Yes, I'm parasite free & still take a weekly maintenance dose of ivermectin to keep any remaining encysted parasites sterile & prevent reinfection.
The protocol recommends Ivermectin be taken for 5 or more weeks or until infection is cured. Since each person's case varies in severity of infection, you can stop it earlier or take it longer, as needed.
"Ivermectin (Stromectol):1 dose*, based on .2mg/kg, 1 hr before bedtime, on empty stomach, with 8oz water or beverage. Take dose for 4 days on, 3 days off. Repeat dosage every week (even during off-days of Albendazole) for 5 or more weeks, as needed, to cure infection.
Alternate Dosage Schedule: For severe hyperinfection cases, follow this schedule instead of the above: Take dose for 7 days on, 2 days off, 2 days on. Continue the "pulse method" of 2 days off, 2 days on, etc, even during off-days of Albendazole, until infection is cured."
