Montelukast is a medication commonly used to manage and prevent asthma symptoms and relieve seasonal allergies. It works by blocking leukotrienes, which are chemicals in the body that cause inflammation, bronchoconstriction, and mucus production in the airways. This helps to improve breathing and reduce the frequency of asthma attacks. Typically taken as a daily oral tablet, Montelukast is suitable for both adults and children. It is important to follow a healthcare provider's instructions regarding dosage and usage. While it is effective for many, some individuals may experience side effects, so monitoring for any unusual reactions is essential.
