Crinone Progesterone vaginal gel 8% – patient leaflet, side effects, dosage

1. What Crinone is and what it is used for

The full name of your medicine is Crinone 8% w/w vaginal gel. In this leaflet the shorter name Crinone is used. Crinone contains a hormone called progesterone. When the gel is inserted into your vagina, the progesterone is slowly released into your bloodstream throughout the day.

Crinone is used to give you extra progesterone in the treatment of infertility due to incorrect levels of progesterone during the menstrual cycle or when you are having an assisted fertility procedure. This is to help you get pregnant. You may also be asked to continue using Crinone to support your new pregnancy.

3. How to use Crinone

Always use Crinone exactly as your doctor has told you. Check with your doctor or pharmacist if you are not sure.

Recommended dose

Insert the contents of one applicator of Crinone into your vagina each day, starting after your doctor tells you that you have ovulated, or on the 18^th-21^st day of your menstrual cycle. (The first day of your menstrual cycle is the day your period starts.)

When used during in-vitro fertilisation, from the day of the embryo transfer, insert the contents of one applicator of Crinone into your vagina each day, preferably in the morning. Once tests confirm that you are pregnant, you may be asked to keep using Crinone to support your new pregnancy – for a total of 30 days.

The applicator is designed in such a way that an exact amount of gel (1.125 g, containing 90 mg progesterone) is delivered. It is expected that a small amount of gel will be left in the applicator. This can be thrown away as you will have received all of the medicine that you need.
