Doctors Can Prescribe Unapproved Drugs — But Why?

A medicine can be approved for one condition yet prescribed for another. This is known as off-label prescribing, and it is a normal part of clinical practice in many areas of medicine. It is not automatically illegal, unsafe or inappropriate.

But an off-label prescription should not leave you unclear about why you are taking it, what benefit is expected or how its risks apply to you. Those questions become especially important after 60, when the body, health conditions and medication list may all affect how a treatment works.

What does “off-label” really mean?

A medicine’s official label reflects the purpose, dose, patient group and risks considered during its approval. Doctors may sometimes use that same medicine outside the original label—for a different symptom, dose or type of patient—when they believe it is medically appropriate.

The important distinction is not simply whether a medicine is on- or off-label. It is whether there is a clear reason for its use in your particular situation. A prescription may be intended to treat a diagnosed condition, reduce symptoms, replace an alternative that was not tolerated or address a specific risk. Those are very different circumstances from taking something because it is popular or marketed as part of “healthy ageing.”

Why age and context can change the decision

Medication effects do not stay fixed throughout life. Kidney and liver function, body composition, hydration, blood pressure, balance, memory and frailty can all influence how a medicine behaves. Other prescriptions, over-the-counter products and supplements can add another layer of complexity.

That means a medicine that seems straightforward on paper may require more individual consideration later in life. Symptoms such as dizziness, fatigue, confusion, muscle pain or sleepiness can sometimes be mistaken for ordinary ageing when medicines or interactions may be contributing.

Evidence, monitoring and the wider care plan

A key issue with off-label use is whether the available evidence fits the person receiving the prescription. Research in younger adults, animal studies or early research may not answer the same questions for an older person with multiple health conditions or medicines.

The video also explores why a prescription is not a complete care plan. Good prescribing involves a defined goal, awareness of possible side effects and interactions, and a point at which treatment is reviewed. This matters particularly when medicines are obtained through convenient online services that may not have the full picture of a person’s health history or medication list.

Watch the video for the three questions to ask

Off-label prescribing can be thoughtful and reasonable when it is supported by evidence, careful clinical judgment and appropriate follow-up. It can also become less reassuring when explanations are vague, claims are stronger than the evidence or no review plan exists.

In the video, Dr Deepa explains the three practical questions that can help adults over 60 have a clearer conversation with their doctor or pharmacist before starting or continuing an off-label medicine. Do not stop an important prescribed medicine without professional advice, as some medicines need to be reduced gradually.
