Topamax may cause severe skin reactions, contact your doctor immediately if you develop a skin rash and/or blisters (see also section 4 “Possible side effects”).

Topamax may cause high levels of ammonia in the blood (seen in blood tests) which may cause a change in brain function, especially if you are also taking a medicine called valproic acid or sodium valproate.

You may increase the risk of developing these symptoms at higher doses of Topamax.

Other medicines and Topamax

Especially, inform your doctor or pharmacist if you are taking:

• other medicines that impair or reduce your thoughts, concentration, or muscle coordination (e.g. central nervous system depressants such as muscle relaxants and sedatives).
• hormonal contraceptives. Topamax may make hormonal contraceptives less effective. You should use an additional barrier method such as a condom or diaphragm. You should consult your doctor about the best contraceptive method to use while taking Topamax.

Tell your doctor if you change your menstrual bleeding while taking hormonal contraceptives and Topamax. You may experience irregular menstrual bleeding. In this case, continue taking the hormonal contraceptives and inform your doctor.

Pregnancy and breastfeeding

Important advice for fertile women:

Topamax may cause harm to a baby during pregnancy. If you are a fertile woman, consult your doctor about other possible treatments. Visit your doctor to review your treatment and discuss the risks at least once a year.

Prevention of migraines

• Do not take Topamax if you are pregnant.
• Do not use Topamax if you are a fertile woman, unless you are using a highly effective contraceptive method.
• A pregnancy test should be performed before starting treatment with Topamax in a fertile woman.

Treatment of epilepsy

• Do not take Topamax if you are pregnant, unless no other treatment offers sufficient control of seizures.
• Do not use Topamax if you are a fertile woman, unless you are using a highly effective contraceptive method. The only exception is if Topamax is the only treatment that offers sufficient control of seizures and if you plan to become pregnant. You must consult your doctor to ensure that you have received information about the risks of taking Topamax during pregnancy and about the risks of seizures during pregnancy. See below under “Pregnancy, breastfeeding and fertility – Important advice for women”.
• A pregnancy test should be performed before starting treatment with Topamax in a fertile woman.

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 baby during pregnancy if Topamax is used during pregnancy.

• If you take Topamax during pregnancy, your child will have a higher chance of having birth defects. Approximately 4 to 9out of 100 children of women taking topiramate will have birth defects. This compares with 1‑3out of 100 children born to women with epilepsy who are not taking an antiepileptic drug. In particular, there have been reports of cleft lip (a split in the upper lip) and cleft palate (a split in the palate). Newborn boys may also have a genital malformation (hypospadias). These defects can develop in the early stages of pregnancy, even before you know you are pregnant.
• If you take Topamax during pregnancy, your child may be at a 2 to 3times 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 an antiepileptic drug.
• If you take Topamax during pregnancy, your child may be smaller and weigh less than expected at birth. In one study, 18% of children of mothers taking topiramate during pregnancy were smaller and weighed less than expected at birth, while 5% of children born to mothers without epilepsy who were not taking an antiepileptic drug 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.

Necessity of contraceptive methods for fertile women:

• If you are a fertile woman, consult your doctor about other possible treatments instead of taking Topamax. If the decision is made to use Topamax,highly effective contraceptive methods should be used during your treatment and for at least 4weeks after the last dose of Topamax.
• Highly effective contraceptive methods (such as an intrauterine device) or two complementary contraceptive methods (such as a contraceptive pill together with a barrier 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, an additional barrier method (such as a condom or diaphragm) should be used.
• Inform your doctor if you experience irregular menstrual bleeding.

Use of Topamax in girls:

If you are the parent/caregiver of a girl treated with Topamax,you should consult your doctor immediately once your daughter experiences her first menstrual period (menarche). The doctor will inform you about the risks to a baby during pregnancy due to exposure to topiramate during pregnancy, and about the need to use highly effective contraceptive methods.

If you want to become pregnant while taking Topamax:

• Book an appointment with your doctor.
• Do not stop using your contraceptive method until you have discussed this with your doctor.

• If you are taking Topamax for epilepsy, do not stop taking this medicine until you have consulted with your doctor, as your condition may worsen. A worsening of your epilepsy may put you or your baby during pregnancy at risk.
• Your doctor will re-evaluate your treatment and evaluate alternative treatment options. The doctor will advise you about the risks of Topamax during pregnancy. The doctor may also refer you to another specialist.
