UK Customs Stance
The UK is relatively open regarding personal medication. You can bring most prescription medicines provided they are for personal use.
Key Guidelines
- Quantity: The rule of thumb is a 3-month supply maximum. Anything more might be suspected as commercial import.
- Controlled Drugs: If you are carrying morphine, diazepam, or strong opioids, you strictly need a personal license if the supply is for 3 months or more. For shorter trips, a doctor's letter is usually sufficient.
- Ayurvedic Meds: Generally allowed, but ensure they do not contain endangered plant or animal species (CITES restrictions).
