Acetaminophen (paracetamol)
Medication
Evidence of harm: Moderate
Often Listed — Weak EvidenceThis item appears on some internet lists, but current evidence does not clearly support routine avoidance at normal exposure levels.
- Why it matters
- Often listed online as risky, but high-quality studies do not show meaningful hemolysis at recommended therapeutic doses. Generally the preferred analgesic and fever reducer in G6PD deficiency. Overdose can still cause hemolysis (and liver injury) — stay within label dosing.
- Symptoms to monitor
- Routine medication monitoring at therapeutic doses.
- What to ask your doctor / pharmacist
- What is the right dose for me or my child, and what is the daily maximum?
Ibuprofen and other NSAIDs
Medication

Food
Evidence of harm: Moderate
Use CautionUse only after discussing your G6PD status, dose, and monitoring plan with your clinician or pharmacist.

- What to ask your doctor / pharmacist
- Are there animal-protein or rice-protein alternatives I can use instead?
High-concentration vitamin C (ascorbic acid supplements, fortified drinks)
Food
Evidence of harm: Moderate
Use CautionUse only after discussing your G6PD status, dose, and monitoring plan with your clinician or pharmacist.
- Why it matters

- Why it matters
- Infection is the single most common trigger of hemolysis in G6PD deficiency — more common than food or medication. Always tell the clinician treating an infection that you have G6PD deficiency so they avoid sulfa drugs, nitrofurantoin, and other triggers.
- Symptoms to monitor
- Dark/cola-colored urine, jaundice, pallor, or extreme fatigue during an illness — seek urgent medical care.
