Changes of antihistamine sales patterns in central Ukraine shows the impacts of both global warming and increased ragweed sensitization

Abstract

Analysis of the long-term trends of antihistamine sales in central Ukraine shows seasonal peaks of sales of these drugs associated with intense grass and to a lesser extent with tree pollen seasons. The shift of these peaks to earlier periods in 2015-2016 compared with 2008-2009 suggests evidence of global warming and climate change. However, the last two years revealed a new pattern of antihistamine drug sales perhaps due to increased sensitization of the local population to ragweed.
