Consumer medicine information (CMI) leaflet

Please read this leaflet carefully before you start using Gabapentin Generichealth.

What is in this leaflet

This leaflet answers some common questions about Gabapentin generichealth. It does not contain all the available information. It does not take the place of talking to your doctor or pharmacist. All medicines have risks and benefits. Your doctor has weighed the risks of you taking Gabapentin generichealth against the benefits it is expected to have for you.

If you have any concerns about taking this medicine, ask your doctor or pharmacist.

Keep this leaflet with the medicine. You may need to read it again.

What Gabapentin generichealth is used for

What Gabapentin generichealth does

Gabapentin generichealth is used to control epilepsy.

Epilepsy is a condition where you have repeated seizures (fits). There are many different types of seizures, ranging from mild to severe.

Gabapentin generichealth is also used to treat neuropathic pain, a type of pain caused by damage to the nerves. This medicine belongs to a group of medicines called anticonvulsants.

How Gabapentin generichealth works

This medicine is thought to work by controlling brain chemicals which send signals to nerves to help control seizures or neuropathic pain.

Gabapentin generichealth also has pain relieving effects.

Your doctor may have prescribed Gabapentin generichealth in addition to other medicines that you may be taking. This may be necessary if your current treatment is no longer working as well.

Your doctor may have prescribed Gabapentin generichealth for another reason.

Gabapentin generichealth may lead to dependence on this medicine.

Ask your doctor if you have any questions about why Gabapentin generichealth has been prescribed for you.

This medicine is available only with a doctor's prescription.

Use in children

There is not enough information to recommend the use of this medicine in children:

  • under the age of 3 years to control epilepsy, or
  • under the age of 18 years to treat neuropathic pain.

Before you take Gabapentin generichealth

When you must not take it

Do not take Gabapentin generichealth if you have an allergy to:

  • any medicine containing gabapentin, the active ingredient in Gabapentin generichealth;
  • any of the ingredients listed at the end of this leaflet.

Some of the symptoms of an allergic reaction may include:

  • shortness of breath;
  • wheezing or difficulty breathing;
  • swelling of the face, lips, tongue or other parts of the body;
  • rash, itching or hives on the skin.

Do not take Gabapentin generichealth after the expiry date printed on the pack or if the packaging is torn or shows signs of tampering. If it has expired or is damaged, return it to your pharmacist for disposal.

If you are not sure whether you should start taking Gabapentin generichealth, talk to your doctor or pharmacist.

Before you start to take it

Tell your doctor or pharmacist if you have allergies to:

  • any other medicines, especially barbiturates or any other anticonvulsant medicines;
  • any other substances, such as foods, preservatives or dyes.

Tell your doctor if you have or have had any of the following medical conditions:

  • kidney problems;
  • mixed seizure disorders that include absence seizures.

Tell your doctor if you are pregnant or plan to become pregnant. Gabapentin generichealth may affect your developing baby if you take it during pregnancy. However, it is very important to control your fits while you are pregnant. If it is necessary for you to take Gabapentin generichealth, your doctor can help you decide whether or not to take it during pregnancy.

Tell your doctor if you are breastfeeding or plan to breast-feed. Gabapentin generichealth passes into breast milk. The effect on your breast-fed baby is unknown.

If you do breast-feed, watch your baby carefully. If your baby develops a skin rash, becomes sleepy or has unusual symptoms, don't breast-feed again until you speak to your doctor. Your doctor can discuss the risks and benefits of breast-feeding with you.

If you have not told your doctor or pharmacist about any of the above, tell them before you start taking Gabapentin generichealth.

Taking other medicines

Tell your doctor or pharmacist if you are taking any other medicines, including:

  • all prescription medicines;
  • all medicines, vitamins, herbal supplements or natural therapies you buy without a prescription from a pharmacy, supermarket, naturopath or health food shop.

Some medicines may be affected by Gabapentin generichealth or may affect how well it works. You may need different amounts of your medicines, or you may need to take different medicines. Your doctor or pharmacist will advise you accordingly.

Tell your doctor or pharmacist if you are taking any of the following:

  • cimetidine, a medicine used to treat stomach or duodenal ulcers;
  • antacids, medicines used to treat heartburn or reflux;
  • opioids, medicines used to treat severe pain, eg. morphine.

Your doctor and pharmacist have more information on medicines to be careful with or avoid while taking gabapentin.

How to take Gabapentin generichealth

Follow all directions given to you by your doctor or pharmacist carefully. They may differ from the information contained in this leaflet.

If you do not understand the instructions on the pack, ask your doctor or pharmacist for help.

How much to take

Your doctor will tell you how many capsules you need to take each day. This may depend on your age, your condition and whether or not you are taking any other medicines.

Your doctor may recommend that you start with a low dose of Gabapentin generichealth and slowly increase the dose to the lowest amount needed to control your epilepsy/ convulsions or neuropathic pain.

How to take it

Swallow Gabapentin generichealth capsules whole with a full glass of water.

When to take it

Take your Gabapentin generichealth capsules at about the same time each day. Taking your Gabapentin generichealth capsules at the same time each day will have the best effect. It will also help you remember when to take the capsules.

If you are taking Gabapentin generichealth three times a day, do not allow more than 12 hours between doses.

It does not matter if you take Gabapentin generichealth before or after food.

How long to take it

Continue taking your medicine for as long as your doctor tells you to.

Gabapentin generichealth helps control your condition, but does not cure it. Therefore you must take your medicine every day, even if you feel well.

Do not stop taking Gabapentin generichealth, or lower the dose, without checking with your doctor. Do not let yourself run out of medicine over the weekend or holidays. Stopping Gabapentin generichealth suddenly may cause unwanted side effects or make your condition worse. Your doctor will slowly reduce your dose before you can stop taking it completely.

If you forget to take it

If it is almost time for your next dose (within 4 hours), skip the dose you missed and take your next dose when you are meant to.

Otherwise, take it as soon as you remember, and then go back to taking your Gabapentin generichealth as you would normally.

Do not take a double dose to make up for the dose that you missed. This may increase the chance of you getting an unwanted side effect.

If you are not sure what to do, ask your doctor or pharmacist. If you have trouble remembering to take your Gabapentin generichealth, ask your pharmacist for help.

If you take too much (overdose)

Immediately telephone your doctor or Poisons Information Centre (telephone Australia 13 11 26) for advice, or go to the Accident and Emergency area at the nearest hospital, if you think that you or anyone else may have taken too much gabapentin.

Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.

Symptoms of an overdose may include you falling unconscious, feeling drowsy, weak, unsteady when walking, having double vision, slurred speech or diarrhoea.

While you are taking Gabapentin generichealth

Things you must do

If you are about to be started on any new medicine, remind your doctor and pharmacist that you are taking Gabapentin generichealth.

Tell any other doctors, dentists, and pharmacists who treat you that you are taking Gabapentin generichealth.

If you are going to have surgery or emergency treatment, tell the surgeon or anaesthetist that you are taking Gabapentin generichealth.

Tell your doctor immediately if you have any thoughts of suicide or self-harm, any unusual changes in mood or behaviour, or show signs of depression. Some people being treated with antiepileptics, such as gabapentin, have had thoughts of harming or killing themselves.

Patients and caregivers should be alert and monitor for signs and symptoms of suicide, these include:

  • thoughts or talk of death or suicide;
  • thoughts or talk of self-harm or harm to others;
  • any recent attempts of self-harm;
  • new or an increase in aggressive behaviour, irritability or agitation;
  • new onset of or worsening of depression.

Mention of suicide or violence must be taken seriously.

If you or someone you know is demonstrating these warning signs and symptoms of suicide while taking Gabapentin generichealth, contact your doctor or a mental health professional right away.

Tell your doctor if you feel Gabapentin generichealth is not helping your condition. Your doctor may need to change your medicine

Tell your doctor if, for any reason, you have not taken Gabapentin generichealth exactly as prescribed. Otherwise, your doctor may change your treatment unnecessarily.

If you become pregnant while taking Gabapentin generichealth, tell your doctor immediately.

If you need to have any medical tests while you are taking Gabapentin generichealth, tell your doctor. It may interfere with the results of some tests.

If you are going to have any surgery or procedure, including dental surgery, tell your surgeon, doctor or dentist that you are taking this medicine.

Keep all of your doctor's appointments so that your progress can be checked. Your doctor will check your progress and may want to take some tests from time to time. This helps to prevent unwanted side effects.

Things you must not do

Do not take Gabapentin generichealth to treat any other complaints unless your doctor tells you to.

Do not give Gabapentin generichealth to anyone else, even if their symptoms seem similar to yours or they have the same condition as you.

Do not stop taking Gabapentin generichealth or lower the dose without checking with your doctor. Stopping Gabapentin generichealth suddenly, if you have epilepsy, may cause unwanted side effects or make your condition worse. Your doctor will slowly reduce your dose before you can stop taking it completely.

Things to be careful of

Be careful driving or operating machinery until you know how Gabapentin generichealth affects you. As with other anticonvulsant medicines, Gabapentin generichealth may cause drowsiness, dizziness, light-headedness or sleepiness in some people. Make sure you know how you react to Gabapentin generichealth before you drive a car, operate machinery, or do anything else that could be dangerous if you are dizzy or light-headed. If this occurs do not drive.

Children should not ride a bike, climb trees or do anything else that could be dangerous if they are feeling drowsy or sleepy.

Be careful when drinking alcohol while you are taking Gabapentin generichealth. Combining Gabapentin generichealth and alcohol can make you more sleepy, dizzy or light-headed. Your doctor may suggest you avoid alcohol while you are being treated with gabapentin.

Side effects

Tell your doctor or pharmacist as soon as possible if you do not feel well while you are taking Gabapentin generichealth.

All medicines can have side effects. Sometimes these are serious, but most of the time these are not. You may need medical attention if you get some side effects.

It can be difficult to tell whether side effects are the result of taking Gabapentin generichealth; of your condition; or side effects of other medicines you may be taking, for this reason it is important to tell your doctor of any change in your condition.

If you are over 65 years of age you may have an increased chance of getting side effects.

Ask your doctor or pharmacist to answer any questions you may have.

If you get any side effects, do not stop taking Gabapentin generichealth without first talking to your doctor or pharmacist.

Boxed Warnings

Abuse potential or dependence. Gabapentin is a potential drug of abuse and dependence. Gabapentin poses risks of abuse and dependence which can lead to overdose and death especially when used concomitantly with opioids and other CNS depressants. Assess the patient's risk of abuse or dependence before prescribing and monitor the patient regularly during treatment, particularly amongst patients with current or past abuse or dependence of opioids and/or benzodiazepines (see Section 4.4 Special Warnings and Precautions for Use).

4 Clinical Particulars

4.9 Overdose

Signs and symptoms. Symptoms of an overdose included somnolence, ataxia, dizziness, double vision, nystagmus, slurred speech, drowsiness, loss of consciousness, lethargy, mild hypotension and gastrointestinal symptoms including diarrhoea. Gabapentin overdose alone has not been reported to produce significant cardiotoxicity.
Overdoses as high as 108 g have been reported with full recovery following symptomatic therapy. Reduced absorption of gabapentin at higher doses may limit drug absorption at the time of overdosing and, hence, minimise toxicity from overdoses.
Treatment of overdosage. There is no specific antidote for gabapentin; treatment is symptomatic. The patient should be monitored closely and given supportive care where necessary to maintain vital functions. Overdoses may involve other concurrent medications and should be treated accordingly.
Activated charcoal may reduce absorption of the drug if given within one hour after ingestion. In patients who are not fully conscious or have impaired gag reflex, consideration should be given to administering activated charcoal via nasogastric tube once the airway is protected.
Gabapentin can be removed by haemodialysis. Although haemodialysis has not been performed in the few overdose cases reported, it may be indicated by the patient's clinical state or in patients with significant renal impairment.
Ipecac-induced emesis is not recommended because of the potential for CNS depression.
For information on the management of overdose, contact the Poisons Information Centre on 13 11 26 (Australia).

5 Pharmacological Properties

5.3 Preclinical Safety Data

Genotoxicity. There is no evidence that gabapentin has genotoxic potential. It was not mutagenic in vitro in standard assays using bacterial or mammalian cells. Gabapentin did not induce structural chromosome aberrations in mammalian cells in vitro or in vivo, and did not induce micronucleus formation in the bone marrow of hamsters.
Carcinogenicity. Gabapentin was given in the diet to mice at 200, 600, and 2000 mg/kg/day and to rats at 250, 1000 and 2000 mg/kg/day for 2 years. A statistically significant increase in the incidence of pancreatic acinar cell adenoma and carcinoma was found only in male rats at the highest dose. Peak plasma gabapentin concentrations and areas under the concentration time curve in rats at 2000 mg/kg/day were 14 times higher than plasma concentrations in humans given the recommended maximum tolerated dose of 2400 mg/day. The pancreatic acinar cell tumours in male rats were low grade malignancies, which did not metastasise or invade surrounding tissue, and were similar to those seen in concurrent controls. The relevance of these pancreatic acinar cell tumours in male rats to carcinogenic risk in human is unclear.
