FAQs
What’s the difference between prescription and over-the-counter melatonin in the UK?
In the UK, prescription melatonin is classified as a medicine, meaning you can only get it through a healthcare professional. It’s carefully regulated and usually prescribed for more serious conditions like chronic jet lag or severe sleep disorders. This regulation ensures that the product adheres to strict standards for safety, quality, and dosage.
Meanwhile, over-the-counter melatonin is sold as a supplement and is often used for milder issues, such as occasional jet lag or slight sleep troubles. However, it’s less tightly controlled, so dosages and formulations can differ between brands, which might lead to inconsistencies in effectiveness.
Whether you opt for prescription or over-the-counter melatonin will depend on your situation. If you’re dealing with persistent or more serious sleep problems, it’s always a good idea to seek advice from a healthcare professional.
What is the process for getting a prescription for melatonin in the UK?
In the UK, melatonin is available only with a prescription, so you’ll need to consult a healthcare professional to access it. This usually involves visiting your GP or using an online doctor service, where your medical history and sleep issues will be reviewed to decide if melatonin is the right option for you.
Once prescribed, you can obtain melatonin from a registered pharmacy or a licensed online provider. Keep in mind that from 2025, using melatonin without a prescription will not be legally permitted in the UK. Always rely on professional guidance to use it safely and effectively.
Are there any legal requirements to consider when buying melatonin from abroad in the UK?
In the UK, melatonin is classified as a prescription-only medicine, meaning you can only legally obtain it with a prescription from a licensed healthcare professional. While it's generally permissible to import melatonin for personal use, selling or distributing it without proper authorisation is against the law.
If you decide to purchase melatonin from an international supplier, ensure it’s strictly for personal use and that the supplier adheres to UK regulations. Commercial importation or resale requires specific licensing, so it’s crucial to understand the legal requirements beforehand. If you're unsure about the safe or legal use of melatonin, always consult a healthcare professional.
