About Rivas Medical Weight Loss
Billing is weekly rather than monthly, and the dose never changes it: $115/week for compounded semaglutide, $165/week for compounded tirzepatide, each week's figure paying for a provider visit as well as the drug. Paul Rivas MD LLC pairs telehealth with 15 physical clinics spread over Maryland, Virginia and Florida. Seeing a provider every week costs more than ordering by mail from competitors.

Rivas Medical Weight Loss
What we like
- Publishes a price on its own site before the medical questionnaire, so it can be compared without handing over health information
- The monthly price is recorded as flat across doses, so it does not climb as the dose is titrated up
- The monthly figure covers medication and consult
- No FDA warning letter matched this operator when we searched our enforcement register
Watch-outs
- Semaglutide at $498 a month, 163% above the $189 register median for the same drug and form
- Tirzepatide at $715 a month, 168% above the $267 register median for the same drug and form
- Coverage is published for 3 states only, so this may not reach you
- No dispensing pharmacy is named in our record, so its accreditation cannot be looked up from here
- Its semaglutide and tirzepatide are compounded rather than FDA-approved, so they have not been reviewed by the agency for safety, effectiveness or manufacturing quality
