Afrin is sold over-the-counter (OTC) decongestant in the form of a nasal spray. Its generic name is oxymetazoline nasal. Afrin is sprayed in the nostrils to give temporary relief from nasal congestion caused by allergies or colds.

This article will go over how Afrin works, some of the common side effects of Afrin, and why using too much Afrin or using it for a long time can lead to rebound congestion.

What Is Afrin Used For?

Afrin is a decongestant medication used to reduce nasal and sinus stuffiness. It’s commonly used to treat congestion from the common cold or allergies.

Being congested can also cause difficulty breathing through your nose while you’re sleeping and may contribute to snoring or sleep apnea. Afrin can help with these symptoms.

How Afrin Works

Afrin comes in a squirt bottle that you can spray into your nostrils. It stimulates receptors in the smooth muscle of the blood vessels in the nose and makes them narrow (constrict). When the blood vessels constrict, it reduces nasal congestion.

You cannot get addicted to Afrin the way you can get addicted to other drugs, but it can stop working if you use it too often, use too much, or use it for a long time.

Rebound congestion from Afrin causes you to have more nasal congestion once the medication wears off.

If Afrin Does Not Work

Afrin is safe and effective when it’s used properly. If your symptoms are not improving after you’ve used Afrin according to the directions, you’ll need to talk to your provider about other treatments.

Serious Reactions to Afrin

It’s less common, but there are also some potentially serious side effects of Afrin that require medical attention, including:

  • Irregular heartbeats (arrhythmias)
  • Chest pain (angina)

For example, if you have chronic nasal congestion, prescription therapy with the use of a nasal corticosteroid can be helpful.

Summary

Afrin is a common decongestant medication used to treat cold and allergy symptoms. It is sold over-the-counter (OTC). While Afrin can be a safe and effective treatment for nasal congestion when it is used according to the directions, overusing Afrin can lead to rebound congestion.

If you have been using Afrin for three days and it hasn’t helped your symptoms, stop using it and let your provider know. You might need a different treatment, like nasal steroids, for your congestion.
