Afrin is a decongestant that helps relieve a blocked, stuffy nose.
It can be used to alleviate the symptoms of several conditions like nasal infections, offering temporary relief in as little as 5 to 10 minutes.
Afrin may not treat the infection itself; you might need antibiotics for that. You can use it alongside antibiotics, so while the antibiotics fight the infection, Afrin helps relieve the symptoms.
How does Afrin work?
Oxymetazoline, the active ingredient in Afrin, is a nasal decongestant. It’s part of a class of drugs called alpha-1 agonists, which works by narrowing the blood vessels in the nose. This helps reduce swelling and congestion, alleviating symptoms like stuffy and blocked nose.
Afrin can’t treat the infection, you might need antibiotics for that if the infection is severe.
What doses of Afrin are there?
Afrin comes in one dose of 0.05%. You’ll typically use it twice a day for a few days. Avoid using it for more than seven days as you might experience side effects.

How to use Afrin
You’ll need to prime the bottle before using Afrin. To prime it, shake the bottle gently and press the pump a few times until a fine mist is produced. Now your Afrin bottle is ready to use.
To use Afrin:
Remove the cap.
Hold the bottle upright.
Place the nozzle at the tip of your nostril.
Hold the other nostril closed.
Press the pump twice as you breathe in.
Repeat for the other nostril.
How long does Afrin take to work?
Afrin works quickly, providing relief in just 5 to 10 minutes and lasts for 12 hours. It can be used twice daily for a full day of easy breathing. If your symptoms don’t improve or worsen, let your physician know.
I made a mistake using Afrin, now what?
If you use more than the recommended amount, it’s unlikely to cause any side effects. But you should avoid using it for more than seven days, even if your symptoms don’t improve. Using it for long periods can cause something known as ‘the rebound effect’, which is when your symptoms return after improving with the medication.

Afrin: FAQ
Have something specific you want to know? Search our info below, or ask our experts a question if you can’t find what you’re looking for.
How does Afrin compare with Flonase?
Answer:
Afrin (oxymetazoline hydrochloride) is an alpha-1 agonist, and Flonase (fluticasone) is a nasal corticosteroid. Both medications help relieve symptoms like nasal congestion, swelling, and sneezing.
One study found that oxymetazoline provides faster relief for congestion, while fluticasone offers more gradual and sustained improvement. However, using a combination of oxymetazoline and fluticasone showed the greatest overall symptom relief.[2]
If you’re unsure what medicine to use, message your doctor and they’ll help you decide.
Will I get side effects using Afrin?
Answer:
It’s not common to get side effects while using Afrin, especially if you use it correctly. However, there’s a chance that some people might get side effects, like:
Itching
Irritation
Sneezing
Burning of the nose
Nervousness
For the full list of side effects, check the package insert.
What is ‘the rebound effect’ of Afrin?
Answer:
‘Rebound effect’ is the term used to describe the return of symptoms after they initially improve with medication. While it's unlikely to occur with Afrin if used correctly,[1] there’s a risk if you use it too much.
Nasal decongestant sprays like Afrin work by narrowing the blood vessels in your nose to reduce swelling and congestion. However, if used for too long, the blood vessels may swell again once the medication wears off, causing rebound congestion. This can lead to a cycle of frequent decongestant use and lead to side effects like headaches.
To prevent the rebound effect, you should only use decongestant sprays for no more than seven days. If your symptoms don’t improve or worsen, stop using the spray and ask your doctor for advice.
Can I take Afrin while pregnant?
Answer:
No, you shouldn't use Afrin if you’re pregnant. Although it's generally safe, small amounts of oxymetazoline hydrochloride enter the bloodstream, which may harm your baby.
You should also avoid using Afrin if you’re breastfeeding, as it can pass into breast milk.
Is Afrin available without a prescription?
Answer:
Yes, Afrin is available without a prescription and can be purchased over the counter at most pharmacies. The pharmacist might ask a couple of questions just to make sure it's safe for you.
It’s best to visit your doctor if you think you have an infection so they can prescribe the appropriate medication for you. Afrin can't treat the infection, it only alleviates the symptoms.
