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.
A small number of people being treated with antiepileptics such as gabapentin have had thoughts of harming themselves or committing suicide. If at any time you have these thoughts, contact your doctor as soon as possible.
Dependence
Some people may develop dependence (need to continue taking the medicine) on gabapentin. They may experience withdrawal symptoms when they stop taking this medicine (see section 3, "How to take Gabapentina Tarbis" and "If you stop taking Gabapentina Tarbis"). If you are concerned about developing dependence on gabapentin, it is important that you consult your doctor.
If you experience any of the following signs while taking gabapentin, it may indicate that you have developed dependence.
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.
Important information about potentially serious reactions
There have been reports of serious skin reactions 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 leaflet "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 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 the blood). If you experience any of these signs or symptoms, please contact your doctor immediately.
Other medicines and Gabapentina Tarbis
Tell your doctor or pharmacist if you are using, have recently used, or might use any other medicines. In particular, inform 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 containing opioids (such as morphine), inform your doctor or pharmacist, as opioids can increase the effect of gabapentin. Additionally, the combination of gabapentina with opioids can cause drowsiness, sedation, decreased breathing, or death.
Antacids for indigestion
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 gabapentina be taken at least two hours after taking an antacid.
Gabapentina Tarbis
Taking Gabapentina Tarbis with food
Gabapentina 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 this medicine during pregnancy, unless your doctor has told you to. An effective method of contraception 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. Therefore, whenever possible, you should try to take only one medicine for seizures during pregnancy and only under the advice of your doctor.
If taken during pregnancy, gabapentina 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 are planning to become pregnant while taking gabapentina. Do not stop taking this medicine suddenly, as this may cause seizures to return, which could have serious consequences for you and your baby.

Gabapentina, the active substance of Gabapentina Tarbis, passes into breast milk. Breastfeeding is not recommended while taking this medicine, as the effect on the baby is unknown.
Fertility
There are no effects on fertility in animal studies.
