Read the full list
Interaction LookupAnti-rejection drug interaction lookup: search by drug, ingredient, Taiwan brand name, food or supplement; each record has sources, verification date and limits; generates a question list for your doctor or pharmacist. Fixed database — "not found" does not mean safe; no dosing advice. Potassium · Phosphorus · Calcium LookupType a food name (Chinese, English, Japanese or Korean), or pick a category and sort by potassium or phosphorus. Values are mg per 100 g edible portion; a typical serving is shown too.

The three rules that matter most

  1. 1Anything marketed to "boost immunity" works against your anti-rejection drugs — always ask your doctor or pharmacist first
  2. 2Use acetaminophen for pain, never NSAIDs; if you get COVID, tell the prescriber you are a transplant recipient (Paxlovid)
  3. 3Re-check your level 5–7 days after any new drug; on lab day draw the trough before the morning dose
  4. 4In Taiwan, at every clinic, dentist or pharmacy, ask staff to read your NHI IC-card orders and cloud medication record (雲端藥歷) — the most direct way to catch duplicate or interacting prescriptions
