Prebalin is taken to treat neuropathic pain, which is pain caused by an abnormality of, or damage to, the nerves.

2. What should I know before I take Prebalin?

Warnings

Do not take Prebalin if:

  • you are allergic to pregabalin, or any of the ingredients listed at the end of this leaflet.
  • Always check the ingredients to make sure you can take this medicine.
  • 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.
    - reddish non-elevated, target-like or circular patches on the trunk, often with central blisters, skin peeling, ulcers of mouth, throat, nose, genitals and eyes.

Check with your doctor if you:

  • have any other medical conditions such as:
    - congestive heart failure,
    - hereditary problems with galactose metabolism,
    - kidney problems,
    - diabetes,
    - depression.
  • take any medicines for any other condition.
  • have a history of drug abuse.

Prebalin poses risks of abuse, misuse and dependence. Your body may become used to you taking Prebalin and this may result in physical dependence. It means that you may experience withdrawal symptoms if you stop taking Prebalin suddenly. So it is important to strictly follow the directions given by your doctor.

During treatment, you may be at risk of developing certain side effects. It is important you understand these risks and how to monitor for them. See additional information under Section 6. Are there any side effects?

Pregnancy and breastfeeding

Check with your doctor if you are pregnant or intend to become pregnant.

Prebalin is not recommended for use during pregnancy.

Pregabalin use during the first 3 months of pregnancy may cause birth defects in the unborn child that require medical treatment. In a study reviewing data from women in Nordic countries who took pregabalin in the first 3 months of pregnancy, 6 babies in every 100 had such birth defects. This compares to 4 babies in every 100 born to women not treated with pregabalin in the study.

Abnormalities of the face (orofacial clefts), the eyes, the nervous system (including the brain), kidneys and genitals have been reported.

Effective contraception must be used by women of childbearing potential.

Talk to your doctor if you are breastfeeding or intend to breastfeed.

The active ingredient in Prebalin passes into breast milk and its safety in infants is unknown. It is recommended that you do not breastfeed while taking Prebalin.

Use in children

There is not enough information to recommend the use of this medicine in children under the age of 18 years.

3. What if I am taking other medicines?

Tell your doctor or pharmacist if you are taking any other medicines, including any medicines, vitamins or supplements that you buy without a prescription from your pharmacy, supermarket or health food shop.

Prebalin and certain other medicines may influence each other (interaction). Using Prebalin with other medicines that can make you feel drowsy, such as sleeping tablets and other pain relievers (e.g. benzodiazepines and opioids), antihistamines, antidepressants, antipsychotics, cannabis, and alcohol may result in severe drowsiness, decreased awareness, breathing problems, coma and death. Your doctor will minimize the dose and duration of use; and monitor you for signs and symptoms of breathing difficulties and sedation.

You may need different amounts of your medicine, or you may need to take different medicines. Your doctor or pharmacist will advise you.

Check with your doctor or pharmacist if you are not sure about what medicines, vitamins or supplements you are taking and if these affect Prebalin.

4. How do I take Prebalin?

How much to take

  • Take Prebalin exactly as prescribed. Your doctor will tell you how much Prebalin to take.
  • Your doctor may recommend that you start with a low dose of Prebalin and slowly increase the dose to the lowest amount needed to control your epilepsy/ convulsions or neuropathic pain.
  • Follow the instructions provided and take Prebalin until your doctor tells you to stop.
  • Take Prebalin once a day, after an evening meal.
    Your medicine may not be as effective if taken on an empty stomach.

When to take Prebalin

Do not take a double dose to make up for the dose you missed.

If you take too much Prebalin

If you think that you have taken too much Prebalin, you may need urgent medical attention.

Symptoms of an overdose with Prebalin may include mood changes, feeling tired, confusion, depression, agitation, restlessness, or seizures.

You should immediately:

  • phone the Poisons Information Centre
    (by calling 13 11 26), or

You should do this even if there are no signs of discomfort or poisoning.

5. What should I know while taking Prebalin?

Things you should do

If you have nervous system or respiratory disorders, kidney problems, or you are older than 65, your doctor may adjust your dose.

If you are going to have surgery, tell you surgeon and anesthetist that you are taking Prebalin as it may affect other medicines taken during the procedure.

Call your doctor straight away if you:

  • experience any hypersensitivity reactions (such as skin redness, hives, rash, reddish non-elevated, target-like or circular patches on the trunk, often with central blisters, skin peeling, ulcers of mouth, throat, nose, genitals and eyes): Discontinue Prebalin and immediately seek medical care.
  • experience any changes in vision: Prebalin may cause blurring or other changes in eyesight.
  • have any thoughts of suicide or self-harm, any unusual changes in mood or behavior, or show signs of depression.
  • experience trouble breathing or shallow breaths.
  • become pregnant while taking Prebalin.
  • feel that Prebalin is not helping your condition.

Continue Prebalin for as long as your doctor tells you.

This medicine helps to control your condition but does not cure it. It is important to keep taking your medicine, even if you feel well.

Things you should not do

  • Do not stop taking this medicine or lower the dosage without checking with your doctor.
  • Do not let yourself run out of medicine over the weekend or on holidays.
    Stopping Prebalin suddenly may worsen your condition or increase your chance of experiencing withdrawal symptoms, such as sleeplessness, headache, nausea (feeling sick), anxiety, excessive sweating or diarrhoea (runny stools).
    If appropriate, your doctor will slowly reduce your dose before you can stop taking it completely.
  • Do not take Prebalin to treat any other symptoms unless your doctor tells you so.
  • Do not give Prebalin to anyone else, even if their symptoms seem similar to yours or they have the same condition as you.

Driving or using machines

Be careful before you drive or use any machines or tools until you know how Prebalin affects you.

Prebalin may cause dizziness and drowsiness in some people. If you experience any of these symptoms, do not drive, operate machinery or do not do anything else that could be dangerous.

Drinking alcohol

Tell your doctor if you drink alcohol.

Alcohol may interfere with Prebalin and increase side effects such as sleepiness and dizziness.

4 Clinical Particulars

4.9 Overdose

Symptoms. In overdoses up to 15 g, no unexpected adverse effects were reported.
In post-marketing experience, the most commonly reported adverse events observed when pregabalin was taken in overdose included affective disorder, somnolence, confusional state, depression, agitation and restlessness. Seizures were also reported.
Management. There is no specific antidote for pregabalin. Treatment of pregabalin overdose should be symptomatic and supportive
Consider administration of activated charcoal in the event of a potentially toxic ingestion. Activated charcoal is most effective when administered within one hour of 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.
Haemodialysis may be useful in patients with severe toxicity or those with significant renal impairment (see Section 4.2 Dose and Method of Administration, Use in renal impairment). Standard haemodialysis procedures result in significant clearance of pregabalin (approximately 50% in 4 hours). Emesis is not recommended because of the potential for CNS depression and seizures.
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. Pregabalin is not genotoxic based on results of in vitro and in vivo tests. It was not mutagenic in bacteria or in mammalian cells in vitro, not clastogenic in mammalian systems in vitro and in vivo, and did not induce unscheduled DNA synthesis in mouse or rat hepatocytes.
Carcinogenicity. Two-year carcinogenicity studies with pregabalin were conducted in rats and mice. No increased incidence of tumours was observed in rats at exposures (plasma AUC) up to 25 times the expected human exposure at the maximum recommended clinical dose of 600 mg/day. In mice, no increased incidence of tumours was found at exposures similar to the expected maximum human exposure, but an increased incidence of haemangiosarcoma was observed at exposures 6 to 33 times the expected maximum human exposure. The precise non-genotoxic mechanism of pregabalin-induced tumour formation is not fully characterised. However, available data show that platelet changes associated with the formation of this tumour in mice are not seen in rats, monkeys or humans. Although long-term data in humans are limited, these findings in mice are thought not to pose a risk to humans.
