So a 180 pound person would take 180/1250 of the tube - .144 of the tube, which is about 1/7th. To figure out what fraction .144 is of the full tube, you have to do a bit more math, but it’s easy math - divide 1 by whatever decimal (.144) you come up with. The answer is the number of doses in a full tube of ivermectin, in this case, 6.9 or 7. Round up, since it can’t hurt you.

Good thanx, is that a 18mg dose and how often?
