Didn't even get to try the product since the button exploded as soon as I took the cover off. Cheap plastic mangled and couldn't bee put back together.

Good Medicine
the design of the applicator is awful it does not allow the medicine to be properly administered. It fills the nostril and you must breathe deep to get part of the medicine to somewhat enter the congested sinus. I feel that spending the extra money for the other brand , same medicine, for the ease of use Isa better option. Or please redesign the applicator.

Works amazing!
I was so stuffy from my cold. Literally couldn’t breathe out of my nose at all. With this it dried my sinuses up for hours!!! It’s worth it.

Best Nasal Spray!
This spray is A M A Z I N G. It works so so so good. As someone who gets stuffy noses a lot and sinus infections this HELPS! As soon as its in use give it like 2-3 minutes and my nostrils are CLEAR like im not in the middle of a cold. The easy accessible thumb button is perfect and its so small it fits rights into my fanny pack/small purse! I was scared at first to try it cause I have used Flonase and it made my nose bleed immediately and i stopped using it so i was a little hesitant but it works GREAT

Great nasal decongestant!
[This review was collected as part of a promotion.] This nasal decongestant has been a lifesaver at all times! Great to clear up nasal allergies, or just a stuffy nose in general. I use it frequently and will continue to repurchase!

SUPERB!
[This review was collected as part of a promotion.] theraflu is a brand I've always trusted for flu and cold season as my go to brand for their powder drink mixes- when I learned they made nasal sprays, I was thrilled to be able and try the product! As always ,Theraflu did NOT disappoint! The product does exactly what it says it will do and it certainly is effective! The packaging quality is top notch especially the way the cap and sprayer are designed!

Good for stuffy noses
[This review was collected as part of a promotion.] Thank you theraflu and Influenster. My daughters and I have horrible allergies from spring flowers and fall trees. The pollen is evil for us! Thankfully there are products like this nasal mist for severe congestion that quickly breaks up the dried mucus and allows us to breath freely! Main ingredient is oxymetazoline hcl

Works Fast and Long-lasting!
[This review was collected as part of a promotion.] My husband has bad allergies that cause him to suffer from really bad congestion, especially after doing yard work. I urged him to try this nasal spray and it worked for him almost immediately! The effect also lasted for several hours. He said it worked better than Affrin, which he uses a lot during the spring months. Once he runs out, I will be sure to stock up on more for him!

Inexpensive
[This review was collected as part of a promotion.] It hit me like a bus. It worked so fast especially when I was sick. I always get super congested when I’m sick and can barely breath out of both nostrils so this came in handy. I love the packaging it’s small and fits in a bag or medicine cabinet at home. It’s not expensive so I would definitely buy it if I run out.

Not for me
[This review was collected as part of a promotion.] I unfortunately did not care for this nasal mist from Theraflu. It had a sour taste that lingered in my sinuses and hours later my throat is feeling much worse and it didn’t seem to relieve any sinus pressure for me.

Burns but powerful!
[This review was collected as part of a promotion.] super efficient packaging! So easy to use I love it! It did clear my nose very very well, it does burn though!!! I thought the burn would go away it’s been about an hour but still burning! Not like a peppermint burn but like a stinging one. I am so grateful to have relief so I don’t even care about the burn, I’d take it over being congested. I get to sleep easy tonight thanks to Theraflu

Great for sinus sufferers.
[This review was collected as part of a promotion.] This theraflu spray really helped with my nasal congestion and cold. I used it either when I woke up or before going to bed. You must read the instructions as it says do not use this product than 3 days. The only difficulty I had was opening the top as it was slightly hard to open. This definitely was great for sinus suffers as well.

Congestion free!
[This review was collected as part of a promotion.] I absolutely loved the Theraflu Severe Congestion Relief Nasal Mist! It unblocks my nose within minutes and gives almost instant relief. I’ve tried other sprays, but this one really stands out—it works fast and doesn’t irritate. Total game changer, especially during allergy season or when I’m feeling under the weather. Highly recommend!
