What Are the Potential Side Effects of Singulair?

Asthma is a relatively common illness, and Singulair can be used to prevent and treat asthma in children. Singulair is suitable for children over one year of age. This medication can prevent the symptoms of asthma during the day and night, improve some adverse symptoms caused by allergic rhinitis, and improve seasonal allergic rhinitis and perennial allergic rhinitis in children aged 2 to 5 years. Before taking the medication, patients should be aware of its side effects. What are the side effects of Singulair? Let's take a look.

Firstly, what are the side effects of Singulair? The main ingredient of Singulair is montelukast sodium, and its side effects are relatively minor. Patients usually have good tolerability, and it is usually not necessary to discontinue treatment after side effects occur. The most common side effects may include abdominal pain and headache. In rare cases, patients may experience hypersensitivity reactions, angioedema, rash, itching, urticaria, abnormal night dreams, drowsiness, irritability, insomnia, nausea, and vomiting. These symptoms can be relieved after discontinuation of the medication.

Additionally, there is currently no research on the safety of Singulair for pregnant and lactating women, so it should be used with caution after weighing the pros and cons. The safety and effectiveness of this medication for children under two years of age have not been reported, so it is generally recommended for children aged 2 to 14 years to use montelukast sodium chewable tablets, and children over 15 years of age can use the same tablets as adults.

Secondly, the main indications of Singulair include the prevention and long-term treatment of asthma in children over one year of age, including the prevention of asthma symptoms during the day and night, the treatment of asthma patients sensitive to aspirin, and the prevention of exercise-induced bronchospasm. It is also indicated for the relief of symptoms caused by allergic rhinitis, including seasonal and perennial allergic rhinitis in children aged 2 to 5 years.

Lastly, the dosage and administration of Singulair are as follows: Take once daily. Asthma patients should take it before bedtime. Patients with allergic rhinitis can take it at the time they need it based on their own situation. Patients with both asthma and allergic rhinitis should take it once a night. Children with asthma aged 1 to 2 years should take one bag once a day. Children with asthma and/or allergic rhinitis aged 2 to 5 years should take one 4mg oral granule bag per day.
