1. What is Gabapentin Teva and what is it used for

Gabapentin Teva belongs to a group of medicines used to treat epilepsy and peripheral neuropathic pain (long-lasting pain caused by nerve damage).
The active substance of Gabapentin Teva is gabapentin.
Gabapentin Teva is used to treat:

• various forms of epilepsy (seizures initially limited to certain areas of the brain, which spread to the rest of the brain or not). Gabapentin Teva is prescribed to adults and children aged 6 years and older as an adjunctive therapy for epilepsy when the previously used treatment does not provide complete control of seizures. Gabapentin Teva should be taken as an adjunctive therapy for epilepsy in adults and children aged 6 years and older, unless the doctor advises otherwise. Gabapentin Teva can also be used as monotherapy in adults and children over 12 years of age.
• peripheral neuropathic pain (long-lasting pain caused by nerve damage). Peripheral (mainly occurring in the lower and/or upper limbs) neuropathic pain is caused by many different diseases, such as diabetes or shingles. Patients describe the pain they feel as burning, tingling, pulsating, piercing, stabbing, sharp, similar to that accompanying muscle cramps, as aching, tingling, numbness, etc.

2. Important information before taking Gabapentin Teva

When not to take Gabapentin Teva

• if you are undergoing hemodialysis (to remove metabolic products due to kidney failure), you should tell your doctor if you experience pain or muscle weakness,
• if you experience symptoms such as persistent abdominal pain, nausea, and vomiting, you should contact your doctor immediately, as they may be symptoms of acute pancreatitis,
• if you have neurological disorders, respiratory disorders, or are over 65 years of age; your doctor may prescribe a different dosage regimen,
• before starting to take this medicine, you should tell your doctor if you have ever abused or been dependent on alcohol, prescription drugs, or illegal addictive substances; this may mean that the risk of dependence on Gabapentin Teva is higher.

Dependence
Some people may develop dependence on Gabapentin Teva (the need for continuous use of the medicine). After stopping the use of Gabapentin Teva, they may experience withdrawal symptoms (see section 3, "How to take Gabapentin Teva" and "Stopping Gabapentin Teva"). If you are concerned that you may become dependent on Gabapentin Teva, it is essential to consult your doctor.
If, while taking Gabapentin Teva, you notice any of the following signs, it may indicate the development of dependence.

• You feel that you need to take the medicine for longer than your doctor prescribed
• You feel that you need to take a higher dose than prescribed
• You use the medicine for purposes other than prescribed
• You have made multiple, unsuccessful attempts to stop or control the use of the medicine
• After stopping the medicine, you feel unwell, and after taking it again, you feel better.

If you notice any of the above behaviors, you should talk to your doctor to discuss the best treatment option for you, including determining when it is appropriate to stop taking the medicine and how to do it safely.
A small number of people taking antiepileptic drugs containing gabapentin have thought about harming themselves or committing suicide. If you have ever had such thoughts, you should contact your doctor immediately.

Important information about potential serious side effects

In connection with the use of gabapentin, severe skin reactions, including Stevens-Johnson syndrome, toxic epidermal necrolysis, and drug reaction with eosinophilia and systemic symptoms (DRESS), have occurred. If any of the symptoms associated with severe skin reactions described in section 4 occur, you should stop taking gabapentin and contact your doctor immediately.
You should read the description of serious symptoms in section 4"You should 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, especially when accompanied by malaise and high fever, may be caused by abnormal muscle fiber breakdown, which can be life-threatening and lead to kidney problems. There may be a change in urine color and changes in blood test results (significantly elevated creatine phosphokinase levels in the blood). If you experience such subjective and objective symptoms, you should contact your doctor immediately.

Gabapentin Teva and other medicines

You should tell your doctor or pharmacist about all medicines you are currently taking or have recently taken, as well as any medicines you plan to take. You should especially tell your doctor (or pharmacist) about all medicines you have recently taken or are currently taking to treat seizures, sleep disorders, depression, anxiety disorders, or any other neurological or psychiatric disorders.
Medicines containing opioids, such as morphine
Patients taking medicines containing opioids (such as morphine) should inform their doctor or pharmacist, as opioids may enhance the effect of Gabapentin Teva.
Additionally, concomitant use of Gabapentin Teva and opioids may cause drowsiness, sedation, shallow breathing, or death.
Antacids for heartburn
In the case of concomitant use of Gabapentin Teva and antacids containing aluminum and magnesium, the absorption of Gabapentin Teva from the stomach may be limited. It is therefore recommended to take Gabapentin Teva at least 2 hours after taking an antacid.
Gabapentin Teva

• is not expected to interact with other antiepileptic medicines or oral contraceptives.
• may affect the results of some laboratory tests; if a urine test is performed, you should inform your doctor or hospital that you are taking Gabapentin Teva.

Pregnancy, breastfeeding, and fertility

• If you are pregnant or think you may be pregnant, you should contact your doctor immediately to discuss the potential risk to the unborn child associated with taking this medicine.
• You should not stop treatment without discussing it with your doctor.
• If you plan to have a child, you should discuss your treatment with your doctor or pharmacist as soon as possible before becoming pregnant.
• If you are breastfeeding or plan to breastfeed, you should contact your doctor or pharmacist before starting to take this medicine.

Pregnancy
Gabapentin Teva can be used during the first trimester of pregnancy if necessary.
If you are planning to become pregnant, are pregnant, or think you may be pregnant, you should contact your doctor immediately.
If you have become pregnant and have epilepsy, it is essential not to stop taking your medicine without first consulting your doctor, as this may worsen your condition. The severity of epilepsy may pose a risk to you and your unborn child.
In a study involving data from Scandinavian women who took gabapentin during the first 3 months of pregnancy, no increased risk of birth defects or developmental problems (neurodevelopmental disorders) was found. However, in children of women who took gabapentin during pregnancy, there was an increased risk of low birth weight and premature birth.
Gabapentin may cause withdrawal symptoms in newborns. This risk may be increased when gabapentin is taken with opioid painkillers (medicines used to treat severe pain).
If you become pregnant, think you may be pregnant, or plan to become pregnant while taking Gabapentin Teva, you should contact your doctor immediately. You should not suddenly stop taking this medicine, as it may lead to withdrawal seizures, which can have serious consequences for both you and your child.
Breastfeeding
Gabapentin, the active substance of Gabapentin Teva, passes into breast milk. Since it is not known what effect it has on the breastfed child, breastfeeding is not recommended while taking Gabapentin Teva.
Fertility
In animal studies, no effect on fertility has been found.

Driving and using machines

Gabapentin Teva may cause dizziness, drowsiness, and fatigue. Before you start driving or operating complex machines, or performing other potentially hazardous activities, you should wait until you know how this medicine affects you.
