The name of your medicine is Gabapentin Medreich 100mg, 300mg or 400mg Capsules (called
gabapentin throughout this leaflet).
Gabapentin belongs to a group of medicines used:

to treat epilepsy,

to relieve long lasting pain caused by damage to the nerves (peripheral neuropathic pain).
To treat epilepsy: gabapentin is used to treat various forms of epilepsy in adults and children over
6 years old.
Your doctor will prescribe gabapentin if your current treatment is no longer fully controlling your epilepsy.
You should take gabapentin in addition to your current treatment.
If your doctor considers that it is necessary, gabapentin can also be used on its own.
To relieve peripheral neuropathic pain:
Peripheral neuropathic pain is a long lasting pain caused by damage to the nerves.
A variety of different diseases can cause this type of pain (primarily occurring in the legs and/or arms),
such as diabetes (high blood sugar) or shingles (disease caused by the varicella virus). These pains
may be felt as hot, burning, throbbing, shooting, stabbing, sharp, cramping, aching, tingling,
numbness, pins and needles etc.
Gabapentin is used to treat these long lasting pains.


Do not take gabapentin:

if you are allergic (hypersensitive) to the active substance of this medicine (gabapentin) or to any
of the other ingredients of this medicine (refer to section 6.Further information).
Take special care with gabapentin and check with your doctor or pharmacist before using this
medicine if:

You suffer from kidneys problems
A small number of people being treated with anti-epileptics such as gabapentin have had thoughts of
harming or killing themselves. If at any time you have these thoughts, immediately contact your doctor.
Important information about potentially serious reactions
A small number of people taking gabapentin get an allergic reaction or potentially serious skin reaction,
which may develop into more serious problems if they are not treated. You need to know the symptoms
to look out for while you are taking gabapentin.
Read the description of these symptoms in section 4 of this leaflet under ‘Tell your doctor straight away’.
Taking other medicines
Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines,
including medicines obtained without prescription.
If you are taking any medicines containing morphine, please tell your doctor or pharmacist as
morphine may increase the effect of gabapentin.
The absorption of gabapentin from the stomach may be reduced if you are taking any medicines used
to treat ulcer (antacids containing aluminium and magnesium) at the same time. It is therefore recommended
that gabapentin is taken at the earliest two hours after taking an antacid.

Taking Gabapentin Capsules with food and drink
Gabapentin can be taken with or without food.

Do not suddenly discontinue taking this medicine. The seizures may reappear, which could have
serious consequences for you and your baby.
Ask your doctor or pharmacist for advice before taking any medicine.
This is because gabapentin can pass into the mother’s milk. As the effect on the nursing infant is
unknown, it is not recommended to breast-feed your baby while using gabapentin.

treatment is stopped, it should be done gradually over a minimum of 1 week. If you stop taking
