13 Oct 2021 by Trân Trương

With a medically advanced background, you have many options for effective and fast dry cough treatment.

Unusual irritation in the throat can cause you to have an uncontrollable dry cough. Sometimes, the cough persists, causing extreme discomfort. However, because this is a common health symptom, people are often subjective, letting the cough go away on its own instead of seeking treatment.

In some cases, this subjectivity carries a high risk of serious health damage, especially if the dry cough is caused by COVID-19.

1. What is the cause of a dry cough?

Before looking into treatments, you should know why you have a dry cough.

In most cases, a dry cough is caused by a viral infection. You may experience this symptom frequently in people who have a cold or flu.

In addition, a dry cough is sometimes associated with a number of other health conditions, such as:


In people with asthma, the airways swell and become narrow, causing not only a dry cough, but also difficulty breathing or wheezing.

1.2.Gastroesophageal reflux disease (GERD)

Acidic stomach acid backing up into the esophagus can damage this organ. At that time, the patient often has a cough reflex.

1.3. Postnasal drip syndrome

When the glands in the nose and throat secrete too much mucus, the fluid can run down and accumulate in the back of the throat, causing an itchy throat, triggering a cough to occur.


Sometimes a dry cough is also a sign that an allergic reaction is going on, especially in people who are sensitive to certain elements in the air (smoke, pollen, pet dander, etc.).

1.5.Side effects of drugs

According to statistics, about 20% of people have signs of persistent dry cough when using certain ACE inhibitors, such as enalapril (Vasotec) or lisinopril (Prinivil, Zestril) …

1.6.Whooping cough

This is a form of respiratory infection, characterized by a dry cough and a hoarse voice when breathing.

1.7.Cough due to Covid-19 infection

The acute respiratory infection COVID-19 broke out in December 2019 in China and is currently a global pandemic. This is an infectious disease caused by the SARS-CoV-2 virus, which has the ability to infect a large area with high speed. Patients tend to have a dry cough and show no signs of improvement when taking conventional cough medicine. In addition, some other symptoms of COVID-19 can be mentioned such as high fever, chest tightness, shortness of breath, body aches…

2. Effective treatment of dry cough

A persistent dry cough can be extremely uncomfortable. However, do not worry too much because you have many options for fixing this problem, such as:

How to treat dry cough with medicine

The drugs below are OTC (over-the-counter) and can be purchased at pharmacies nationwide. Common cough medicines include:

2.1.Drugs for stuffy nose

When a cold occurs, the lining of the patient’s nose often swells, obstructing the flow of air. Decongestants can correct this condition by narrowing the capillaries in the nose, thereby reducing blood flow to swollen tissues.

If the swelling of the mucous membranes goes away, breathing will return easily. At the same time, decongestants also work to overcome the situation where mucus flows down and accumulates in the back of the throat, causing a dry cough.

2.2.Cough suppressants and expectorants

Antitussives (cough suppressants) work to calm a cough by blocking factors that irritate the throat. Most people with dry cough symptoms trust this group of drugs. They are especially useful if a dry cough causes a sore throat or interferes with sleep.

In addition, expectorants work to thin the mucus that accumulates in the back of the throat, thereby reducing irritation of the cough.

3. Tips to cure dry cough at home

If you don’t want to depend too much on medicine, you can also treat a dry cough with some of these folk tips:

  • Gargle with salt water
  • Drink a lot of warm water, be careful not to drink cold water
  • Eat liquid foods such as soups, porridges, soups, etc.
  • Drink honey
  • Stay away from irritants (pollen, pet dander, etc.)

4. Treat dry cough caused by COVID-19

The dry cough caused by the COVID-19 epidemic cannot be treated with conventional methods. At this point, what you need to do is carefully observe the abnormal manifestations of the body, and at the same time isolate yourself to avoid spreading the virus to everyone around. In addition, in order to prevent the disease from getting worse leading to complications, you should quickly seek medical help from the authorities and hospitals with Covid-19 treatment facilities or local medical facilities. .
