Risk of Serious Cardiovascular and Gastrointestinal EventsNonsteroidal anti-inflammatory drugs (NSAIDs) cause an increased risk of serious cardiovascular thrombotic events, including myocardial infarction and stroke, which can be fatal. This risk may occur early in treatment and may increase with duration of use.Naproxen sodium/sumatriptan succinate is contraindicated in the setting of coronary artery bypass graft (CABG) surgery.NSAIDs cause an increased risk of serious gastrointestinal (GI) adverse events including bleeding, ulceration, and perforation of the stomach or intestines, which can be fatal. These events can occur at any time during use and without warning symptoms. Elderly patients and patients with a prior history of peptic ulcer disease and/or GI bleeding are at greater risk for serious GI events.

5-HT1 agonists:

Frequency not reported: Transient and permanent blindness and significant partial vision loss[Ref]



-Frequency not reported: renal papillary necrosis, renal toxicity

-Postmarketing reports: Fetal kidney problems resulting in low amniotic fluid[Ref]

US FDA Drug Safety Communication (10-2020): The FDA is requiring a new warning be added to NSAID labeling describing the risk of fetal kidney problems that may result in low amniotic fluid. The FDA is recommending pregnant women avoid NSAID use at 20 weeks gestation or later. Through 2017, the FDA has received 35 reports of low amniotic fluid levels or kidney problems in mothers who took NSAIDs while pregnant. Five newborns died; 2 had kidney failure and confirmed low amniotic fluid, 3 had kidney failure without confirmed low amniotic fluid. The low amniotic fluid started as early as 20 weeks of pregnancy. There were 11 reports of low amniotic fluid levels during pregnancy and the fluid volume returned to normal after the NSAID was stopped. The medical literature has reported low amniotic fluid levels with use of NSAIDs for varying amounts of time, ranging from 48 hours to multiple weeks. Complications of prolonged oligohydramnios may include limb contractures and delayed lung maturation. In some postmarketing cases of impaired neonatal renal function, invasive procedures such as exchange transfusion or dialysis were required. In other cases, the condition was reversible within 3 to 6 days of stopping the NSAID and in these cases reappeared when the same NSAID was restarted.[Ref]



Frequency not reported: Exfoliative dermatitis, Stevens-Johnson syndrome, toxic epidermal necrolysis



Frequency not reported: Premature closure of ductus arteriosus[Ref]



Common (1% to 10%): Elevated liver tests

Frequency not reported: Severe hepatic reactions including jaundice, fatal fulminant hepatitis, liver necrosis, and hepatic failure[Ref]



Frequency not reported: Anemia[Ref]
