Howard G. Smith MD, AM on Instagram: "Allergy Nasal Spray Kills Cold and CoVid Viruses Azelastine nasal spray, marketed as Astepro but also available as a generic, can reduce your chances of developing a CoVid infection by a factor of 3 and cut your chances of developing a common cold by a factor of 3.5. German researchers at Saarland University recently published their double-blind, placebo-controlled study of 450 participants in the JAMA Internal Medicine Journal. Half the subjects received azelastine 0.1% nasal spray three times a day for 56 days. The control subjects used a similarly-appearing but inactive nasal spray. Respiratory infections were confirmed using PCR analyses. The results showed that only 2.2% of the azelestine sprayers developed CoVid compared with 6.7% of controls. Only 1.8% of azelestine sprayers developed rhinovirus infections compared with 6.3% of controls. Generic azelastine spray is a prescription medication. Astepro Spray, the same medication, is available over-the-counter. If you think you might benefit, give it a try. https://jamanetwork.com/journals/jamainternalmedicine/fullarticle/2838335 #azelastine #astepro #allergy #CoVid #rhinovirus #commoncold"

Azelastine nasal spray, a prescription medication, has been found to reduce the risk of developing CoVid and common cold by a factor of 3. A study published in JAMA Internal Medicine, conducted by researchers at Saarland University, found that participants who used the nasal spray had a significantly lower risk of developing respiratory infections compared to those who did not use the spray.
