Driftless SW Wisconsin | My vet tells me that pour on ivermectin works for about 45 days whiçh I believe is the withdrawal period. It is primarily for internal parasites. For longer acting version use long range.
Injectible ivermectin works better than pour on. However increasing rate of pour on doesn't lengthen the effective period.
I would stick with label rate and watch withdrawal period. Maybe use injectible rather than pour on. | |
