Does Advil interact with antacids?
Advil (ibuprofen) has minimal direct interactions with antacids like Tums (calcium carbonate), Maalox (aluminum hydroxide/magnesium hydroxide), or Gaviscon. Antacids can slightly reduce ibuprofen absorption by increasing stomach pH, but this effect is small and doesn't usually require dose adjustments. Taking them together is generally safe.[1][2]
How should you time Advil and antacids?
Separate them by 30 minutes to 2 hours to avoid any minor absorption impact. Take Advil with food or milk if stomach upset occurs, as antacids don't protect against ibuprofen's GI irritation.[1][3]
Why might antacids affect ibuprofen?
Antacids neutralize stomach acid, potentially slowing ibuprofen dissolution and uptake in the small intestine. Studies show up to 20% less absorption with high-dose antacids, but peak blood levels still occur within 1-2 hours.[2][4]
Risks of combining them long-term?
No major risks, but chronic use of both raises chances of GI issues like ulcers from ibuprofen, unrelated to the antacid interaction. Monitor for heartburn or bleeding.[3][5]
What about other pain relievers and antacids?
- Tylenol (acetaminophen): No interaction; safe together.
- Aspirin: Similar minor absorption dip; avoid high NSAID combos.
- Naproxen (Aleve): Like ibuprofen, slight delay but okay.[1][2]
When to check with a doctor?
If you have kidney issues, high blood pressure, or take blood thinners, as ibuprofen alone poses risks—antacids don't change that. Pregnant or elderly users should consult first.[3][5]
