I just bought Tri-Heart Plus (Ivermectin/pyrantel) from Fosters and Smith online after a lot of investigative work. I always assumed it not to be a good idea to buy medications online.
I verified with Shering-Plough (makers of Tri-Heart Plus) via e-mails and phone conversations that as long as there is an intact vet-client relationship that will provide documentation as requested they will provide the same guarantee as if it was bought in the vets office. I also verified thru Shering-Plough and Dr Fosters and Smith that the medication is bought directly from the manufacturer following all safety protocols without the use of any middle man .
My vets office was not as helpful, they charged me $9 for the script to be faxed and really wanted to charge $18 because it was actually 2 scripts due to weight of dog being over 100#'s.
They also informed me that in no way would this medication be guaranteed from the manufacturer and their rep had assured them of this as well.
Short version-after re-checking with their rep the medication is actually sold directly to Fosters and Smith. I offered to buy directly from my vets office if they would match the price of Fosters and Smith naturally they declined.
If I had the slightest doubt about the efficacy of the drug from Fosters and Smith after all the time I spent checking and cross checking I would have paid the extra money and bought from my vets office.
I can offer no advice or personal experience from any other online sites.
