I gotta better recommendation: MyFreeDoctor.com. Fill out the application and request for a Covid19 package. Don't worry about he pharmacy, they have access to loads of them. They'll give you the treatments and prescription to follow, also purchase the nebulizer in case you need it. Give them a donation and pay the pharmacy. Store the box in a safe place until for when you need it. Presto, you'll be safe as a bug in a rug.
