Check labels and ingredient lists when purchasing over-the-counter medications to ensure they don't contain sulfa compounds. It's advisable to consult with a pharmacist if you are uncertain about the ingredients.
Always inform your doctors, dentists, and pharmacists about your sulfa allergy. This ensures that they avoid prescribing medications containing sulfa, and instead, they can provide you with alternative options.
Consider wearing a medical alert bracelet or necklace that indicates your sulfa drug allergy. This can be critical in emergency situations where you might be unable to communicate your allergies to healthcare providers.
Utilize smartphone apps designed to manage allergies. These apps can help track and list medications you should avoid and provide reminder alerts to check medication labels when filling prescriptions.

Your immune system gets desensitized to allergens, giving you long-term relief.
It’s a physician-prescribed, custom-compounded formula designed to target all your nasal symptoms at once — congestion, runny nose, post-nasal drip, sneezing, and more.
Formulated by doctors and pharmacologists and backed by clinical research, Quickie combines five powerful ingredients into one easy spray.
Typical prescription may include the following ingredients: Azelastine HCL 0.15%, Mometasone Furoate 0.05%, Oxymetazoline HCL 0.0125%, Ipratroprium 0.06%, Sodium Hyaluronate 0.04%.
Straight to the source. That’s Curex
Quickie is a compounded prescription medication, prepared by a licensed pharmacy. It is not reviewed or approved by the FDA. It is prepared based on your provider’s evaluation of your symptoms and needs. Individual results may vary.
Lauren S.
No longer having to go the doctor's office a few times a week for painful shots.
Tony P.
I have done allergy shots in the past but found it pretty inconvenient to go every week. I really like the ease as compared with physically going to the doctors office.
Robert S.
The treatment is much less expensive than a course of allergy shots at a doctor's office and eliminates numerous trips to the doctor's and all the waiting time.
Janie L.
My seasonal allergies were much less severe than years prior. Most importantly, the convenience of taking drops in my own home is unbeatable.

Most patients feel relief within 15 minutes. We have both short-term relief ingredients as well as longer-term relief to keep you feeling better, longer. Some say it’s like turning off their allergies.
Sneezing runny nose, nasal congestion, post-nasal drip, sinus pressure, itchy nose. Great for outdoor allergies, indoor dust, or when pollen spikes unexpectedly.
No, this formula uses a microdose of oxymetazoline, balanced with anti-inflammatory and moisturizing ingredients to reduce the risk of rebound congestion. Clinical studies over the last decade show that when oxymetazoline is combined with a corticosteroid, it can be used safely over the long term without causing rebound symptoms.
Quickie Spray combines up to five prescription-strength ingredients into a single, personalized formula — targeting multiple symptoms like congestion, post-nasal drip, and inflammation. OTC sprays typically address just one symptom and lack the synergy of a customized blend.
Some ingredients like azelastine may cause a slight taste, but many patients find it milder than traditional OTC sprays. Proper spray technique (head forward, not tilted back) helps minimize drip.We also offer an alternative formulation with olopatadine, which has a gentler taste profile and may be preferred by taste-sensitive patients.
Quickie is designed to replace most other allergy medications. But it is designed to compliment allergy immunotherapy for long-term relief. If you’re currently taking other antihistamines or nasal sprays, tell your Curex provider, so we can adjust your formula to avoid overlap or interactions.
No, Quickie is a personalized compounded prescription prepared by licensed U.S. pharmacies based on your doctor’s evaluation. Compounded medications are not FDA-approved as commercial products, but they are regulated under federal and state pharmacy laws.
Possible side effects include nasal dryness, mild irritation, or occasional nosebleeds. These are typically mild and manageable. Let your Curex provider know about any bothersome or serious effects, so we can fine-tune your prescription if needed.
Quickie is safe for daily use, especially during the first 3–6 months of allergy immunotherapy, when symptoms are still active. Your Curex provider may adjust your dose or frequency as your immune system builds tolerance.
Quickie is designed to be non-sedating, so you can use it before work, school, or exercise without feeling groggy or foggy. In rare cases where drowsiness is reported, let your Curex provider know—we can easily adjust the formula to better suit your needs.
Yes, Quickie Spray can be prescribed for children aged 6 and up, based on your provider’s clinical evaluation.
Follow the instructions from your Curex provider.Most patients are advised to use one spray per nostril, twice daily — morning and evening — for consistent relief.
