Thank you Chris. Here's what my doctor wrote back to me:
"You may hold the Forteo for the trip and resume when you return." Then she also included this package insert info:
"Lilly has not identified any safety concerns, including adverse reactions or side effects, associated with temporary interruption or withdrawal of Forteo® (teriparatide [rDNA origin] injection) therapy during our clinical studies or follow-up analyses (Neer, 2001; Orwoll, 2003; Lindsay, 2004; Saag, 2007; Saag 2009; Silverman, 2013).
It is not known how stopping and starting teriparatide effects how it works as teriparatide was studied as a once daily injection without interruptions for 24 months (Forteo Package Insert, 2012)."
