Checking Medications and Substances

Checking Your Medication

Many medications available for common medical conditions, such as asthma or hayfever, may contain prohibited substances.  You need to be aware that these are readily available in products prescribed by your doctor or bought over the counter in a pharmacy.

The advice from UK Anti-Doping is simple - check every single substance or medication before you use it, even if you have used it before. It is also important to remember that medications bought abroad may contain different substances than those in the UK and you should always check before you take them.

Global DRO provides athletes and support personnel with information about the prohibited status of specific substances under the rules of sport based on the current World Anti-Doping Agency (WADA) Prohibited List, for products sold in the United Kingdom, Canada, Japan, United States, Switzerland and Australia. The system has the ability to check the status of branded medications and individual active ingredients as well as providing every search with a unique reference number for your records.

Travelling Abroad and Checking Medications

Athletes planning to travel abroad should ensure they adhere to the following advice:

  • Take enough medication to continue any treatment for the duration of the trip
  • Check the status of all products before you travel
  • Check the medication is permitted in the country of travel and whether it is permitted to bring through customs
  • Download the Clean Sport App
  • Any products purchased overseas should be carefully checked. The ingredients in common medications can and do contain different substances to those available in the UK.

Some countries have different customs laws that may prohibit the import of certain substances into a particular country. Athletes carrying a prohibited substance for a legitimate medical condition, should carry the following documents at all times:

  • The prescription from the prescribing doctor including the name of the substance, the dose and the frequency of use
  • The Therapeutic Use Exemption Certificate to demonstrate that an authorised anti-doping organisation has permitted the use of a prohibited substance for medical purposes.

Information on Supplements

UK athletes are advised to be vigilant in their choice to use any supplement. No guarantee can be given that any particular supplement is free from prohibited substances. Informed-Sport tests batches of supplements to check for contamination as part of a risk minimisation programme. Find out more about supplements
