Dependence

Some people may become dependent on gabapentin (a need to keep takin the medicine).They may have withdrawal effects when they stop using Gabapentin (see section 3, “How to take Gabapentin” and “If you stop taking Gabapentin”).

If you have concerns that you may become dependent on Gabapentin, it is important that you consult your doctor

If you notice any of the following signs whilst taking Gabapentin, it could be a sign that you have become dependent.

• You feel you need to take this medicine for longer than advised by your prescriber
• You feel you need to take more than the recommended dose
• You are using the medicine for reasons other than prescribed
• You have made repeated, unsuccessful attempts to quit or control the use of the medicine
• When you stop taking the medicine you feel unwell, and you feel better once taking the medicine again.

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.

A small number of people taking epilepsy medicines like Gabapentin have had thoughts of harming or killing themselves. If at any time you have these thoughts, talk to your doctor straight away.

If any of the above apply to you (or you are not sure), talk to your doctor or pharmacist before taking Gabapentin.

Serious skin rashes including Steven-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 “Stop using Gabapentin and seek medical attention immediately if you notice any of the following symptoms”

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.

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines. 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.This includes medicines obtained without a prescription, including herbal medicines.This is because Gabapentin can affect the way some other medicines work. Also some other medicines can affect the way Gabapentin works.

In particular tell your doctor or pharmacist if you are taking medicines containing opioids (such as morphine), used for pain.This is because morphine may increase the effect of Gabapentin. In addition, combination of Gabapentin with opioids may cause symptoms like sleepiness, sedation, decrease in breathing, or death.

If Gabapentin and antacids containing aluminium and magnesium are taken at the same time, absorption of Gabapentin from the stomach may be reduced. It is therefore recommended that Gabapentin is taken at the earliest two hours after taking an antacid.

Gabapentin does not normally affect other medicines for epilepsy or the oral contraceptive pill.

Gabapentin may interfere with some laboratory tests, if you require a urine test tell your doctor or hospital that you are taking Gabapentin.

Gabapentin can be taken with or without food.

• If you are pregnant or think you may be pregnant, you must tell your doctor straight away and discuss possible risks the medicine you are taking might pose to your unborn baby.
• You should not stop your treatment without discussing this with your doctor.
• If you are planning to become pregnant you should discuss your treatment with your doctor or pharmacist as early as possible before you become pregnant.
• If you are breastfeeding or planning to breastfeed, ask your doctor or pharmacist for advice before taking this medicine.

Pregnancy

Gabapentin can be used during the first trimester of pregnancy if needed.

If you plan to become pregnant or if you are pregnant or think you may be pregnant, talk to your doctor straight away.

If you have become pregnant and you have epilepsy, it is important that you do not stop taking your medicine without first consulting your doctor, as this may worsen your illness.Worsening of your epilepsy may put you and your unborn child at risk.

In a study reviewing data from women in Nordic countries who took gabapentin in the first 3 months of pregnancy, there was no increased risk of birth defects or problems with the development of brain function (neurodevelopment disorders). However, babies of women who took gabapentin during pregnancy had an increased risk of low birth weight and preterm birth.

If used during pregnancy, gabapentin may lead to withdrawal symptoms in newborn infants.This risk might be increased when gabapentin is taken together with opioid analgesics (medicines for treatment of severe pain). 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.

Breast-feeding

Gabapentin is passed on through human milk.

Because the effect on the baby is unknown, it is not recommended to breast-feed while using Gabapentin.

Fertility

There is no effect on fertility in animal studies.

Ask your doctor or pharmacist for advice before taking any medicine.
