I do not know. Its new to me. I would like to know about its answer.

Thanks for nice query@ Jagmohan Sharma

The best is to return it to the pharmacy or close by hospital for disposal.

We return it to the Pharmacy or bury it in the soil.

In most countries the expired medicine was thrown in garbage and then burn to protect environment from contamination.

In the USA, you simply throw it in the garbage and it ends up in a landfill. If it is toxic, then you contact the appropriate authority.

Some medicines come with disposal instructions. If you received disposal instructions for a medicine, you should dispose of that medicine as directed by those instructions. Otherwise, if your medicine is on the list of medicines recommended for flushing, and you did not receive information containing disposal instructions along with your prescription, you should dispose of any used or unneeded medicine by flushing it down the toilet if a take-back option is not readily available.
