hi tkdesign, Tymlos doesn't cause gerd or stomach pain. Hypercalcemia can cause nausea. Tymlos raises your serum calcium for about four hours. Be well hydrated before your injection. Have something salty and/or something with caffeine to avoid any headache from low blood pressure.
Which leads to your other question about calcium. I'm not on your medication, but the similar Forteo. I've never had nausea but I'm stingy with calcium supplementation.
I take citrical usually 250mg in the morning. After two years on Forteo my calcium was down 9,1 from 9.8 so I added 250mg at night. It easy to figure out how much we absorb from food. But we try to add it all up. Usually 1200mg of Calcium in total is recommended. The endocrine society recommends 1000 to 1200 daily total including dietary calcium Your doctor is recommending supplement because your serum labs are low?
Tymlos is such a good medication. I hope it works well for you.
