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 of Gabapentina Sandoz 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 gabapentin for you or your child aged 6 years or older to help treat epilepsy when your current treatment does not fully control the condition. You or your child aged 6 years or older should take gabapentin in combination with your current treatment unless told otherwise. Gabapentin can also be given as the only medicine to treat adults and children over 12 years of age.

• Peripheral neuropathic pain in adults (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 pain, shooting pain, stabbing pain, acute pain, spasms, continuous pain, tingling, numbness, and a feeling of pins and needles, etc.

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

Do not take Gabapentina Sandoz

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

Warnings and precautions

Consult your doctor or pharmacist before taking Gabapentina Sandoz.

• 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), 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 these may be symptoms of acute pancreatitis (inflammation of the 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,
• if you have ever abused or been dependent on alcohol, prescription drugs, or illegal drugs; this may mean you have a higher risk of developing dependence on Gabapentina Sandoz.

There have been reports of abuse and dependence on gabapentin 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 Sandoz. They may experience withdrawal symptoms when they stop taking Gabapentina Sandoz (see section 3, "How to take Gabapentina Sandoz" and "If you stop taking Gabapentina Sandoz"). If you are concerned about developing dependence on Gabapentina Sandoz, it is important that you consult your doctor.

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

• You feel that you need to take the medicine for longer 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 what is 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 gabapentin have had thoughts of harming themselves or committing suicide. If at any time you present these thoughts, contact your doctor immediately.

Important information about potentially serious reactions

Severe skin reactions have been reported associated with the use of gabapentin, including Stevens-Johnson syndrome, toxic epidermal necrolysis, and drug rash with eosinophilia and systemic symptoms (DRESS). Stop taking gabapentin 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 leafletin the subsection “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, 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 discoloration of the urine and changes in blood test results (significant increase in creatine phosphokinase in the 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 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), inform your doctor or pharmacist, as opioids can increase the effect of gabapentin. Additionally, the combination of gabapentin with opioids can cause symptoms such as drowsiness and/or decreased breathing.

Antacids for indigestion

If you take gabapentin at the same time as antacids that contain aluminum and magnesium, the absorption of gabapentin in the stomach may be reduced. Therefore, it is recommended that gabapentin 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 Sandoz with 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 gabapentin 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 gabapentin 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 gabapentin during pregnancy, it may cause withdrawal symptoms in newborns. This risk may be higher when gabapentin is taken with opioids (pain-relieving medicines). 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 gabapentin. Do not stop taking this medicine suddenly, as this may cause your seizures to return, which could have serious consequences for you and your baby.

Breastfeeding

Gabapentin, the active substance of Gabapentina Sandoz, passes into breast milk. Breastfeeding is not recommended while taking gabapentin, as its 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.

Gabapentina Sandoz contains soy lecithin and sodium

This medicine contains soy lecithin. It should not be used in case of peanut or soy allergy.

This medicine contains less than 1 mmol of sodium (23 mg) per film-coated tablet; this is essentially “sodium-free”.

3. How to take Gabapentina Sandoz

Your doctor will determine the dose that is right for you.

Epilepsy, the recommended dose is:

The dose is usually given by taking the tablets, divided into 3 equal doses per day, usually one in the morning, one at noon, and one at night.

Call your doctor or go to the emergency department of the nearest hospital if you take more gabapentin than your doctor has prescribed. Bring any tablets 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 Gabapentina Sandoz

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.

These include seizures, anxiety, difficulty sleeping, feeling unwell (nausea), pain, sweating, tremors, headache, depression, abnormal sensation, dizziness, and a general feeling of being unwell. These effects usually occur within the first 48 hours after stopping treatment with gabapentin. If you experience this withdrawal syndrome, you should contact your doctor.
