Is there any harm in children taking montelukast sodium for a long time?

Prolonged use of montelukast sodium in children may lead to neurological side effects such as drowsiness and euphoria, as well as digestive reactions such as nausea and vomiting.
Montelukast Sodium is a non-hormonal anti-inflammatory drug used to treat allergic rhinitis and allergic asthma, and is divided into three categories: granules, chewable tablets, and tablets.
Although the drug is very effective in the treatment of allergic asthma and rhinitis, long-term use of the drug may have some adverse reactions, common neurological and digestive system side effects, such as mental excitement, drowsiness, loss of appetite, nausea and other conditions.
The drug needs to be taken under the guidance of a doctor, and should not be used on its own, so as not to affect the health of children.
