After a lot of hemming and hawwing, I've decided to start using Ivermectin as a HW preventative for Gypsy instead of the Heartgard she has been on. Just for a little background history, she had demodex when she was young, so she was treated with ivermectin daily and at a MUCH higher dose than I would be using now. I realize now that there are better ways to treat demodex, but at the time I was like 13 and just following instructions...but that's kinda beside the point! So anyway, given her history and the fact that she never reacted to the Ivermectin before, I am relatively certain the switch should not be a problem. (Feel free to offer arguments if my reasoning isn't sound).
Now here's the real reason for my post. I went to the feed store looking for Ivomec, but it seems they were out of stock. Instead I found "Noromectin (ivermectin) 1% injection for cattle and swine." It contains 1% ivermectin, 40% glycerol formal, and propylene glycol q.s. ad 100%. It gives the same recommended dose for cattle and swine as Ivomec does. So it seems to me that it is basically the same thing as Ivomec, just a different brand name, perhaps? It's made in the UK.
Has anyone heard of Noromectin before? More importantly, could anyone possibly tell me if there is any reason why Ivomec would be considered preferable? Or are they more-or-less equivalent/substitutes? Thanks in advance. :-)
