thank you for your query.
Etosys is not the treatment for irregular period, but it is given for heavy and prolonged bleeding.
if that was the case, then yes, it is the correct medication.
Sometimes, a heavy period might be due to anxiety, stress , travelling or due to simple harmless variations in the normal menstrual cycle.
other causes of prolonged periods
are endometrial polyps, cervical polyps, endometriosis, endometrial hyperplasia
, hormonal medications, thyroid disorder
, polycystic ovaries
These can only be evaluated when you visit a gynecologist and have a complete examination and necessary blood tests and pelvic ultrasound.
