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. Piroxicam is contraindicated in the setting of coronary artery bypass graft 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 .
Uses for Feldene
Piroxicam is a nonsteroidal anti-inflammatory drug (NSAID) used to treat pain and help relieve symptoms of arthritis (eg, osteoarthritis, rheumatoid arthritis), such as inflammation, swelling, stiffness, and joint pain. However, this medicine does not cure arthritis and will help you only as long as you continue to use it.
This medicine is available only with your doctor's prescription.
Before using Feldene
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. For non-prescription products, read the label or package ingredients carefully.
Appropriate studies have not been performed on the relationship of age to the effects of piroxicam in the pediatric population. Safety and efficacy have not been established.
Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of piroxicam in the elderly. However, elderly patients may be more sensitive to the stomach side effects (eg, ulcers, bleeding) of piroxicam than younger adults, and are more likely to have age-related kidney problems, which may require caution and an adjustment in the dose for patients receiving piroxicam.
There are no adequate studies in women for determining infant risk when using this medication during breastfeeding. Weigh the potential benefits against the potential risks before taking this medication while breastfeeding.
