How to Stop a Sinus Cough

Chronic cough is a condition caused by postnasal drip from your sinuses, excess mucus that trickles down the back of your throat and causes irritation. Relief from sinus cough can be achieved by treating your sinus infection--the source of your excessive coughing. Treatment for sinus infections includes antibiotics, over-the-counter medications such as antihistamines and decongestants, and home remedies.

Is This an Emergency?

If you are experiencing serious medical symptoms, seek emergency treatment immediately.

See a specialist. Your doctor or allergy specialist can prescribe oral antibiotics to treat the infection. Commonly prescribed antibiotics include penicillin, cephalosporins and macrolides, according to Alan R. Hirsch, author of "What Your Doctor May Not Tell You About Sinusitis." Medication should be taken until the prescription runs out to completely destroy the infection and prevent infection resistance 1.

Foods That Irritate the Sinuses

Purchase over-the-counter medications. OTC antihistamines and decongestants can alleviate sinus cough by reducing congestion caused by sinus inflammation. As the swollen tissues decrease in size, mucus can be easily excreted. Antihistamines block allergens from attaching to your histamine receptor sites by coating the sites, while decongestants work by constricting blood vessels to reduce swelling. Follow package directions for proper dosage.

Flush your sinuses. A bulbed syringe can be purchased at most drug stores, and provides sinus cough relief by using warm water to flush mucus from your sinuses. This type of treatment requires regular flushing in order to maintain clear sinuses. Squeeze the bulb syringe in a small bowl of warm water to pick up the water, then gently squeeze it into each nostril. Be sure to have your head over the bowl to catch the mucus and water.

Prop up your pillows at night. While sleeping, your head should be propped up to avoid postnasal drip that causes night coughing.

Eliminate mucus-causing foods from your diet. Caffeine, sugary desserts, chocolate, dairy products and fried, fatty foods can increase mucus production and make your sinus cough worse. Limit your daily consumption or try restricting them from your diet until chronic coughing subsides.


Side effects of antibiotics include dizziness, nausea, vomiting, diarrhea, constipation, skin rashes or headache. Contact your doctor if side effects occur for longer than three days.
