In 2013, the condition of the OTC market (medicines and dietary supplements, pharmacy and non-pharmacy sales in Poland) significantly improved, mainly, due to the market stabilization after the falls recorded in 2012 (a result of the Reimbursement Act implementation). The OTC market depends on epidemiological trends. High flu incidence was the key factor which boosted sales in 2013, with special regard to OTC drugs (with continuous high infections rate, the similar situation is predicted for 2014; however, the base level reached in 2013 shall prevent the generation of comparatively high growth rates in 2014).
