Procedures for handling and disposal of cytotoxic medications:

1. Only trained personnel should reconstitute the solution.
2. A designated preparation area is required.
3. Staff should wear appropriate protective clothing, mask, and gloves.
4. Precautions should be taken to avoid accidental contact of the medication with the eyes. If the solution comes into contact with the skin or eyes, rinse the area immediately with plenty of water or saline solution. A cream may be used to treat temporary skin irritation. In case of eye irritation, contact an ophthalmologist.
5. Pregnant individuals should not handle this medication.

Instructions for reconstituting Treosulfano Zentiva

To avoid solubility problems during reconstitution, the following aspects should be considered:

1. The solvent, water for injectable preparations, should be heated to 25 - 30° C using a water bath.

2. Treosulfano should be carefully removed from the inner surface of the infusion vial by agitating.

This procedure is very important, as the humidification of the powder adhering to the surface results in clumping. In case of clumping, the vial should be vigorously shaken.

3. One end of the cannula is placed in the rubber stopper of the water vial, and the other end of the cannula is placed in the treosulfano vial with the opening facing downwards.

Turning the entire system allows the water to enter the lower vial while gently agitating.

Following these instructions, the reconstitution procedure should not take more than 2 minutes. See the diagram below to help with the reconstitution process:
