The Rebound Effect of Afrin and Nasal Sprays

12/29/2011

This time of year, it’s common for folks to get some congestion in their system, making it difficult to breathe, feel stuffy-headed, and generally just not feel good. There are many types of medication available for you via prescription or over-the-counter, but it’s very important that you follow those instructions on that label – they are there for a reason.

One issue that arises in some people is what’s commonly referred to as the ‘Rebound Effect’ – particularly with medications such as Afrin.

Afrin (Oxymetazoline for those curious) is a nasal spray used to relieve nasal discomfort caused by colds, allergies, and – yes – hay fever. It is also used to relieve sinus congestion and pressure in the head.

Now, if you need it to get some sleep – the congestion is such that it makes it difficult to breathe and keeps you up at night – drugs like Afrin are appropriate to use. But only appropriate if used as prescribed: up to THREE days, in the Afrin example.

What happens is that people will continue to use it for a week, two weeks, etc. – you see it often times with the inhalers where people continue to use for extended periods.

What happens with the Rebound Effect is when the medication that constricts the blood vessels in the nasal passages wears off, you’ll have an exaggerated response where those same blood vessels will dilate and become swollen. They will then produce fluid, and you’re back to being congested again.

Also, something to note as you get older, these medications are stimulants – and if they are overused can precipitate heart attacks. So it is very important to make sure you follow the instructions and don’t overuse these medications – for the short term and long term.

Don’t get carried away with nasal decongestants – you may end up back where you started. If you’ve got questions on the proper use of these medications, please consult your physician, and get back to breathing right!

Be Well,
