Preparation and handling of hazardous drugs for special administration
HAZARDOUS
GUIDE
NOTE: Please consult Drug Information or a pharmacist for specific instructions before proceeding to reconstitute any hazardous drugs, including cytotoxics!
[Off-label] Note: administer the dispersion immediately after preparing.
1. Stop enteral feed. Flush the enteral feeding tube with the recommended volume of water. 2. Gloves and mask should be worn in case of accidental spillage and exposure. 3. Open the capsule and carefully pour the powder contents into a disposable medicine cup. 4. Add 15mL of Water for Injection, and stir to disperse the powder. 5. Draw the liquid into an appropriate syringe (eg. 20mL Terumo syringe) and administer via the feeding tube. 6. Add another 15mL Water for Injection to the medicine pot. Stir to ensure that any powder remaining in the pot is mixed with water. 7. Draw up this dispersion and flush down tube. This will ensure that the whole dose is given. 8. Finally, flush with the recommended volume of water.
[Off-label] Note: administer the dispersion immediately after preparing.
1. Stop enteral feed. Flush the enteral feeding tube with the recommended volume of water. 2. Gloves and mask should be worn in case of accidental spillage and exposure. 3. Place the tablet in the barrel of an appropriate size and type of syringe (eg. 20mL Terumo syringe). 4. Draw 10mL of Water for Injection into the syringe and allow the tablet to dissolve, shaking if necessary. 5. Flush the medication dose down the feeding tube. 6. Draw another 10mL of Water for Injection into syringe and flush this via feeding tube (this will rinse the syringe and ensure that total dose is administered). 7. Finally, flush with the recommended volume of water.

Preparation of oral suspension dose for NGT administration
Stop enteral feed. Flush the enteral feeding tube with the recommended volume of water.
Gloves and mask should be worn in case of accidental spillage and exposure.
Open the capsules and carefully transfer contents into a clean cup. Discard empty capsules.
Add approximately 40mL of water to the plastic cup.
Mix/stir the capsule contents and water for 3 minutes. NOTE: the prepared mixture may have visible undissolved particulates and are acceptable for administration. This is because capsule contents may not dissolve completely.
Using a Terumo syringe, draw up entire contents of the plastic cup and administer immediately through the NGT.
If any portion of the capsule contents are left in the cup/syringe, add 10 mL of water to the cup/syringe, mix, and administer again through the NGT.
Repeat steps 6 to 7 as needed until no capsule contents are left in the cup or syringe.
Flush the NGT with 5 mL of water twice (10 mL total) after administration of the mixture.

Open the capsule and carefully pour the powder contents into an appropriate-sized Terumo syringe (e.g. 20mL). 4. Add 15mL of Water for Injection into the syringe, and shake gently to disperse the powder. 5. Administer the mixture in the syringe via the feeding tube. 6. Add another 15mL Water for Injection to the Terumo syringe and shake gently to ensure that any powder remaining in the syringe is mixed with water. 7. Flush the water in the syringe down the tube.

Rationale For Closed System Administration of Cytotoxics
-
This closed system is preferred for cytotoxics for which no liquid formulation is available, so as to avoid environmental contamination and exposure of carer to the hazardous medicine. Not recommended to be crushed due to risk of powder inhalation
-
Exposure to such substances is dangerous; therefore, contact with the skin and inhalation of dust should be avoided and protective equipment devices (gloves and mask) must be used
-
Women with pregnancy potential should avoid handling crushed or broken tablets. To wear gloves and mask when handling
-
Suitable protective clothing should be worn. Contaminated equipment should be disposed of as cytotoxic waste
