What are decongestants?

Decongestants are medications designed to relieve nasal congestion, which often occurs due to colds, allergies, or sinus infections.

They work by narrowing the blood vessels in the nose, reducing swelling and congestion, and helping to clear the nasal passages. This action reduces the amount of mucus and makes breathing easier.

Decongestants are available in various forms, including tablets, nasal sprays, and liquids. Common active ingredients found in these medications include pseudoephedrine, found in tablets, and phenylephrine, which is often used in nasal sprays.

While effective for short-term relief, it’s important to use these medications as directed to avoid side effects like rebound congestion, where symptoms can return worse than before if the medication is used for too long.

Conditions treated by decongestants

Decongestants are primarily used to relieve nasal congestion and other symptoms associated with various respiratory ailments. These conditions include:

• Common cold and flu: Decongestants help alleviate the nasal stuffiness that typically accompanies these viral infections, making it easier to breathe and helping reduce the discomfort associated with a blocked nose.
• Allergic rhinitis (hay fever): For individuals suffering from allergic reactions to pollen, dust, pets, or other environmental allergens, decongestants can provide relief from nasal congestion and improve airflow.
• Sinusitis: Whether acute or chronic, sinusitis often results in significant nasal congestion due to inflammation of the sinuses. Decongestants help reduce this swelling and facilitate the drainage of mucus, which can alleviate pain and pressure in the sinus areas​.
• Ear infections: While not a direct treatment for the infection, decongestants can help ease the discomfort and pressure associated with ear infections, particularly those affecting the middle ear, by improving Eustachian tube function​.
• Other respiratory conditions: Decongestants may also be used in the management of other respiratory conditions that cause nasal blockage or congestion, such as bronchitis or respiratory syncytial virus (RSV), to help improve breathing.

How do decongestants work?

Decongestants alleviate nasal congestion primarily by causing vasoconstriction, which is the narrowing of blood vessels in the nasal passages. This reduction in blood vessel size leads to decreased swelling and inflammation, resulting in a clearer airway and easier breathing.

The active ingredients in most decongestants, such as pseudoephedrine and phenylephrine, target the receptors on blood vessels in the nasal mucosa. When these receptors are activated, they cause the muscles around the blood vessels to contract, thereby narrowing the vessels (vasoconstriction).

This process not only reduces the blood flow but also diminishes the overall volume of the nasal tissues, leading to a decrease in congestion.

Here’s a closer look at how this process helps in different situations:

• Immediate relief: Nasal sprays and drops containing decongestants provide quick relief by acting directly on the nasal mucosa, reducing swelling and opening up the nasal passages almost immediately.
• Sustained effects: Oral decongestants may take longer to work but provide a more prolonged effect as they are absorbed into the bloodstream and distributed throughout the body.

It’s important to use decongestants according to the directions provided, especially nasal sprays, which can lead to rebound congestion if used for more than a few days consecutively. This phenomenon, known as rhinitis medicamentosa, occurs when the nasal passages swell up again and become more congested than before once the medication is stopped​.

Common decongestants

Some of the most commonly used decongestants include:

• Pseudoephedrine: This is one of the most effective oral decongestants and is available behind the pharmacy counter in many countries due to regulations concerning its use. It provides significant relief from nasal and sinus congestion but can cause side effects such as increased heart rate and blood pressure.
• Phenylephrine: Available over-the-counter, phenylephrine is used in many oral medications as well as nasal sprays. It is generally considered less effective than pseudoephedrine for relieving nasal congestion when taken orally, but it is useful for those who may not tolerate pseudoephedrine well​.
• Oxymetazoline: Found in nasal sprays, oxymetazoline is effective for short-term relief of nasal congestion. It acts quickly to shrink swollen nasal mucosa but should not be used for more than three consecutive days to avoid rebound congestion, a condition where nasal passages become more congested once the medication is stopped.
• Xylometazoline: Similar to oxymetazoline, xylometazoline is used in nasal sprays to reduce the swelling of the nasal passages, facilitating easier breathing. It is also subject to the same caution regarding the duration of use due to the risk of rebound congestion.
