The advice is simple - check every single substance or medication before you use it - even if it’s a medication you have used and checked before.

When checking your medication, make sure you:

• Check the status of all the active ingredients listed on the ingredients label of your medication
  
  
• If using the Drug Information Database (www.didglobal.com), check that the ingredients listed on the response page match the substances listed on the label of your product
  
  
• Check the correct ‘route of administration’

For any specific regulations for a substance in your sport check your sport’s Anti-Doping Regulations.
