**Note: not for the faint of heart**
From the instruction pamphlet:
"Therapeutic indications: Vermox is indicated for the treatment of single or mixed infestations by Enterobius vermicularis (pinworm), Trichuris trichiura (whipworm), Ascaris lumbricoides (large round-worm), Ancylostoma duodenale, Nector americanus (hookworm), Strongyloides stercoralis (threadworm), Taenia spp. (tapeworm)
Undesirable effects: Adverse reactions to Vermox have been minor in most cases. Transient abdominal pain and diarrhea have only occasionally been reported, in cases of massive infestation and expulsion of worms"
I guess I had a massive infestation. Shudder
