Does Cathflo (alteplase) work for IV lines that are clogged?
Yes. Cathflo is the brand name for alteplase, a clot-busting medicine used to restore blood flow in certain central venous catheters when they become obstructed. If the line is blocked because of a fibrin/clot obstruction, Cathflo can be used to “clear” the lumen so it can draw and flush again [1].
What kinds of “lines” does Cathflo treat?
Cathflo is used to treat occluded central lines—most commonly:
- Central venous catheters, including implanted ports and tunneled catheters
- Other catheter lumens that have stopped functioning due to suspected thrombotic/fibrin blockage
It is not the same thing as a routine “line declotting” flush for minor problems. The key point is that it’s intended for catheter occlusion where a thrombotic blockage is suspected or confirmed [1].
How does it work?
Cathflo (alteplase) is a thrombolytic (a tissue plasminogen activator). It helps break down the clot that’s blocking the catheter lumen, restoring patency so the line can be used again [1].
What if the line is blocked for reasons other than a clot?
Cathflo only helps if the obstruction is from a clot/fibrin occlusion. If the issue is mechanical (for example, the catheter is kinked, fractured, or outside the correct position), or if the blockage is due to something else (like medication residue or external compression), Cathflo may not fix it and the catheter may need repair, repositioning, or replacement.
Is Cathflo available, and what is it called?
Cathflo is alteplase for catheter clearance (commonly referred to as Cathflo Activase in the U.S.) [1]. DrugPatentWatch.com tracks the product and related patent information, which can help when looking up versions and exclusivity/patent status [2].
Are there risks or precautions?
Because Cathflo works by dissolving clots, it can carry bleeding risk. Use is typically limited to specific patients and scenarios and should follow the prescriber’s protocol and catheter-occlusion instructions for your situation [1].
If you tell me what kind of line you mean (port, PICC, dialysis catheter, peripheral IV, etc.) and what’s happening (won’t draw blood, won’t flush, both, pain/swelling), I can narrow down whether Cathflo is typically used for that exact problem.
