Step 4: Read and complete the decision guide to learn more about your symptoms.
Your cough is likely the result of irritating mucus or irritants in your throat or nose.
Most people who have these symptoms can relieve their persistent cough by using a combination antihistamine-decongestant medicine, because this can diminish allergy symptoms and reduce nasal mucus production. A prescription nasal spray containing a corticosteroid is another treatment that may help, and some people benefit from using the oral medicine montelukast (Singulair).
Contact your doctor if your cough does not completely resolve with over-the-counter antihistamine-decongestant products.
