The timeline for the study was as follows: (1) 0 months: baseline taking levothyroxine, add calcium at visit; (2) 2 months: visit No. 1 taking levothyroxine plus calcium; (3) 3 months: visit No. 2 taking levothyroxine plus calcium, discontinue calcium at visit; and (4) 5 months: final visit taking levothyroxine, after calcium discontinuation.

Applies to: levothyroxine and Pepcid Complete (calcium carbonate / famotidine / magnesium hydroxide) Using calcium carbonate together with levothyroxine may decrease the effects of levothyroxine. You should separate the administration of levothyroxine and calcium carbonate by at least 4 hours.
Supplements that can stop the absorption of levothyroxine. Calcium. Some calcium-rich foods and supplements interfere with levothyroxine
Applies to: Synthroid (levothyroxine) and Tums Ultra 1000 (calcium carbonate) Using calcium carbonate together with levothyroxine may decrease the effects of levothyroxine. You should separate the administration of levothyroxine and calcium carbonate by at least 4 hours.

I do not drink alcoholic drinks I am drinking milk this time (did I make mistakes for much lactose, calcium and protein?) I prefer milk to beer...........
