Uses For fenofibrate


Fenofibrate is used together with a proper diet to treat high cholesterol and triglyceride (fat-like substances) levels in the blood. This may help prevent the development of pancreatitis (inflammation of the pancreas) caused by high levels of triglycerides in the blood.


fenofibrate is available only with your doctor's prescription.


Before Using fenofibrate


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 fenofibrate, the following should be considered:


In addition to its helpful effects in treating your medical problem, this type of medicine may have some harmful effects. Results of large studies using other agents that are similar to fenofibrate seem to suggest that fenofibrate may increase the patient's risk of cancer, pancreatitis (inflammation of the pancreas), gallstones, and problems from gallbladder surgery. Studies with fenofibrate in rats found an increased risk of liver and pancreatic tumors when doses up to 6 times the human dose were given for a long time. Be sure you have discussed this with your doctor before taking fenofibrate.


Allergies


Tell your doctor if you have ever had any unusual or allergic reaction to fenofibrate 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 fenofibrate 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 fenofibrate in the elderly. However, elderly patients are more likely to have age-related kidney problems, which may require caution and an adjustment in the dose for patients receiving fenofibrate.
