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.
Who Should Not Use Afrin
Some people should not use Afrin, including
Children younger than 6 years oldPeople who are pregnantPeople who have taken an antidepressant called a monoamine oxidase inhibitor (MOAI) within the last 14 days
If you have these health conditions, talk to your provider before you use Afrin:
High blood pressure Heart disease Hyperthyroidism Diabetes mellitus Enlarged prostate Glaucoma
Afrin can also interact with OTC and prescription medications and supplements. You should tell your provider about all the medications you take and ask if it’s safe to take Afrin with them.
Afrin Side Effects
Afrin can cause side effects. Most of them are not serious and will go away as soon as you stop using the medication.
Common side effects of Afrin include:
Nose dryness and irritation Sneezing Dizziness High blood pressure Fast heart rate Heart palpitations Restlessness Trouble falling or staying asleep
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.
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.
