Carol,
Tom had EDTA chelation twice a week for 12 weeks before the doctor
visit that showed no blockage. After that he went to one per week
and is now taking one per month. Later he will go on a maintenance
program of one or two IV chelations twice a year or as needed.
EDTA chelation is given as an IV drip and is used to open blocked
arteries. It costs about $100 for each IV treatment which take 3 to
4 hours each. It usually takes 20 to 30 treatments to open clogged
arteries.
DMSA cheltion targets lead and mercury and is given in capsule form.
Some doctors recommend one capsule every 4 hours for a week, then
skip a week, and so on.
