Some VA hospitals take and dispose of drugs. The La Jolla VA has a receptacle near its entrance. You may check if there is a VA near you that will take them.

If I were in this situation, I would contact thee local POTW (sewer authority) and ask. If they say NO, nothing is lost. If they say YES, you win.

Hi Jennifer,

I've recently done a lot of research into antibiotic disposal. There are some antibiotics that will breakdown in an autoclave, but most don't which is why they should be discarded as hazardous waste and incinerated. There really aren't any other effective options I've found.

All,

 

The NIH Drain Disposal guide came across my email recently, and it has left us with a question specifically about kanamycin.  https://nems.nih.gov/Documents/NIH_Drain_Discharge_Guide.pdf

 

One of our researchers uses kanamycin in their antibiotic resistance studies.  The total amount used over 10 weeks is about 100mg and would never exceed 200mg.  They are working with microgram quantities on a weekly basis. 

 

The NIH Drain Disposal guide suggests kanamycin should be treated as hazardous waste (collected and sent to disposal) Is anyone familiar with alternative disposal for kanamycin?  Our concern is the very small amount of kanamycin in the large amount of water and bleach would have a drastic effect on our waste stream. 

 

Is bleach sufficient to render the kanamycin appropriate for drain disposal?  I have also seen suggestions that kanamycin be treated with acid to render it inactive and thus okay for drain disposal; but then wonder would neutralizing the acid (to make that appropriate for drain disposal) nullify the acid inactivation? 

 

We do have access to an autoclave, but the NIH guide seems to suggest heat does not render kanamycin safe for the drain. 

 

Your thoughts are appreciated,

Jennifer.
