Summary
Antacids that alkalinize urine increase salicylate excretion, but aluminum hydroxide has little urinary alkalinizing effect at usual doses. Salicylate levels may shift slightly in patients on high doses.
What this interaction means in plain words
Aluminum hydroxide 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
Urinary pH changes alter renal tubular reabsorption of salicylic acid, with weaker effect than systemic alkalinizers.
What to do
No routine action is needed; monitor salicylate levels or response when high-dose therapy is started or an antacid is added or stopped.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
