Can a 503A Compounding Pharmacy Advertise to Prescribers on Google and Meta?

What this means for you

• Google's US healthcare rules have no exception for ads shown only to prescribers. The one healthcare-professional exception on Google's page sits under Japan.
• A pharmacy that fills by mail or remote ordering counts as an online pharmacy for Google, and needs LegitScript or NABP accreditation plus Google certification before its ads serve.
• Target only the states where the pharmacy is licensed. Google treats targeting locations where you aren't licensed as an egregious violation.
• On Meta, naming a prescription drug needs active LegitScript certification and Meta's authorization.
• Disclose every domain you operate to LegitScript, sister sites included, and keep FDA's compounding claim limits on all of them.

MedScale Health, a paid acquisition agency for telehealth brands and clinics, runs Google and Meta campaigns for 503A pharmacies that sell to telehealth companies and prescribers. This page sets out the platform and FDA rules that apply when the audience is prescribers rather than patients. This page is marketing guidance, not medical or legal advice. Platform policies change, so check the sources listed at the end before acting on a specific rule.

No prescriber-only carve-out on Google

Google's Healthcare and medicines policy restricts the promotion of services related to the online prescribing, dispensing and sale of prescription drugs, and names online pharmacies among the businesses in scope. Its US section allows online pharmacies accredited through LegitScript's Internet pharmacy certification, which Google describes as available to websites that accept refills, transfers or new prescriptions, or to pharmacies that fill via mail-order or another remote ordering service, or through NABP's Digital Pharmacy Accreditation or .Pharmacy programs. Advertisers must also be certified with Google.

A campaign aimed at doctors is not exempt. Google's page has one exception for websites accessible only to healthcare professionals, and it sits in the Japan section, where it lets such sites use prescription drug terms in keywords. The US section has no equivalent. Google also says it errs on the side of caution with landing pages that appear to facilitate the online sale or dispensing of medicines, and that in judging pharmacy violations it may review your ad, website, accounts and third-party sources.

Licensed states and Google's targeting rule

Google's Unauthorized pharmacies policy says offering prescription drugs without a prescription is not allowed and targeting locations where you aren't licensed is not allowed. Google treats violations as egregious: accounts are suspended upon detection and without prior warning, and reinstated only in compelling circumstances. Build the location list from active licenses only. Pending applications don't count, and a license limited in scope should be cleared with counsel before its state goes in. Drug names follow the Restricted drug terms policy: in the US they can appear in ads and landing pages without certification, but keyword-targeting them requires it.

Meta for pharmacies

Meta's prescription drug rules require online pharmacies to be actively certified with LegitScript before applying for authorization, and authorized advertisers may promote prescription drugs only to people 18 and over in the US, Canada or New Zealand, in the countries where they are certified. Meta's exemption covers ads that promote telehealth services generally and says nothing about pharmacy services, so an ad that names a compounded drug needs certification and authorization. Write the ad for the prescriber: turnaround, states served, how prescriptions are sent and how patients receive them.

Microsoft and LinkedIn, for completeness

Microsoft Advertising requires online pharmacies to be preapproved, and its US rules say online pharmacies advertising prescription drugs must be accredited by NABP or LegitScript. It also requires compounded weight loss drugs to be labeled with "This is a compounded drug" or an equivalent disclaimer. LinkedIn's advertising policies say ads promoting pharmacy and telehealth services are restricted, require prior authorization, may only run in the United States and must not target members under 18. MedScale runs Google and Meta; these rules are listed so the picture is complete.

LegitScript: every domain, every affiliate

LegitScript lists compounding pharmacies and mail-order pharmacies among businesses eligible for Healthcare Certification. Its standards require applicants to be licensed in the jurisdictions they serve, including where the patient is located, to provide all domain names and websites under their control, and to disclose all affiliates. Its pricing section says all operated domains must be disclosed, even though you choose which to certify. A sister site with unsupported claims is part of the review, because LegitScript's transparency standard covers claims of benefits not supported by a regulatory body such as the FTC or FDA.

FDA limits on compounding claims

FDA's chart of FD&C Act provisions says section 503A compounding must be based on a valid prescription for an identified individual patient; it can happen after the prescription arrives, or in limited quantities before it. Copy should describe filling patient-specific prescriptions, not supplying stock. Drugs compounded under 503A are exempt from premarket approval, which is why they are not FDA-approved.

FDA's reminders to telehealth companies promoting compounded drugs list as misleading: calling a compounded drug a generic or the same as an approved drug, claiming FDA approval, and claiming it comes from an FDA-approved or FDA-licensed pharmacy, because FDA does not approve or license any facility. Ingredients matter too. FDA keeps a list of bulk drug substances that may present significant safety risks, current as of April 22, 2026, and it is worth checking before any ingredient appears in an ad or on a sister site.

What MedScale does

MedScale Health builds prescriber-facing Google and Meta campaigns for 503A pharmacies once certification is in place, limits location targeting to active licenses, writes copy within FDA's compounding claim limits, and checks every domain the pharmacy operates before launch. MedScale tracks server-side under a BAA with neutral event names, and no names, emails, phone numbers, IP addresses or browser IDs go to any ad platform. No volume of new prescribers is promised.
