Consumer Medicine Information

What is in this leaflet

This leaflet answers some common questions about Gamine XR modified release capsules. 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 this medicine against the benefits this medicine is expected to have for you.

Ask your doctor or pharmacist if you have any concerns about taking Gamine XR.

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

What Gamine XR is used for

Gamine XR is used to treat mild to moderately severe dementia of the Alzheimer’s type.

The symptoms of Alzheimer’s disease include confusion, memory loss or other changes in behaviour. As the disease progresses, patients find it more and more difficult to carry out their normal daily activities.

The symptoms of Alzheimer’s disease are thought to be due to lack of acetylcholine, a substance which transmits messages between brain cells. Gamine XR increases the amount of this substance to help improve or stabilise the symptoms and therefore slow the progress of Alzheimer’s disease.

Your doctor may have prescribed this medicine for another reason.

Ask your doctor if you have any questions about why this medicine has been prescribed for you.

Before you take it

When you must not take it

Do not take Gamine XR if you have:

  • an allergy to Gamine XR or any of the ingredients. See Product Description at the end of this leaflet for a list of ingredients
  • severe liver and/or kidney disease.

Do not take this medicine if the packaging is torn or shows signs of tampering.

Do not use it beyond the expiry date (month and year) printed on the pack.

Before you take it

You must tell your doctor if you are:

  • pregnant, or planning to become pregnant
  • breastfeeding, or planning to breastfeed
  • planning to undergo surgery which will require anesthesia

You must also tell your doctor if you have, or have had any of the following health problems:

  • liver and/or kidney disease
  • heart problems
  • stomach ulcers
  • brain disorders, such as Parkinson’s disease, fits
  • problems controlling movements of the body or limbs (extrapyramidal disorder)
  • breathing disorders, such as asthma, pneumonia
  • recent gut or bladder surgery
  • difficulties in passing urine
  • attacks of sudden abdominal pain

If you have not told your doctor or pharmacist about any of the above, tell them before you start taking or are given Gamine XR.

Your doctor will advise you whether or not to take Gamine XR or if you need to adjust the dose or alter your treatment.

Since there may be other related conditions that this medicine is not intended to treat, you should verify with your doctor that you are taking it for the treatment of mild to moderate Alzheimer’s disease.

Initial results from clinical trials in patients with mild cognitive impairment of various causes have shown a slightly higher mortality rate (higher death rate) in those taking Gamine XR than those taking a placebo (a pill without an active ingredient which is commonly used in clinical trials as a reference for comparison). The reason for this difference is currently not known and may just be due to chance. There is no evidence of increased risk of death for those with mild to moderately severe Alzheimer’s disease taking Gamine XR.

Taking other medicines

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

In particular, tell your doctor or pharmacist if you are taking any other the following:

  • anticholinergic medicines (used to prevent travel sickness, relieve stomach cramps, spasms or diarrhea)
  • cholinergic medicines (e.g. bethanecol and certain medicines used during surgery)
  • medicines used to treat Parkinson’s disease
  • medicines for certain heart problems (such as digoxin, quinidine) or to help lower blood pressure (such as class of medicine called beta blockers)
  • medicines used for breathing problems
  • certain medicines used to treat fungal infections (such as ketoconazole) or bacterial infections (such as erythromycin)
  • certain medicines used to relieve pain, swelling and other symptoms of inflammation, including arthritis
  • certain medicines used to treat depression (such as paroxetine fluoxetine, fluvoxamine).

These medicines may be affected by Gamine XR or may affect how well it works. Your doctor or pharmacist can tell you what to do if you take any of these medicines.

Effects on driving and operating machinery

  • Alzheimer’s disease may reduce your ability to drive or operate machinery.
  • Gamine XR may cause dizziness or drowsiness in some people, especially during initial treatment.
  • Discuss with your doctor whether it is safe for you to drive or operate machinery.

How to take it

Gamine XR modified release capsules should be taken once a day, preferably with food. Be sure to drink plenty of liquids during your treatments to keep yourself hydrated. The capsule must be swallowed whole. The contents should not be crushed or sprinkled on food.

The dose of Gamine XR is gradually increased to the most suitable dose. The necessary dosage steps should be determined by your doctor to suit your needs.

The following scheme is an example of how your doctor may increase your dose:

  • Start with 8 mg a day
  • After 4 weeks of treatment, raise the dose to 16 mg a day
  • After at least another 4 weeks of treatment, raise the dose to 24 mg a day.

For long-term treatment, up to 24 mg a day is usually suitable but your doctor will determine the dose that is best for you.

If treatment is discontinued for more than several days, tell your doctor. Your doctor will need to restart your treatment at the lowest dose. This will minimize the chance of experiencing side effects.

Gamine XR is not recommended for children.

If you do not understand the instructions provided with this medicine, ask your doctor or pharmacist for help.

If you forget to take it

  • If it is almost time for your next dose, 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 it as you normally would.
  • Do not take a double dose to make up for the dose you missed.

If you have missed more than one dose, or are not sure what to do, check with your doctor or pharmacist.

If you have trouble remembering when to take your medicine, ask your pharmacist for some hints.

If you take too much (overdose)

Immediately telephone your doctor or Poisons Information Centre for advice, or go to Accident and Emergency at your nearest hospital. Do this even if there are no signs of discomfort or poisoning. You may need urgent medical attention.
