In asthma, Singulair 4mg relaxes the air passages of the lungs to make breathing easier and to help prevent asthma attacks. You should continue to take your Singulair even if you feel that your asthma is under control.
Singulair will not relieve your symptoms once an attack of breathlessness or an asthma attack has started. You must use your fast-acting inhaled bronchodilator to relieve an asthma attack. Ask your prescriber or asthmanurse for advice on what to do if you have an asthma attack.
Singulair also reduces your body’s response to allergens and to certain situations which trigger asthma attacks. In this way it can help prevent asthma which is triggered by exercise. In people with asthma it can also help relieve the symptoms of seasonal allergic rhinitis.
You need to take Singulair as prescribed in order to get the best results from using it. It is a good idea to make it part of your routine and to take it at the same time or times every day. The pharmacy label will tell you how much you should take.
