What GyMiso® is used for

GyMiso® contains misoprostol. It belongs to a group of medicines called prostaglandins. It acts like prostaglandin E1. GyMiso® induces contractions of the smooth muscle and relaxation of the cervix. These properties help open the cervix and push out the contents of the uterus.

GyMiso® can therefore be used to terminate a pregnancy.

GyMiso® is recommended for the medical termination of pregnancy. It is recommended for use up to 49 days after your last menstrual period. It is given in combination with another medicine called mifepristone, which blocks progesterone, a hormone that is needed for pregnancy to continue.

Ask your doctor if you have any questions about why GyMiso® has been prescribed for you. Your doctor may have prescribed it for another reason.

This medicine is available only with a doctor’s prescription.

How GyMiso® is given

How much to take

Your doctor will tell you how many tablets you need to take and when to take them.

GyMiso® is usually taken 36 to 48 hours after you have taken mifepristone.. You will need to take four GyMiso® tablets (misoprostol 800 micrograms). These are taken either as four tablets in one dose, or as two tablets followed two hours later by another two tablets.

How to take GyMiso®

GyMiso® should be swallowed with water.

GyMiso® can also be taken by holding the tablet in your mouth, between the cheek and gum, for 30 minutes before swallowing any fragments with water.

It is recommended that GyMiso® should be taken on an empty stomach - 2 hours before or after a meal.

After you take GyMiso® tablets, you should stay at home and rest for 3 hours. Vaginal bleeding will occur and the pregnancy may be expelled within a few hours of taking GyMiso® or during the next few days. The bleeding lasts on average for 10 to 16 days and may be heavy.

It is very important that you have follow up with your doctor 14 to 21 days after you take mifepristone and GyMiso®, to ensure that the termination was complete, because incomplete termination will increase the risk of serious infection or bleeding.

It is recommended that you do not travel away from home during the time that you are bleeding so that you can visit your doctor or clinic if necessary.

In case of heavy and prolonged bleeding, you should contact your doctor immediately in order to schedule an appointment.

In rare cases, a termination can occur after you take mifepristone but before you take GyMiso®. It is essential that you are checked to confirm that a complete termination has occurred. If this occurs, you should contact your doctor immediately in order to schedule an appointment.

If you forget to take your dose of GyMiso®

Contact your doctor immediately if you forget to take GyMiso® tablets and it is greater than 48 hours after you have taken a mifepristone 200 mg tablet.

If you are given too much (overdose)

GyMiso® is given to you by your doctor. An overdose is not likely to occur. Ask your doctor if you have any concerns.

While you are being given GyMiso®

Things you must do

If you are pregnant

In some cases treatment with mifepristone and GyMiso® may not result in a termination of pregnancy.

You must keep all of your doctor’s appointments so that your progress can be checked. This is very important.

If treatment with mifepristone and GyMiso® does not work, a termination can be arranged using another method.

If treatment with mifepristone and GyMiso® does not work and you wish to keep your pregnancy, it is not known if mifepristone can cause harm to your baby. It is believed, though, that GyMiso® can cause harm to your baby. You need to tell your doctor or nurse about mifepristone and GyMiso® so that they can carefully monitor your pregnancy.

If you are Rhesus negative, the use of mifepristone and GyMiso® requires that your doctor will take measures to prevent Rhesus factor sensitization, along with the general measures taken during any pregnancy termination.

If you are breastfeeding

GyMiso® should not be taken if you are breastfeeding.

If you are taking other medicines

If you are about to be started on any new medicines, remind your doctor or pharmacist that you have recently been given mifepristone and GyMiso®. Ask your doctor or pharmacist for advice before taking any medicine.

Tell any other doctors, dentists, and pharmacists who treat you that you have recently been given these medicines.

If you plan to become pregnant, tell your doctor that you have been given this medicine. Your doctor can discuss with you the risks and benefits involved.

Side effects

Tell your doctor or nurse as soon as possible if you do not feel well while you are being given mifepristone and GyMiso®.

Do not be alarmed by the following list of side effects, you may not experience any of them.

Tell your doctor if you notice any of the following and they worry you:

  • headache
  • vaginal bleeding which may be heavy or prolonged
  • spotting
  • cramps
  • breast tenderness
  • fainting
  • hot flushes, skin rashes or itching
  • side effects related to GyMiso® such as nausea, vomiting, diarrhoea, dizziness, abdominal discomfort, abdominal pain, cramps, fatigue and chills and/or fever.

Tell your doctor if you notice anything that is making you feel unwell.

Serious infections are very rare in a medical termination of pregnancy and can be potentially life threatening. If you have symptoms occurring more than 24 hours after taking misoprostol of ongoing abdominal pain, or feeling unwell, or feeling weak, with or without a fever you should contact your doctor without delay.

Vaginal bleeding usually starts a few hours after taking misoprostol tablets. Bleeding can occur for 10 to 16 days and it is usual for bleeding to be heavier than a normal period for 2 to 3 days. Contact your doctor immediately if you find you have very heavy bleeding and have soaked more than 2 pads per hour over 2 hours.

Other side effects not listed above may also occur in some people.
