Before throwing away any old or expired medications you may have at home, give it some thought. According to the Central Pharmaceuticals Standard Control Organization (CDSCO), it is appropriate to flush some pharmaceuticals down the toilet in order to prevent inadvertent injury to humans or animals.
 
At least 17 medications were designated by the regulatory body as being suitable for this method of disposal. The majority of the medications on the list, according to Pharmabiz, are opioids or other illegal synthetic opioids that are used to treat anxiety, pain, and other ailments.

The list of 17 drugs includes:

Fentanyl
Fentanyl Citrate
Diazepam
Buprenorphine
Buprenorphine Hydrochloride
Morphine Sulfate
Methadone Hydrochloride
Hydromorphone Hydrochloride
Hydrocodone Bitartrate
Tapentadol
Oxycodone Hydrochloride
Oxycodone
Oxymorphone Hydrochloride
Sodium Oxybate
Tramadol
Methylphenidate
Meperidine Hydrochloride

Since some medications are thought to be especially dangerous if overused, flushing them after they expire or when they are no longer needed is safe.  The goal of the precaution is to lessen the likelihood that these medications will fall into the wrong hands or result in unintended injury.
 
According to the CDSCO, these drugs can be extremely harmful and, in some cases, fatal with a single dosage if taken by someone other than the intended recipient.
 
The drug body recommends discarding them if they are kept in storage unused, outdated, or undesired to prevent putting anyone else in the house—including pets—in danger. The government suggested that the pharmaceuticals specified by the CDSCO be flushed down because they mostly contained addictive and abuse-prone narcotics, according to Devarati Majumdar, director of Max Healthcare.

In order to lessen environmental contamination, the CDSCO offers guidance on the scientific disposal of other pharmaceuticals through "drug take-back" initiatives.  According to The Times of India, improper disposal of pharmaceuticals leads to their end up in water supplies, which subsequently promotes the development of multidrug-resistant diseases.
 
The state government can work with local organizations to create a procedure and facility for gathering and disposing of unneeded or expired medications under the Biomedical Waste Management Rules of 2016.
