Treating underlying allergies can significantly reduce Sinusitis flare-ups. Chronic sinusitis is often caused or worsened by untreated allergies. By using our personalized allergy drops to desensitize your immune system, Wyndly helps reduce inflammation, congestion, and sinus pressure — leading to fewer sinus infections and easier breathing.

from 89 reviewsSo easy to do. Great response when I have questions. I just love it!
It has worked great for me.
I very much appreciated the straightforward discussion I had with the doctor, and the information he provided. I also appreciate his promptness for the meeting andthe details on how this process would work.
Good consultation. Was sent the test and mailed it in. Waiting on results and prescription plan. So far I'm happy with Wyndly.
Easy to use. My questions are addressed in a timely manner. Also liked that I could speak to an allergy specialist doctor (virtually) about my treatment plan. Very helpful and will recommend to anyone on the fence about trying it.
Great Allergy medicine
Only had my initial intake so far, but it was super easy and I’m excited to give it a go. This could be life-changing!
So far my experience with Wyndly has been great. Communications and Doctors visit was 5 star and I'm sure my treatment and future experience will be 5 star as well. Thank you Wyndly!!
I find that the process in signing up and starting treatment is simple and straightforward. I am looking forward to achieving allergy free results
13 months in and allergy symptoms are becoming manageable. I'm very optimistic about the end result
After YEARS of dealing with severe allergies, undergoing multiple shots each week along with other medications I was directed to Wyndly. What an amazing life style change.
After submitting my allergy test I received a vial of allergens with directions to put 3 drops under my tongue daily. Within a very short time I was no longer suffering with all the symptoms associated with allergies and I no longer have to deal with weekly shots that were never as effective as the 3 daily drops.
The staff has been extremely helpful ensuring I receive refills on time.
My allergies were so bad they were almost debilitating on some days. I had been to two different allergists for help and testing. I tested for severe allergies to dust (I live in west Texas so there's no stopping blowing dust!), cats, and mold. I was told that even though they were severe, I didn't have enough "other" severe allergies to receive allergy shots. I read about Wyndly and decided to give it a shot. It has helped me tremendously! I still have a few bad allergy days but they don't make me feel sick and lethargic anymore. It's been so great to feel validated and actually receive help to get better.
Tired of getting allergy shots? Tired of making frequent trips to doctor? Then Wyndly is your best bet. Saw the ad on instagram and proceeded further with skepticism. But, surprised with their process and results. After using for 4 months, I saw the results and I am normally bed ridden in spring through summer. But this year, did not feel a thing. Just few drops under the tongue did the magic. Surprisingly they tasted sweet. :) Sweet deal.
I'm a lifelong allergy sufferer, and moving to a new state stirred up the worst allergy problems I'd ever had. I did a 3 year course of immunotherapy with multiple shots every week, and that helped tremendously. However, after several years the benefit started to wear off. I heard about Wyndly and decided to give it a try. I almost immediately started to see an improvement in my symptoms and continue to get better by the day. This sure beats a 45 minute round-trip drive to an allergist each week! Would highly recommend Wyndly to anyone with bad allergies.
I've been using Wyndly drops for about 18 months now and have noticed a significant reduction, if not outright elimination, of allergy symptoms throughout the year. The service is easy, only requires an at-home allergy test and the drops are shipped.

How long does it take for my doctor to review my allergy history?
Our doctors typically review your history to see if you're a candidate within a few hours, and they will always complete the review within two business days. You'll get an email or text message asking you to schedule your follow-up when they've reviewed your history.
When will I feel better? Do I have to be on immunotherapy forever? How quickly will Wyndly work?
Studies show that patients see improvements in their allergy symptoms as early as 4 weeks, with very significant improvements after 6 months. All immunotherapy has similar treatment lengths due to similar medicines. For lifelong relief, patients stay on allergy shots for 3-5 years. At Wyndly, we see most of our patients complete their immunotherapy in 3 years.
How long will the results last?
Studies on patients using allergy immunotherapy have shown continued benefits at least eight years after stopping therapy. Most doctors would say allergy immunotherapy provides lifelong allergy relief.
The American Academy of Otolaryngology considers sublingual immunotherapy allergy drops capable of "help[ing] patients experience relief from allergy symptoms and improve their overall quality of life."
