What Endometrin is used for
Endometrin is provided as a pessary (or vaginal tablet) that contains the natural female hormone, progesterone.
Endometrin is for women who need extra progesterone while undergoing treatment in an Assisted Reproductive Technology (ART) programme (e.g. IVF).
Progesterone acts on the lining of the uterus (womb) and it helps you to become and to stay pregnant when you are treated for infertility.
Your doctor may have prescribed Endometrin for another purpose. Ask your doctor if you have any questions why this medicine has been prescribed for you.
Endometrin is available only with a doctor's prescription.
This medicine is not addictive.

How to use Endometrin
How much to use
Your doctor or pharmacist will tell you how many tablets you need to use each day. The usual dosage is one 100 mg tablet placed directly into the vagina three times daily starting on the day of egg retrieval.
Follow all directions given to you by your doctor carefully. They may differ from the information contained in this leaflet.
Endometrin tablets are intended to be placed directly into the vagina. An applicator is provided in the pack to help administer the tablets.
Follow the directions on how to administer the tablet below:
- wash your hands thoroughly with soap and water
- unwrap the applicator and remove one vaginal tablet from the blister
- put one tablet in the space provided at the end of the applicator. The tablet should fit securely and not fall out
- the applicator with the tablet may be inserted into the vagina while you are standing, sitting, or when lying on your back with your knees bent. Gently insert the thin end of the applicator well into the vagina
- push the plunger to release the tablet
- remove the applicator and rinse it thoroughly in warm running water, wipe dry with a soft tissue and keep the applicator for subsequent use.
The directions on how to administer the tablet are also provided with each pack of Endometrin.
If you do not understand the instructions, ask your doctor or pharmacist for help.
How long to use it
The use of Endometrin may be continued for up to 10 weeks if pregnancy is confirmed (12 week of gestation).
If you forget to use it
If it is almost time for your next dose, skip the dose you missed and use your next dose when you are meant to, as usual.
Otherwise, use it as soon as you remember, and then go back to using your medicine as you would normally.
Do not use a double dose to make up for the dose that you missed.
If you are not sure what to do, talk to your doctor or pharmacist. If you have trouble remembering to use your medicine, ask your pharmacist for some hints.
If you use too much (overdose):
Immediately telephone your doctor or Poisons Information Centre (telephone 13 11 26), or go to accident and emergency at your nearest hospital, if you think that you or anyone else may have used too much Endometrin. Do this even if there are no signs of discomfort or poisoning.
