Is there any data or advice on using teriparatide after romosozumab for treatment of postmenopausal osteoporosis?  

64F with osteoporosis treated with Risedronate for 5 years.  Despite that treatment her T score at the lumbar spine dropped from -3.0 to -3.6.  She has never sustained an osteoporotic fracture.  She is very physically active and consumes an adequate amount of calcium and vitamin D and her lab work was unrevealing for secondary causes.  She is interested in using an anabolic, and it seems that using Romosozumab after the bisphosphonate may be better than Teriparatide.  The question is, will it be helpful to take Teriparatide after she has completed the year of Romosozumab?  I am posting this question since we do not want to use Teriparatide after Denosumab and want to make sure I'm not missing something with Romosozumab. Thanks.
