Hi @danye1, The 3 ingredients are Mometasone to reduce inflammation, Ipratropium to reduce nasal drainage and Diphenhydramine which is an antihistamine to help reduce nasal drainage. The product description on my prescription is MOMET 0.033% – IPRA 0.02% – DIPH 0.02%. I think an ENT doctor may be able to write an RX so that you can get it from a Mayo Clinic Pharmacy but you may want to talk with your doctor and/or give the Mayo Pharmacy a call. Here's the Mail Order phone information:

Does your ENT think that part of your problem with the congestion may be related to rhinosinusitis. Since using the proprietary nasal spray along with a twice daily nasal rinse, I've switched to using the SinuSonic Sinus Therapy - https://sinusonic.com/. Each device lasts about 6 months and is about the same as paying for the twice daily nasal rinse supplies. I was surprised at how well it has worked for me. Here's a study that I found on the device prior to buying one. I've used one for a couple of years now and it has pretty much cleared my congestion as long as I use it once or twice a day. I normally just use it before going to bed.
