Azelastine nasal spray is available over the counter in the United States, but only at the 0.15% strength and only for adults and children ages six and older. The FDA approved this switch from prescription to nonprescription in June 2021, making it the first nasal antihistamine ever sold without a prescription. Other forms of azelastine, including eye drops and the combination spray with fluticasone, still require a prescription.
What Went OTC and What Didn’t
The FDA approved a “partial switch” for azelastine, which means only part of the product line moved to nonprescription status. The version you can buy off the shelf is Astepro (azelastine hydrochloride 0.15%), now sold by Bayer Healthcare. It’s approved for both seasonal allergies (hay fever) and year-round allergies in people six and older.
The lower-strength version, azelastine 0.1%, remains prescription-only. That formulation covers younger children: it’s used for year-round allergies in kids as young as six months and seasonal allergies in children ages two to five. If your child falls into that age range, you’ll need a prescription.
Two other azelastine products also stay behind the prescription counter:
- Azelastine eye drops for allergic conjunctivitis (itchy, watery eyes from allergies).
- Azelastine-fluticasone combination spray (sold as Dymista), which pairs the antihistamine with a steroid nasal spray in a single bottle.
How It Works
Azelastine is an antihistamine, but unlike the pills you might be used to (cetirizine, loratadine), it’s sprayed directly into the nose. That means it starts working at the site of your symptoms rather than circulating through your entire body first. It blocks the histamine receptors in your nasal passages that trigger sneezing, congestion, runny nose, and itching. Most people notice relief within 15 to 30 minutes, which is faster than many oral antihistamines.
How to Use It Properly
The technique matters more with azelastine than with most nasal sprays, because poor form leads to the medication dripping down your throat and leaving a bitter taste. This is the most commonly reported side effect, and it’s almost entirely preventable with the right approach.
When you spray, tilt your head forward and down (look at the floor, not the ceiling). Press the pump once and sniff gently at the same time. You don’t need a forceful inhale. A soft sniff keeps the medication on the nasal lining where it belongs instead of pulling it toward the back of your throat. If you’ve ever used a nasal spray and immediately tasted something unpleasant, you were likely tilting your head back or sniffing too hard.
If you’re opening a new bottle or haven’t used it in several days, you’ll need to prime the pump by pressing it a few times until you see a fine mist. Point the nozzle away from your face and other people while priming.
Side Effects
Azelastine’s side effect profile is mild. The bitter taste is by far the most common complaint, and as noted above, proper spray technique largely eliminates it. Drowsiness is the other side effect people worry about, since older antihistamines like diphenhydramine are notorious for causing it.
In clinical trials submitted to the FDA, drowsiness rates with the 0.15% spray were low. Roughly 1% of users reported sleepiness, compared to about 0.3% to 0.6% on placebo. That’s a real but small difference. Still, it’s worth being aware of the first time you use it, especially if you’re also taking oral antihistamines or anything else that causes drowsiness. Fatigue showed a similar pattern, affecting under 1% of people in trials.
How It Compares to Other OTC Allergy Options
Most OTC allergy medications fall into two categories: oral antihistamines (cetirizine, fexofenadine, loratadine) and steroid nasal sprays (fluticasone, budesonide, triamcinolone). Azelastine occupies a different niche as a nasal antihistamine, and that gives it some practical advantages.
Steroid nasal sprays are considered the most effective single treatment for nasal allergy symptoms, but they take days to reach full effect. Azelastine works much faster, making it useful on days when symptoms flare unexpectedly or when you need relief before a steroid spray has had time to build up. Some allergists recommend using both together for stubborn symptoms, which is essentially what the prescription combination product (azelastine plus fluticasone) provides in one bottle.
Compared to oral antihistamines, azelastine tends to be more effective at relieving nasal congestion specifically. Pills do a good job with sneezing, itching, and runny nose, but congestion often persists. Because azelastine delivers the medication directly to swollen nasal tissue, it addresses stuffiness more directly.
Cost and Where to Find It
You’ll find OTC azelastine in the allergy aisle at most major pharmacies and retailers, as well as online. It’s sold under the Astepro brand name and increasingly as store-brand generics. Pricing typically falls in the range of other brand-name OTC nasal sprays, though generics can bring the cost down. If you previously used prescription azelastine and paid a copay, the OTC version may actually cost less depending on your insurance plan, since many insurers stop covering a product once it becomes available without a prescription.
