Usual Adult Dose for Dysmenorrhea

• Treatment should begin at the earliest onset of pain.

Use: For the relief of signs and symptoms of primary dysmenorrhea

Usual Adult Dose for Osteoarthritis

• Individualize dose; adjust dose up or down depending on severity of symptoms

Maximum dose: 3200 mg/day (prescription strength)

Comments:

• Patients with rheumatoid arthritis generally require higher doses than those with osteoarthritis.
• In chronic conditions, a therapeutic response may be seen in a few days to a week but most often is observed by 2 weeks; after a satisfactory response has been achieved, review and adjust dose to achieve the lowest dose that yields acceptable control.
• Individual patients may show a better response to 3200 mg/day compared with 2400 mg/day, although in well-controlled clinical trials, use of 3200 mg/day did not show a better mean response in terms of efficacy.

Use: For the relief of signs and symptoms of rheumatoid arthritis and osteoarthritis

Precautions

US BOXED WARNINGS: RISK OF SERIOUS CARDIOVASCULAR AND GASTROINTESTINAL EVENTS:

• Nonsteroidal anti-inflammatory drugs (NSAIDs) cause an increased risk of serious cardiovascular (CV) thrombotic events, myocardial infarction and stroke, which can be fatal. This risk may occur early in treatment and may increase with duration of use.
• This drug 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 a greater risk for serious GI events.

CONTRAINDICATIONS:
Oral Formulations:

• Known hypersensitivity to the active component (e.g., anaphylactic reactions and serious skin reactions) or any of the product ingredients
• History of asthma, urticaria, or other allergic-type reactions after taking aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs); severe, sometimes fatal, anaphylactic reactions to NSAIDs have been reported in such patients
• In the setting of coronary artery bypass graft (CABG) surgery

Parenteral:
Adults and Pediatric Patients 6 months or older (Caldolor):

• Hypersensitivity (e.g., anaphylactic reactions and serious skin reactions) to active substance or any product ingredients
• 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 surgery

Preterm Infants (NeoProfen):

• Proven or suspected infection that is untreated
• Congenital heart disease in which patency of the patent ductus arteriosus (PDA) is necessary for satisfactory pulmonary or systemic blood flow (e.g., pulmonary atresia, severe tetralogy of Fallot, severe coarctation of the aorta)
• Active bleeding, especially with active intracranial hemorrhage or GI bleeding
• Thrombocytopenia
• Coagulation defects
• Known or suspected necrotizing enterocolitis
• Significant renal impairment

Patient advice:

• Patients should be instructed to read the US FDA-approved patient labeling (Medication Guide for NSAIDs).
• Patients should seek medical advice for signs and symptoms of gastrointestinal events, adverse skin reactions, allergic reactions, hepatotoxicity, or unexplained weight gain or edema.
