Can You Overuse Nasal Spray?

Yes. Just ask Marianne McCall. A few allergy seasons back, she thought her seasonal congestion might never end. In April, she’d begun to use a topical nasal-spray decongestant. The over-the-counter (OTC) drug worked like a charm.

By summer, she was still using the spray daily. Yet it was helping for shorter and shorter periods. Between doses, her congestion was getting worse.

What happened to McCall is known as the rebound phenomenon. You spray and spray, several times a day, but your stuffy nose seems to get worse.

It’s a well-known problem, says Marilene Wang, MD, an ear, nose, and throat doctor in Los Angeles. The condition’s official name is rhinitis medicamentosa, and it has one cause: overusing decongestant nasal sprays.

These sprays contain chemicals that shrink congested blood vessels. That’s how they open up your clogged passages. Because they’re applied directly to the nose, they give you quick relief.

After a few days, though, the blood vessels don’t respond to the medication anymore. You spray away, but your problem just gets worse. This cycle can continue for months, years, and even decades.

That’s why every bottle comes with a warning: “Do not use for more than 3 to 5 days.” McCall read the labels, but “I didn’t think a couple more days would make a difference,” she says.

She was wrong.

The longer you use a spray decongestant, the more likely you are to get the rebound phenomenon. It can lead to chronic sinusitis and other serious, long-term problems.

Give your doctor a call if you're having any of these issues:

It’s all in your nose. Allergies typically have more than one symptom, like itchy, watery eyes. But nasal spray overuse has just one: nasal congestion that won’t go away.

You can’t pinpoint a trigger. Your problems don’t change with the season, or relate to other triggers. If you’re stopped up all the time, it’s not likely an allergy.

The spray doesn’t help. Your congestion is getting worse, even though you’ve increased the nasal spray dose and how often you use it.

You have symptoms of withdrawal. When you stop the spray you get headaches, sleep trouble, restlessness, and anxiety.

You can take these steps to avoid getting hooked.

Try other decongestants. Oral antihistamines and decongestants -- which you take by mouth -- have a different mix of chemical ingredients and don’t all bring the same risks. Some are unsafe for people with high blood pressure, though.

Switch methods. Use a nasal saline (like a nasal rinse or Neti pot).They can flush out stuffy airways.

Cut the cord. Don’t use a spray more than once every 12 hours, or longer than 3 days.

There’s only one permanent solution -- you have to stop using the nasal spray. It’s probably going to take a few weeks, and the first week will be the hardest.

Your doctor can help find the best way to ease your discomfort.

“We sometimes prescribe a short course of oral steroids to help patients get over the initial severe congestion that occurs while trying to quit the nasal decongestants,” Wang says. “We may also recommend other treatments, such as drugs for allergy control, nasal emollients, or alternative therapies.”
