How Allercet M Syrup works

Levocetirizine is an H1-antihistamine that blocks histamine to relieve sneezing, itching and runny nose. Montelukast is a leukotriene receptor antagonist that reduces airway/allergic inflammation and helps prevent wheeze and nasal symptoms.

How to take Allercet M Syrup

Oral syrup; take the measured dose using a measuring cup/spoon, usually once daily (often in the evening) or as prescribed. Can be taken with or without food; shake well before use.

Take it exactly as your doctor prescribed. Do not change the dose or stop early on your own.

Missed dose and overdose

If you miss a dose

Take the missed dose of Allercet M as soon as you remember. If it is almost time for the next dose, skip the missed one and carry on with the usual schedule. Do not take two doses together to make up for a missed dose.

If you take too much

Taking more Allercet M than prescribed can be harmful. If you suspect an overdose, contact a doctor or go to the nearest emergency department at once, and carry the pack or strip with you. In India the emergency number is 112.

Habit formingNo

Warnings and precautions

May cause drowsiness—avoid driving/alcohol if affected. Use with caution in kidney disease (levocetirizine dose adjustment may be needed). Montelukast has been associated with mood/behavior changes (agitation, sleep disturbances, depression, suicidal thoughts); stop and seek medical help if these occur. Not for sudden acute asthma attack; keep rescue inhaler as advised. Use in children only as per age-appropriate dose prescribed.

Interactions with other medicines

Alcohol and other CNS depressants (increased drowsiness), sedating antihistamines, other leukotriene antagonists (duplicate therapy). Rifampicin/phenobarbital/phenytoin may reduce montelukast effect. Theophylline may lower montelukast levels slightly.
