Guidance

Decide if your product is a medicine or a medical device

How the Medicines and Healthcare products Regulatory Agency (MHRA) makes decisions on what is a medicine or medical device (borderline products).

This guidance was withdrawn on

Overview

Some products are hard to distinguish from a medicine or a medical device, for example cosmetics, food supplements or biocidal products. These products are called borderline products until their status has been decided.

The MHRA determines whether a product falls within the definition of a medicine – ‘medicinal product’ or a medical device and provides information on whether a product is a medicine or a medical device or not.

Types of borderline products

The types of products which may fall in to the borderline category include:

  • cosmetics
  • food products, including, in particular, food supplements
  • herbal products
  • medical devices
  • biocides
  • machinery/laboratory equipment

There is also a borderline between medicinal products and medical devices. In these cases it will be the claims being made and the mode of action that will decide which regulatory regime will apply.

Borderline medicines

A medicinal product is:

  • any substance or combination of substances presented as having properties of preventing or treating disease in human beings
  • any substance or combination of substances that may be used by or administered to human beings with a view to restoring, correcting or modifying a physiological function by exerting a pharmacological, immunological or metabolic action, or making a medical diagnosis

You can find more detailed information in Regulation 2 of the Human Medicines Regulations.

Food supplements that contain familiar substances like vitamins, amino acids or minerals are generally subject to food safety and food labelling legislation rather than medicines control. You can get advice on food and cosmetics from the Trading Standards Institute.

The MHRA decides whether the claims that are made or the active substance(s) present would mean that the product is regarded to be a medicinal product.

The inclusion of herbal or ‘natural’ ingredients does not exclude a product from being a medicinal product. The MHRA takes the same factors into account when deciding the status of a product with herbal ingredients.

How we decide if a product is a medicine

MHRA decides whether a product is a medicine when:

  • the manufacturer is not sure if their product is a medicine or not, and they come to the MHRA for advice
  • The MHRA receives a complaint that a product is being marketed as a medicine but does not have a marketing authorisation (formerly a product licence)

We look at:

  • the claims about what the product does (explicit and implicit)
  • the pharmacological, metabolic or immunological properties of the ingredients (this includes any herbal ingredients)
  • the primary intended purpose of the product
  • whether there are any similar licensed or registered products on the market
  • how it is presented to the public through labelling, packaging, promotional literature and advertisements

Complaints

All referrals and complaints about potential breaches of The Human Medicines Regulations 2012 are reviewed and dealt with by the MHRA. As we receive a high volume of referrals, it is necessary to consider them on the basis of priority, the highest of which is where there is a perceivable risk to the health and safety of consumers. As a consequence, it is not possible to take immediate action in all cases.

In the majority of cases we aim to resolve issues through voluntary compliance by the relevant company. It cannot be assumed that a product found to be in breach of medicines regulations will always be removed from sale as a result of our action. In some cases, issues can be resolved by amending product details such as claims or product formulations.

Generally, investigations need to be conducted with commercial confidentiality in mind and for that reason, it is not always possible for us to provide feedback on cases. It is also not possible to say how long investigations will take to reach a conclusion as this is dependent on a number of factors, several of which can delay progress. This will apply in particular where voluntary compliance is not achieved, or where investigations need to be escalated to a position of potential prosecution. Although it may appear that nothing is being done, this is not the case. In such circumstances, there is a risk that cases could be prejudiced by disclosures.

In some instances, the MHRA receives referrals about products that are not deemed to be in breach of medicines regulations, or which may be more appropriately dealt with by another authority such as Trading Standards. This may be where more than one set of regulations is being breached. We will either recommend the referrer contacts the appropriate authority themselves, or in some circumstances, may forward the complaint on their behalf. The MHRA will not be able to chase up referrals on behalf of a third party where they have been forwarded to another authority.

The MHRA has authority to administer and enforce regulations relating to medicinal products that are sold, supplied or advertised from within the UK. Products that are sold, supplied or advertised by non-UK companies from outside of the UK and exported directly to consumers in the UK are investigated, but may fall outside of the MHRA’s legal jurisdiction.

Borderline medical devices

Medical devices fall into 1 of 3 categories, as each type is governed by a different EU directive:

The MHRA can give advice if you are not sure which category your device fits into.

You should not assume that if your product is considered a medical device in countries outside the EU that it will be a medical device in the EU as well.

Decisions about whether a product is a medical device are based on the stated intended purpose of the product and its mode of action.

If the product is a medical device, the principal intended action is fulfilled by physical means.

Getting advice about your product

Borderline medicines

You can find detailed advice here in our a guide to what is a medicinal product (PDF, 991 KB, 71 pages). You should read this document before contacting the MHRA.

You can obtain a regulatory opinion on the status of a product you are planning to sell in the UK by providing the appropriate details using the Medicines Borderline Advice Form. The MHRA will only respond to a maximum of 4 product enquiries at a time.

Borderline medical devices

If your enquiry is about the regulatory route for a medical device you should email Devices.regulatory@mhra.gov.uk.
