Vigabatrin is used together with other medicines to treat epilepsy (also known as fits or seizures).
Take Vigabatrin exactly as directed by your doctor or according to the instructions on the label. Do not take more or less than instructed by your doctor.
You may take Vigabatrin with or without food. Take it with plenty of water.
Vigabatrin is available as sachets or tablets.
If you are using the sachet, dissolve the contents in 10mL of water, fruit juice, infant formula or milk before taking. Drink the solution immediately after you dissolve it.
Vigabatrin must be taken regularly for it to be effective. Continue taking Vigabatrin even when you feel better. Vigabatrin is not a cure and you may need to take it long-term to keep your seizures under control. Do not stop taking Vigabatrin unless instructed otherwise as stopping it suddenly may worsen your condition.
Take the missed dose as soon as you remember. If it is almost time for your next dose, skip the missed dose and return to your normal dosing schedule.
DO NOT double a dose under any circumstances.
If you often forget to take your medicine, let your doctor and pharmacist know.
Inform your doctor if you have the following conditions:
- kidney disease
- eyesight problems or eye disorders
- history of mood disorders or mental illness
Let your doctor know if you are pregnant or breastfeeding.
For as long as you are being treated with Vigabatrin, you will need to have your eyes checked regularly. Your doctor will advise you about how often you need to have these tests.
Vigabatrin may cause dizziness, tiredness and drowsiness. If affected, do not drive or take part in any activity in which you need to be alert.
