Instructions for the correct use of the dosifier

The solution must not be poured or dispensed directly into the mouth from the bottle or dosifier. Measure the dose in a spoon or in a glass of water using the dosifier.

Removing the rosca cap from the bottle:

The cap must be turned in the opposite direction to the clock, completely unscrewed and removed (fig. 1).

Mounting the dosifier on the bottle:

Remove the dosifier from the plastic bag (fig. 2) and place it on top of the bottle. Carefully insert the plastic tube into the bottle. Keep the dosifier on the bottle neck and turn it clockwise until it is securely attached (fig. 3). The dosifier should only be screwed on once when starting use and should never be unscrewed.

How the dosifier works:

The dosifier head has two positions and turns easily:

- in the opposite direction to the clock to open and

- in the direction of the clock to close.

The dosifier head should not be pressed down while it is in the closed position. The solution can only be dispensed in the open position. To open, turn the dosifier head in the direction indicated by the arrow until it cannot be turned any further (about one-eighth of a turn, fig. 4). The dosifier is then ready for use.

Preparing the dosifier:

When used for the first time, the dosifier does not dispense the correct amount of oral solution. Therefore, it must be prepared (primed) by pressing the dosifier head down completely five times in a row (fig. 5).

The solution dispensed in this way must be discarded. The next time the dosifier head is pressed down completely (equivalent to one press), it already dispenses the correct dose (fig. 6).

Correct use of the dosifier:

Place the bottle on a flat, horizontal surface, such as a table, and use it only in a vertical position.Place a glass with a little water or a spoon under the nozzle. Press the dosifier head down firmly, but calmly, steadily and not too slowly (fig. 7 and fig. 8).

Subsequently, the dosifier head can be released and will be ready for the next press.

The dosifier should only be used with the Memantina Viatris solution in the bottle provided, not for other products or containers. If the dosifier does not work correctly, consult your doctor or pharmacist. Close the dosifier after using Memantina Viatris.
