• In the case of epilepsy, do not take Topiramate Normon if you are a woman of childbearing potential unless you are using a highly effective contraceptive method. The only exception is if Topiramate Normon is the only treatment that provides adequate control of your seizures and if you plan to become pregnant.

The risks of topiramate when taken during pregnancy (regardless of the condition for which topiramate is used) are as follows:

There is a risk of harm to the unborn baby during pregnancy if Topiramate Normon is used during pregnancy.

• If you take Topiramate Normon during pregnancy, your child will have a higher chance of having birth defects. In women taking topiramate, around 4 to 9 children out of 100 will have birth defects. This compares to 1-3 children out of 100 born to women who do not have epilepsy and are not taking antiepileptic treatment. In particular, cleft lip (a split in the upper lip) and cleft palate (a split in the roof of the mouth) have been seen. Boys born may also have a malformation of the penis (hypospadias). These defects can develop in the early stages of pregnancy, even before you know you are pregnant.
• If you take Topiramate Normon during pregnancy, your child may have a 2 to 3 times higher risk of developing autism spectrum disorders, intellectual disabilities or attention deficit hyperactivity disorder (ADHD) compared to children born to women with epilepsy who are not taking antiepileptic medication.
• If you take Topiramate Normon during pregnancy, your child may be smaller and weigh less than expected at birth. In one study, 18% of children born to mothers taking topiramate during pregnancy were smaller and weighed less than expected at birth, while 5% of children born to mothers without epilepsy and not taking antiepileptic medication were smaller and weighed less than expected at birth.
• Consult your doctor if you have questions about this risk during pregnancy.
• There may be other medicines to treat your condition with a lower risk of birth defects.

Need for contraceptive methods for women of childbearing potential:

• If you are a woman of childbearing potential, consult your doctor about other possible treatments instead of taking Topiramate Normon. If the decision is made to use Topiramate Normon, highly effective contraceptive methods should be used during treatment and for at least 4 weeks after the last dose of Topiramate Normon.
• A highly effective contraceptive method (such as an intrauterine device) or two complementary contraceptive methods such as a contraceptive pill together with a barrier contraceptive method (such as a condom or diaphragm) should be used. Consult your doctor about the most suitable contraceptive methods for you.
• If you are taking hormonal contraceptives, there is a possibility of reduced effectiveness of the hormonal contraceptive due to topiramate. Therefore, a barrier contraceptive method (such as a condom or diaphragm) should be used.
• Tell your doctor if you experience irregular menstrual bleeding.

Use of Topiramate Normon in girls:

If you are the parent or caregiver of a girl treated with Topiramate Normon, you should consult your doctor immediately once your daughter experiences her first menstrual period (menarche).
