G6PD deficiency allergy list: how to use it safely

G6PD deficiency is inherited. The enzyme normally helps red blood cells handle oxidative stress. Some medicines, chemical exposures, foods, and infections can overwhelm that protection in susceptible people, leading to haemolysis. This is different from an allergy, which is an immune reaction and may involve hives, swelling, or wheezing.

Lists can vary by local guidance, dose, illness, and the person’s medical history. A product’s brand name may hide its active ingredient, so check the generic name rather than relying on packaging or an internet list alone.

Tell every doctor, dentist, nurse, and pharmacist that you have G6PD deficiency. Carry the diagnosis in your phone or wallet. Before taking a new medicine, ask about the active ingredient, possible alternatives, and what symptoms should prompt a call. Do not discontinue a prescribed medicine abruptly unless a clinician tells you to.

If illness or a new exposure is followed by pale skin, yellowing, dark urine, dizziness, or unusual tiredness, arrange prompt medical review. A blood test can help investigate anaemia and haemolysis.

Go to urgent care for fainting, severe breathlessness, confusion, chest discomfort, profound weakness, or quickly worsening yellowing of the skin or eyes. These symptoms can mean that oxygen-carrying red blood cells are falling quickly.

Ask for a personalised written list, including medicines you may need during fever or travel. Also ask whether a family member needs testing, when repeat testing is useful, and which emergency symptoms matter most for you.
