Hello, in response to your question: According to the information provided by the United States Pharmacopeia regarding acetaminophen, favism is not listed as a caution or contraindication under normal dosing.
However, a 2002 article published in Pharmacotherapy reported a case of hemolysis in a Chinese male due to acetaminophen overdose.
Therefore, in patients with favism, excessive use should be avoided.

More Info
G6PD deficiency, also known as glucose-6-phosphate dehydrogenase deficiency, is a genetic condition that affects red blood cells and can lead to hemolytic anemia under certain stressors, including certain medications, infections, and foods. When it comes to the use of acetaminophen (commonly known as Tylenol or Paracetamol), the consensus among medical professionals is that it is generally considered safe for individuals with G6PD deficiency.
Acetaminophen is not known to cause oxidative stress in red blood cells, which is a significant concern for G6PD-deficient individuals. Unlike certain medications such as sulfonamides, nitrofurantoin, and some non-steroidal anti-inflammatory drugs (NSAIDs), acetaminophen does not have a documented association with hemolytic reactions in G6PD-deficient patients. This makes it a preferred choice for pain relief and fever reduction in this population.
However, it is essential to consider a few points when using acetaminophen:
1. Dosage: As with any medication, it is crucial to adhere to the recommended dosage guidelines. Overdosing on acetaminophen can lead to severe liver damage, which is a risk for everyone, not just those with G6PD deficiency.
2. Underlying Health Conditions: Individuals with G6PD deficiency may have other health issues that could complicate the use of acetaminophen. It is always best to consult with a healthcare provider to ensure that there are no contraindications based on the individual's overall health status.
3. Combination with Other Medications: If a person with G6PD deficiency is taking other medications, it is essential to check for potential interactions. While acetaminophen itself is safe, other medications taken concurrently may not be.
4. Monitoring for Symptoms: Although acetaminophen is generally safe, individuals with G6PD deficiency should be aware of their body's reactions. If any unusual symptoms occur after taking acetaminophen, such as jaundice, dark urine, or unusual fatigue, they should seek medical attention promptly.
5. Consultation with Healthcare Providers: It is always advisable for individuals with G6PD deficiency to consult with their healthcare provider or a specialist before starting any new medication, including over-the-counter drugs like acetaminophen. This ensures personalized medical advice based on their specific health needs.
In summary, acetaminophen is generally safe for individuals with G6PD deficiency, and it can be used for pain relief and fever management. However, as with any medication, it is essential to use it responsibly and under the guidance of a healthcare professional. If there are any concerns or if the individual has other health conditions, consulting a healthcare provider is the best course of action.
