What GABAPENTIN ASPEN is used for
GABAPENTIN ASPEN capsules contain gabapentin as the active ingredient.
GABAPENTIN ASPEN belongs to a group of medicines called anticonvulsants and is used to control epilepsy. It is also used in addition to current anti-epileptic therapy when the current treatment is no longer working as well. Epilepsy is a condition where you have repeated seizures (fits). There are many different types of seizures, ranging from mild to severe.
This medicine is also used to treat neuropathic pain, which is usually described as a shooting, stabbing or burning pain.
Anticonvulsants such as GABAPENTIN ASPEN are thought to work by controlling brain chemicals which send signals to nerves so that seizures are treated.
Ask your doctor if you have any questions about why GABAPENTIN ASPEN has been prescribed for you. Your doctor may have prescribed it for another reason.
There is no evidence that this medicine is addictive.
This medicine is available only with a doctor’s prescription.
It is not recommended for use in children under the age of 3 years to control epilepsy, as its safety and effectiveness in that age group have not been established. Also, the safety and effectiveness of GABAPENTIN ASPEN for the treatment of neuropathic pain in children under the age of 18 years have not been established.

How to take it
How much to take
Your doctor will tell you how many capsules you will need to take each day. This may depend on your age, your condition and whether or not you are taking any other medicines.
Your doctor may recommend that you start with a low dose and slowly increase the dose to the lowest amount needed to control your epilepsy/convulsions or neuropathic pain.
Follow all directions given to you by your doctor carefully. They may differ from the information contained in this leaflet.
How to take it
Swallow GABAPENTIN ASPEN whole with a full glass of water.
When to take it
Take your medicine at about the same time each day. Taking GABAPENTIN ASPEN at the same time each day will have the best effect. It will also help you remember when to take the capsules.
It does not matter if you take it before or after food.
If you forget to take it
If you have missed a dose by not more than 4 hours, take the dose as soon as you remember.
However, if you have missed a dose by more than 4 hours, you should skip the dose and then go back to taking your medicine as you would normally.
