JASE medical at https://jasemedical.com/ is a site in the US staffed by US licensed doctors who will provide a "prepper" supply of most commonly required prescription antibiotics. They say that the kit is meant for one person. They will do an intake assessment and based on medical information will provide a prescription for medicines. In the event of allergies to meds, they will prescribe alternates.
