For children age 6 to 23 months old, the recommended dose is one packet of montelukast oral granules (4 mg), taken once daily.
 
When treating asthma, it is generally best to take montelukast in the evening to prevent nighttime asthma symptoms. To prevent exercise-induced asthma, the recommended dose for adults and adolescents age 15 and older is montelukast 10 mg, taken two hours before exercise. The medication should not be taken more frequently than every 24 hours, and should not be taken before exercise if you are already taking it once a day.
