Cough with Nasal Congestion

Common causes for nasal congestion

Whether you’re delivering an important client presentation or calming down the after-school chaos, nasal congestion is not your friend. One minute your nose is running like a broken tap, then the next you can barely breathe through your blocked nostrils. Wait – here comes that pesky cough to add to your misery! So, what is nasal congestion that can sometimes be accompanied by a cough. 

First, let’s review what normally goes on inside your nose. Your nasal passages and the surrounding air-filled cavities (called sinuses) contain lots of blood vessels. Nerves send signals to these blood vessels to control how much blood they contain, which then regulates the airflow through your nasal passages by keeping them open wide. Your nasal passages and sinuses also produce mucus to help filter out irritants from the air you breathe in.

When you have nasal congestion, inflammation causes these blood vessels to widen, making your nasal passages swell up and block the airflow. You can get nasal congestion for a bunch of different reasons, but the most common cause is a viral infection of your upper airways such as the common cold or flu. Nasal congestion can also be a symptom of allergies such as hay fever or exposure to irritants in the air, such as dust or smoke.

But how can having a blocked or runny nose make you cough? Firstly, the inflammation in your airways caused by an upper respiratory tract infection can make your cough reflex extra sensitive, triggering a dry cough. Secondly, these infections also cause your nose and sinuses to go into overdrive with mucus production. This excess mucus can further block up your already swollen nasal passages, making your nasal congestion worse, but it can also drip down the back of your throat, triggering your cough reflex.

Treatment options for nasal congestion

The good news when you’re feeling all blocked and stuffy? Viral infections of your upper airways, such as the common cold, usually clear on their own in about 7 to 10 days. But there are different treatment options available to help relieve your symptoms and help you feel less congested. Look for products that contain decongestants such as phenylephrine – decongestants work to narrow the blood vessels in your nasal passages to reduce the swelling whilst helping to relieve nasal congestion.

And even better news? When your nasal congestion comes with a cough, DURO-TUSS^® has you covered.

DURO-TUSS PE Chesty Cough Liquid Plus Nasal Decongestant combines the mucolytic bromhexine hydrochloride with phenylephrine – to help relieve a chesty cough and relieve a blocked or runny nose.

Home remedies for nasal congestion

This one might sound a little strange, but another top tip to help reduce nasal congestion is to rinse your nose out with salty water. The fancy term is ‘saline irrigation’ – take a very mild saline solution (available at your pharmacy) and gently flush it through your nose and sinuses. This can help get rid of excess mucus and any irritants in your nasal passages, reducing your stuffiness whilst helping you feel more comfortable

When to see a medical professional

Nasal congestion and coughs that come with cold and flu typically resolve on their own in a couple of weeks. Remember to always speak with your doctor if you have any concerns about any of your symptoms. You should seek medical advice if:

• Your symptoms get worse or last longer than 10 days
• You develop a fever
• You experience lots of thick nasal discharge, sinus pain, or other facial pain
• Common symptoms of COVID-19 are like those found with illnesses such as a common cold and flu.  If you develop cold and flu symptoms get tested immediately, stay at home and call Healthline on 0800 358 5453 for advice.
