1. What TOPAMAX is and what it is used for

TOPAMAX belongs to a group of medicines called "antiepileptic medicines". It is used:

  • alone, for the treatment of epileptic seizures in adults and children over 6 years of age
  • in combination with other medicines, for the treatment of epileptic seizures in adults and children from 2 years of age
  • to prevent migraine in adults

2. What you should know before taking TOPAMAX

Do not take Topamax

  • if you are allergic (hypersensitive) to topiramate or any of the excipients of this medicine (listed in section 6).
  • for migraine prevention if you are pregnant or if you are a woman of childbearing potential unless you are using an adequate method of contraception (see section “Pregnancy and breastfeeding” for more information). You should discuss with your doctor which type of contraception is best to use during treatment with Topamax.

If you are unsure whether any of the conditions listed above apply to you, speak with your doctor or pharmacist before taking Topamax.

Warnings and precautions

Talk to your doctor or pharmacist before taking Topamax if:

  • you have kidney problems, particularly kidney stones, or if you are undergoing renal dialysis
  • you have a history of blood or body fluid disorders (metabolic acidosis)
  • you have liver problems
  • you have eye problems, particularly glaucoma
  • you have growth problems
  • your diet is high in fat (ketogenic diet)
  • you are taking Topamax to treat epilepsy and you are pregnant or are a woman of childbearing potential (for further information, see section “Pregnancy and breastfeeding”).

If you are unsure whether any of the conditions listed above apply to you, speak with your doctor or pharmacist before starting treatment with Topamax.

It is important that you do not stop taking this medicine without first consulting your doctor.

You should also speak with your doctor before taking any other medicine containing topiramate prescribed as an alternative to Topamax.

Weight loss may occur while taking Topamax; therefore, your weight should be monitored regularly during treatment. If you lose too much weight, or if a child taking the medicine does not gain sufficient weight, consult your doctor.

A small number of patients treated with antiepileptic medicines such as Topamax have experienced suicidal thoughts or self-harming thoughts. If you experience any such thoughts at any time, contact your doctor immediately.

Topamax may cause serious skin reactions. Inform your doctor immediately if you develop a rash and/or blisters (also see section 4 "Possible side effects").

Topamax may, in rare cases, cause elevated levels of ammonia in the blood (seen in blood tests), which may lead to changes in brain function, especially if you are taking a medicine called valproic acid or sodium valproate. Since this may be a serious condition, inform your doctor immediately if you experience any of the following symptoms (also see section 4 “Possible side effects”):

  • difficulty thinking, remembering information, or solving problems
  • reduced alertness or awareness
  • feeling very drowsy and lacking energy

At higher doses of Topamax, the risk of developing these symptoms may increase.

Other medicines and Topamax

Inform your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines. Topamax may interact with other medicines. Sometimes, the dose of either Topamax or your other medicines may need to be adjusted.

In particular, inform your doctor or pharmacist if you are taking:

  • other medicines that impair thinking, concentration, or muscle coordination (e.g., central nervous system depressants such as muscle relaxants and sedatives).
  • oral contraceptive pills. Topamax may reduce the effectiveness of oral contraceptives. Discuss with your doctor which type of contraception is best to use during treatment with Topamax.

Inform your doctor if you notice any changes in your menstrual bleeding while taking oral contraceptives and Topamax.

Keep a list of all the medicines you are taking. Show this list to your doctor or pharmacist before starting any new medicine.

Other medicines to discuss with your doctor or pharmacist include other antiepileptic medicines, risperidone, lithium, hydrochlorothiazide, metformin, pioglitazone, glibenclamide, amitriptyline, propranolol, diltiazem, venlafaxine, flunarizine, St John’s wort (Hypericum perforatum) (an herbal preparation used to treat depression), and warfarin (used to thin the blood).

If you are unsure whether any of the conditions listed above apply to you, speak with your doctor or pharmacist before using Topamax.

Topamax with food and drink

You may take Topamax during or between meals. Drink plenty of fluids throughout the day when taking Topamax to help prevent kidney stone formation. You should avoid drinking alcohol during treatment with Topamax.

Pregnancy and breastfeeding

Migraine prevention:

Topamax may harm the unborn baby. You must not use Topamax if you are pregnant. You must not use Topamax for migraine prevention if you are a woman of childbearing potential unless you are using an effective method of contraception. Ask your doctor about the best type of contraception and whether Topamax is suitable for you. A pregnancy test must be performed before starting treatment with Topamax.

Epilepsy treatment:

If you are a woman of childbearing potential, you should discuss with your doctor other possible treatments instead of Topamax. If you decide to use Topamax, you must use an effective method of contraception. Ask your doctor about the best type of contraception to use during treatment with Topamax. A pregnancy test must be performed before starting treatment with Topamax.

As with other antiepileptic medicines, there is a risk of harm to the unborn baby if Topamax is used during pregnancy. Make sure you fully understand the risks and benefits of using Topamax for epilepsy during pregnancy.

  • If you take Topamax during pregnancy, your baby has an increased risk of birth defects, particularly cleft lip (a split in the upper lip) and cleft palate (a split in the roof of the mouth). Male newborns may also have a malformation of the penis (hypospadias). These defects may occur early in pregnancy, even before you know you are pregnant.
  • If you take Topamax during pregnancy, your baby may be smaller than expected at birth. Speak with your doctor if you have questions about this risk.
  • There may be other medicines available to treat your condition that carry a lower risk of birth defects.
  • Inform your doctor immediately if you become pregnant while taking Topamax. You and your doctor will need to decide whether to continue taking Topamax during pregnancy.

Breastfeeding

The active substance in Topamax (topiramate) is excreted in human milk. Effects have been observed in infants breastfed by treated mothers, including diarrhoea, drowsiness, irritability, and poor weight gain. Therefore, your doctor will discuss with you whether to discontinue breastfeeding or discontinue treatment with Topamax, taking into account the importance of the treatment for the mother and the potential risk to the infant.

Breastfeeding mothers taking Topamax should inform their doctor as soon as possible if the baby shows any unusual symptoms.

Driving and using machines

Dizziness, fatigue, and vision problems may occur during treatment with Topamax. Do not drive or operate tools or machinery without first discussing this with your doctor.

Topamax contains sucrose

If your doctor has diagnosed you with a sugar intolerance, contact your doctor before taking this medicine.

Other ingredients

This medicine contains less than 1 mmol of sodium (23 mg) per capsule, i.e., essentially “sodium-free”.

3. How to take TOPAMAX

Always take this medicine exactly as instructed by your doctor. If you have any doubts, consult your doctor or pharmacist.

  • Your doctor will usually start you on a low dose of Topamax and then gradually increase it until the best dose for you is reached.
  • The hard capsules of Topamax may be swallowed whole or opened and their contents mixed with a spoonful of soft food of any kind, for example: applesauce, cream, ice cream, baby food, pudding, or yogurt. Immediately afterwards, drink fluids to make sure you have swallowed all of the mixture of food and medicine.
  • Hold the hard capsule upright so that you can read the word “TOP”.
  • Carefully unscrew the transparent portion of the capsule. This may be easier to do if you place the capsule on a small amount of food onto which you will then pour the granules.
  • Pour the entire contents of the capsule onto the spoonful of soft food, taking care that the full prescribed dose is poured onto the food.
  • Make sure you immediately swallow the entire mixture of granules and food from the spoon. Do not chew. Immediately drink fluids to ensure that the entire mixture has been swallowed.
  • Never store the mixture of medicine and food for later use.
  • Topamax may be taken before, during, or after a meal. Drink plenty of fluids throughout the day to help prevent kidney stones while taking Topamax.

If you take more Topamax than you should

  • Contact a doctor immediately. Take the medicine pack with you.
  • You may feel drowsy, tired, or less alert; lose coordination; have difficulty speaking or concentrating; experience double or blurred vision; feel dizzy due to low blood pressure; feel depressed or agitated; or have abdominal pain or seizures. If you are taking other medicines together with Topamax, overdose may occur.

If you forget to take Topamax

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

If you stop taking Topamax
Do not stop taking this medicine unless your doctor tells you to. Your symptoms may return. If your doctor decides to stop this medicine, your dose may be gradually reduced over several days.
If you have any questions about how to use this medicine, ask your doctor or pharmacist.

Weight loss may occur while using Topamax, therefore your weight should be monitored regularly during treatment. If you lose too much weight, or if a child taking this medicine does not gain sufficient weight, consult your doctor.

A small number of people treated with antiepileptic medicines such as Topamax have experienced suicidal thoughts or self-harming thoughts. If at any time you have such thoughts, contact your doctor immediately.

Topamax can cause serious skin reactions. Inform your doctor immediately if you develop a rash or blisters (see also section 4 “Possible side effects”).

  • feeling very drowsy and lacking energy

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