1. What is Vigzip and what is it used for

Vigzip contains the active substance vigabatrin.

This medicine is used to help control various forms of epilepsy.

It is used in combination with your current medication to treat "hard-to-control" epilepsy. Initially, it will be prescribed by a specialist. Your response to treatment will be monitored.

It is also used to control infant spasms (West syndrome).

2. What you need to know before taking Vigzip

Do not take Vigzip

If you are allergic to vigabatrin or any of the other ingredients of this medicine (listed in section 6).

Warnings and precautions

Talk to your doctor before starting Vigzip if:

• you are breast-feeding
• you are pregnant or planning to become pregnant
• you have had depression or any other psychiatric disorder in the past
• you have had kidney problems
• you have had vision problems.

Loss of vision (loss of vision from the edges of your field of vision) may occur during treatment with vigabatrin. You should discuss this possibility with your doctor before starting treatment with this medicine. This loss of vision can be severe, leading to tunnel vision or loss of vision, and irreversible, so it must be detected early. It cannot be ruled out that this loss of vision may worsen after treatment is stopped. It is essential that you inform your doctor promptly if you notice any change in your vision. Your doctor will perform a visual field and visual acuity test before you start taking Vigzip and at regular intervals during treatment. Vigabatrin may cause decreased vision due to eye problems such as retinal disorders, blurred vision, optic atrophy, or optic neuritis (see section 4). If your vision changes, consult an ophthalmologist.

If you develop symptoms such as drowsiness, decreased consciousness and movement (stupor) or confusion, consult your doctor, who will decide whether to reduce the dose or stop treatment.

A small number of people treated with antiepileptics like vigabatrin have had thoughts of self-harm or suicide. If you have these thoughts at any time, contact your doctor immediately.

Children

There have been reports of movement disorders and abnormalities in magnetic resonance imaging (MRI) of the brain in young children treated for infant spasms (West syndrome). If you notice unusual movement disorders in your child, consult your doctor, who will decide whether to consider changing treatment.

Other medicines and VIGZIP

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines.

Tell your doctor if you are taking clonazepam, as concomitant use with Vigzip may increase the risk of sedation.

Vigzip should not be used in combination with other medicines that may have eye-related adverse effects.

Pregnancy, breast-feeding, and fertility

If you are pregnant or breast-feeding, think you may be pregnant, or plan to become pregnant, consult your doctor before using this medicine.

Do not take Vigzip during pregnancy unless your doctor tells you to. This medicine may cause problems to the fetus. However, do not stop treatment abruptly, as this may put the health of the mother and baby at risk.

Vigabatrin passes into breast milk. If you are breast-feeding, ask your doctor before using this medicine. You should not breast-feed during treatment.

Driving and using machines

Do not drive or operate machinery if your epilepsy is not controlled.

This medicine may cause symptoms such as drowsiness, dizziness, or changes in vision, and may reduce your reaction ability. These effects, as well as the disease itself, may make it difficult for you to drive vehicles or operate machinery. Therefore, do not drive, operate machinery, or engage in other activities that require special attention until your doctor assesses your response to this medicine.

Some patients taking this medicine have experienced visual disturbances that may affect their ability to drive or operate machinery. If you want to continue driving, you should undergo regular examinations (every six months) to rule out visual disturbances, even if you do not notice any changes in your vision.

Vigzip contains methyl parahydroxybenzoate (E 218) and propyl parahydroxybenzoate (E 216)

which may cause allergic reactions (possibly delayed).

3. How to take Vigzip

Follow the instructions for administration of this medicine exactly as indicated by your doctor. In case of doubt, consult your doctor or pharmacist.

It is essential to follow your doctor's instructions exactly. Never change the dose. The doctor prescribes the dose and adjusts it individually for each patient.

The recommended initial dose for adults is 1 g of vigabatrin (10 ml of solution) per day. However, your doctor may increase or decrease the dose depending on your response to treatment. The usual daily dose for adults is 2 to 3 g of vigabatrin (20 ml to 30 ml of solution). The maximum recommended dose is 3 g/day.

The daily dose can be taken as a single dose or divided into two doses.

If you are an elderly patient and/or have kidney problems, your doctor will prescribe a lower dose.

Pediatric use

Resistant partial epilepsy

In children, the dose is based on age and weight. The recommended initial dose for children is 40 milligrams per kilogram of body weight per day. The table below indicates the number of milliliters to be administered to a child depending on their body weight. Remember that this is only a guide. The child's doctor will decide if a slightly different dose is prescribed.

Children with infant spasms (West syndrome)

The recommended initial dose for infants with West syndrome (infant spasms) is 50 milligrams of vigabatrin per kilogram of body weight per day, although sometimes higher doses may be used.

Vigzip is for oral use

This medicine can be taken before or after meals

The pack contains an oral syringe (10 ml with graduations every 0.25 ml after the first 1.0 ml) and an adapter.

A full oral syringe (10 ml) is equivalent to 1,000 mg (1 g) of vigabatrin. The minimum volume that can be withdrawn is 1.0 ml (100 mg of vigabatrin). Volumes greater than 1.0 ml can be withdrawn in increments of 0.25 ml, which is equivalent to 25 mg of vigabatrin.

If you stop treatment with VIGZIP

Do not stop treatment prematurely without consulting your doctor first. If your doctor decides to stop your treatment, they will give you recommendations on how to gradually reduce the dose. Do not stop it abruptly, as this may cause your seizures to return.
