Uses for Clinoril

Sulindac is a nonsteroidal anti-inflammatory drug (NSAID) that helps treat mild to moderate pain and relieve symptoms of arthritis, like osteoarthritis and rheumatoid arthritis, or acute gout. It can reduce inflammation, swelling, stiffness, and joint pain. This medicine does not cure arthritis and will only help you as long as you keep taking it.

Sulindac is also used to treat ankylosing spondylitis, a type of arthritis that affects the spine joints. It may also be used for painful shoulder conditions, such as bursitis or tendinitis.

You can only get this medicine with your doctor's prescription.

Precautions while using Clinoril

It is very important for your doctor to check your progress at regular visits to ensure that the medicine is working properly. Blood and urine tests may be needed to look for unwanted effects.

This medicine may increase your risk of having a heart attack or stroke. This is more likely in people who already have heart disease. People who use this medicine for a long time may also have a higher risk.

This medicine may cause bleeding in your stomach or intestines. These issues can occur without warning signs. This is more likely if you have had a stomach ulcer in the past, if you smoke or drink alcohol regularly, are over 60 years old, are in poor health, or if you are taking certain other medicines (such as a steroid medicine or a blood thinner).

Serious skin reactions can happen during treatment with this medicine. Contact your doctor immediately if you have any of the following symptoms while taking this medicine: blistering, peeling, loosening of the skin; chills; cough; diarrhea; fever; itching; joint or muscle pain; red skin lesions; sore throat; sores, ulcers, or white spots in the mouth or on the lips; or unusual tiredness or weakness.

Some possible warning signs of serious side effects that can happen during treatment with this medicine may include black, tarry stools; decreased urination; severe stomach pain; skin rash; swelling of the face, fingers, feet, or lower legs; unusual bleeding or bruising; unusual weight gain; vomiting blood or material that looks like coffee grounds; or yellow skin or eyes. Also, signs of serious heart problems could occur, such as chest pain, fast or irregular heartbeat, tightness in the chest, unusual flushing or warmth of skin, weakness, or slurring of speech. Stop taking this medicine and contact your doctor right away if you notice any of these warning signs.

This medicine may cause a serious allergic reaction called anaphylaxis. Although this is rare, it may happen more often in patients who are allergic to aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs). Anaphylaxis can be life-threatening and requires immediate medical attention. The most serious signs of this reaction are very fast or irregular breathing, gasping for breath, wheezing, or fainting. Other signs may include a change in the color of the face; very fast but irregular heartbeat or pulse; hive-like swellings on the skin; and puffiness or swelling of the eyelids or around the eyes. If these effects occur, seek emergency help immediately.

Using this medicine during late pregnancy can harm your unborn baby. If you think you have become pregnant while using the medicine, inform your doctor right away.

This medicine may cause issues with your pancreas. Contact your doctor immediately if you have any of the following symptoms while taking this medicine: bloating; chills; constipation; darkened urine; fast heartbeat; fever; indigestion; loss of appetite; nausea; pain in the stomach, side, or abdomen, possibly radiating to the back; vomiting; or yellow eyes or skin.

Contact your doctor immediately if you experience blurred vision, difficulty reading, or any other change in vision during or after your treatment. Your doctor may want you to have your eyes checked by an ophthalmologist (eye doctor).

Call your doctor right away if you have confusion, drowsiness, a fever, a general feeling of illness, a headache, loss of appetite, nausea, a stiff neck or back, or vomiting. These could be symptoms of meningitis.

Before having any kind of surgery or medical tests, inform your doctor that you are taking this medicine. It may be necessary for you to stop treatment for a while or to switch to a different nonsteroidal anti-inflammatory drug before your procedure.

Do not take other medicines unless you have discussed them with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines and herbal or vitamin supplements.

Before using Clinoril

In deciding to use a medicine, the risks of using the drug must be weighed against the good it will do. This is a decision you and your doctor will make. For this medication, the following should be considered:

Allergies

Tell your clinician if you have ever had any unusual or allergic reaction to this medicine or any other drugs. Also inform 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 issues 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 medicine during breastfeeding. Weigh the potential benefits against the potential chances prior to taking this medicine while breastfeeding.

Interactions with Drugs

Although certain medications should not be used together at all, in other cases two different medications may be used together even if an interaction might occur. In these cases, your clinician may want to change the dose, or other precautions may be necessary.

The following interactions have been selected on the basis of their potential significance and are not necessarily all-inclusive.
