Practical advice

Complete your full course of Penicillin V as prescribed alongside Ezetimibe. Some antibiotics can temporarily alter how other drugs are metabolized. If you experience unusual side effects during the antibiotic course, contact your prescriber.

Timing

Some antibiotics (erythromycin, clarithromycin) strongly inhibit CYP3A4 and can dramatically increase statin levels, raising rhabdomyolysis risk. Take Ezetimibe in the evening as usual. Your prescriber may temporarily pause or reduce the statin during short antibiotic courses.

Risk factors

Higher risk for: those with liver impairment, genetic CYP enzyme variations (poor or ultra-rapid metabolizers), elderly, those on multiple CYP3A4 inhibitors, high-dose statin therapy, or history of myopathy.

Symptoms to watch for

Monitor for muscle and liver effects when combining Penicillin V with Ezetimibe. Watch for: unexplained muscle pain, tenderness, or weakness (especially if accompanied by fever or fatigue), dark-colored urine, yellowing of skin or eyes, or upper abdominal pain. Some drug combinations increase statin blood levels and raise the risk of rhabdomyolysis. When to seek emergency help: Severe muscle pain with weakness, dark brown urine, fever, confusion, rapid heartbeat, or signs of kidney failure (very little or no urination). Report any new muscle symptoms to your prescriber immediately.

What to tell your doctor

No urgent need to discuss, but always keep your doctor informed of your full supplement and medication list. Say: "I take Penicillin V and Ezetimibe — is that OK?"
