Niacinamide and Anacaulase-bcdb

Here is the interaction we found between these two, with the evidence behind it.

Moderate

ANTICOAGULANT/ANTIPLATELET DRUGS

Why this applies to Anacaulase-bcdb

Anacaulase-bcdb falls under ANTICOAGULANT/ANTIPLATELET DRUGS — the group Niacinamide interacts with.

Theoretically, niacinamide may have additive effects when used with anticoagulant or antiplatelet drugs, especially in patients on hemodialysis.
Several cases of thrombocytopenia have been reported for hemodialysis patients treated with niacinamide 1 gram daily. Hemodialysis patients receiving niacinamide had almost a three-fold higher risk of developing thrombocytopenia when compared with those receiving placebo.

Dr. Brian Staiger explains PharmD, Clinical Pharmacist

Here's the gist for NexoBrid (anacaulase-bcdb), which is the enzyme gel doctors apply to burn wounds to remove dead tissue. It isn't a typical blood thinner you swallow, but because it can affect clotting and bleeding at the wound, it gets grouped with anticoagulant and antiplatelet drugs. The concern with niacinamide is mostly theoretical: in some hemodialysis patients, niacinamide (around 1 gram a day) was linked to a drop in platelets (thrombocytopenia), which could in turn make bleeding or bruising at a treated burn site a little more likely.

This is based on weak, anecdotal evidence and is considered unlikely for most people. Everyday vitamin B3 amounts shouldn't be an issue. Still, since NexoBrid is used on raw wounds, mention any niacinamide supplements to your care team beforehand.

Niacinamide (also called nicotinamide) is a form of vitamin B3 used in supplements and skin-care products.

It is generally well tolerated at usual doses, but high amounts should be discussed with your doctor or pharmacist.
