Leukotriene receptor antagonist
What to do if you miss a dose of Montelukast
Missing a dose of Montelukast (Montelukast) is common — most people will skip a dose at some point during a course. The right action depends on how long since the missed dose and whether Montelukast is taken event-driven or daily at 4mg, 5mg, 10mg. The wrong action — doubling up — is not recommended.
For daily Montelukast
If Montelukast is taken daily for a chronic condition, take the missed dose as soon as you remember, unless it is almost time for the next scheduled dose. In that case skip the missed dose and continue normally. According to the prescribing information for Montelukast, two doses should never be taken close together to "make up" for a miss.
For event-driven Montelukast
If Montelukast is used as needed (not on a fixed schedule), there is no "missed dose" in the conventional sense — simply take the planned dose when needed and observe the recommended gap before re-dosing. Montelukast selectively blocks the CysLT1 receptor, which mediates the action of leukotrienes C4, D4 and E4 — proinflammatory mediators released by mast cells and eosinophils in the airway.
Frequently asked questions
Should I double the dose if I missed Montelukast? ▾
No. Doubling doses of Montelukast to compensate is not recommended at any 4mg, 5mg, 10mg strength and increases the risk of side effects without improving efficacy. Take the next scheduled dose normally.
How many missed doses are too many? ▾
Occasional missed doses of Montelukast are usually inconsequential. Repeated missed doses can compromise the therapeutic effect — for chronic conditions like those treated with Leukotriene receptor antagonist, consistent dosing matters. If adherence is hard, discuss reminders, simpler schedules or alternative formulations with the prescriber.
