1 What Gabapentin capsules are and what they are used for

Gabapentin capsules belong to a group of medicines used to treat:

  • various forms of epilepsy – Gabapentin capsules can be used on their own in adults and children aged 12 years and over or in combination with other medicines to treat epilepsy in adults and children aged 6 years and over.
  • peripheral neuropathic pain - This is long lasting pain caused by damage to the nerves.

2 What you need to know before you take Gabapentin capsules

Do not take Gabapentin capsules

  • if you are allergic (hypersensitive) to gabapentin or any of the other ingredients of Gabapentin capsules (see section 6).

Warnings and precautions

Talk to your doctor, pharmacist or nurse before taking Gabapentin capsules

  • if you suffer from kidney problems your doctor may prescribe a different dosing schedule
  • if you suffer with different types of seizures including absences.
  • if you develop signs such as persistent stomach pain, feeling sick and being sick contact your doctor immediately as these may be symptoms of acute pancreatitis (an inflamed pancreas)

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.

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 these symptoms to look out for while you are taking gabapentin.

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’

Other medicines and Gabapentin capsules

Please tell your doctor or pharmacist if you are taking or have recently taken any other medicines, including medicines obtained without a prescription. In particular:

  • 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 symptoms like sleepiness and/or decrease in breathing.
  • antacids containing aluminium and magnesium (used to reduce stomach acid)- if 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 least two hours after taking an antacid.

Urine Tests

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

Pregnancy, breastfeeding and fertility

Pregnancy

Gabapentin capsules should not be taken during pregnancy, unless advised by your doctor.

Contact your doctor immediately if you become pregnant, think you might be pregnant or are planning to become pregnant while taking Gabapentin capsules.

Other medicines used to treat seizures may increase the risk of harm to the foetus, particularly when more than one seizure medication is taken at the same time. Therefore, whenever possible and only under the advice of your doctor, you should try to take only one seizure medication during pregnancy.

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

Breast-feeding

If you are taking Gabapentin capsules, do not breastfeed, unless advised to by your doctor, as this medicine will pass into breast milk and may harm the baby.

Fertility

There is no effect on fertility in animal studies.

Driving and using machines

When taking Gabapentin capsules you may become drowsy, dizzy or feel tired, especially at the start of treatment or after a dose increase. Make sure you are not affected before driving or operating machinery.

Gabapentin capsules contain lactose

The capsules contain lactose monohydrate. If your doctor has told you that you have an intolerance to some sugars, contact your doctor before taking this medicine.

3 How to take Gabapentin capsules

Always take Gabapentin capsules exactly as your doctor has told you. If you are not sure, check with your doctor or pharmacist.

Gabapentin capsules are usually taken three times a day (morning, afternoon and evening). Always swallow the capsules whole with plenty of water, with or without food.

Your doctor will determine what dose is appropriate for you. If you are an elderly patient (over 65 years old), have kidney disease or are having haemodialysis you should take Gabapentin capsules as prescribed by your doctor.

Continue taking Gabapentin capsules until your doctor tells you to stop.

    Adults and children aged 12 years or over:
    The usual starting dose is between 300mg and 900mg each day. The dose may then be increased gradually to a maximum of 3600mg each day.
    Children aged 6 years and above:
    The dose depends on the body weight of your child. The treatment is started with a low initial dose which is gradually increased over a period of about 3 days. The usual dose to control epilepsy is 25-35mg per kg per day.
    Gabapentin capsules are not recommended for use in children below 6 years of age.

If you take more Gabapentin capsules than you should

If you or someone else accidentally takes too many capsules, or if you think a child has swallowed any, contact your doctor or go to your nearest hospital casualty department immediately. As Gabapentin capsules may make you drowsy, it is recommended that you ask someone else to drive you to the doctor or hospital, or that you call an ambulance. Symptoms of an overdose are dizziness, double vision, slurred speech, drowsiness or tiredness, loss of consciousness and mild diarrhoea. Overdose of gabapentin, particularly in combination with other CNS depressant medications, may result in coma.

If you forget to take Gabapentin capsules

If you miss a dose, take it as soon as you remember, unless it is time for your next dose. Do not take a double dose to make up for a forgotten dose.
