We treat all your “personal data” in accordance with local data protection rule. Any personal data provided here related to adverse events or other activities related to pharmacovigilance will be used solely for these purposes. Read our notice of personal data processing

A side effect (also known as adverse reaction) is a harmful and unintended response to a pharmaceutical product. This includes any undesirable patient effect suspected to be associated with pharmaceutical product use. An unintended effect, pharmaceutical product abuse, overdose, interaction (including drug-drug and drug-food interactions) and unusual lack of therapeutic efficacy are also considered reportable side effects.

Although our products are tested extensively in clinical trials before they are authorized, not everything is known about their side effects until they have been used by many people over time. Novo Nordisk routinely monitors the safety of all our products. By reporting complaints and side effects, you are giving us important feedback which will ultimately help us take appropriate actions and to provide better instructions for how to use our products.
