Consumer:Consumer information for this minor interaction is not currently available. Some minor drug interactions may not be clinically relevant in all patients. Minor drug interactions do not usually cause harm or require a change in therapy. However, your healthcare provider can determine if adjustments to your medications are needed.
Professional: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.
