1. What Gabapentin Rosemont is and what it is used for

The name of your medicine is Gabapentin Rosemont 50mg/ml Oral Solution (called Gabapentin in this leaflet). Gabapentin belongs to a group of medicines used to treat epilepsy and peripheral neuropathic pain (long lasting pain caused by damage to the nerves).

For epilepsy it is used:

  • to treat various forms of epilepsy (seizures that are initially limited to certain parts of the brain, whether the seizure spreads to other parts of the brain or not). Your doctor will prescribe Gabapentin for you to help treat your epilepsy when your current treatment is not fully controlling your condition. You should take Gabapentin in addition to your current treatment unless told otherwise.
  • Gabapentin can also be used on its own to treat adults and children over 12 years of age.

For peripheral neuropathic pain (long lasting pain caused by damage to the nerves).

  • A variety of different diseases can cause peripheral (primarily occurring in the legs and/or arms) neuropathic pain, such as diabetes or shingles. Pain sensations may be described as hot, burning, throbbing, shooting, stabbing, sharp, cramping, aching, tingling, numbness, pins and needles etc.

2. What you need to know before you take Gabapentin Rosemont

Do not take this medicine if:

  • you are allergic (hypersensitive) to gabapentin or any of the other ingredients (listed in Section 6). An allergic reaction can include a rash, itching or shortness of breath.

Warnings and precautions

Talk to your doctor or pharmacist before taking Gabapentin:

  • if you suffer from kidney problems your doctor may prescribe a different dosing schedule
  • if you are on haemodialysis (to remove waste products because of kidney failure), tell your doctor if you develop muscle pain and/or weakness
  • if you develop signs such as persistent stomach pain, feeling sick and being sick contact your doctor immediately as these may be symptoms of acute pancreatitis (an inflamed pancreas)
  • if you have nervous system disorders, respiratory disorders, or you are more than 65 years old, your doctor may prescribe you a different dosing regimen.

Cases of abuse and dependence have been reported for gabapentin from the post-marketing experience. Talk to your doctor if you have a history of abuse or dependence.

A small number of people taking epilepsy medicines like Gabapentin have had thoughts of harming or killing themselves. If at any time you have these thoughts, talk to your doctor straight away.

If any of the above apply to you (or you are not sure), talk to your doctor or pharmacist before taking Gabapentin.

Important Information about potentially serious reactions

A small number of people taking Gabapentin get an allergic reaction or potentially serious skin reaction, which may develop into more serious problems if they are not treated. You need to know these symptoms to look out for while you are taking Gabapentin.

Read the description of these symptoms in section 4 of this leaflet under 'Contact your doctor immediately if you experience any of the following symptoms after taking this medicine as they can be serious'.

Muscle weakness, tenderness or pain and particularly, if at the same time, you feel unwell or have a high temperature it may be caused by an abnormal muscle breakdown which can be life-threatening and lead to kidney problems. You may also experience discoloration of your urine, and a change in blood test results (notably blood creatine phosphokinase increased). If you experience any of these signs or symptoms, please contact your doctor immediately.

Other medicines and Gabapentin

Please tell your doctor or pharmacist if you are taking or have recently taken 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.This includes medicines obtained without a prescription, including herbal medicines. This is because Gabapentin can affect the way some other medicines work. Also some other medicines can affect the way Gabapentin works.

Medicines containing opioids such as morphine

In particular tell your doctor or pharmacist if you are taking medicines containing opioids (such as morphine), used for pain. This is because morphine may increase the effect of Gabapentin. In addition, combination of Gabapentin with opioids may cause symptoms like sleepiness and/or decrease in breathing.

Antacids for indigestion

If Gabapentin and antacids containing aluminium and magnesium are taken at the same time, absorption of Gabapentin from the stomach may be reduced. It is therefore recommended that Gabapentin is taken at the earliest two hours after taking an antacid.

Gabapentin does not normally affect other medicines for epilepsy or the oral contraceptive pill.

Gabapentin may interfere with some laboratory tests, if you require a urine test tell your doctor or hospital that you are taking Gabapentin.

Gabapentin with food and drink

Gabapentin can be taken with or without food.

Pregnancy, breast-feeding and fertility

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.

Pregnancy

Gabapentin 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 no studies specifically looking at the use of gabapentin in pregnant women, but other medications used to treat seizures have reported an increased risk of harm to the developing baby, particularly when more than one seizure medication is taken at the same time. Therefore, whenever possible, you should try to take only one seizure medication during pregnancy and only under the advice of your doctor.

Contact your doctor immediately if you become pregnant, think you might be pregnant or are planning to become pregnant while taking Gabapentin. 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.

Breast-feeding

Gabapentin is passed on through human milk.

Because the effect on the baby is unknown, it is not recommended to breast-feed while using Gabapentin.

Fertility

There is no effect on fertility in animal studies.

Ask your doctor or pharmacist for advice before taking any medicine.

Driving and using machines

Gabapentin may produce dizziness, drowsiness and tiredness. You should not drive, operate complex machinery or take part in other potentially hazardous activities until you know whether this medication affects your ability to perform these activities.

Gabapentin Rosemont contains methyl and ethyl parahydroxybenzoates, potassium and sodium:

  • methyl and ethyl parahydroxybenzoates - these may cause an allergic reaction which may happen some time after starting the medicine
  • potassium (3.8mg in a 1ml dose) - if you have kidney problems or are on a low potassium diet, you need to take this into account
  • sodium (0.72mg in 1ml dose) - if you are on a low sodium diet, you need to take this into account.

3. How to take Gabapentin Rosemont
