Evidence-based recommendations for use of progesterone in threatened miscarriage.

Evidence-based recommendations
Testing of progesterone levels is not required [10,11] When a threatened miscarriage is confirmed, oral dydrogesterone is recommended at 40 mg, followed by 10 mg twice daily [31] The above regimen should continue for one to two weeks after the end of clinical symptoms of miscarriage [25]
