Aspirin and nonsteroidal anti-inflammatory drugs, or NSAIDs, are both drugs
used to treat pain, redness, swelling, and inflammation from a variety of
medical conditions like menstrual cramps, arthritis, minor strains and sprains,
and headaches. Aspirin also treats fever. Aspirin also is an NSAID, but it works
in the body differently than other NSAIDs.
Some of the common side effects of aspirin and NSAIDS are nausea, vomiting, diarrhea, constipation, loss of appetite, peptic ulcers, and tinnitus. NSAIDs also can cause dizziness, headache, and drowsiness. Important and serious side effects of both drugs are kidney or liver failure, GI bleeding, and prolonged bleeding after surgery.
Aspirin and nonsteroidal anti-inflammatory drugs have other important side effects and drug interactions that should be reviewed prior to taking either drug.
