Facts about Intrinsa

What these facts mean

Controlled drug?
Yes, Schedule 4 of the Misuse of Drugs Regulations?
  • Controlled drugs are medicines that UK law controls more strictly because they can be misused or cause dependence. The Misuse of Drugs Regulations 2001 divide them into 5 schedules: schedule 1 has the strictest rules and schedule 5 the least strict.
  • Schedule 4 has lighter rules. Its part II covers anabolic steroids and hormones such as growth hormone.
  • A prescription is valid for 28 days and usually covers up to 30 days of treatment.
  • Travelling abroad: carry it in your hand luggage, take your prescription or a letter from your doctor to show it is yours, and check the rules of the country you are going to with its embassy before you travel (GOV.UK).
