What is Cathflo for a PICC line?
Cathflo is alteplase, a thrombolytic drug used to “break up” a blood clot (fibrin/occlusion) in a catheter. It’s used when a PICC line becomes occluded and cannot be flushed or aspirated normally. Cathflo is given directly into the lumen of the catheter to restore patency.
When do clinicians use Cathflo on a PICC?
Cathflo is typically considered when there is evidence of a catheter occlusion, such as:
- The PICC cannot be flushed.
- Blood cannot be aspirated from the line.
- The line seems blocked despite routine troubleshooting steps.
It is not for routine use and is reserved for blocked catheters.
How is Cathflo administered into a PICC?
Clinicians follow a specific catheter-clearance protocol, which generally includes instilling alteplase into the PICC lumen, allowing it to dwell for a set period, then withdrawing/clearing the drug to re-establish blood flow. The exact dwell time and how it’s handled after dwell depend on the institution’s protocol and the product’s directions.
How long does it take to work?
After Cathflo is instilled, the goal is to re-establish function during the dwell period and with post-dwell flushing/aspiration. If the PICC does not regain patency after the first attempt, clinicians may follow escalation steps consistent with their protocol.
What are risks or side effects with Cathflo in a PICC?
Because Cathflo is a clot-busting medicine, the main risks relate to bleeding. Clinicians assess bleeding risk before using a thrombolytic, and they monitor for complications such as:
- Bleeding at the catheter site or elsewhere.
- Signs of systemic effects if drug enters circulation (risk depends on catheter position, occlusion type, and technique).
If there’s any concern for bleeding or a contraindication, the approach may change.
Is Cathflo the same as alteplase? Is it only for central lines?
Cathflo is alteplase in a thrombolytic formulation used for catheter occlusions. It is used for catheter problems involving blocked lumens, including central venous catheters, which can include PICCs, under appropriate clinical protocols.
Does Cathflo have a patent or exclusivity story?

What patients often ask: “Will Cathflo harm my PICC or affect my treatment?”
Cathflo is intended to restore PICC function so treatment can continue. It can temporarily interrupt line use while the drug dwells and the line is cleared again, but the purpose is to avoid replacing the catheter when feasible. Your care team will decide whether the line is safe to use after successful restoration of flow.
If you tell me whether you mean “what is Cathflo” or you’re dealing with an occluded PICC right now (and what symptoms you’re seeing, like can’t flush vs can’t aspirate), I can narrow the answer to the most relevant practical guidance.
