Forteo And Its Similars

Hello,

Has anyone been on teriparatide therapy?
I am 58 years old and my doctor insists that I start some cure similar to Forteo (I can't remember the exact name now), but I have never been really friendly towards medicines and drugs. Once I ended up at CityMd because of half a pill of Tylenol...
Either my body is very sensitive or I am an irrecoverable hypochondriac.
I am terrified about the possible side effects.

Thank you,
Renata
