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.

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 it may 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.

Use of Gabapentina Teva-ratiopharm with other medicines

Tell your doctor or pharmacist if you are taking, have recently taken, or might take any other medicines. In particular, inform 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 condition.

Medicines containing opioids such as morphine

If you are taking any medicine containing opioids (such as morphine), inform your doctor or pharmacist, as opioids can increase the effect of Gabapentina Teva-ratiopharm. Additionally, the combination of Gabapentina Teva-ratiopharm with opioids can cause drowsiness, sedation, decreased breathing, or death.

Antacids for digestion

If you take gabapentina at the same time as antacids containing aluminum and magnesium, the absorption of gabapentina in the stomach may be reduced. Therefore, it is recommended that this medicine be taken at least two hours after taking an antacid.

Gabapentina Teva-ratiopharm

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 Teva-ratiopharm 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 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 at the same time. Therefore, whenever possible, you should try to take only one medicine for seizures during pregnancy and only under the advice of your doctor.

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 (drugs for treating intense pain).

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