While there were proof-of-concept studies to use H1R antagonists to improve COVID-19 treatment paradigms, all these studies were quite limited and lacked placebo control. The addition of antihistamines seems reasonable and may even have other beneficial effects like the ACE2 interaction of desloratadine. However, there seems to be a lack of placebo-controlled studies, and current research seems to be the result of small tests conducted during the pandemic.
