Summary
Non-acetylated salicylates may slightly blunt the blood pressure lowering of antihypertensives through reduced vasodilatory prostaglandins and sodium retention. The effect is generally small and is less pronounced than with conventional NSAIDs.
What this interaction means in plain words
Doxazosin and Salicylates have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Why it happens
Inhibition of prostaglandin synthesis may cause sodium and fluid retention and offset vasodilation.
What to do
No routine change is needed; check blood pressure if salicylates are used regularly at anti-inflammatory doses.

- Is there anything I should notice while taking both?
