Yes, hormone replacement therapy (HRT) can be taken with Forteo (teriparatide). Indeed, studies indicate that combining them may lead to greater increases in bone mineral density (BMD) compared to using either treatment alone. Combining these treatments acts on bone formation (Forteo) and resorption (HRT), showing significant improvements in spinal and hip bone density.

"Conclusions: Adding teriparatide, a bone formation agent, to HRT, an antiresorptive agent, provides additional increases in BMD beyond that provided by HRT alone. The adverse effects of teriparatide when added to HRT were similar to the adverse effects described for teriparatide administered alone. Whether teriparatide was initiated at the same time as HRT or after at least 1 year on HRT, the incremental increases over HRT alone were similar."
Let me suggest that you do some research about the safest way to use HRT. The research will show over and over that BHRT topical, vaginal, non oral are the safest ways to use hormones.
