What is Cathflo used for with a PICC line?
Cathflo (alteplase) is a thrombolytic medicine used to restore blood flow when a PICC line (peripherally inserted central catheter) becomes occluded (clotted) or won’t draw/infuse properly. It works by breaking down fibrin clots in the catheter.
Is Cathflo a “replacement” for fixing PICC problems?
No. Cathflo is used after a PICC problem is identified as a catheter occlusion. Typical steps before/alongside catheter-directed therapy can include checking for mechanical causes (like kinks or incorrect position) and following local line-care protocols. If the issue is truly an occluded lumen, alteplase is the standard way to try to restore patency.
How is Cathflo given for a PICC occlusion?
Cathflo is instilled directly into the blocked catheter lumen. The exact dwell time and volume depend on the catheter protocol and the specific order set used by the facility, but the goal is to let alteplase dwell long enough to dissolve the clot, then resume normal line use after the medication is cleared and patency is confirmed.
How long does it take to work?
Time to effect depends on how complete the blockage is and how long the occlusion has been present. In practice, clinicians evaluate catheter function shortly after the dwell period ends; if blood return and infusion ability return, the PICC can usually be used as ordered.
What side effects or risks are associated with Cathflo in PICCs?
Because Cathflo dissolves clots, the main concern is bleeding or clot-related complications in patients who already have bleeding risk. Other effects are generally related to the catheter procedure and the patient’s baseline condition. Clinicians weigh risks based on recent surgery, active bleeding, platelet/anticoagulation status, and other factors in the patient’s chart.
Is Cathflo the only option for a PICC that won’t draw?
Not always. Some PICC problems are not true clots (for example, line position, kinks, or external compression). For confirmed occlusion, alteplase is the targeted pharmacologic option commonly used. Facilities may also use different approaches depending on whether the lumen is partially occluded, whether occlusion is suspected to be fibrin, or whether there are contraindications to thrombolytics.

Quick clarification so I can answer more precisely
When you say “Cathflo picc,” do you mean:
1) what it’s used for (clogged PICC),
2) dosing/dwell time and how to administer, or
3) side effects/when it’s contraindicated?
