How does Singulair work?
Blocks leukotrienes, inflammatory chemicals released in asthma and allergic rhinitis that tighten the airways and cause swelling and mucus. Unlike a reliever inhaler this works preventively over time, not during an attack.
How to take Singulair
Usually one tablet in the evening, taken every day whether or not you have symptoms. It is a preventer, not a rescue medicine — keep using your reliever inhaler for sudden breathlessness.
Always follow the dose printed on your pack or given by your prescriber — it can differ from the general guidance above.
