Common Side Effects of Advil
Advil (ibuprofen) often causes stomach upset, heartburn, nausea, vomiting, gas, bloating, constipation, or diarrhea. These affect up to 10-20% of users, especially at higher doses or with long-term use.[1][2]
Serious Gastrointestinal Risks
Ibuprofen increases the risk of stomach ulcers, bleeding, or perforation, particularly in older adults, those on blood thinners, alcohol users, or smokers. Symptoms include black stools, severe abdominal pain, or vomiting blood. The FDA warns of a 2-4 times higher risk compared to no NSAID use.[1][3]
Cardiovascular Concerns
Long-term or high-dose use raises chances of heart attack, stroke, or heart failure, especially in people with heart disease or risk factors. The FDA requires a boxed warning: risk starts within weeks and grows with duration.[1][4]
Kidney and Liver Issues
It can reduce kidney function, leading to acute kidney injury, especially in dehydrated people, those with kidney disease, or on diuretics/ACE inhibitors. Rare liver damage includes jaundice or hepatitis. Monitor in at-risk patients.[1][2]
Allergic Reactions and Asthma Risks
Rare but severe: rash, itching, swelling, dizziness, or anaphylaxis. Those with aspirin-sensitive asthma face worsened breathing (affecting 5-10% of asthmatics).[1][3]
Who Should Avoid Advil
Pregnant people (especially third trimester), those with ulcers, bleeding disorders, severe kidney/liver/heart disease, or upcoming surgery. Limit to lowest dose/shortest time in others.[1][4]
Drug Interactions
Combines poorly with aspirin (reduces heart benefits), other NSAIDs, blood thinners (bleeding risk), SSRIs (GI bleed risk), or methotrexate (toxicity).[2][3]
Overdose Dangers
Symptoms include nausea, vomiting, drowsiness, seizures, low blood pressure, or coma. Seek immediate help; no specific antidote exists.[1]
