Can Nasal Steroids Ease Allergy Symptoms?

Nasal steroid sprays offer relief from congestion, sneezing, watery eyes, a runny or itchy nose, and postnasal drip. They are one of the first treatment options recommended for symptoms of allergic rhinitis.

Examples include budesonide (Rhinocort) and mometasone (Nasonex), both available by prescription, and fluticasone (Flonase Allergy Relief), budesonide (Rhinocort Allergy), and triamcinolone (Nasacort Allergy 24 Hour), which are available over the counter. The prescription nasal spray azelastine and fluticasone (Dymista) combines an antihistamine with a steroid.

Allergy symptoms such as nasal congestion happen because of inflammation (swelling). Nasal steroids cut swelling, mucus, and congestion in your nose. As a result, your nasal passages are less sensitive and are less likely to get irritated by triggers such as pollen, animal dander, or dust mites.

Nasal steroid sprays are not the anabolic steroids some athletes take to bulk up their muscles. Rather, they are corticosteroids, which are man-made drugs that are nearly the same as a chemical, called cortisol, that your body makes naturally. They are some of the most effective medicines for treating allergy symptoms and often recommended first.

You spray these steroids directly in your nose. So, most allergy experts feel there is little if any chance of serious side effects on other parts of your body.

Mild side effects are rare, but irritation, headache, and a bloody nose can happen.

While these drugs start working within a few hours, you might not notice the full benefit for several days to weeks. You can take them with other allergy medications if needed. Your doctor might ask you to stop the other drugs to see if the nasal steroids work by themselves, though.

Read the directions on the package, or ask your doctor to show you how to use the spray. Depending on the type of nasal steroid, the instructions may be different. For example, with some, you have to tilt your head slightly forward. With others, you have to tilt your head slightly back.

The goal is to make sure the medication stays in your nose and doesn’t run down the back of your throat. To help, breathe in gently through your nose as you spray. Also, spray away from your nasal septum (the wall between your nostrils) to avoid irritation.
