Fenofibrate

What is fenofibrate?

Fenofibrate is a fibric acid derivative used as an anti-lipemic agent to lower triglycerides (a type of fat or lipid) in dogs. Its use in cats and other animals has not been studied. 

It is used off label (extra label) in veterinary medicine. Many drugs are commonly prescribed for off-label use in veterinary medicine. “Off label” means the drug is being used in a way that has not been reviewed or approved by the U.S. Food and Drug Administration (FDA) or Health Canada. In these instances, follow your veterinarian’s directions and cautions carefully, as they may be significantly different from those on the label.

How do I give my pet fenofibrate?

Fenofibrate comes in capsule and tablet forms.

• Both forms are given orally (by mouth).
• Fenofibrate comes in many formulations that may not be bioequivalent – confirm with your veterinarian you are using the appropriate formulation.
• This medication is given with food, usually the first meal of the day.
• Give this medication to your pet for the entire time prescribed by your veterinarian, even if it appears that your pet is feeling better.

This medication should take effect within a few hours, though effects may not be outwardly visible.

What if I miss giving my pet the medication?

Give the missed dose as soon as you remember and then wait the recommended time as prescribed by your veterinarian for the next dose. Do not give the pet two doses at once.

Are there any potential side effects from fenofibrate?

Fenofibrate may cause the following side effects:

• flatulence and/or diarrhea
• loss of appetite, nausea

The following reactions are rare, but if they occur, contact your veterinarian immediately:

• an allergic reaction such as irregular breathing, rash, fever, puffiness and swelling around the face

Drug sensitivities can develop over time with repeated exposure. Your pet may have no reaction after the first few doses, but may develop a sensitivity later. It is important to watch for signs of an allergic reaction over the entire course of treatment. Other side effects may occur. If you notice anything unusual, contact your veterinarian immediately.

This medication is short-acting, meaning that effects will last about 24 hours, though effects may last longer in pets with kidney or liver disease.
