Feelrx operates as a marketplace platform connecting patients with independently licensed healthcare providers who deliver care through the Feelrx Patient Portal. Feelrx does not dispense medication or provide medical services directly; all clinical decisions rest solely with independent providers. Payment does not guarantee that a prescription will be written or that medication will be dispensed. Any prescription issued reflects only the professional judgment of the healthcare provider.

Where we operate: Feelrx services are available only to patients physically located in U.S. states where our affiliated providers are licensed. Availability varies by state, by treatment, and over time, and some products and lab panels are not offered in every state. Eligibility is confirmed during intake, and if care cannot be offered in your state you will not be charged. Email care@feelrx.com to confirm availability where you live.

Prescription products: medications shown on this site require a valid prescription from a licensed provider following an evaluation. Pricing reflects the cost of the medication and associated clinical services when prescribed; it is not an offer to sell a prescription medication and does not guarantee approval.

Subscriptions: multi-month plans are billed as described at checkout and renew automatically until cancelled. You may cancel at any time before your next renewal by emailing care@feelrx.com or calling 408-930-6688 . See our Terms of Service and Returns & Refunds policy.

The information on this site is provided for general informational purposes only and is not a substitute for individualized medical advice, diagnosis, or treatment. Always consult your licensed healthcare provider about any medical concerns. This platform advertises healthcare services, not any specific prescription medication.

Disclaimer: FDA-approved brand-name medications, including Wegovy® and Ozempic®, are made and distributed solely by Novo Nordisk®. Mounjaro® and Zepbound® are made and distributed solely by Eli Lilly and Company®. care@feelrx.comis not affiliated with, endorsed by, or sponsored by any of these companies or their products.

Compounded medications are not reviewed or approved by the U.S. Food and Drug Administration (FDA) for safety or efficacy. They are, however, prepared by licensed compounding pharmacies in accordance with Section 503A of the Federal Food, Drug, and Cosmetic Act, which permits compounding based on a valid patient-specific prescription from a licensed healthcare provider.
