Product introduction

Viby Sachet may be taken with or without food. However, take it at the same time each day as this helps to maintain a consistent level of medicine in the body. If you have missed a dose, take it as soon as you remember it and finish the full course of treatment even if you feel better. Stopping the medication suddenly without talking to your doctor may cause a worsening of your condition.

Some common side effects of this medicine include blurred vision, joint pain, tremors, tiredness, upper respiratory tract infection, aggression, double vision, nystagmus (involuntary eye movement) and altered walking. It may lead to loss of vision also, therefore, it is better to get the eyesight checked before you start the treatment and regularly thereafter. It may also cause dizziness and sleepiness, so do not drive or do anything that requires mental focus until you know how this medicine affects you. Weight gain may occur in some cases but it can be controlled by having a healthy balanced diet and doing exercise.

Epilepsy/Seizures

Benefits of Viby Powder for Oral Solution

Infantile spasms
Infantile spasms or seizures (fits), occur in babies, that make muscles in the arms and legs stiff and bend the baby's head forward. Babies may also have slow development or loss of skills (like babbling, sitting, or crawling) if these spasms are left untreated. Viby Sachet helps stimulate release of those hormones in babies, that help to treat infantile spasms and also prevents its associated complications.

Epilepsy/Seizures
Viby Sachet slows down electrical signals in the brain that cause seizures (fits). It can also help reduce symptoms of seizures, such as confusion, uncontrollable jerking movements, loss of awareness, and fear or anxiety. This medicine can allow you to do some activities that you would otherwise be forbidden or scared to do (such as swimming and driving). It can take a few weeks for this medicine to work (because the dose has to be increased slowly) and during this time you may still have seizures. Therefore, do not stop using this medicine even if you feel well, until your doctor advises you to. Missing doses may trigger a seizure.

Frequently asked questions

Why has doctor asked me to get my vision tested? Can Viby Sachet affect vision?

Your doctor may get your vision checked at the start of treatment, 4 weeks after starting treatment, then after every 3 months during the treatment and 3-6 months after stopping the treatment.

My child was first prescribed Viby Sachet in powder form but now it has been changed to tablet. Will this have a lessened effect?

No, your doctor will adjust the dose of Viby Sachet tablets based on your child’s body weight and age. This will have the same effect as the powder.

Does Viby Sachet have psychiatric side effects? If yes, what are they?

The common psychiatric side effects of Viby Sachet include agitation, aggression, nervousness, irritability, depression, thought disturbance and paranoia (feeling suspicious without reason) and sleeplessness. These side effects are usually reversible when the dose is reduced or gradually discontinued.

What if someone accidentally swallows more than the recommended dose of Viby Sachet?

If you take more than the recommended dose of Viby Sachet, you should immediately consult your doctor or go to a nearby hospital. Possible symptoms of overdose include drowsiness or loss/depressed level of consciousness.

For how long do I need to take Viby Sachet? Can I stop taking it if I am symptom free?
