What Deloz is and what it is used for

How does Deloz work
Deloz 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. Deloz belongs to a group of medicines called NMDAreceptor antagonists. Deloz acts on these NMDA-receptors improving the transmission of nerve
signals and the memory.
What is Deloz used for
Deloz is used for the treatment of patients with moderate to severeAlzheimer's disease
2. What you need to know before you take Deloz
Do not take Deloz
- if you are allergic to memantine hydrochloride or any of the other ingredients of this medicine
(listed in section 6).
Warnings and precautions
Talk to your doctor before taking Deloz:
- 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 Deloz
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.
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
Deloz 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.
1. Take the screw cap off the bottle:
The cap must be turned anticlockwise,
unscrewed completely and removed (figure 1).
2. Mounting the dosing pump on the bottle:
Take the dosing pump out of the plastic bag (figure 2)
and place it on top of the bottle. Carefully slide the
plastic dip tube into the bottle. Hold the dosing pump
onto the neck of the bottle and screw it clockwise until
it fits firmly (figure 3). The dosing pump is only
screwed on once, when starting the use, and it should
never be unscrewed.
3. 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 can 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 (figure 4). The dosing pump is
then ready for use.

Figure 4.

4. 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 six times in a row
(figure 5). Any solution dispensed during this step
should be discarded.
The next time the dosing pump head is pushed
downwards completely (equivalent to one pump
actuation), it dispenses the correct dose (figure 6).

Figure 5

5. Correct use of the dosing pump:
Hold the bottle in a slightly tilted 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
(figure 7, figure 8).
The dosing pump head can then be released and is
ready for the next pump actuation.

Figure 7

The dosing pump must only be used with the Deloz
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 Deloz.
