Fluconazole + Lovastatin

MAJOR — Use With Caution

🔴 CAUTION — Major interaction between Lovastatin and Fluconazole. Avoid unless under direct medical supervision.

Evidence level: STRONG

What this interaction means

Diflucan increases Mevacor levels dangerously. Risk of rhabdomyolysis (muscle breakdown).

How it works (mechanism)

CYP3A4 inhibition by fluconazole increases lovastatin levels → rhabdomyolysis risk.

Practical advice

Lovastatin affects how your body processes Fluconazole, which may change its effectiveness. Your doctor may need to adjust dosages or consider an alternative. Do not change doses on your own.

Timing

Take Lovastatin in the evening when hepatic cholesterol synthesis peaks (exception: atorvastatin and rosuvastatin have long half-lives and can be taken any time). Fluconazole can be taken at a separate meal. Report unexplained muscle pain, weakness, or dark urine immediately.

Risk factors

Higher risk with: liver impairment, genetic CYP enzyme variations (poor or ultra-rapid metabolizers), older age, polypharmacy (many medications).

Symptoms to watch for

Monitor for any unusual symptoms and report them to your healthcare provider promptly.

What to tell your doctor

Ask your doctor: "Is there a safer alternative to Fluconazole that I can take with Lovastatin?" Bring a list of ALL supplements and medications you take.

Safer alternatives

Statin interactions often involve liver enzyme competition. Ask your doctor about alternative statins (rosuvastatin and pravastatin have fewer CYP interactions) or spacing doses 12 hours apart. CoQ10 supplementation may help with statin-related muscle discomfort.
