Is ibuprofen an antacid, or something else?
No. Ibuprofen is a pain-reliever and anti-inflammatory (a nonsteroidal anti-inflammatory drug, or NSAID). It is not an antacid and does not neutralize stomach acid.
What does an antacid actually do?
Antacids are medicines designed to reduce heartburn by neutralizing stomach acid (for example, products containing calcium carbonate, magnesium hydroxide, or aluminum hydroxide). Ibuprofen does not work this way.
Can ibuprofen cause stomach acid problems anyway?
Yes. Because ibuprofen is an NSAID, it can irritate the stomach lining and raise the risk of stomach ulcers or bleeding in some people. That means it can worsen symptoms like heartburn or indigestion for certain users, even though it is not an antacid.
What should you take for heartburn instead of ibuprofen?
For heartburn specifically, people typically use antacids or acid-reducing medicines (depending on symptoms and duration), rather than ibuprofen. If you’re treating pain and heartburn at the same time, it can be important to choose the right medication and avoid worsening stomach irritation.
When to get medical help
Seek medical care urgently if heartburn or indigestion comes with vomiting blood, black/tarry stools, trouble swallowing, chest pain, or symptoms that don’t improve.
