[gotcha] Can I take my statin or blood pressure medication with grapefruit juice?

Warn against consuming grapefruit/grapefruit juice with medications metabolized by CYP3A4 \(like simvastatin, felodipine\) as it prevents breakdown, leading to toxic drug accumulation.

Journey Context:
A seemingly harmless dietary addition. Grapefruit contains furanocoumarins that irreversibly inhibit intestinal CYP3A4, effectively causing an overdose of the medication because the body cannot metabolize it. The effect can last 24\+ hours, so spacing the juice and the pill out does not fix it.
