DOSAGE AND ADMINISTRATION
Instructions for Administration
Instillation of Solution into the Catheter Inspect the product prior to administration for foreign matter and discoloration. Withdraw 2 mL (2 mg) of solution from the reconstituted vial. Instill the appropriate dose of Cathflo Activase (see DOSAGE AND ADMINISTRATION) into the occluded catheter. After 30 minutes of dwell time, assess catheter function by attempting to aspirate blood. If the catheter is functional, go to Step 7. If the catheter is not functional, go to Step 5. After 120 minutes of dwell time, assess catheter function by attempting to aspirate blood and catheter contents. If the catheter is functional, go to Step 7. If the catheter is not functional, go to Step 6. If catheter function is not restored after one dose of Cathflo Activase, a second dose of equal amount may be instilled. Repeat the procedure beginning with Step 1 under Preparation of Solution. If catheter function has been restored, aspirate 4-5 mL of blood in patients >/=10 kg or 3 mL in patients <10 kg to remove Cathflo Activase and residual clot, and gently irrigate the catheter with 0.9% Sodium Chloride Injection, USP. Any unused solution should be discarded.
