Ibuprofen is classified as a nonsteroidal anti-inflammatory drug (NSAIDs). It is used to treat mild to moderate pain and helps to relieve symptoms of arthritis, such as inflammation, swelling, stiffness and joint pain, states the Mayo Clinic. Pregnant women should avoid Ibuprofen due to the risk of birth defects. The highest recommended dosage is 800 milligrams (mg), because at this amount, it can trigger mild to severe side effects.

Gastrointestinal Effects

Taking 800 mg of Ibuprofen may cause gastrointestinal effects. Symptoms include nausea, heartburn, constipation, bloating, flatulence and diarrhea. Taking your medication with food may help decrease side effects. Ibuprofen and other NSAIDs can also increase your risk of serious effects on the stomach or intestines, including bleeding or perforation, states Drugs.com. This can be a medical emergency. Ibuprofen may also contribute to the development of gastric ulcers, which may be painful and cause bleeding. If you are taking Ibuprofen and experience severe stomach pain, vomiting blood, or black or bloody stools, seek immediate medical attention.
