6.6     Special precautions for disposal and other handling
Preparation of Thiotepa Riemser
Procedures for proper handling and disposal of anticancer medicinal products must be considered. All transfer procedures require strict adherence to aseptic techniques, preferably employing a vertical laminar flow safety hood.
As with other cytotoxic compounds, caution needs to be exercised in handling and preparation of Thiotepa Riemser solutions to avoid accidental contact with skin or mucous membranes. Topical reactions associated with accidental exposure to thiotepa may occur. In fact, the use of gloves is recommended in preparing the solution for infusion. If thiotepa solution accidentally contacts the skin, the skin must be immediately and thoroughly washed with soap and water. If thiotepa accidentally contacts mucous membranes, they must be flushed thoroughly with water.

Reconstitution
Thiotepa Riemser 15 mg powder for concentrate for solution for infusion Thiotepa Riemser must be reconstituted with 1.5 ml of sterile water for injections.
Using a syringe fitted with a needle, aseptically withdraw 1.5 ml of sterile water for injections.

Thiotepa Riemser 100 mg powder for concentrate for solution for infusion Thiotepa Riemser must be reconstituted with 10 mL of sterile water for injections.
Using a syringe fitted with a needle, aseptically withdraw 10 mL of sterile water for injections.

Inject the content of the syringe into the vial through the rubber stopper.
Remove the syringe and the needle and mix manually by repeated inversions.
Only colourless solutions, without any particulate matter, must be used. Reconstituted solutions may occasionally show opalescence; such solutions can still be administered.

Further dilution in the infusion bag
The reconstituted solution is hypotonic and must be further diluted prior to administration with 500 ml sodium chloride 9 mg/ml (0.9%) solution for injection (1000 ml if the dose is higher than 500 mg) or with an appropriate volume of sodium chloride 9 mg/ml (0.9%) in order to obtain a final Thiotepa Riemser concentration between 0.5 and 1 mg/ml.

Administration
Thiotepa Riemser infusion solution should be inspected visually for particulate matter prior to administration. Solutions containing a precipitate should be discarded.
Prior to and following each infusion, the indwelling catheter line should be flushed with approximately 5 ml sodium chloride 9 mg/ml (0.9%) solution for injection.
The infusion solution must be administered to patients using an infusion set equipped with a 0.2 µm in-line filter. Filtering does not alter solution potency.

Disposal
Thiotepa Riemser is for single use only.
Any unused product or waste material should be disposed of in accordance with local requirements.
