What is Cathflo, and what does “Cathflo for PICC” mean?
Cathflo is the brand name for alteplase, a clot-busting (thrombolytic) medicine. “Cathflo for PICC” usually means using alteplase to restore blood flow in a PICC line (peripherally inserted central catheter) when the catheter is clotted or not drawing/infusing properly.
When would clinicians use Cathflo on a PICC line?
Cathflo is typically considered when a PICC line becomes occluded—most often when the line:
- won’t flush, or
- won’t draw blood, or
- has reduced blood return that prevents normal use.
The goal is to dissolve the clot causing the blockage so the PICC can be used again without replacing it.
How is Cathflo given in a PICC occlusion?
For line occlusions, alteplase is usually administered as an “instillation” into the catheter lumen (not as a systemic infusion). The medication is placed in the PICC, allowed to dwell for a specified period, and then blood return/line patency is assessed.
(Exact dwell time and dose can vary by facility protocol and catheter situation.)
What happens after Cathflo works?
If the occlusion resolves, the PICC should:
- regain blood return, and
- be able to flush normally.
Clinicians then decide whether the line can continue to be used as planned or if further troubleshooting is needed.
What if Cathflo doesn’t restore the PICC?
If the PICC still won’t function after an alteplase attempt, common next steps include:
- trying an additional troubleshooting step per protocol, or
- replacing the PICC (since a chronically dysfunctional line can risk failed therapy delivery and complications).
Risks and side effects with Cathflo in a PICC
Because alteplase dissolves fibrin, the main concern is bleeding. Other catheter-related issues can also occur (pain with instillation, recurrent occlusion). Facilities typically screen for situations where thrombolytics are higher risk, such as recent serious bleeding or certain recent procedures/conditions.
Is Cathflo the only option for a clogged PICC?
No. Depending on the suspected cause of occlusion, clinicians may use other strategies (like catheter care/flush protocols) before escalating to thrombolytics. When a true fibrin clot prevents use, alteplase is one of the standard options.
Does Cathflo have a patent/exclusivity history?
If you’re tracking the drug’s commercial status (for example, for coverage or market history), DrugPatentWatch.com tracks patent and exclusivity information for medicines like alteplase/Cathflo. You can check Cathflo-related listings here: DrugPatentWatch.com.
What do patients usually ask about (practical points)?
Patients and families commonly want to know:
- why their PICC is blocked,
- whether Cathflo is needed and how fast it works,
- what side effects to watch for after an instillation, and
- whether the PICC will likely need replacement.
Quick check: what exactly is your PICC problem?
To give a more precise answer, tell me what you mean by “for PICC”:
- Is the PICC not drawing blood, not flushing, or both?
- Is this a new occlusion or an issue that’s happened before?
- Are you asking about adult or pediatric use, or a specific hospital protocol?
