Case study suggests antihistamines provide relief for long COVID-19

Antihistamines may provide relief from long COVID-19 symptoms according to a case report co-authored by nursing scholars at the University of California, Irvine (UCI). The case report, published in The Journal for Nurse Practitioners, describes two healthy middle-aged women with long COVID who, by chance, discovered over-the-counter antihistamines greatly enhanced their daily function, an improvement they sustained for almost a year. “The next steps for this research into antihistamine treatment are to conduct broad-based trials in order to evaluate efficacy and to develop dosage schedules for clinical practice guidelines,” said study co-author Melissa Pinto, PhD, RN, UCI associate professor of nursing.
