Can You Crush Fenofibrate?

No, fenofibrate tablets should not be crushed. Fenofibrate formulations are specifically designed with particle size modifications (micronized or nanoparticle formulations) to enhance the bioavailability of this highly lipophilic, water-insoluble drug, and crushing would destroy these pharmaceutical properties 1.

Why Crushing Is Problematic

Fenofibrate's absorption depends critically on its formulation technology. The drug is virtually insoluble in water and poorly absorbed in its native state 1. Modern formulations use:

• Micronized particles with reduced particle sizes for greater solubility and improved bioavailability 1
• Nanoparticle formulations that allow absorption without food requirements 1
• Film-coating materials containing specific excipients (hypromellose, macrogol, polydextrose, titanium dioxide, triacetin) that control drug release 2

Crushing the tablet would eliminate these carefully engineered properties, potentially resulting in:

• Unpredictable and likely reduced drug absorption 1
• Loss of the food-independent absorption characteristic of newer formulations 1
• Altered pharmacokinetics that could lead to either underdosing (therapeutic failure) or overdosing (increased toxicity risk) 1

Critical Safety Considerations

Different fenofibrate formulations are NOT equivalent on a milligram-to-milligram basis 1. The 67 mg and 200 mg micronized capsules are equivalent to the 54 mg and 160 mg suprabioavailable tablets, respectively 3. Healthcare providers must recognize that crushing could create serious medication errors 1.

Alternative Approaches for Patients with Swallowing Difficulties

If a patient cannot swallow tablets:

• Consult with a pharmacist about whether a fenofibric acid choline salt formulation might be available, as this has the highest bioavailability among marketed formulations 1
• Consider alternative fibrate formulations if available in liquid or other forms
• Evaluate whether the patient truly requires fenofibrate versus alternative lipid management strategies, particularly given that fenofibrate is contraindicated in severe renal impairment (eGFR <30 mL/min/1.73m²) and requires dose reduction in moderate renal impairment 4, 2

Monitoring Requirements If Fenofibrate Is Essential

If fenofibrate therapy is deemed necessary despite administration challenges:

• Assess renal function (serum creatinine and eGFR) before starting, within 3 months of initiation, and every 6 months thereafter 4
• Monitor hepatic transaminases at baseline and as clinically indicated 4
• Discontinue if persistent ALT elevations ≥3 times upper limit of normal occur 4
