Re: How long after taking Synthroid do I need to wait to take Welchol?
You should take Welchol at least 4 hours after the Synthroid. It can bind up the Synth and carry it out of your body before it can be absorbed.
IMO, taking Synth with milk probably will be ok as long as you take it that way every day. The calcium in the milk might bind up some of the Synth leaving it unabsorbed, although the natural calcium in milk is probably not as binding as calcium carbonate in supplements and antacids. If you take with milk every time, you might eventually need a higher dose than you would if you took it with water, since you might not be getting the benefit of the entire dose you take. It definitely would be better to take it with water, an hour before breakfast, and 4 hours apart from calcium, iron, estrogen meds, antacids, and of course, the Welchol. There may be other meds listed on the Synth insert sheet. (If by chance they aren't, there's a comprehensive list on the Synth site.)
Hope that helped.
