Before taking any type of NSAID, tell your doctor if you drink alcohol or take blood thinners (including warfarin), ACE inhibitors, lithium or furosemide. Also report any sensitivity or allergy to aspirin or similar drugs. All non-aspirin NSAIDs may cause an increased risk of serious blood clots, heart attack and stroke, which can be fatal. This risk can occur as early as the first weeks using an NSAID and increases with dose and duration of use. Patients who have or who are at risk for cardiovascular disease are at greater risk for these complications than someone without cardiovascular disease or its risk factors. Treatment with NSAIDs following a first heart attack increases the risk of death in the first year after the heart attack (compared to not using NSAIDs after a first heart attack). NSAID use increases the risk of heart failure. NSAIDs should not be used for pain if you have had (or are about to have) coronary bypass surgery. Do not take NSAIDs late in pregnancy.
