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

Gabapentina Sandoz 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 in Gabapentina Sandoz is gabapentina.

Gabapentina Sandoz 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 is no longer controlling your condition. You or your child aged 6 years or older should take gabapentina in addition to your current treatment unless otherwise directed. Gabapentina can also be given as the only medicine to treat 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 the legs and/or arms), such as diabetes or herpes. The sensation of pain can be described as heat, burning, throbbing, shooting, stabbing, acute, spasms, continuous, tingling, numbness, and pinching, etc.

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

Do not takeGabapentinaSandoz

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

Warnings and precautions

Talk to your doctor or pharmacist before taking gabapentina:

• if you have kidney problems, your doctor may prescribe a different dosage regimen,
• if you are on hemodialysis (to remove waste products due to kidney failure), tell your doctor if you experience muscle pain and/or weakness,
• if you develop symptoms such as persistent stomach pain, vomiting, and nausea, tell your doctor immediately as these can be symptoms of acute pancreatitis (inflamed pancreas),
• if you have nervous system disorders, respiratory disorders, or if you are over 65 years old, your doctor may prescribe a different dosage regimen,
• 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.

Dependence

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

If you experience any of the following signs while taking gabapentina, 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 its prescription.
• 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.

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

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 can be serious".

Muscle weakness, sensitivity, or pain on palpation, and especially if you feel unwell or have a fever, could be due to abnormal muscle fiber breakdown, 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 Sandoz

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 medicines 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 can cause symptoms such as drowsiness and/or decreased breathing.

Antacids for digestion

If you take gabapentina at the same time as antacids that contain aluminum or 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 Sandoz:

• 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.

TakingGabapentinaSandozwith food

Gabapentina Sandoz 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 other medicines used to treat seizures have been reported to increase the risk of harm to the developing baby, particularly when used at the same time as more than one medicine to treat seizures. If you take gabapentina during pregnancy, it may cause withdrawal symptoms in newborns. This risk may be higher when gabapentina is taken with opioid analgesics (drugs for treating intense pain). 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 can cause your seizures to happen more often, which could have serious consequences for you and your baby.

Breastfeeding

Gabapentina, the active substance in Gabapentina Sandoz, passes into breast milk. Breastfeeding is not recommended while taking Gabapentina Sandoz, as the effect on the baby is unknown.

Fertility

There are no effects on fertility in animal studies.

Driving and using machines

Gabapentina Sandoz can 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.

Gabapentina Sandoz contains sodium

This medicine contains less than 1 mmol of sodium (23 mg) per capsule, which is essentially "sodium-free".

Doses higher than recommended may lead to an increase in side effects, including loss of consciousness, dizziness, double vision, difficulty speaking, numbness, and diarrhea. In case of overdose or accidental ingestion, consult your doctor or pharmacist immediately or call the Toxicology Information Service, phone 915 620 420, indicating the medicine and the amount taken, or go to the emergency department of the nearest hospital. Bring any capsules you have not taken, along with the packaging and leaflet, so that the hospital can easily identify the medicine you have taken.

If you forget to take a dose, take it as soon as you remember, unless it is time for your next dose. Do not take a double dose to make up for forgotten doses.

If you stop takingGabapentinaSandoz

Do not stop taking gabapentina suddenly. If you want to stop taking gabapentina, talk to your doctor first. Your doctor will tell you how to proceed. If you are going to stop treatment, it should be done gradually over a minimum of one week. You should know that you may experience certain side effects, called withdrawal syndrome, after stopping short-term or long-term treatment with gabapentina. These include seizures, anxiety, difficulty sleeping, feeling unwell (nausea), pain, sweating, tremors, headache, depression, abnormal sensation, dizziness, and general feeling of discomfort. These effects usually occur within the first 48 hours after stopping treatment with gabapentina. If you experience this withdrawal syndrome, you should contact your doctor.
