Do nasal sprays actually work against COVID-19? Can I use nasal spray if I have COVID-19?  The COVID-19 pandemic has been roaring on for 3 years. During this time, the FDA has authorized many treatments  that help combat COVID-19. COVID-19 vaccines have also been recommended by the CDC ever since the first ones were authorized in December 2020. However, medications that are already authorized are just a small percentage of what's been studied. Many researchers are still trying to find and develop other medications that can treat or prevent COVID-19. Among these, nasal sprays have caught the attention of many people. They’re often easy to use, and some researchers believe they could have a potential impact on the ongoing pandemic. But are any of them effective at treating or preventing COVID-19? And are any of them close to being available in the U.S.?  Which nasal sprays have been studied to treat or prevent COVID-19? A number of nasal sp...

Pulse oximeters, which simply clip onto your fingertip, are non-invasive devices that can measure blood oxygen saturation as well as pulse (heart rate). They are relatively inexpensive (about $20) and can be purchased for home ("non-medical") use. The best pulse oximeter for home use will probably be different from the best pulse oximeter in a hospital. Although pulse oximeters for home use are not as accurate as FDA-approved "medical" pulse oximeters, which cost much more and undergo more rigorous testing, comparison studies indicate that some (but not all) non-medical pulse oximeters can help signal when medical attention is needed in conditions such as COVID-19, asthma, and chronic obstructive pulmonary disease (COPD). Collecting data on oxygen levels is crucial because people with COVID-19 may suffer from "silent hypoxia", a dangerous condition in which they do not outwardly appear to be short of breath, but are  confirmed to be so through a pulse oxim...
