Neurontin belongs to a group of medications used to treat epilepsy and peripheral neuropathic pain (chronic pain caused by nerve damage).

The active ingredient of Neurontin is gabapentin.

Neurontin is used to treat

- Certain types of epilepsy (seizures initially limited to certain parts of the brain, whether the seizure spreads to other parts of the brain or not). The doctor treating you or your child aged 6 years or older will prescribe Neurontin to help treat epilepsy when the current treatment does not fully control the disease. You or your child aged 6 years or older must take Neurontin in combination with the current treatment unless otherwise indicated.Neurontin can also be administered as a single medication in the treatment of adults and children over 12 years old.

- Peripheral neuropathic pain(chronic pain caused by nerve damage). There are various diseases that can cause peripheral neuropathic pain (mainly in legs and/or arms), such as diabetes or herpes. The pain sensation could be described as heat, burning, pulsating pain, stabbing pain, sharp pain, acute pain, spasms, continuous pain, tingling, numbness, and pins and needles etc.

Do not takeNeurontin

• if you are allergic (hypersensitive) to gabapentin or any of the other ingredients of this medicine (listed in section 6).

• if you are on haemodialysis (for waste removal due to renal insufficiency), inform your doctor if you start to feel muscle pain and/or weakness.
• if you develop persistent stomach pain, vomiting, and nausea, inform your doctor immediately as these may be symptoms of acute pancreatitis (inflamed pancreas).
• if you have a nervous system disorder or a respiratory disorder or if you are over 65 years old, your doctor may prescribe a different dose.
• before taking this medicine, inform your doctor if you have ever abused or had dependence on alcohol, prescribed medicines, or illegal drugs; you may have a higher risk of developing dependence on Neurontin.

Dependence

Some people may develop dependence (need to continue taking the medicine) on Neurontin. They may experience withdrawal symptoms when they stop taking Neurontin (see section 3, "How to take Neurontin" and "If you interrupt treatment with Neurontin"). If you are concerned about developing dependence on Neurontin, it is essential to consult your doctor.

If you experience any of the following signs while taking Neurontin, it may be indicative that you have developed dependence.

- you feel the need to take the medicine for longer than prescribed.

- you feel the need to take a higher dose than recommended.

- you are taking the medicine for reasons other than your prescription.

- you have tried several times to stop taking the medicine or control how you take it, without success.

- when you stop taking the medicine, you feel unwell and feel better when you take it again.

If you notice any of the above, talk to your doctor to decide on the best course of treatment for you, including when it is appropriate to stop treatment and how to do it safely.

A small number of people taking antiepileptic medicines such as Neurontin have had thoughts of harming themselves or suicide. If you experience these thoughts at any time, contact your doctor as soon as possible.

Important information about potentially serious reactions

Severe skin reactions associated with gabapentin use have been reported, including Stevens-Johnson syndrome, toxic epidermal necrolysis, and drug reaction with eosinophilia and systemic symptoms (DRESS). Stop taking gabapentin and seek medical attention immediately if you notice any of the symptoms related to these severe skin reactions described in section 4.

Read the description of severe symptoms in section 4 of this leaflet“Contact your doctor immediately if you experience any of the following symptoms after taking this medicine as they may be serious”

Muscle weakness, sensitivity, or pain, especially if you feel unwell or have a fever, could be due to an abnormal breakdown of muscle fibers that may lead to kidney problems and put your life at risk. You may also experience urine discoloration, and changes in blood test results (significant increase in creatine phosphokinase in blood). If you experience any of these signs or symptoms, please contact your doctor immediately.

Use of Neurontin with other medicines

Inform your doctor or pharmacist if you are using, have used recently, or may need to use any other medicine. Especially, inform your doctor (or pharmacist) if you are taking or have taken recently any medicine for seizures, sleep disorders, depression, anxiety, or any other neurological or psychiatric problem.

Medicines containing opioids such as morphine

If you are taking any medicine containing opioids (such as morphine), inform your doctor or pharmacist as opioids may increase the effect of Neurontin. Additionally, the combination of Neurontin with opioids may cause drowsiness, sedation, decreased breathing, or death.

Antacids for indigestion

If you take Neurontin at the same time as antacids containing aluminum and magnesium, the absorption of Neurontin in the stomach may be reduced. It is recommended that Neurontin be taken at least two hours after taking an antacid.

Neurontin

- it is not expected to interact with other antiepileptic medicines or with the oral contraceptive pill.

- it may interfere with some laboratory tests, so if you need a urine test, inform your doctor or the hospital about what you are taking.

Taking Neurontin with food

Neurontin can be taken with or without food.

Pregnancy, breastfeeding, and fertility

• If you are pregnant or think you may be pregnant, you must inform your doctor immediately to assess the potential risks the medicine you are taking may pose to the fetus.
• You should not stop your treatment without consulting your doctor first.
• If you are planning to become pregnant, you should evaluate your treatment as soon as possible with your doctor or pharmacist before becoming pregnant.
• If you are breastfeeding or planning to breastfeed, consult your doctor or pharmacist before taking this medicine.

Pregnancy

Neurontin can be used during the first trimester of pregnancy if necessary.

If you plan to become pregnant or are pregnant or think you may be pregnant, consult your doctor immediately.

If you become pregnant and have epilepsy, it is essential not to stop taking your medicine without consulting your doctor first, as this may worsen your condition. Stopping your treatment may put both you and your unborn baby 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 brain development (neurodevelopmental disorders). However, babies of women who took gabapentin during pregnancy had a higher risk of low birth weight and premature birth.

If taken during pregnancy, gabapentin may cause withdrawal symptoms in newborns. This risk may be higher when gabapentin is taken concomitantly with opioid analgesics (pain medicines).

Contact your doctor immediately if you become pregnant, think you may be pregnant, or plan to become pregnant while taking Neurontin. Do not stop taking this medicine abruptly as this may cause an anticipation of seizures, which could have serious consequences for both you and your baby.
