Gabapentin capsules, hard (called Gabapentin capsules in the rest of this leaflet) belong to a group of medicines used to treat epilepsy and peripheral neuropathic pain (long lasting pain caused by damage to the nerves).
Gabapentin capsules are used to treat:
Talk to your doctor or pharmacist before taking Gabapentin capsules:
Cases of abuse and dependence have been reported for gabapentin from the post-marketing experience. Talk to your doctor if you have a history of abuse or dependence. 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.
Some people may become dependent on Gabapentin Capsules (a need to keep taking the medicine). They may have withdrawal effects when they stop using Gabapentin Capsules (see section 3, "How to take Gabapentin Capsules" and "If you stop taking Gabapentin Capsules"). If you have concerns that you may become dependent on Gabapentin Capsules, it is important that you consult your doctor.
If you notice any of the following signs whilst taking Gabapentin Capsules, it could be a sign that you have become dependent.
If you notice any of these, speak to your doctor to discuss the best treatment pathway for you, including when it is appropriate to stop and how to do this safely
Serious skin rashes including Stevens-Johnson syndrome, toxic epidermal necrolysis and drug reaction with eosinophilia and systemic symptoms (DRESS) have been reported in association with gabapentin. Stop using gabapentin and seek medical attention immediately if you notice any of the symptoms related to these serious skin reactions described in section 4.
Read the description of these symptoms in section 4 of this leaflet under 'Contact your doctor immediately if you experience any of the following symptoms after taking this medicine as they can be serious'
Muscle weakness, tenderness or pain and particularly, if at the same time, you feel unwell or have a high temperature it may be caused by an abnormal muscle breakdown which can be life-threatening and lead to kidney problems. You may also experience discoloration of your urine, and a change in blood test results (notably blood creatine phosphokinase increased). If you experience any of these signs or symptoms, please contact your doctor immediately.
Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines, including medicines obtained without a prescription. In particular, tell your doctor (or pharmacist) if you are taking or have been recently taking any medicines for convulsions, sleeping disorders, depression, anxiety, or any other neurological or psychiatric problems.
Medicines containing opioids such as morphine.
If you are taking any medicines containing opioids (such as morphine), please tell your doctor or pharmacist as opioids may increase the effect of Gabapentin capsules. In addition, combination of Gabapentin capsules with opioids may cause sleepiness, sedation, decrease in breathing, or death.
Antacids for indigestion
If Gabapentin capsules and antacids containing aluminium and magnesium are taken at the same time, absorption of Gabapentin capsules from the stomach may be reduced. It is therefore recommended that Gabapentin capsules are taken at the earliest two hours after taking an antacid.
Gabapentin capsules:
Gabapentin capsules with food - Gabapentin capsules can be taken with or without food.
Pregnancy Gabapentin capsules should not be taken during pregnancy, unless you are told otherwise by your doctor. Effective contraception must be used by women of child-bearing potential.
If used during pregnancy, gabapentin may lead to withdrawal symptoms in newborn infants. This risk might be increase when gabapentin is taken together with opioid analgesics (drugs for treatment of severe pain).
There have been very few studies specifically looking at the use of gabapentin in pregnant women. More research is needed to better understand the safety of use of gabapentin during pregnancy and whether it is associated with an increased risk of harm to the unborn child.
Some medicines used to treat epilepsy have reported an increased risk of harm to the developing baby, particularly when more than one seizure medication is taken at the same time. This means that where possible, your doctor should consider using one epilepsy medicine to control your epilepsy.

Do not suddenly discontinue taking this medicine as this may lead to a breakthrough seizure, which could have serious consequences for you and your baby.
