Important Safety Information

Compounded medications

Compounded medications are not FDA-approved and have not been reviewed by the FDA for safety, effectiveness or quality.

About compounded medications

Compounded medications are prepared by a state-licensed pharmacy for an individual patient under a valid prescription when a licensed provider determines a compounded product is medically appropriate. They are not generic versions of any brand-name drug, and results from clinical studies of FDA-approved products do not apply to compounded products.

Injection-site reactions

Common side effects of injectable medications include redness, pain or swelling where you inject. Contact your provider about any side effect that bothers you or does not go away.

Report side effects to your provider through your patient portal, or to the FDA at www.fda.gov/medwatch or 1-800-FDA-1088. All safety information

Online visits are reviewed by independent, US-licensed healthcare providers (physicians and nurse practitioners) licensed in your state. Prescriptions are filled by state-licensed US pharmacies. Compounded medications are prepared by state-licensed 503A compounding pharmacies. Product images are for illustration only; actual product appearance and labeling will differ.

Common questions See all FAQs

How does pricing work?

Every product shows its price upfront, including your provider visit, the medication and shipping. There are no membership fees. A 3-month supply costs less per month than monthly.

How do I get a prescription?

Choose a product and complete a short online visit. A healthcare provider licensed in your state reviews it. A prescription is issued only if the provider decides treatment is appropriate for you. If you are not approved, you are not charged for the medication.

Are compounded medications FDA-approved?

No. Compounded medications are not FDA-approved and have not been reviewed by the FDA for safety, effectiveness or quality. They are prepared by state-licensed pharmacies under a valid prescription, and they are not generic versions of brand-name drugs such as Wegovy® or Zepbound®. Each product page states whether it is compounded or FDA-approved.
