Safety

Important Safety Information

WARNING: RISK OF SERIOUS CARDIOVASCULAR AND GASTROINTESTINAL EVENTS

Cardiovascular Thrombotic Events

Nonsteroidal 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.

ZUEINO is contraindicated in the setting of coronary artery bypass graft (CABG) surgery.

Gastrointestinal Bleeding, Ulceration, and Perforation

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.

Contraindications

Zueino is contraindicated in the following patients:

  • Known hypersensitivity (e.g., anaphylactic reactions and serious skin reactions) to diclofenac or any components of the drug product
  • History of asthma, urticaria, or other allergic-type reactions after taking aspirin or other NSAIDs. Severe, sometimes fatal, anaphylactic reactions to NSAIDs have been reported in such patients
  • In the setting of coronary artery bypass graft (CABG) surgery
  • Moderate to severe renal insufficiency in the perioperative period and who are at risk for volume depletion

Warnings and precautions

In addition to the Boxed Warning above, the Prescribing Information carries warnings and precautions for:

  • Hepatotoxicity — discontinue if abnormal liver tests persist or worsen, or if clinical signs and symptoms of liver disease develop
  • Hypertension — patients taking some antihypertensive medications may have an impaired response when taking NSAIDs; monitor blood pressure
  • Heart failure and edema; renal toxicity and hyperkalemia
  • Anaphylactic reactions; exacerbation of asthma related to aspirin sensitivity
  • Serious skin reactions, and drug reaction with eosinophilia and systemic symptoms (DRESS)
  • Fetal toxicity; hematologic toxicity; masking of inflammation and fever; laboratory monitoring

Most common adverse reactions

The most common adverse reactions (>5%) in controlled clinical trials include nausea, constipation, headache, infusion site pain, dizziness, flatulence, vomiting, and insomnia.
