Additional information about potentially serious reactions

Severe skin reactions have been reported in association 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 immediate medical attention 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 in “Call your doctor immediately if you experience any of the following symptoms after taking this medication, as it may be serious”.

Use of other medications

Tell your doctor or pharmacist if you are using or have recently used other medications, including those obtained without a prescription. Especially, inform your doctor (or pharmacist) if you are taking or have recently taken any medication for seizures, sleep disorders, depression, anxiety, or any other neurological or psychiatric problem.

If you are taking any medication that contains morphine, inform your doctor or pharmacist, as morphine may increase the effect of Gabapentina Alter.

Gabapentina Alter may interfere with some laboratory tests, so if you need a urine test, inform your doctor or hospital that you are taking Gabapentina Alter.

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

Pregnancy and breastfeeding

Consult your doctor or pharmacist before taking any medication.

There are no specific studies on the use of gabapentina in pregnant women, but with other medications used to treat seizures, an increased risk of fetal damage has been reported, particularly when more than one medication is used to treat seizures. Therefore, whenever possible and only under the advice of your doctor, you should try to take only one medication for seizures during pregnancy.

If taken during pregnancy, gabapentina may cause withdrawal symptoms in newborns. This risk may be higher when gabapentina is taken with opioid analgesics (medications for treating intense pain).

Do not stop taking this medication abruptly, as this may cause a seizure, which could have serious consequences for both you and your baby.

Contact your doctor immediately if you become pregnant, think you may be pregnant, or plan to become pregnant while taking Gabapentina Alter.
