I recently read this article http://www.abc.net.au/local/stories/2011/06/24/3252657.htm
about using a pill containing Ivermectin to treat children for head lice.  I looked into it and this is what I found.

As a parent I am not completely comfortable taking this route.  However panicked I may be about head lice I know there are other solutions available.  Read my free head lice help kit if you want to know about those options.  I won’t be selling a pill for head lice unless allot more goes into proving its safe and effective long term.
