Safety concerns associated with temporary interruption or abrupt discontinuation of Forteo therapy have not been identified

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).

Inform your physician if you had to stop teriparatide for any period of time.
