What should you know about Singulair allergy medicine?

Singulair contains montelukast, a leukotriene receptor antagonist. It blocks chemical signals involved in airway and nasal inflammation. A clinician may consider it when allergic rhinitis occurs with asthma or when other options are unsuitable. It is not an antihistamine and does not give rapid relief for a severe allergic reaction. Symptoms such as a blocked nose, runny nose, itchy eyes or itchy throat can have different triggers, including house dust mites or pets. The right treatment depends on the pattern, severity and other conditions.

Take it exactly as prescribed and do not use another person's tablets. Do not use it to manage sudden breathing difficulty. Tell the prescriber about other medicines, liver problems, pregnancy, and any history of depression, anxiety or sleep disturbance. Watch for new nightmares, agitation, mood changes, unusual thoughts or suicidal thinking, and contact a clinician promptly if they occur; seek emergency help if there is immediate danger. Continue practical trigger control, such as reducing exposure to known allergens, alongside the agreed plan.

Seek emergency help for swelling of the lips or tongue, severe wheezing, faintness or trouble breathing. Contact a clinician promptly if allergy symptoms remain uncontrolled, sleep is repeatedly disrupted, or mental or behavioural changes appear after starting or changing Singulair. A worsening cough or chest tightness may indicate asthma needs review rather than an extra allergy tablet.

Ask why Singulair is being considered, how long to try it, what improvement to look for, and which alternative treatments may fit. Ask how to handle a missed dose and whom to contact about mood, sleep or behaviour changes.
