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

The active ingredient is gabapentin.

Gabapentin 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). Your doctor will prescribe Gabapentina to help treat your epilepsy when your current treatment does not fully control the disease. You must take Gabapentina in combination with your current treatment unless otherwise instructed.Gabapentina 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 takeGabapentina:

• If you are allergic (hypersensitive) to gabapentina or to any of the other ingredients of this medication (listed in section 6).

• If you have kidney problems, your doctor may prescribe a different dosing regimen.
• If you are on hemodialysis (for removing waste products due to renal insufficiency), inform your doctor if you start feeling muscle pain and/or weakness.
• If you develop symptoms such as persistent stomach pain, vomiting, and nausea, inform your doctor immediately as they 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 medication, inform your doctor if you have ever abused or had dependence on alcohol, prescribed medications, or illegal drugs; you may have a higher risk of developing dependence on Gabapentina Normon.

Severe cases of abuse and dependence of gabapentina have been reported from post-marketing experience. Talk to your doctor if you have a history of abuse or dependence.

A small number of people taking antiepileptic medications such as Gabapentina have had thoughts of self-harm or suicide. If you experience these thoughts at any time, contact your doctor as soon as possible.

Important information about potentially severe reactions

Severe skin reactions associated with gabapentina use have been reported, including Stevens-Johnson syndrome, toxic epidermal necrolysis, and drug reaction with eosinophilia and systemic symptoms (DRESS). Stop taking gabapentina 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 these symptoms in section 4 of this prospectus“Contact your doctor immediately if you experience any of the following symptoms after taking this medication as they may be severe”

Muscle weakness, sensitivity, or pain, especially if you feel unwell or have a fever, could be due to an abnormal breakdown of muscle fibers, which 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 Gabapentina with other medications

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

Medications containing opioids such as morphine

If you are taking any medication containing opioids (such as morphine), inform your doctor or pharmacist as opioids may increase the effect of Gabapentina. Additionally, the combination of Gabapentina with opioids may cause symptoms such as drowsiness and/or decreased breathing.

Antacids for indigestion

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

Gabapentina:

- Gabapentina is not expected to interact with other antiepileptic medications or with the oral contraceptive pill.
