If you want Ivermectin and you are having trouble getting it from your doctor or pharmacy, this website can give you a prescription and lists online pharmacies that will fulfill the prescription

Since this is run by volunteers, try getting a prescription from your doctor first. Consider switching from an MD to a DO since DOs tend to be more skeptical of the health authorities. If you can't get a prescription from your doctor, this organization has volunteer doctors who can get you a prescription. Try to get your prescription filled at a small local pharmacy rather than a corporate one, but if they refuse, this site lists online pharmacies that are willing to send Ivermectin to people with a prescription. Be aware that shipping times can take too long to be effective if you wait until you're sick to go through this process.
