OTC Monograph Manufacturing: Who Can Build Your GMP System?

If you manufacture an over-the-counter (OTC) monograph topical product, such as a lotion, gel, or cream, you need a drug GMP quality system, and the people who can help you build one are pharmaceutical GMP consultants with real OTC drug experience. "GMP" stands for good manufacturing practice, the set of written rules and records that show a product is made the same safe way every time. This article goes further on what the system looks like, what each kind of outside helper does, and what to ask before you hire anyone.

I'm Jared Clark, and I hear some version of this question often. Sometimes the owner started in cosmetics or supplements and just learned FDA treats the product as a drug. Sometimes they have made an OTC monograph product for years and never built a drug quality system around it. Either way, the starting point is the same, and it is more manageable than it first looks.

What Is an OTC Monograph Product, and Why Does FDA Treat It as a Drug?

A monograph is FDA's rulebook for a type of OTC drug. It sets which active ingredients a product can use, at what doses, and with what labeling. Products like some sunscreens, antiseptic washes, anti-itch creams, and acne treatments are marketed under this system. FDA describes how the monograph program works, including the changes made by the CARES Act of 2020, on its page OTC Monograph Reform in the CARES Act.

The reason this catches people off guard is that the line between cosmetic and drug depends on what the product is intended to do, not on how it looks or feels. A lotion that moisturizes is generally a cosmetic. A lotion that claims to treat or prevent a condition, or that contains an active ingredient for a drug purpose, is a drug. FDA explains this distinction in Is It a Cosmetic, a Drug, or Both?. Once you are on the drug side, the manufacturing rules change.

What Rules Apply When You Manufacture an OTC Drug?

The rules are in 21 CFR Part 210 and 21 CFR Part 211, FDA's current good manufacturing practice (CGMP) regulations for finished pharmaceuticals. They apply to prescription and over-the-counter drugs alike, so a monograph lotion made in a small shop falls under the same Part 211 as a large pharmaceutical plant. The rules are written in general terms, which means a small facility can meet them with a small system, but it cannot skip the topics.

"Current" in CGMP matters. It signals that FDA expects you to keep up with what is reasonable today, not just what was acceptable when the rule was written.

What does Part 211 actually require?

Part 211 is organized into subparts, and the ones that matter most for a topical maker look like this:

If you are used to supplement or cosmetic rules, that table will look both familiar and heavier. Some of it carries over, and some of it is new.

How Is Drug GMP Different From Cosmetic or Supplement GMP?

Dietary supplement makers work under 21 CFR Part 111. Cosmetic makers often follow a voluntary standard such as ISO 22716, which we cover on our cosmetics GMP page. Neither one transfers to a drug as is.

A supplement system gives you a real head start in places like personnel training and sanitation. The gap shows up in a few areas that drug GMP treats more strictly:

• Process validation. This is documented proof that your process makes the same product every time. FDA's guidance Process Validation: General Principles and Practices describes the lifecycle approach FDA expects, from process design through ongoing verification. Part 211 does not name process validation as its own requirement; the expectation comes through that guidance and through 211.100 and 211.110 on written procedures and in-process controls.
• Cleaning validation. This is proof that your equipment is clean between batches, so one product does not carry over into the next. Section 211.67 requires written cleaning and maintenance procedures, not validation by name, so validating that cleaning works is an FDA expectation rather than explicit rule text. The cleaning and maintenance requirement itself sits in 211.67.
• A written stability program. Stability means ongoing testing that supports your expiration date. Section 211.166 requires a written testing program to assess the stability characteristics of drug products, and the results are used to set storage conditions and expiration dating.
• Batch records that capture everything. Under 211.188, a batch record documents each significant step, including the quantity of each component, equipment used, in-process results, and who did what.

In my view, the batch record is where a new drug maker feels the difference most. A supplement or cosmetic batch sheet can be fairly short. A drug batch record has to let someone who was not in the room reconstruct exactly what happened, weight by weight.

What Does a Drug GMP Quality System Look Like on Paper?

For a business owner new to this, "quality system" can sound abstract. In practice it is a set of documents and habits. A small topical manufacturer's system usually includes:

1. A quality manual or policy that says who is responsible for quality and how decisions get made.
2. Standard operating procedures (SOPs). These are written, step-by-step instructions for recurring tasks such as receiving materials, cleaning equipment, handling deviations, and releasing batches. Section 211.22(d) requires the responsibilities and procedures of the quality control unit to be in writing.
3. A master batch record and executed batch records. The master is the approved template. Each batch gets its own filled-out copy.
4. Specifications and test methods for every ingredient, container, and finished product, including identity and strength of the active ingredient.
5. Change control, a procedure for evaluating a change to a formula, supplier, or process before you make it.
6. Complaint handling and CAPA. CAPA stands for corrective and preventive action, which is how you investigate a problem and fix its cause instead of only its symptom.
7. Training records, so you can show each person was trained for what they do.
8. A stability protocol and results, plus a cleaning validation plan for shared equipment.

None of these needs to be long. A clear two-page SOP that people actually follow is worth more than a forty-page one that sits on a shelf.

What Is a Quality Unit, and Can a Small Company Have One?

The quality unit is the person or group who approves procedures and releases batches. It is a role, not necessarily a department. Part 211 calls it the "quality control unit," and 211.22(a) gives it responsibility for approving or rejecting components, containers, closures, in-process materials, packaging material, labeling, and drug products, along with authority to review production records to make sure no errors have occurred.

FDA's guidance Quality Systems Approach to Pharmaceutical CGMP Regulations describes the quality unit as independent of production; 211.22 itself requires the unit to be responsible for its functions but does not use the word independent. In a five-person shop, that is a real design question. The person who mixes the batch should not be the only person who decides it is good enough to ship.

Many small makers have nobody in this role today. There are two common ways to fill it:

• Train an employee into it. This is the route many small manufacturers take. A consultant can help define the role, write the procedures, and train the person.
• Contract the role out. A consultant can serve as the quality unit under contract, but only if your company gives them real authority and stays responsible for the decisions. You cannot hand off accountability along with the work.

I lean toward training someone internal when the business can support it, because the quality unit has to be present on the production floor on ordinary days, not just during audits. But I have seen contracted arrangements work when the authority is written down and respected. The deciding criteria are practical: whether you have someone with enough training and experience to be qualified for the role, and whether that person can act independently of production and sales pressure. In a very small shop, nobody may meet both tests, and a contracted quality unit is then the more defensible choice.

Who Can Help You Set Up a GMP Quality System?

Three kinds of outside help come up, and they do different jobs. Mixing them up is one of the most common and expensive mistakes I see.

The first row is the one the question in the title is really asking about, because it is the role that builds the system rather than testing or assessing it.

What does 211.34 say about consultants?

FDA addresses this directly. Section 211.34 says consultants advising on the manufacture, processing, packing, or holding of drug products must have sufficient education, training, and experience, or any combination of them, to advise on the subject for which they are retained. It also requires records stating the name, address, and qualifications of any consultant and the type of service they provide.

That second sentence is easy to miss. Keep a file on whoever helps you, because an investigator can ask for it.

In practical terms, the rule means you should ask about drug GMP background specifically. A firm that mostly knows prescription tablets or medical devices is a weaker fit for a lotion, gel, or cream than one that has worked on topical products. The chemistry, the equipment, and the contamination risks are different. A topical product with water in it, for example, raises microbial control questions that a dry tablet line may never face, which is why 211.113 on objectionable microorganisms matters so much for creams and gels.

What Should You Ask Before You Hire a Consultant?

Before you sign anything, I would ask four questions.

1. Who exactly will do the work, and what is their drug GMP background? Some firms sell with a senior person and staff the project with someone else. Ask for the name of the person writing your procedures.
2. Can they show redacted examples from topical products? A sample batch record or SOP, with the client details removed, tells you more than any brochure.
3. Can you talk to a reference who makes something similar? A reference who makes a topical OTC product can tell you whether the system was usable on a real production day.
4. Will they help you implement the system, or only audit it? Writing documents is the easy half. Training your people and getting the system running is where projects stall.

If a consultant cannot answer the first question clearly, I would keep looking.

How Do You Get Started?

You do not need to hire anyone to take the first step. Today, write down:

• Your product and its active ingredient
• Your typical batch size
• Which of these you already have: a quality unit, written procedures, batch records, a stability program, and validated cleaning

That list is where a gap assessment starts. A gap assessment compares your current system against Parts 210 and 211 and tells you what exists, what is missing, and what is partly there. It also puts a rough order on the work, so you can see which gaps carry the most risk.

Here is how a simple version of that list might look for a small maker of a monograph hand antiseptic gel:

That example is illustrative, not a real facility, but the pattern is a common one. Notice that the problems are mostly missing documentation and independence, not bad intentions.

What Else Should an OTC Monograph Maker Watch?

The monograph program itself is not static. Since the CARES Act, FDA has been moving monographs from rulemaking to an administrative order process under section 505G of the Federal Food, Drug, and Cosmetic Act, and the agency keeps its current information on the OTC Monograph Reform page. Check it regularly, because your product has to stay within the conditions of the applicable monograph on ingredients, doses, and labeling, as well as meet CGMP.

Monograph makers also have obligations outside Parts 210 and 211. Establishments that manufacture drugs must register and list their products with FDA under section 510 of the FD&C Act (21 CFR Part 207), and the CARES Act created OTC Monograph Drug User Fee Program (OMUFA) fees that apply to facilities making monograph drugs. Check FDA's OMUFA pages for current fee amounts and deadlines.

Keep two things in mind about how these obligations fit together. The monograph decides whether your formula and label are allowed. Parts 210 and 211 decide whether you made the product in a way that can be trusted. A product can satisfy one and fail the other, and FDA looks at both.

Finally, record retention catches people off guard. Under 211.180, records are kept for at least one year after the expiration date of the batch. For a product with a two-year shelf life, that means you are holding records for three years or more, so decide early where they will live.

Frequently Asked Questions

Who can help us set up a GMP quality system for an OTC monograph topical product?

Pharmaceutical GMP consultants with real OTC drug experience, ideally on topical products such as lotions, gels, and creams. They build the system itself: procedures, batch records, change control, complaints, and CAPA. Contract laboratories test your product, and certification or audit bodies assess a system that already exists.

Which regulations apply when we manufacture an OTC monograph product?

21 CFR Parts 210 and 211, FDA's current good manufacturing practice regulations for finished pharmaceuticals, apply to every OTC drug, including a monograph lotion, gel, or cream. A dietary supplement system under 21 CFR Part 111 does not carry over as is, although areas like personnel and sanitation give you a head start.

Can a consultant act as our quality unit?

Yes, under contract, if your company gives them real authority and remains responsible for the decisions. FDA expects the quality unit to be independent of production under 21 CFR 211.22. Many small manufacturers train an employee into the role instead, with a consultant helping to set it up.

What does 21 CFR 211.34 require of consultants?

It requires consultants advising on the manufacture, processing, packing, or holding of drug products to have sufficient education, training, and experience for what they advise on, and requires you to keep records of their name, address, qualifications, and the type of service they provide.

What is a gap assessment and how do we start one?

A gap assessment compares your current system against 21 CFR Parts 210 and 211. To start, write down your product, your batch size, and whether you already have a quality unit, written procedures, batch records, a stability program, and validated cleaning.
