Dr. Huang Shenggang reply Pharmacology

G6PD deficiency is a common X-linked hereditary metabolic disorder.
G6PD is an important enzyme in the metabolic process of glucose in red blood cells.
When glutathione (G-SH) in red blood cells is oxidized by external oxidants, the lack of G6PD prevents it from being reduced back to G-SH, which protects the cell membrane of red blood cells, leading to hemolysis.
The following medications should be avoided by patients with favism: antimalarial drugs such as primaquine, pamaquine, pentaquine, and plasmoquine; sulfonamide antibiotics such as sulfanilamide, sulfapyridine, sulfisoxazole, sulfacetamide, salicylazosulfapyridine, and sulfamethoxypyridazine; analgesics and antipyretics such as aspirin, acetanilide, phenacetin, antipyrine, aminopyrine, and p-aminosalicylic acid; antiseptics and disinfectants such as nitrofurantoin, furazolidone, and furaltadone; and other substances such as naphthalene, gentian violet, methylene blue, phenylhydrazine, acetylphenylhydrazine, probenecid, and sulfoxone.
Regarding neomycin ointment, it can generally be recommended unless there is an allergy to the ingredient neomycin.

More Info

Favism, or G6PD deficiency, is a genetic condition that affects the enzyme glucose-6-phosphate dehydrogenase, which plays a crucial role in protecting red blood cells from damage. Individuals with this condition can experience hemolytic anemia when exposed to certain triggers, including specific medications, foods (like fava beans), and even some topical agents. Therefore, it is essential to be cautious when selecting ointments or topical treatments for individuals with favism.

Safe Ointments for Individuals with Favism
1. Avoid Certain Ingredients: Individuals with favism should avoid topical products that contain certain ingredients known to trigger hemolysis. These include:
- Benzocaine: Often found in topical anesthetics, it can cause hemolytic reactions in G6PD-deficient individuals.

- Methylene Blue: Sometimes used in antiseptic solutions, it is contraindicated for those with G6PD deficiency.

- Certain Essential Oils: Some essential oils may also pose risks, so it's best to consult with a healthcare provider before use.

2. Recommended Ointments: When treating minor cuts, scrapes, or skin irritations, consider the following options that are generally considered safe for individuals with favism:
- Plain Petroleum Jelly (Vaseline): This is a safe and effective option for protecting minor wounds and keeping them moist.

- Aloe Vera Gel: Known for its soothing properties, pure aloe vera gel can be used for minor burns or skin irritations.

- Hydrocortisone Cream: Low-strength hydrocortisone cream (1%) can be used for mild inflammation or itching, but it should be used sparingly and not for extended periods.

- Antibiotic Ointments: Products like Neosporin (which contains bacitracin, neomycin, and polymyxin B) are generally safe, but it’s always best to check with a healthcare provider before use.

3. Consultation with Healthcare Providers: Before using any new ointment or topical treatment, individuals with favism should consult with their healthcare provider or a pharmacist. They can provide guidance on safe options and help avoid any potential triggers.

4. Patch Testing: If trying a new product, consider performing a patch test on a small area of skin to check for any adverse reactions before applying it more broadly.

5. Monitoring for Reactions: After applying any ointment, monitor for any signs of an allergic reaction or hemolytic episode, such as jaundice, dark urine, fatigue, or shortness of breath. If any of these symptoms occur, seek medical attention immediately.

Conclusion
In summary, individuals with favism should be cautious when selecting ointments and topical treatments. It is crucial to avoid products containing known triggers and to opt for safer alternatives like petroleum jelly and aloe vera. Always consult with a healthcare provider for personalized advice and recommendations. By taking these precautions, individuals with favism can manage their skin care needs safely and effectively.
