1. What is Gabapentina Teva-ratiopharm and what is it used for

Gabapentina Teva-ratiopharm 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 Teva-ratiopharm is gabapentin.

Gabapentina Teva-ratiopharm is used to treat:

• Certain types of epilepsy (seizures that initially are 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 is not fully controlling the condition. You or your child (aged 6 years or older) should take gabapentin in addition to your current treatment unless told otherwise. Gabapentin can also be given alone in the treatment of adults and children over 12 years.

• 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 burning, shooting, aching, tingling, numbness, and pins and needles, etc.

2. What you need to know before you take Gabapentina Teva-ratiopharm

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

Warnings and precautions

Tell your doctor or pharmacist before you start taking gabapentin

• if you have kidney problems, your doctor may prescribe a different dosing schedule.
• if you are on haemodialysis (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, feel sick or being sick, contact your doctor immediately, as these can 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, prescribed drugs, or illegal drugs; you may have a higher risk of developing dependence on gabapentin.

Dependence

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

If you experience any of the following signs while taking gabapentin, 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 what it was prescribed for.
• 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 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 taking antiepileptics, such as gabapentin, have had thoughts of harming themselves or suicide. If at any time you have these thoughts, contact your doctor immediately.

Important information about potentially serious reactions

Severe skin reactions have been reported 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 leaflet"Contact your doctor immediately if you experience any of the following symptoms after taking this medicine, as they can be serious".

Muscle weakness, tenderness, or pain and especially if you feel unwell or have a fever, could be due to an abnormal breakdown of muscle tissue that 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 the blood). If you experience any of these signs or symptoms, please contact your doctor immediately.

Other medicines and Gabapentina Teva-ratiopharm

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 disorder.

Medicines containing opioids such as morphine

If you are taking any medicines that contain opioids (such as morphine), tell your doctor or pharmacist, as opioids can increase the effect of gabapentin.

Additionally, the combination of gabapentin with opioids may cause symptoms such as drowsiness, sedation, decreased breathing, or death.

Antacids for indigestion

If you take gabapentin at the same time as antacids that contain aluminium or magnesium, the absorption of gabapentin in the stomach may be reduced. Therefore, it is recommended that gabapentin be taken at least two hours after taking an antacid.

Gabapentina Teva-ratiopharm

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

Taking Gabapentina Teva-ratiopharm with food

This medicine can be taken with or without food.

Pregnancy, breastfeeding, and fertility

• If you are pregnant or think you may be pregnant, you must tell your doctor to assess the possible risks that the medicine you are taking may have on the fetus.
• Do not stop your treatment without first talking to your doctor.
• If you are planning to become pregnant, you should evaluate your treatment as soon as possible with your doctor or pharmacist before becoming pregnant.
• If you are breastfeeding or planning to breastfeed, ask your doctor or pharmacist for advice before taking this medicine.

Pregnancy

Gabapentin can be used during the first trimester of pregnancy if necessary.

If you are planning to become pregnant or are pregnant or think you may be pregnant, consult your doctor immediately.

If you become pregnant and have epilepsy, it is important that you do not stop taking your medicine without first talking to your doctor, as this can worsen your condition. Worsening of your epilepsy can put both you and your unborn baby at risk.

In a study that reviewed data from women in Nordic countries who took gabapentin in the first 3 months of pregnancy, there was no increased risk of birth defects or problems with brain development (neurodevelopmental disorders). However, babies of women who took gabapentin during pregnancy had a higher risk of low birth weight and premature birth.

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

If taken during pregnancy, gabapentin may cause withdrawal symptoms in newborns. This risk may be higher when gabapentin is taken with opioid painkillers (such as morphine).

Breastfeeding

Gabapentin, the active substance in this medicine, passes into breast milk. Breastfeeding is not recommended while taking gabapentin, as its effect on newborns is unknown.

Fertility

There are no effects on fertility in animal studies.

Driving and using machines

Gabapentina Teva-ratiopharm 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.
