Yes, you can safely take Montair LC (which contains montelukast and levocetirizine) and paracetamol together. There are no known harmful interactions between these medications. Montair LC helps manage allergy symptoms like a runny nose or sneezing, while paracetamol is effective for relieving pain or fever. To keep yourself safe, please ensure you follow the recommended dosages for both. If you feel drowsy, which can sometimes happen with allergy medications, try to rest. If your symptoms persist or worsen, please consult your doctor.
