• Before taking this medicine, inform your doctor if you have ever abused or been dependent on alcohol, prescription medications, or illegal drugs; you may have a higher risk of developing dependence on Gabapentina Kern Pharma.

Dependence

Some people may develop dependence (need to continue taking the medicine) on Gabapentina Kern Pharma. They may experience withdrawal syndrome when they stop taking Gabapentina Kern Pharma (see section 3, "How to take Gabapentina Kern Pharma" and "If you stop taking Gabapentina Kern Pharma"). If you are concerned about developing dependence on Gabapentina Kern Pharma, it is essential that you consult your doctor.

If you experience any of the following signs while taking Gabapentina Kern Pharma, 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 your prescription.
• You have tried several times to stop taking the medicine or control how you take it, 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 on 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 who were being treated with antiepileptics like Gabapentina have had thoughts of self-harm or suicide. If at any time you have these thoughts, contact your doctor immediately.

Other medicines and Gabapentina Kern Pharma

Inform your doctor or pharmacist if you are using or have recently used other medicines, including those obtained without a prescription. 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.

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

No interaction is expected between this medicine and other antiepileptic medicines or oral contraceptives.

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

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

Taking Gabapentina Kern Pharma with food and drinks

This medicine can be taken with or without food.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medicine.

Do not take Gabapentina Kern Pharma during pregnancy, unless your doctor has indicated it. 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 in the case of other medicines used to treat seizures, an increased risk of fetal damage has been reported, particularly when more than one medicine is used to treat seizures at the same time. Therefore, whenever possible and only under the advice of your doctor, you should try to take only one medicine for seizures during pregnancy.

Do not stop taking this medicine abruptly, as this may cause an anticipation of the seizure, which could have serious consequences for both you and your baby.

If you take gabapentina during pregnancy, it may cause withdrawal symptoms in newborns. This risk may be higher when gabapentina is taken with opioid analgesics (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 Kern Pharma.

Gabapentina, the active ingredient of Gabapentina Kern Pharma, is excreted in breast milk. Breastfeeding is not recommended while taking Gabapentina Kern Pharma, as the effect on infants is unknown.

Driving and using machines

Gabapentina may cause symptoms such as drowsiness, dizziness, or vision changes, and may reduce your reaction ability. These effects, as well as the disease itself, may make it difficult for you to drive vehicles or operate machines. Therefore, do not drive, operate machines, or engage in other activities that require special attention until your doctor assesses your response to this medicine.

Gabapentina Kern Pharma contains castor oil

This medicine may cause stomach upset and diarrhea because it contains castor oil.
