Why does Advil (ibuprofen) upset your stomach?
Yes. Advil (ibuprofen) commonly irritates the stomach and can cause indigestion or stomach pain. It’s an NSAID (nonsteroidal anti-inflammatory drug), and NSAIDs can reduce protective stomach substances (prostaglandins), making the stomach lining more vulnerable to irritation and ulcers.
What stomach symptoms can happen?
People may notice:
- Heartburn or burning in the chest
- Nausea
- Stomach pain or cramping
- Upset stomach/indigestion
- Bloating or feeling unusually full
These effects are often more likely with higher doses, taking it on an empty stomach, or using it more days in a row.
Can it cause ulcers or GI bleeding?
Ibuprofen can increase the risk of stomach or intestinal ulcers and bleeding. The risk is higher if you:
- Take NSAIDs often or at higher doses
- Are older
- Have a history of ulcers or GI bleeding
- Use blood thinners or steroids
- Drink alcohol regularly
Seek urgent care if you have signs of bleeding, such as black/tarry stools, vomiting blood, or severe/worsening abdominal pain.
Does taking Advil with food help?
Taking ibuprofen with food can reduce stomach upset for many people. Using the lowest effective dose for the shortest time also lowers risk.
What can I do if Advil upsets my stomach?
If you’re getting stomach symptoms:
- Avoid taking it on an empty stomach.
- Consider whether you can use a different pain/fever option that’s gentler on the stomach (many people use acetaminophen instead, if it’s appropriate for them).
- If symptoms persist or are severe, stop and talk with a clinician about safer alternatives and your risk factors.
When should you not take it?
Talk to a clinician before using ibuprofen if you have a history of ulcers/GI bleeding, take medications that affect bleeding, or have been told to avoid NSAIDs.
