Danish post-marketing pharmacosurveillance of spontaneous Oral Adverse Drug Reactions 2009-2019.

Health care professionals had a sporadic reporting pattern that seemed to be influenced by the debate in the community and in professional circles but also by the information in the SmPC of the drugs. The results indicate some reporting stimulation of OADRs in relation to Gardasil 4, Septanest, Eltroxin and MRONJ. Eventually the knowledge of OADRs increases but there is a risk of skewed information if reporting is not systematic, reliable and consistent. All healthcare professionals must be educated in spotting and reporting all suspected adverse drug reactions.
