Getting Perscriptions: I got my Ivermectin, Hydroxychloroquine and Budesonide prescriptions from a telehealth doctor via the app called Medici. It took around 14 days for a doctor to contact me via their messaging app since I was seeking medications prophylactically (and not symptomatic) so I was at the bottom of the list. I told them I wanted to be prepared in case I got any viruses. These doctors work as volunteers and the suggested donation was $100.
PushHealth is another way to set up a virtual doctor visit to get a prescription for those drugs. I haven't used it but other people have had success.
My recommendation: Just be upfront about wanting to get some prescription meds in case you contract Covid and want to treat at home when you contact these doctors. Thousands of people have been using these platforms to get the prescriptions! Way to be proactive! It's better to have it before you need it because sometimes it takes a long time to get through to a doctor because the demand is so high but the doctors that will prescribe are few and far between.
