Warnings and precautions

Zonisamida belongs to a group of medications (sulfonamides) that may cause severe allergic reactions, severe rashes, and blood disorders, which very rarely may causedeath(see section 4. Possible side effects).

The use of zonisamida may cause high levels of ammonia in the blood, which could change brain function, especially if you are also taking other medications that may increase ammonia levels (e.g., valproate), if you have a genetic disorder that causes excessive ammonia production in the body (urea cycle disorder), or if you have liver disorders. Inform your doctor immediately if you feel drowsy or confused in an unusual way.

Consult your doctor or pharmacist before starting to take Zonisamida Teva if you:

• areunder 12 years old, as you may be at higher risk of developingdecreased sweating, heatstroke, pneumonia, and liver problems.Zonisamida is not recommended forchildren under 6 years old.
• areelderly, as you may need to adjust the zonisamida dose, and you may be at higher risk of developing an allergic reaction, severe rash, swelling of legs and feet, and itching when taking zonisamida (see section 4. Possible side effects).
• haveliver problems, as you may need to adjust the zonisamida dose.
• have eye problems such as glaucoma
• havekidney problems, as you may need to adjust the zonisamida dose.
• have previously hadkidney stones, as you may be at higher risk of developing more kidney stones.Reduce the risk of kidney stones by drinking enough water.
• live in a place or are going on vacation to a place where it is hot. Zonisamida may cause you to sweat less, which can lead to a higher body temperature.Reduce the risk of overheating by drinking enough water and staying cool.

• are pregnant or may be pregnant (see section “pregnancy, breastfeeding, and fertility” for more information)

If any of these statements apply to you, inform your doctor before taking Zonisamida Teva.

Children and adolescents

Consult your doctor about the following risks:

• Weight:You should monitor your child's weight monthly and see your doctor as soon as possible if they are not gaining enough weight.Zonisamida is not recommended for children who are underweight or have a poor appetite, and should be used with caution in children with a weight under 20 kg.
• Increased blood acidity and kidney stones: reduce these risks by ensuring your child drinks enough water and does not take any medication that may cause kidney stones (see Use of Zonisamida Teva with other medications). Your doctor will monitor your child's blood bicarbonate levels and kidneys (see also section 4).

Do not administer this medication to childrenunder 6 years oldas it is not known if the potential benefits outweigh the risks in this age group.

Use of Zonisamida Teva with other medications

Inform your doctor or pharmacist if you are using, have used recently, or may need to use any other medication.

• Zonisamida should be used with caution in adults if taken with medications that may cause kidney stones, such astopiramateoracetazolamide. In children, this combination is not recommended.
• Zonisamida may increase the levels of medications such asdigoxinandquinidinein the blood, and therefore may need to be reduced.
• Other medications such asphenytoin, carbamazepine, phenobarbitalandrifampicinmay decrease the levels of zonisamida in the blood, which may require an adjustment of the Zonisamida Teva dose.

Taking Zonisamida Teva with food and drinks

Zonisamida Teva can be taken with or without food.

Pregnancy, breastfeeding, and fertility

Women of childbearing age should use effective contraceptive measures during zonisamida treatment and for one month after stopping zonisamida.

If you intend to become pregnant, talk to your doctor before stopping contraceptives and before becoming pregnant about the possibility of switching to other suitable treatments. If you are or think you may be pregnant, inform your doctor or pharmacist immediately. Do not stop treatment without consulting your doctor.

You should only take zonisamida during pregnancy if your doctor advises it. Research has shown a higher risk of birth defects in children of women taking antiepileptic medications. The risk of birth defects or neurological developmental disorders (brain development problems) for your child after taking zonisamida during pregnancy is unknown. A study showed that children whose mothers took zonisamida during pregnancy were smaller than expected for their age at birth, compared to children whose mothers were treated with lamotrigine monotherapy. Make sure you are informed in detail about the risks and benefits of using zonisamida for epilepsy during pregnancy.

Do not breastfeed while taking zonisamida or for one month after stopping zonisamida.

There are no clinical data on the effects of zonisamida on human fertility. Animal studies have shown changes in fertility parameters.
