Uses for Clinoril

Sulindac is a nonsteroidal anti-inflammatory drug (NSAID) used to treat mild to moderate pain and help relieve symptoms of arthritis (e.g., osteoarthritis and rheumatoid arthritis) or acute gout, such as inflammation, swelling, stiffness, and joint pain. This medicine does not cure arthritis and will help you only as long as you continue to take it.

Sulindac is also used to treat ankylosing spondylitis, which is a type of arthritis that affects the joints in the spine. This medicine may also be used to treat painful shoulder (bursitis or tendinitis).

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

Before using Clinoril

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 sulindac 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 sulindac in the elderly. However, elderly patients may be more sensitive to the effects of sulindac than younger adults, and are more likely to have age-related kidney problems, which may require an adjustment in the dose for patients receiving sulindac.

Breast Feeding

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.
