This medicine does not cure arthritis and will help you only as long as you continue to take it.

This medicine is available only with your doctor's prescription.

  • Tablet

Before Using

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:

Allergies

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.

Pediatric

Appropriate studies on the relationship of age to the effects of oxaprozin have not been performed in children younger than 16 years of age. Safety and efficacy of oxaprozin in children has not been established.

Geriatric

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 caution and an adjustment in the dose of patients receiving oxaprozin.

Breastfeeding

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.
