Crinone® contains a hormone called progesterone. When the gel is inserted into your vagina, the progesterone is slowly released into your body throughout the day.
Crinone® is used to give you extra progesterone when you are having an assisted fertility procedure, to help you get pregnant. You may also be asked to continue using Crinone® to support your pregnancy.
Do not stop using your medication without checking with your healthcare professional.
How to use Crinone®
| Step 1: Getting your applicator ready Remove the applicator from the packaging. Grip the applicator by the thick end between your thumb and index finger. Face the thin end of the applicator down to the ground and shake the applicator down to move all the gel inside to the thin end. The applicator contains a plastic ball to help the gel to move down to the tip of the applicator. The ball also helps to control the release of the gel. The applicator is designed so that the ball cannot exit it. | |
| Step 2: Opening your applicator Grip the applicator by the flat part of the thick end. Twist off and remove the cap from the opposite thin end. To stop the gel from flowing out before use, do not press the air tank at the thick end at this stage. | |
| Step 3: Inserting your applicator Lean back or lie down with your knees bent and spread apart. Carefully insert the applicator well into your vagina, until your hand touches your body. Press the air tank at the thick end of the applicator firmly to deliver the gel from the applicator into your vagina. | |
| Step 4: After using your applicator Throw away the applicator, including the small amount of gel that is left inside. Use each applicator only once. You do not have to stay lying down once you have applied the gel. This is because activities like walking may help to spread the gel onto the walls of the vagina. |
The applicator is designed in such a way that an exact amount of gel 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.
If you forget to use a dose, use it as soon as you remember if it is not close to the next dose. If you missed a dose, contact your nurse or doctor immediately for advice. Do not use two doses together to make up for the missed dose.
