G6PD deficiency: medicines to avoid

G6PD protects red blood cells from oxidative stress. Some medicines can increase that stress and trigger haemolysis in susceptible people. The safe choice depends on the exact active ingredient, formulation, dose and your health situation, so a general internet list may be incomplete or confusing. Brand names can differ between countries. Tell the prescriber about G6PD deficiency and show the packaging to a pharmacist before using a new product.

Carry a written G6PD alert and keep your medication list updated. Check prescriptions, painkillers, antibiotics, antimalarial medicines, cold remedies, supplements and herbal preparations before use. Do not stop an essential prescribed treatment abruptly; contact the prescriber for a safe alternative. If a medicine was taken accidentally, call a healthcare professional and provide its name, strength and time taken. A Blood Test may be used if symptoms suggest haemolysis or anaemia.

Seek urgent advice after a new medicine if you develop yellow eyes or skin, Dark Urine, Pale Skin, unusual weakness, breathlessness, dizziness or a racing heartbeat. Emergency care is needed for fainting, chest pain, severe breathing difficulty, confusion or rapid worsening. Bring the medicine packet if possible.

Ask which ingredients you should avoid, how to check a substitute, what to do after an accidental dose, and whether family members need advice or testing.
