Dimetriose (Gestrinone) is made by Hoechst for the treatment of endometriosis.
What is Dimetriose?
Dimetriose is a synthetic (artificial) hormone and is an antiprogestin (it acts against the hormone progestin that is naturally present in women).
How Dimetriose works
Dimetriose is thought to work in two ways. It acts on the pituitary gland (gland situated at the base of the brain) by suppressing the production by the pituitary of Follicle Stimulating Hormone (FSH) and Leutinising Hormone (LH). These two hormones stimulate the ovaries to ovulate each month. If ovulation stops, the growth of endometriosis deposits should also stop. Dimetriose also works directly on the deposits of endometriosis suppressing their growth. Periods usually stop during treatment, but some spotting of blood may occur.
Administration and dosage of Dimetriose
Dimetriose comes in capsule form in the strength of 2.5mgs and one capsule is taken twice a week.
Dimetriose should be started on the first day of the monthly cycle to avoid exposing a pregnancy to the side effects of Dimetriose.
The second dose is taken three days later. Thereafter, Dimetriose should be taken at the same time on the same two days of the week for the duration of the treatment.
Dimetriose is normally taken for a course of six months.
What happens if a dose of Dimetriose is missed?
If one dose is missed, a capsule should be taken as soon as possible and the normal cycle resumed.
If two or more doses are missed, treatment should be stopped and re-started on the first day of the next period. A negative pregnancy test should be achieved before restarting the treatment.
Dimetriose is not suitable for the treatment of children or the elderly.
