To all:
With the O.K. of my vet, I have been dosing my ferrets and dogs with
ivermectin for the past two years.  I purchase the sterile 50 ml 1%
solution at a general feeds store and dilute a quantity each month.
Does anyone have any idea if diluted (with propylene glycol) ivermectin
has a different shelf life than undiluted, given light-free storage?
In addition to being convenient, this method is VERY cheap--about .15
a month for all.  Just MAKE SURE that you are very careful about
diluting and dosing for your animals.  I do it because I work in a laboratory
and have access to syringes and other instruments for precise measurement.
One millileter of undiluted 1% ivermectin contains 10,000 micrograms!
I dilute 1:99 with propylene glycol.  Any thoughts?
 
Amy
