MONTISIS-L by Chemisis Pharmaceuticals is a combination medication containing Levocetirizine and Montelukast, designed to treat allergic rhinitis and asthma. This combination works by targeting different pathways in the body to provide comprehensive relief from allergy and asthma symptoms.

• Levocetirizine (5 mg): An antihistamine that blocks H1 receptors, reducing the effects of histamine in the body. This helps to relieve allergy symptoms such as runny nose, sneezing, itching, and watery eyes.
• Montelukast (10 mg): A leukotriene receptor antagonist that blocks the action of leukotrienes, which are chemicals in the body that cause inflammation, bronchoconstriction, and mucus production. Montelukast helps to prevent asthma attacks and control allergy symptoms.

The typical dosage of MONTISIS-L is one tablet taken once daily in the evening, with or without food. It is important to take this medication regularly to achieve the best results, especially for long-term conditions like asthma. Common side effects of this combination medication may include headache, dizziness, drowsiness, and gastrointestinal issues such as nausea and abdominal pain. Serious side effects are rare but can include mood changes, severe allergic reactions, and liver problems. Patients should inform their healthcare provider if they experience any unusual or severe symptoms.
