I tried 0.5mL of moxidectin injection (Cydectin® Injectable)on my stomach today. I have to say it also hurts although it claims to be not irritate at the site of injection. It may hurt less than the ivermectin, but still hurts and developed a hard bump there. The only painless injection so far I found is doramectin.
The upset stomach sign also show up later by stimulating the acid production.
My eye feel a little better after the injection.
However I am not sure about how to compare the benifit of the injection of moxidectin over the oral moxidectin, since the oral moxidectin actually works.
