1. What Ebixa is and what it is used for

Ebixa contains the active substance memantine hydrochloride. It belongs to a group of medicines known as anti-dementia medicines.

Memory loss in Alzheimer’s disease is due to a disturbance of message signals in the brain. The brain contains so-called N-methyl-D-aspartate (NMDA)-receptors that are involved in transmitting nerve signals important in learning and memory. Ebixa belongs to a group of medicines called NMDA-receptor antagonists. Ebixa acts on these NMDA-receptors improving the transmission of nerve signals and the memory.

Ebixa is used for the treatment of patients with moderate to severe Alzheimer’s disease.

2. What you need to know before you take Ebixa

Do not take Ebixa

  • if you are allergic to memantine or any of the other ingredients of this medicine (listed in section 6).

Warning and precautions

Talk to your doctor or pharmacist before taking Ebixa:

  • if you have a history of epileptic seizures
  • if you have recently experienced a myocardial infarction (heart attack), or if you are suffering from congestive heart failure or from an uncontrolled hypertension (high blood pressure).

In these situations the treatment should be carefully supervised, and the clinical benefit of Ebixa reassessed by your doctor on a regular basis.

If you suffer from renal impairment (kidney problems), your doctor should closely monitor your kidney function and if necessary adapt the memantine doses accordingly.

If you are suffering from states of renal tubulary acidosis (RTA, an excess of acid-forming substances in the blood due to renal dysfunction (poor kidney function)) or severe infections of the urinary tract (structure that carries urine), your doctor may need to adjust the dose of your medicine.

The use of medicinal products called amantadine (for the treatment of Parkinson’s disease), ketamine (a substance generally used as an anaesthetic), dextromethorphan (generally used to treat cough) and other NMDA-antagonists at the same time should be avoided.

Children and adolescents

Ebixa is not recommended for children and adolescents under the age of 18 years.

Instruction for proper use of the pump

The solution must not be poured or pumped directly into the mouth from the bottle or pump. Measure the dose onto a spoon or into a glass of water, using the pump.

Take the screw cap off the bottle:

The cap must be turned anticlockwise, unscrewed completely and removed (fig. 1).

Mounting the dosing pump on the bottle:

Take the dosing pump out of the plastic bag (fig. 2) and place it on top of the bottle. Slide the plastic dip tube carefully into the bottle. Hold the dosing pump onto the neck of the bottle and screw it clockwise until it fits firmly (fig. 3). The dosing pump is only screwed on once when starting the use, and should never be unscrewed.

How the dosing pump works:

The dosing pump head has two positions and is easy to turn:

  • anticlockwise to unlock and
  • clockwise to lock.

The dosing pump head should not be pushed down while in the locked position. The solution may only be dispensed in the unlocked position. To unlock, turn the pump head in the direction of the arrow until it cannot be turned any further (about one eighth of a turn, fig. 4). The dosing pump is then ready for use.

Preparing the dosing pump:

When used for the first time, the dosing pump does not dispense the correct amount of oral solution. Therefore, the pump must be prepared (primed) by pushing the dosing pump head down completely five times in succession (fig. 5).

The solution thus dispensed is discarded. The next time the dosing pump head is pushed downwards completely (equivalent to one pump actuation), it dispenses the correct dose (fig. 6).

Correct use of the dosing pump:

Place the bottle on a flat, horizontal surface, for example a table top, and only use it in an upright position. Hold a glass with a little water or a spoon below the nozzle. Push down the dosing pump head in a firm but calm and steady manner - not too slowly (fig. 7, fig. 8).

The dosing pump head can then be released and is ready for the next pump actuation.

The dosing pump must only be used with the Ebixa solution in the bottle provided, not for other substances or containers. If the pump does not function properly, consult your doctor or a pharmacist. Lock the dosing pump after using Ebixa.
