Summary
Montelukast is used to treat asthma, which is a condition causing breathing difficulties, and allergic rhinitis, which is inflammation of the nasal passages due to allergies. It helps reduce symptoms like wheezing, shortness of breath, and runny nose.
Montelukast works by blocking leukotrienes, which are substances in the body that cause allergy and asthma symptoms. By stopping these substances, it reduces inflammation and eases symptoms like wheezing and runny nose.
For adults and teenagers 15 years and older, the usual dose is 10 mg once daily in the evening. For children aged 6 to 14 years, it's typically 5 mg, and for those aged 2 to 5 years, it's usually 4 mg, all taken once daily in the evening.
Common side effects of Montelukast include headache, stomach pain, and sore throat. These effects are generally mild and occur in a small percentage of people taking the medication.
Montelukast may cause mood changes, including agitation, depression, or suicidal thoughts. It can also cause allergic reactions. People with a history of mental health issues should use it with caution. Always consult your doctor about these concerns.
