Fenofibrate

First-line treatment for severe hypertriglyceridemia (triglycerides of 10 mmol/L or higher), a level that carries a real risk of acute pancreatitis if left untreated.

Not recommended during pregnancy; safety data are limited, and fibrates are generally avoided unless triglycerides are severely elevated and the risk of pancreatitis to the mother outweighs the uncertainty — this is a decision made together with your doctor.

Not recommended while breastfeeding, since it's not known whether fenofibrate passes into breast milk in significant amounts — discuss alternatives or timing with your pharmacist or doctor.

Not commonly used in children; fenofibrate is primarily a treatment for adults, and any pediatric use for a severe inherited lipid disorder would be guided by a specialist.

GI upset (nausea, abdominal pain), Headache, Muscle aches, Elevated liver enzymes, Gallstones with long-term use

Report unexplained muscle pain, tenderness, or weakness promptly, especially if combined with a statin, since this can signal a serious muscle problem; also watch for signs of gallstones (upper right abdominal pain) or liver problems (yellowing skin or eyes, unusual fatigue).

Fenofibrate activates PPAR-alpha receptors, which increases the breakdown of triglyceride-rich particles and reduces how much triglyceride the liver produces, substantially lowering triglyceride levels.

Contraindicated in hepatic impairment, significant kidney dysfunction, and gallbladder disease, per the protocol. If a fibrate needs to be combined with a statin, gemfibrozil should never be the fibrate used, given a serious interaction risk — fenofibrate is the safer choice in this situation, though any statin-fibrate combination still calls for monitoring for muscle symptoms.

Should never be combined with the fibrate gemfibrozil due to a serious interaction risk; combining with a statin increases the chance of muscle-related side effects and calls for monitoring, and it can also increase the effect of warfarin.

Depending on the specific formulation, some fenofibrate products are best taken with food to improve absorption — follow the instructions for your specific product, since this varies by brand.

Taken once daily by mouth; whether it should be taken with or without food depends on the specific formulation you're prescribed, so follow your product's instructions or your pharmacist's guidance.

Store at room temperature, away from moisture, out of reach of children.

Report any new muscle pain, tenderness, or weakness promptly, and keep your follow-up appointments with the lipid clinic, since severely elevated triglycerides need ongoing monitoring.

Dosing depends on the specific formulation prescribed, taken by mouth on an ongoing basis pending follow-up with a lipid clinic.

Triglyceride levels typically drop substantially within a few weeks of starting, reducing the risk of pancreatitis; blood tests are used to track your response, with ongoing follow-up through your lipid clinic.
