or pharmacist if you are not sure.

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. 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 (figure 3). The dosing pump is only screwed on once when starting the
use, and should never be unscrewed.
Figure 2

Figure 3

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 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 (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 succession (figure 5).
Figure 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 (figure 6).
Figure 6

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).
Figure 7

Figure 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 Memantine oral 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 Memantine oral solution.
