Hormone therapy showdown: can dydrogesterone tame teen irregular periods?

NCT ID NCT07703488

First seen Jul 14, 2026 · Last updated Jul 15, 2026 · Updated 1 time

Summary

This study looks at whether dydrogesterone, a hormone pill, works better than a common birth control pill (drospirenone and ethinylestradiol) for treating irregular, heavy, or prolonged periods in teenagers aged 10 to 19. The main goal is to see how many teens have normal cycles after six months of treatment. Researchers will also track side effects, bleeding patterns, and quality of life. The findings could help doctors choose the best hormone therapy for young people with ovulation-related bleeding problems.
