6.1 Clinical Trials Experience Because clinical trials are conducted under widely varying conditions, adverse reaction rates observed in the clinical studies of a drug cannot be directly compared to rates in the clinical trials of another drug and may not reflect the rates observed in practice.
In the two clinical trials with Medroxyprogesterone acetate, over 3,900 women, who were treated for up to 7 years, reported the following adverse reactions, which may or may not be related to the use of Medroxyprogesterone acetate.
The population studied ranges in age from 15 to 51 years, of which 46% were White, 50% Non-White, and 4.9% Unknown race.
The patients received 150 mg Medroxyprogesterone acetate every 3-months (90 days).
The median study duration was 13 months with a range of 1–84 months.
Fifty eight percent of patients remained in the study after 13 months and 34% after 24 months.

Because these reactions are reported voluntarily from a population of uncertain size, it is not always possible to reliably estimate their frequency or establish a causal relationship to drug exposure.
There have been cases of osteoporosis including osteoporotic fractures reported post-marketing in patients taking Medroxyprogesterone acetate.
