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. Oxaprozin is contraindicated in the setting of CABG surgery. NSAIDs can also 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 .

Before Using Daypro
In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For this medicine, the following should be considered:
Tell your doctor if you have ever had any unusual or allergic reaction to this medicine or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals.

Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of oxaprozin in children 6 to 16 years of age. Safety and efficacy have not been established in children younger than 6 years of age.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of oxaprozin in the elderly. However, elderly patients may be more sensitive to the effects of oxaprozin than younger adults, and are more likely to have age-related heart, stomach, or kidney problems, which may require an adjustment in the dose of patients receiving oxaprozin.
