Levonorgestrel and mycophenolic acid

Mycophenolic acid's FDA label of July 29, 2026 names levonorgestrel in its drug interactions section; the levonorgestrel labels PlainMeds reads (4) do not name mycophenolic acid. The mycophenolic acid label: “In a drug interaction study, mean levonorgestrel AUC was decreased by 15% when coadministered with MMF.”
