The words licensed, off-label and unlicensed get used a great deal around prescription medicines, often without much explanation. They sound technical and a little worrying, yet they describe something routine, legal and tightly regulated. Understanding them matters more than ever as telehealth grows, because many online treatments, including compounded skincare, rely on medicines used outside the exact terms of their original licence. This article explains what each term means, how the UK, EU and USA regulate these medicines and why they are so common in skincare and dermatology.
What Does It Mean for a Medicine to Be Licensed?
A licensed medicine holds a marketing authorisation, which is the formal approval a regulator grants before a product can be sold for a particular use. Before granting it, the regulator reviews clinical trial data showing that the medicine is safe, effective and made to a consistent quality for one defined purpose. In the UK that regulator is the Medicines and Healthcare products Regulatory Agency (MHRA). The European Medicines Agency covers the EU, whilst the Food and Drug Administration covers the USA.
A licence is specific rather than open-ended. It sets out the condition the medicine treats, the dose, the route of administration and the patients it suits, and it does not extend to uses beyond those terms. Licensed medicines carry clear benefits. Regulators have tested their safety and effectiveness for the approved use, and the products come with defined dosing guidance. The authorities also keep monitoring side effects after approval. Most familiar over-the-counter and prescription products sit in this category.
What is Off-Label Prescribing?
Off-label prescribing means using a licensed medicine outside the terms of its licence. The medicine itself is fully approved, but the prescriber uses it for a different condition, dose, age group or route than the licence specifies. This happens widely across medicine, and dermatology relies on it more than most. A few everyday examples show how common it is.
- A different condition. The diuretic spironolactone, licensed for certain blood pressure and hormonal conditions, is widely used off-label for hormonal acne.
- A different concern for a skin active. Licensed for acne, tretinoin is also used off-label for skin ageing and hyperpigmentation.
- A completely new purpose. Many drugs find uses far from their first licence. The epilepsy medicine gabapentin is now prescribed off-label for chronic pain, whilst ketamine has off-label uses in depression. Botox treated eye muscle disorders long before its cosmetic use became widespread.
When a prescriber works off-label, they take on extra responsibility for the choice. Professional guidance sets out what that involves. The prescriber must be satisfied that no licensed option would meet the patient’s needs. They should rely on sound evidence or experience and keep clear records. They must also tell the patient whenever a treatment falls outside its licence.
What is an Unlicensed Medicine?
An unlicensed medicine has no marketing authorisation at all. A pharmacy prepares or supplies it for one patient’s specific needs rather than for the general market. These medicines tend to fall into a few groups.
- Specials. UK regulation calls a medicine prepared or imported to meet an individual patient’s needs a special. Specials include liquid versions of drugs that only come as tablets, along with other bespoke formulations.
- Compounded medicines. A pharmacist combines or adjusts ingredients to make a formulation at a specific strength, in a specific base or as a specific combination. This is the route behind compounded skincare, where a custom cream or serum targets one person’s skin.
- Imported medicines. Prescribers can import a medicine licensed in another country when no suitable UK-licensed version exists.
- Emerging treatments. Prescribers may use a newer medicine for a purpose it has not yet gained formal approval for. Ozempic, the semaglutide first licensed for type 2 diabetes, is a familiar example, as many doctors now prescribe it off-label for weight loss.
A medicine might end up unlicensed for several reasons. Sometimes no approved product exists in the right strength, the right combination or the right base. In other cases a patient cannot tolerate an ingredient in the licensed version. Even without a product licence, these preparations come from suitably licensed manufacturers or from pharmacy supervision, so they still meet strict quality and record-keeping standards.
How are Off-Label & Unlicensed Medicines Regulated in the UK, EU & USA?
Unlicensed medicines are still tightly regulated. The same authorities that license medicines set strict rules for prescribing, manufacturing and supplying them.
In the UK, the MHRA allows off-label and unlicensed prescribing under defined conditions. A prescriber may choose this route when no licensed alternative exists or suits the patient, or when the patient needs a different form. Strict rules still govern the manufacture and supply of specials, and a prescriber must always tell the patient when a medicine falls outside its licence and explain the benefits and risks.
Similar principles apply across the EU, where individual member states can make their own provisions for off-label or unlicensed use, particularly for rare diseases or public health emergencies. Some patients with no other options can also access experimental medicines through compassionate use schemes under strict conditions. In the USA, off-label prescribing is legal and widespread, especially in oncology, psychiatry and paediatrics. The FDA also permits use of unapproved drugs in situations such as an official shortage of a licensed product.
Why are Off-Label & Unlicensed Medicines Used in Skincare?
Several practical reasons explain why these medicines are so common in skincare and dermatology.
- No licensed product fits the concern. Many skin concerns have no single licensed product aimed precisely at them, so a tailored or off-label approach fills the gap.
- A bespoke strength or combination is needed. A compounded treatment can set a specific concentration or blend several actives in one formulation that no off-the-shelf product offers. In dermatology this helps target conditions like rosacea, acne and melasma.
- The licensed product does not suit the patient. An allergy, a sensitivity or a tolerance problem can rule out a standard formulation, so a prescriber arranges a tailored one instead.
- Personalisation improves results. Matching the active, the strength and the base to one person’s skin often works better than a one-size-fits-all product.
In each case the aim stays the same. The prescriber chooses the route that gives the patient the safest and most effective treatment for their particular skin.
Are Off-Label & Unlicensed Medicines Safe & Who is Responsible?
Used appropriately, off-label and unlicensed medicines are a well-established and safe part of care, and they carry clear lines of responsibility. The prescriber takes responsibility for the decision and for overseeing the patient’s care, and professional guidance sets out how to approach it. Good practice means using sound evidence or established experience, telling the patient when a treatment is off-label or unlicensed and keeping clear records. Regulators oversee the pharmacies that prepare these treatments, which follow strict quality standards. Anyone can report a suspected side effect through the MHRA Yellow Card scheme, which helps track safety over time.
Crucially, an off-label or unlicensed medicine can be just as safe and effective as a licensed one when a prescriber uses it appropriately. The status simply reflects the regulatory route a treatment takes. It says nothing about how well that treatment works.
How Does This Apply to Compounded Skincare?
Compounded skincare usually sits within these categories. A compounded formula is typically an unlicensed special, made to a prescription for one patient, and it often uses familiar actives off-label as well. That combination is what lets a treatment work around your skin rather than a mass market. It is the same framework that lets a prescriber choose an active like tretinoin, hydroquinone or spironolactone. A pharmacy then prepares it at the strength and in the base that suit you.
Off-label and unlicensed medicines are a long-standing, regulated part of how doctors tailor treatment when a standard licensed product does not fit. In skincare, they are what make genuinely personalised, prescription-strength treatment possible. Understanding the terms helps you see how your treatment is made and why a prescriber has chosen it.
