1. What is gabapentina cinfa and what is it used for

gabapentina cinfa belongs to a group of medicines used to treat epilepsy and peripheral neuropathic pain (long-lasting pain caused by damage to the nerves).

The active substance of gabapentina cinfa is gabapentin. Gabapentin is used to treat:

• Certain types of epilepsy (seizures that are initially limited to certain parts of the brain, whether or not the seizure spreads to other parts of the brain). Your doctor will prescribe gabapentina for you or your child aged 6 years or older to help treat your epilepsy when your current treatment does not fully control your condition.

You or your child aged 6 years or older should take gabapentina in combination with your current treatment unless otherwise indicated. Gabapentina can also be given as the only medicine in the treatment of adults and children over 12 years of age.

Peripheral neuropathic pain (long-lasting pain caused by damage to the nerves). There are various diseases that can cause peripheral neuropathic pain (mainly in legs and/or arms), such as diabetes or herpes. The sensation of pain can be described as heat, burning, throbbing pain, stabbing pain, sharp pain, spasms, continuous pain, tingling, numbness, and sensation of pins and needles, etc.

• if you are on hemodialysis (to remove waste products due to kidney failure), inform your doctor if you start to feel 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 medicine, inform your doctor if you have ever abused or been dependent on alcohol, prescription drugs, or illegal drugs; you may have a higher risk of developing dependence on gabapentina.

There have been reports of abuse and dependence on gabapentina from post-marketing experience. Talk to your doctor if you have a history of abuse or dependence.

A small number of people being treated with antiepileptics such as gabapentina have had thoughts of harming themselves or suicide. If at any time you have these thoughts, contact your doctor as soon as possible.

Dependence

Some people may develop dependence (need to continue taking the medicine) on gabapentina cinfa. They may have withdrawal symptoms when they stop taking gabapentina cinfa (see section 3, "How to take gabapentina cinfa" and "If you stop taking gabapentina cinfa"). If you are concerned about becoming dependent on gabapentina cinfa, it is important that you talk to your doctor.

If you experience any of the following signs while taking gabapentina cinfa, it may be indicative of dependence.

• You feel that you need to take the medicine for a longer period than prescribed.
• You feel that you need to take a higher dose than recommended.
• You are taking the medicine for reasons other than its 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.

Important information about potentially serious reactions

Severe skin reactions have been reported with the use of gabapentina, including Stevens-Johnson syndrome, toxic epidermal necrolysis, and drug rash with eosinophilia and systemic symptoms (DRESS). Stop taking gabapentina 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“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 on palpation, and especially if you feel unwell or have a fever, could be due to abnormal breakdown of muscle fibers, which can 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.

Other medicines and gabapentina cinfa

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 recently taken 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 can increase the effect of gabapentina. Additionally, the combination of gabapentina with opioids can cause symptoms such as drowsiness, sedation, decreased breathing, or death.

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. Therefore, it is recommended that gabapentina be taken at least 2 hours after taking an antacid.

Gabapentina:

• is not expected to interact with other antiepileptic medicines or with the oral contraceptive pill.
• may interfere with some laboratory tests, so if you need a urine test, inform your doctor or hospital about what you are taking.

Taking gabapentina cinfa with food

Gabapentina can be taken with or without food.

Pregnancy, breastfeeding, and fertility

If you are pregnant or breastfeeding, think you may be pregnant, or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Pregnancy

Do not take gabapentina during pregnancy, unless your doctor has told you to. An effective contraceptive method should be used in women of childbearing age.

There are no specific studies on the use of gabapentina in pregnant women, but in the case of other medicines used to treat seizures, there have been reports of an increased risk of harm to the developing baby, particularly when more than one medicine is used to treat seizures. Therefore, whenever possible, you should try to take only one medicine for seizures during pregnancy and only under the advice of your doctor.

Contact your doctor immediately if you become pregnant, think you may be pregnant, or are planning to become pregnant while taking gabapentina. Do not stop taking this medicine suddenly, as this may cause seizures to return, which could have serious consequences for you and your baby.

If you take gabapentina during pregnancy, gabapentina may cause withdrawal symptoms in newborns. This risk may be higher when gabapentina is taken with opioid painkillers (strong pain relief medicines).

Breastfeeding

Gabapentin, the active substance of gabapentina cinfa, passes into breast milk. Breastfeeding is not recommended while taking gabapentina, as the effect on the baby is unknown.

Fertility

There are no effects on fertility in animal studies.

Driving and using machines

Gabapentina may cause symptoms such as drowsiness, dizziness, or changes in vision and reduce your reaction ability. These effects, as well as the disease itself, may affect your ability to drive vehicles or operate machinery. Therefore, do not drive, operate machinery, or engage in other activities that require special attention until your doctor assesses your response to this medicine.
