Scientific American reports that penicillin allergy is more common in women than men, according to the Annals of Allergy, Asthma, and Immunology.
The study found than penicillin allergy is more likely to develop in women, even after factoring in the effects of other allergy risk factors.
Dr. Miguel A. Park of the Mayo Clinic notes that one to 10 percent of the population reports having penicillin allergy, while the rate of life-threatening reactions to this antibiotic is estimated to be 0.01 percent to 0.05 percent.
‘Females were also 2.6 times more likely than males to report multiple drug allergies,’ reports Park's research team. Other studies have also found that being female is a risk factor for adverse drug reactions in general.
