1. What is Gabapentina Combix and what it is used for

This medicinal product contains the active substance gabapentin. Gabapentin belongs to a group of medicines used to treat epilepsy and peripheral neuropathic pain (long-lasting pain caused by damage to the nerves).

Gabapentina 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 the condition. You or your child aged 6 years or older should take gabapentina in combination with your current treatment unless told otherwise. 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, shooting, stabbing, sharp, spasms, continuous, tingling, numbness, and prickling, etc.

2. What you need to know before you take Gabapentina Combix

Warnings and precautions

• if you are on hemodialysis (to remove waste products due to kidney failure), tell your doctor if you start to feel muscle pain and/or weakness
• if you develop symptoms such as persistent stomach pain, vomiting, and nausea, tell 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, tell 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 Combix.

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 Combix. They may experience withdrawal symptoms when they stop taking Gabapentina Combix (see section 3, "How to take Gabapentina Combix" and "If you stop taking Gabapentina Combix"). If you are concerned about developing dependence on Gabapentina Combix, it is important that you talk to your doctor.

If you experience any of the following signs while taking Gabapentina Combix, it may indicate that you have developed 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 prescribed.
• you have tried to stop taking the medicine or control how you take it several times 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, tenderness, or pain 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.

Children and adolescents

The long-term effects (more than 36 weeks) of gabapentina treatment on learning ability, intelligence, and development in children and adolescents have not been adequately investigated. Therefore, the benefits of prolonged therapy should be weighed against the potential risks.

Other medicines and Gabapentina Combix

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 that contains opioids (such as morphine), tell your doctor or pharmacist, as opioids can increase the effect of gabapentina. Additionally, the combination of gabapentina with opioids may cause drowsiness, sedation, decreased breathing, or death.

Antacids for indigestion

If you take gabapentina at the same time as antacids that contain aluminum and magnesium, the absorption of gabapentina in the stomach may be reduced. Therefore, it is recommended that gabapentina be taken at least two 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, tell your doctor or hospital what you are taking.

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 of the use of gabapentina in pregnant women, but with 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 plan 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, it may cause withdrawal symptoms in newborns. This risk may be higher when gabapentina is taken with opioid painkillers.

Breastfeeding

Gabapentina 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 dizziness, drowsiness, and fatigue. Do not drive, operate heavy machinery, or engage in other potentially hazardous activities until you know whether this medicine affects your ability to perform these activities.
