Hair Loss Hair loss: side effect of Ivermectin?

[savannahsatchel]

Has anyone had side effects of piggies losing hair behind their ears where Ivermectin was placed? On all 5 of the piggies I used Ivermectin on, they have bald patches behind their ears. Calling the vet to set up an appointment now. Any advice would be appreciated. Thank you.

All guinea pigs have bald patches behind their ears.

It doesn't usually cause hair loss. What strength of ivermectin did you use? How much did you apply?

These patches just seem very large to me, like something may be wrong. And I used Ivermectin pour-on for catrle, 5mg/ml.

According to guinealynx, it was two drops behind each ear according to their weights.
