Disposal instructions on the label are part of FDA's "risk mitigation" strategy, says Capt. Jim Hunter, R.Ph., M.P.H., senior program manager on FDA's Controlled Substance Staff. When a drug contains instructions to flush it down the toilet, he says, it's because FDA, working with the manufacturer, has determined this method to be the most appropriate route of disposal that presents the least risk to safety.
Drugs such as powerful narcotic pain relievers and other controlled substances carry instructions for flushing to reduce the danger of unintentional use or overdose and illegal abuse.
For example, the fentanyl patch, an adhesive patch that delivers a potent pain medicine through the skin, comes with instructions to flush used or leftover patches. Too much fentanyl can cause severe breathing problems and lead to death in babies, children, pets, and even adults, especially those who have not been prescribed the drug. "Even after a patch is used, a lot of the drug remains in the patch," says Hunter, "so you wouldn't want to throw something in the trash that contains a powerful and potentially dangerous narcotic that could harm others."
Despite the safety reasons for flushing drugs, some people are questioning the practice because of concerns about trace levels of drug residues found in surface water, such as rivers and lakes, and in some community drinking water supplies. However, the main way drug residues enter water systems is by people taking medications and then naturally passing them through their bodies, says Raanan Bloom, Ph.D., an environmental assessment expert in FDA's Center for Drug Evaluation and Research. "Most drugs are not completely absorbed or metabolized by the body, and enter the environment after passing through waste water treatment plants." end of quote

Belive it or not sewage goes through that many different treatment processes itself breaks down alot of the stuff in the water anyway,one of the few it can't is hormones that people taken for hrt or the pill,those do build up in the water system and can't be broken down and affect the growth an reproduction of fish and othere aquatics.But the main contributor to build up of chemicals are businesses who release their waste effluent of manufacturing processes into waterways that don't go through the wastewater treatment process and run directly out to sea untreated.
Business waste=dollars=allow thousands of litres of waste everyyear into the sea untreated ..so afew pils to the FDA is a grain of salt in the sea i would think which might explain their blaseness

my vet used to take back an refund for tablets that weren't used as long as they were still in the blister pack they could use them,but opened liquids degrade once opened and like another poster said,they can't be sure what's in the open bottle,But any lotions like ear lotions or skin lotions I use to take mine to the petaid hospital,they would use them in the past but I' not so sure now because they use to re-use the child friendly containers an i use to collect them from people an donate them but they stopped doing that because they couldn't sterilise the bottles sufficiently to make sure there were'nt and drug residues.
Ecologically speakin the best way to make use of the drugs would be to use them for what they were intended,if nobody wants to use them for that then I would return them to the vet and get a refund on the unopened ones..
