Instructions for use
Hydrozid is as easy as 1-2-3
Step 1 Step 1 Remove Hydrozid from the pack. Hydrozid is locked (the disk extension is placed to the left). This feature prevents unintended spraying both while carrying Hydrozid or between treatments.
 
 
Step 2 Step 2 Move the disk extension to the right to open the spray head. Hydrozid is applied to a lesion directly from the canister. No anaesthesia prior to treatment is required.
 
 
Step 3 Step 3 Hydrozid is now ready to use. To avoid damaging the surrounding tissue use one of the application templates provided in the Hydrozid pack. Select the hole matching the size of the individual lesion. Freeze the lesion by applying Hydrozid from a distance of 2 to 3 cm followed by a complete thaw. After a short interval, repeat the freeze-thaw cycle. Several repeated freeze-thaw cycles are recommended as in a single treatment. The total duration of application to a lesion must be kept within the recommended maximum total (see panel). For large lesions, it is recommended to apply the jet in circle movements from the center of the lesion to the external in a circle within the given area.
