1. What Gabapentin Morningside Capsules are and what they are used for

This medicine has been prescribed for you for treating epilepsy and peripheral neuropathic pain.

It contains gabapentin which belongs to a class of medicines called gabapentinoids.

This medicine has been prescribed to you and should not be given to anyone else.

Gabapentinoids can cause dependence, tolerance and addiction, and you may get withdrawal symptoms if you stop taking it or reduce the dose suddenly. Your prescriber should have explained how long you will be taking it for, when it is appropriate to stop and how to do this safely. When your treatment is stopped, it is usually done gradually over a period which is specific to you and may occur over a period of weeks to months. If this medicine is being used for the treatment of epilepsy you must continue to take it as prescribed by your doctor.

Gabapentin is used to treat:

  • Various forms of epilepsy (seizures that are initially limited to certain parts of the brain, whether the seizure spreads to other parts of the brain or not). Your doctor will prescribe Gabapentin Morningside Capsules for you or your child 6 years of age and older to help treat your epilepsy when your current treatment is not fully controlling your condition. You or your child 6 years of age and older should take Gabapentin Morningside Capsules in addition to your current treatment unless told otherwise. Gabapentin Morningside Capsules can also be used on its own to treat adults and children over 12 years of age.
  • Peripheral neuropathic pain (long lasting pain caused by damage to the nerves). A variety of different diseases can cause peripheral neuropathic pain (primarily occurring in the legs and/or arms), such as diabetes or shingles. Pain sensations may be described as hot, burning, throbbing, shooting, stabbing, sharp, cramping, aching, tingling, numbness, pins and needles etc..

2. What you need to know before you take

  • if you are on haemodialysis (to remove waste products because of kidney failure), tell your doctor if you develop muscle pain and/or weakness
  • 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)
  • if you have nervous system disorders, respiratory disorders, or you are more than 65 years old, your doctor may prescribe you a different dosing regimen
  • before taking this medicine, tell your doctor if you have ever abused or been dependent on alcohol, prescription medicines or illegal drugs; it may mean you have a greater risk of becoming dependent on Gabapentin Morningside Capsules
  • are or have ever been addicted to opioids, alcohol, prescription medicines, or illegal drugs, or if you have ever had a history of struggling to control your alcohol or drug intake
  • have previously suffered from withdrawal symptoms such as agitation, anxiety, shaking or sweating, when you have stopped taking alcohol or drugs
  • feel you need to take more of Gabapentin Morningside Capsules to get the same level of symptom control, this may mean you are developing tolerance to the effects of this medicine or are becoming addicted to it. Speak to your prescriber who will discuss your treatment and may change your dose or switch you to an alternative medication
  • if you have myasthenia gravis (a disease causing muscle weakness) because this medicine may make your symptoms worse.

Taking this medicine regularly, particularly for a long time, can lead to physical dependence and addiction. Your prescriber should have explained how long you will be taking it for and, when it is appropriate to stop, how to do this safely. When your treatment is stopped, it is usually done gradually over a period which is specific to you and may occur over a period of weeks to months.

Physical dependence and addiction can cause withdrawal symptoms when you stop taking this medicine. Withdrawal symptoms can include:

  • Trouble sleeping, headache, nausea, feeling anxious, diarrhoea, flu-like symptoms, convulsions, nervousness, depression, thoughts of harming or killing yourself, pain, sweating and dizziness.

Your prescriber will discuss with you how to gradually reduce your dose before stopping the medicine. It is important that you do not stop taking the medicine suddenly as you will be more likely to experience withdrawal symptoms. Your prescriber will ensure that your plan for stopping treatment is tailored to you and can be adapted according to your needs and experience of any withdrawal symptoms.

Gabapentinoids should only be used by those they are prescribed for. Do not give your medicine to anyone else. Taking higher doses or more frequent doses of gabapentinoids, may increase the risk of addiction. Overuse and misuse can lead to overdose and/or death. 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.

Dependence

Some people may become dependent on Gabapentin Morningside Capsules (a need to keep taking the medicine). They may have withdrawal effects when they stop using Gabapentin Morningside Capsules or reduce the dose (see section 3, “How to take Gabapentin Morningside Capsules” and “If you stop taking Gabapentin Morningside Capsules”). If you have concerns that you may become dependent on Gabapentin Morningside Capsules, it is important that you consult your doctor.

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

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 discolouration 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.

Other medicines and Gabapentin Morningside Capsules

Tell your doctor or pharmacist if you are taking, have recently taken or might take 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. 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. In addition, combination of Gabapentin with opioids may cause symptoms like sleepiness, sedation, decrease in breathing, or death.

Antacids for indigestion

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

  • are not expected to interact with other antiepileptic drugs or the oral contraceptive pill
  • may interfere with some laboratory tests, if you require a urine test tell your doctor or hospital what you are taking.

Gabapentin Morningside Capsules with food

Gabapentin Morningside Capsules can be taken with or without food.

Pregnancy, breast-feeding and fertility

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

Pregnancy

Gabapentin Morningside Capsules can be taken during the first trimester of pregnancy, unless you are told otherwise by your doctor.

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.

Some medicines used to treat seizures 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.

Contact your doctor immediately if you become pregnant, think you might be pregnant or are planning to become pregnant while taking Gabapentin Morningside Capsules. 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. 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 (drugs for treatment of severe pain).

Breast-feeding

Gabapentin, the active substance of Gabapentin Morningside Capsules, is passed on through human milk. Because the effect on the baby is unknown, it is not recommended to breast-feed while using Gabapentin Morningside Capsules.

Fertility

There is no effect on fertility in animal studies.

Driving and using machines

Gabapentin Morningside Capsules may produce dizziness, drowsiness and tiredness. You should not drive, operate complex machinery or take part in other potentially hazardous activities until you know whether this medication affects your ability to perform these activities.

Gabapentin Morningside Capsules contain lactose
