Uses for Ansaid

Flurbiprofen is a nonsteroidal anti-inflammatory drug (NSAID) used to relieve symptoms of arthritis (osteoarthritis and 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 take it.

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

Before using Ansaid

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 have not been performed on the relationship of age to the effects of flurbiprofen in the pediatric population. Safety and efficacy have not been established.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of flurbiprofen in the elderly. However, elderly patients are more likely to have age-related kidney, stomach, or heart problems, which may require caution and an adjustment in the dose for patients receiving flurbiprofen.
