Here's what I got from drugs.com at the drug interaction checker:

Salicylates may cause an elevation in serum levels of nicotinic acid. The mechanism is not completely understood. However, salicylates also significantly decrease the serum levels of nicotinuric acid--a metabolite--and some experts hypothesize that salicylic acid causes a concentration-dependent decrease in the total clearance of nicotinic acid. Such a decrease would result in the saturation of the nicotinuric acid conjugation pathway. Data are available for aspirin only. No special precautions appear to be necessary.

ETA: I seem to be having difficulties in completing posts. LOL! The flushing I wanted to avoid at *all* costs. I have itching to begin with. I take Zyrtec for that. The flushing is what my feet often feel like, one of the worse symptoms I experience. No way do I even want to tempt an increase in symptoms of any kind...anywhere.
