Private label OTC manufacturers are FDA-registered drug makers that produce over-the-counter drugs (pain relief, sunscreen, acne treatments, antiseptics and similar) and package them under your brand. Unlike cosmetics, OTC drugs follow drug rules: the product must fit an FDA OTC monograph or an approval, be made under drug cGMP, carry a Drug Facts label, and be listed with the FDA under a code that identifies your brand. Published minimums from US makers start around 5,000 units. The good news for brand owners: under FDA rules, a private label distributor that doesn’t make or relabel the drug doesn’t register an establishment, but does need its own NDC labeler code.
I’ll compare manufacturers, then explain monographs, registration and labeler codes, labeling, and Amazon. Drug rules are strict. They’re also clear.
Private label OTC manufacturers and minimums
From each company’s own site, checked in October 2026:
| Manufacturer | Location | Published minimum | Notes |
|---|---|---|---|
| Tropical Labs | Tampa, Florida | 5,000 units for OTC products | |
| Pure Source | Miami, Florida | 5,000 units or more | Says it runs an FDA-registered, cGMP facility; makes sunscreen, acne and pain-relief products |
| Product Management Group | Boca Raton, Florida | Stock OTC formulas from 5,000 units | 90 to 150 day lead times; may act as a broker rather than a manufacturer |
| AMF Pharma | Ontario, California | 300,000 tablets or capsules, or 5,000 to 10,000 vials | 4 to 8 week lead time |
My take: OTC is not a first private label product. Start with cosmetics to learn the process, then move into OTC with an experienced, registered drug manufacturer. If you’re unsure whether a supplier actually manufactures or brokers, I’d ask to see their FDA establishment registration. Every time.
How the OTC monograph system works
An OTC drug monograph sets the conditions (active ingredients, uses, doses, routes, labeling and testing) under which an OTC drug is generally recognized as safe and effective. The CARES Act of 2020 reformed the system: the FDA now updates monographs through administrative orders, and companies can request changes through OTC Monograph Order Requests. It also created OTC monograph user fees, including facility fees paid by owners of OTC monograph drug facilities, contract manufacturers included.
In practice: your product must match an existing monograph exactly (active, strength, claims, labeling), or it needs an approved application. No improvising. The CARES Act was signed on March 27, 2020, and the FDA describes a comment period of at least 45 days on proposed monograph orders. Our guide to private label face masks shows a monograph example: acne actives such as salicylic acid at 0.5% to 2%.
Registration, listing and your NDC labeler code
FDA rules (21 CFR Part 207) separate who does what:
| Party | What they do |
|---|---|
| Manufacturer, repacker, relabeler | Registers each establishment with the FDA |
| Private label distributor (your brand, if you only sell under your label) | Not required to register; must apply for an NDC labeler code |
| Manufacturer | Lists the drug under your trade name, using an NDC that includes your labeler code |
So when your manufacturer lists your product, the National Drug Code on your box carries your company’s labeler code. Your code. Not theirs. Honestly, this is the step that surprises most new OTC brands. Plan for it early.
Manufacturing and labeling
- cGMP: drug manufacturing follows 21 CFR Parts 210 and 211; products made outside those rules are considered adulterated.
- Drug Facts: OTC labels must follow the Drug Facts format (21 CFR 201.66), with the “Drug Facts” title and required sections.
Ask your manufacturer to draft the Drug Facts panel for you. Then have a regulatory specialist review it before printing. In my view, that review is the best money you’ll spend on an OTC launch.
How to launch a private label OTC product, step by step
- Pick a monograph product with a clear, permitted use, such as an acne treatment or a first-aid antiseptic.
- Shortlist registered manufacturers and ask for their FDA establishment registration and recent inspection history.
- Apply for your NDC labeler code as the private label distributor.
- Confirm the formula matches the monograph: active ingredient, strength and dosage form.
- Have the Drug Facts panel drafted and reviewed by a regulatory specialist.
- Let the manufacturer list the product under your trade name and labeler code.
- Plan stability and expiry testing with the manufacturer before the first run.
It’s a longer path than cosmetics. But each step is defined, which makes it predictable if you follow it in order.
Selling OTC products on Amazon
Amazon’s public policy pages on OTC drugs weren’t accessible to us, so check Seller Central for the current rules in your category. One documented example: Amazon staff announced that from October 16, 2024, OTC ophthalmic drug products (eye drops) must be verified through a third-party testing, inspection and certification organization. Expect documentation requests. And don’t make any claim beyond your monograph’s permitted uses, not even in images.
