Warnings and precautions

Consult your doctor, pharmacist or nurse before starting to take gabapentina cinfa

There have been reports of gabapentina abuse and dependence from post-marketing experience. Talk to your doctor if you have a history of abuse or dependence.

A small number of people taking antiepileptic medicines such as gabapentina have had thoughts of self-harm or suicide. If you ever experience these thoughts, contact your doctor as soon as possible.

Dependence

Some people may develop dependence (need to continue taking the medicine) on gabapentina cinfa. They may experience withdrawal symptoms when they stop taking gabapentina cinfa (see section 3, "How to take gabapentina cinfa" and "If you interrupt treatment with gabapentina cinfa"). If you are concerned about developing dependence on gabapentina cinfa, it is essential to consult your doctor.

If you experience any of the following signs while taking gabapentina cinfa, it may indicate that you have developed dependence.

- You feel the need to take the medicine for longer than prescribed.

- You feel the need to take a higher dose than recommended.

- You are taking the medicine for reasons other than its 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.

Important information about potentially serious reactions

There have been reports of severe skin reactions associated with the use of gabapentina, including Stevens-Johnson syndrome, toxic epidermal necrolysis and drug reaction with eosinophilia and systemic symptoms (DRESS). Stop taking gabapentina and seek medical attention immediately if you notice any of the symptoms related to these severe 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 an abnormal rupture of muscle fibers that may 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.

Other medicines and gabapentina cinfa

Inform your doctor or pharmacist if you are taking, have taken recently or may need to take any other medicine. In particular, inform your doctor (or pharmacist) if you are taking or have taken recently 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 may increase the effect of gabapentina. Additionally, the combination of gabapentina with opioids may cause symptoms such as drowsiness, sedation, decreased breathing or death.

Antacids for indigestion

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

Gabapentina:

• is not expected to interact with other antiepileptic medicines or with the oral contraceptive pill.
• may interfere with some laboratory tests, so if you need a urine test, inform your doctor or the hospital about what you are taking.

Taking gabapentina cinfa 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 plan to become pregnant, consult your doctor or pharmacist before using this medicine.

Pregnancy

Do not take gabapentina during pregnancy, unless your doctor has told you to. A reliable 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, there have been reports of an increased risk of damage to the developing fetus, particularly when more than one medicine is used to treat seizures at the same time. Therefore, whenever possible, try to take only one medicine for seizures during pregnancy and only under the advice of your doctor.

Contact your doctor immediately if you become pregnant, think you may be pregnant or plan to become pregnant while taking gabapentina. Do not stop taking this medicine abruptly as this may cause an anticipation of seizures, which could have serious consequences for you and your baby.

If taken during pregnancy, gabapentina may cause withdrawal symptoms in newborns. This risk may be higher when gabapentina is taken concomitantly with opioid analgesics (pain relief medicines).

Breastfeeding

Gabapentina, the active ingredient of gabapentina cinfa, passes into breast milk. It is not recommended to breastfeed while taking gabapentina, as its effect on the baby is unknown.

Fertility

There are no effects on fertility in animal studies.

Driving and operating machinery

Gabapentina may cause symptoms such as drowsiness, dizziness or visual disturbances and may decrease your reaction time. These effects, as well as the underlying disease, may make it difficult for you to drive vehicles or operate machinery. Therefore, do not drive, operate machinery, or engage in other activities that require special attention, until your doctor assesses your response to this medicine.
