Unneeded medications should be disposed of in special ways to ensure that pets, children, and other people cannot consume them. However, you should not flush this medication down the toilet. Instead, the best way to dispose of your medication is through a medicine take-back program. Talk to your pharmacist or contact your local garbage/recycling department to learn about take-back programs in your community. See the FDA's Safe Disposal of Medicines website ( http:///c4Rm4p ) for more information if you do not have access to a take-back program.
Some side topics mentioned above: about liver protection, it's partially correct: supplements such as milk thistle extract or N-acetylcysteine were shown to protect liver from chemical damage ie acetaminophane, but the mechanism is different from 17aa steroid caused liver damage. There is no evidence that it can help steroid users. There are conpounds that can help for steroid caused liver problem though, for example Ursodeoxy-Chloric Acid. It was used by doctors to reverse 17aa steroid caused cholestasis (bile stay in the liver)... not sure if it can 'prevent' the problem, theoritically possible.
