Can I use safeguard goat dewormer to deworm my rabbit with pinworms??

Hey! I just found pinworms in Milo’s poop a few days ago. I haven’t seen any since, but would like to deworm him to be sure. We have on hand safeguard goat dewormer. Can I do 20mg? I don’t have a vet so I am making sure I don’t overdose.
