1. What Topamax is and what it is used for

Topamax belongs to a group of medicines called antiepileptic drugs. It is used:

  • as monotherapy in the treatment of epileptic seizures in adults and children above 6 years of age,
  • in combination with other medicines for the treatment of epileptic seizures in adults and children aged 2 years and older,
  • for the prevention of migraine headaches in adults.

2. Important information before using Topamax

When not to use Topamax

  • if the patient is allergic to topiramate or any of the other ingredients of this medicine (listed in section 6).

Prevention of migraine

  • Topamax must not be used during pregnancy.
  • If the patient is a woman of childbearing age, Topamax must not be used without the use of a highly effective method of contraception during treatment. See below under "Pregnancy and breastfeeding – important advice for women".

Treatment of epilepsy

  • Topamax must not be used if the patient is pregnant, unless no other treatment provides adequate seizure control.
  • If the patient is a woman of childbearing age, Topamax must not be used without the use of a highly effective method of contraception during treatment. The only exception is when Topamax is the only medicine providing adequate seizure control and the patient is planning a pregnancy. Talk to the doctor to ensure that the patient has received information about the risks of using Topamax during pregnancy and the risk of seizures occurring during pregnancy. See below under "Pregnancy and breastfeeding – important advice for women".

Please read the Patient Guide provided by your doctor or
scan the QR code (see section 6 "Contents of the pack and other information").
A patient card is included in the Topamax packaging, reminding of the risks associated
with pregnancy.
If the patient is unsure whether any of the symptoms described above apply, they should
consult a doctor or pharmacist before using Topamax.
Warnings and precautions
Before starting Topamax, discuss with the doctor if any of the following apply:

  • kidney problems, especially kidney stones or dialysis,
  • abnormalities in blood and body fluids (metabolic acidosis),
  • liver disorders,
  • vision problems, especially glaucoma,
  • growth disorders,
  • if the patient is on a high-fat diet (ketogenic diet),
  • if the patient is a woman of childbearing age. Topamax taken during pregnancy may harm the unborn child. During treatment and for at least 4 weeks after taking the last dose of Topamax, a highly effective method of contraception must be used. Further information is provided in the section "Pregnancy and breastfeeding",
  • if the patient is pregnant. Topamax taken during pregnancy may harm the unborn child. If in doubt whether any of the above warnings apply, consult a doctor before using Topamax.

If the patient has epilepsy, it is important not to stop taking the medicine without consulting
the doctor.
The patient should consult their doctor before taking any medicine containing topiramate prescribed
as a substitute for Topamax.
While taking Topamax, the patient may lose weight; therefore, body weight should be monitored
regularly during treatment. If the patient loses too much weight or if a child taking this medicine does not gain sufficient weight, consult the doctor.
In a small number of people taking antiepileptic medicines such as Topamax, thoughts of harming themselves or of suicide have occurred.
If such thoughts occur, contact the doctor immediately.
Topamax may cause severe skin reactions; if a rash and/or blisters on the skin occur, inform the doctor immediately (see also section 4. "Possible side effects").
Topamax may rarely cause increased blood ammonia levels (detected in blood tests), which may lead to changes in brain function, especially if the patient is also taking a medicine containing valproic acid or sodium valproate. Since this may be an acute condition, inform the doctor immediately if any of the following adverse effects occur (see also section 4. "Possible side effects"):

  • difficulty thinking, remembering or solving problems,
  • reduced alertness or awareness,
  • feeling very sleepy with lack of energy.

The risk of these symptoms may increase when high doses of Topamax are used.
Topamax and other medicines
Tell the doctor or pharmacist about all medicines currently or recently taken, as well as any medicines the patient plans to take. Topamax may interact with other medicines. Therefore, sometimes the dose of other medicines taken by the patient may need to be adjusted, or the dose of Topamax may need to be changed accordingly.
In particular, inform the doctor or pharmacist if the patient is taking:

  • other medicines that have harmful effects or reduce thinking, concentration, or muscle coordination (e.g., central nervous system depressants such as muscle relaxants and sedatives),
  • hormonal contraceptives. Topamax may reduce the effectiveness of hormonal contraceptives. An additional barrier method of contraception, such as a condom or diaphragm/cervical cap, should be used. Discuss with the doctor the best method of contraception to use during treatment with Topamax.

Tell the doctor if menstrual bleeding changes while using hormonal contraceptives and Topamax. Irregular bleeding may occur.
In such a case, continue using hormonal contraceptives and inform the doctor.
Keep a list of all medicines being taken. Show this list to the doctor and pharmacist when starting a new therapy.
The use of other medicines such as antiepileptic drugs, digoxin, risperidone, lithium, hydrochlorothiazide, metformin, pioglitazone, glibenclamide, amitriptyline, haloperidol, propranolol, diltiazem, venlafaxine, flunarizine, St John's wort (Hypericum perforatum) (used to treat depression), warfarin (an anticoagulant), should be discussed with the doctor or pharmacist.
If the patient is unsure whether the above information applies, consult a doctor or pharmacist before using Topamax.
Topamax with food, drink and alcohol
Topamax may be taken with or without food. Drink plenty of fluids during the day to
help prevent kidney stones while taking Topamax. Avoid drinking alcohol while taking
Topamax.
Pregnancy and breastfeeding
Important advice for women of childbearing potential
Topamax may harm the unborn child. Women of childbearing age should
discuss other possible treatment options with their doctor. Visit the doctor at least once a year to
review treatment and discuss risks.
Prevention of migraine

  • For migraine, Topamax must not be used during pregnancy.
  • For migraine, Topamax must not be used if the patient is of childbearing age unless she uses a highly effective method of contraception.
  • Before starting Topamax in a woman of childbearing age, a pregnancy test must be performed.

Treatment of epilepsy

  • For epilepsy, Topamax must not be used if the patient is pregnant, unless no other treatment provides adequate seizure control.
  • For epilepsy, Topamax must not be used if the patient is of childbearing age unless she uses a highly effective method of contraception. The only exception is when Topamax is the only medicine providing adequate seizure control and the patient is planning a pregnancy. Talk to the doctor to ensure that the patient has received information about the risks of using Topamax during pregnancy and the risk of seizures occurring during pregnancy, which may endanger the patient or the unborn child.
  • Before starting Topamax in a woman of childbearing age, a pregnancy test must be performed.

Risk of using topiramate during pregnancy (regardless of the condition for which topiramate is used):
There is a risk of harmful effects on the unborn child if Topamax is used
during pregnancy.

  • Using Topamax during pregnancy increases the risk of congenital malformations in the child. In women taking topiramate, congenital malformations occur in approximately 4 to 9 out of 100 children. For comparison, this rate is 1 to 3 out of 100 children born to women who do not have epilepsy and do not take antiepileptic medicines. In particular, cleft lip (cleft upper lip) and cleft palate (cleft palate) have been observed. In male newborns, a developmental abnormality of the penis (hypospadias) may also occur. These malformations may develop early in pregnancy, even before the patient knows she is pregnant.
  • When Topamax is used during pregnancy, the risk of autism spectrum disorders, intellectual disability, or attention deficit hyperactivity disorder (ADHD) in the child may be 2 to 3 times higher than in children born to women with epilepsy who do not take antiepileptic medicines.
  • When Topamax is used during pregnancy, the child may be smaller and have lower than expected birth weight. In one study, 18% of children born to mothers taking topiramate during pregnancy were smaller and weighed less than expected, compared to 5% of newborns of women without epilepsy who did not take antiepileptic medicines.
  • If in doubt, ask the doctor about the risks during pregnancy.
  • Other medicines used to treat this condition may be available that carry a lower risk of congenital malformations.

Necessity of using contraception in women of childbearing age:

  • Women of childbearing age should discuss with their doctor the possibility of using alternative treatments instead of Topamax. If the decision is made to start treatment with Topamax, a highly effective method of contraception must be used during treatment and for at least 4 weeks after taking the last dose of Topamax.
  • Use one highly effective contraceptive method (such as an intrauterine device) or two complementary methods of contraception, such as a contraceptive pill combined with a mechanical method (such as a condom or diaphragm/cervical cap). Talk to the doctor to determine which method of contraception is most suitable for the patient.
  • If the patient uses hormonal contraceptives, topiramate may reduce their effectiveness. Therefore, an additional barrier method of contraception (such as a condom or diaphragm/cervical cap) should be used.
  • If irregular menstrual bleeding occurs, inform the doctor.

Use of Topamax in girls:
Parents or guardians of a girl being treated with Topamax must contact the doctor immediately
when the girl has her first menstrual period. The doctor will inform them about the risk to
the unborn child from exposure to topiramate during pregnancy and the need to use a highly effective method of contraception.
If the patient wishes to become pregnant while taking Topamax:

  • Make an appointment with the doctor.
  • Do not stop using contraception until this issue has been discussed with the doctor.
  • If the patient is taking Topamax for epilepsy, do not stop taking it without consulting the doctor, as the condition may worsen.
  • The doctor will reassess the treatment and alternative treatment options. The doctor will inform the patient about the risks of using Topamax during pregnancy. The doctor may also refer the patient to another specialist.

If the patient becomes pregnant or suspects she may be pregnant while taking Topamax:

  • Make an urgent appointment with the doctor.
  • If taking Topamax for migraine prevention, stop taking the medicine immediately and contact the doctor, who will assess whether alternative treatment is needed.
  • If the patient is taking Topamax for epilepsy, do not stop taking it without consulting the doctor, as this may worsen the condition. Worsening of epilepsy may endanger the patient or the unborn child.
  • The doctor will reassess the treatment and alternative treatment options. The doctor will inform the patient about the risks of using Topamax during pregnancy. The doctor may also refer the patient to another specialist.
  • If Topamax is used during pregnancy, the patient will remain under close monitoring to assess the development of the unborn child.

Please read the Patient Guide provided by your doctor. The
Patient Guide can also be obtained by scanning the QR code; see section 6. "Contents of the pack
and other information". A patient card is included in the Topamax packaging, reminding
of the risks associated with using topiramate during pregnancy.
Breastfeeding
The active substance of Topamax (topiramate) passes into human milk. Adverse effects such as diarrhoea, drowsiness, irritability and poor weight gain have been observed in infants breastfed by mothers taking this medicine. Therefore, the doctor will discuss with the patient whether to stop breastfeeding or to stop using Topamax. The doctor will consider the importance of the medicine for the mother and the risk to the child.
Mothers taking Topamax while breastfeeding must inform the doctor immediately if they notice any change in their child's behaviour.
Driving and operating machinery
Dizziness, tiredness and vision disturbances may occur while taking Topamax.
Do not drive, operate any machinery or use tools before consulting a doctor.
Topamax contains sucrose
The hard capsules contain sucrose. If the patient has been informed by a doctor that they have an intolerance to certain sugars, they should consult the doctor before using this medicine.

3. How to take Topamax

This medicine should always be taken exactly as prescribed by your doctor. If in doubt, consult your doctor or pharmacist.

  • Your doctor will usually start treatment with a low dose of Topamax and gradually increase it until the optimal dose for the individual patient is established.
  • Topamax hard capsules may be swallowed whole. Alternatively, the capsule may be carefully opened and the entire contents sprinkled onto a small amount of soft food (on a teaspoon), such as applesauce, sweet custard, ice cream, porridge, pudding, or yoghurt. After each dose, drink some fluid to ensure that all the medicine and food have been swallowed.
  • Hold the hard capsule vertically to read the word “TOP” clearly.
  • Then unscrew the empty part of the capsule. Mixing the medicine with a small amount of soft food may be a better way to administer the medicine.
  • Sprinkle the capsule contents onto a teaspoonful of soft food, making sure that the entire dose is used.
  • Be sure to swallow the entire contents of the spoon containing the medicine/food mixture. Avoid chewing. Immediately after taking the medicine, drink a glass of fluid to ensure that all the medicine and food have been swallowed.
  • Never store the mixture of medicine and food for later use.
  • Topamax may be taken before, during, or after a meal. While taking Topamax, drink plenty of fluids to help prevent kidney stone formation.

Girls and women of childbearing age:
Treatment with Topamax should be initiated and supervised by a doctor experienced in the treatment of epilepsy or migraine. A medical check-up should be carried out at least once a year to monitor treatment.

Taking more Topamax than prescribed

  • Contact your doctor immediately. Take the medicine pack with you.
  • The patient may experience the following symptoms: drowsiness, feeling of fatigue or reduced alertness, lack of coordination, speech or concentration disturbances, double or blurred vision, dizziness due to low blood pressure, feelings of depression or agitation, abdominal pain, or seizures.

Overdose may also occur when Topamax is taken together with other medicines.

If you forget to take Topamax

  • If you miss a dose, take it as soon as possible. However, if it is almost time for the next dose, skip the missed dose and continue with your regular dosing schedule.
  • Do not take a double dose (two doses at the same time) to make up for a forgotten dose.
  • If you miss two or more doses, contact your doctor.

Stopping Topamax Do not stop taking this medicine unless your doctor tells you to. The symptoms of your underlying condition may return after stopping treatment. If your doctor decides to discontinue treatment, the dose of Topamax may be gradually reduced over a period of several days.
