If you experience any of these signs or symptoms, please contact your doctor immediately.

Other medicines and Gabapentin Milpharm Tablets

Tell your doctor or pharmacist if you are taking, have recently taken or might take any other medicines. In particular, tell your doctor or pharmacist if you are taking or have been recently taking any medicines for convulsions, sleeping disorders, depression, anxiety, or any other neurological or psychiatric problems.

Medicines containing opioids such as morphine If you are taking any medicines containing opioids (such as morphine), please tell your doctor or pharmacist as opioids may increase the effect of Gabapentin Milpharm Tablets.

  • If you are planning to become pregnant you should discuss your treatment with your doctor as early as possible before you become pregnant.
  • You should not stop your treatment without discussing this with your doctor.

Pregnancy

Gabapentin Milpharm Tablets should not be taken during pregnancy, unless you are told otherwise by your doctor. Effective contraception must be used by women of child-bearing potential. There have been very few studies specifically looking at the use of gabapentin in pregnant women. More research is needed to better understand about the safety of use of gabapentin during pregnancy and whether it is associated with an increased risk of harm to the unborn child.

Some medicines used to treat epilepsy have reported an increased risk of harm to the developing baby, particularly when more than one seizure medication is taken at the same time. This means that where possible, your doctor should consider using one epilepsy medicine to control your epilepsy. Contact your doctor immediately if you become pregnant, think you might be pregnant or are planning to become pregnant while taking Gabapentin Milpharm Tablets. Do not suddenly discontinue taking this medicine as this may lead to a breakthrough seizure, which could have serious consequences for you and your baby.

If used during pregnancy, gabapentin may lead to withdrawal symptoms in newborn infants. This risk might be increased when gabapentin is taken together with opioid analgesics (drugs for treatment of severe pain).

Breast feeding

Gabapentin, the active substance of Gabapentin Milpharm Tablets, is passed on through human milk. Because the effect on the baby is unknown, it is not recommended to breast-feed while using Gabapentin Milpharm Tablets.

If you are pregnant or breast-feeding, think you may be pregnant or are planning to have a baby, ask your doctor or pharmacist for advice before taking this medicine.

Fertility

There is no effect on fertility in animal studies.
