How Grilinctus Syrup works

This medicine is a combination product. One ingredient blocks histamine to reduce allergy symptoms like runny nose and itching. Another ingredient acts on the brain's cough center to reduce the urge to cough, especially dry cough. A decongestant ingredient narrows blood vessels in the nose to ease congestion. Depending on the specific product, other ingredients may loosen and thin mucus to make cough more productive.
