Information for healthcare professionals from market surveillance of medicinal products

Pharmacovigilance in the spotlight

Learning from adverse reaction reports – cases from pharmacovigilance
The purpose of this new section is to use real-life case reports from Switzerland as a reminder of possible side effects that professionals should be aware of in day-to-day clinical practice. The only way to protect patients against undesirable effects is to take account of and report medicinal product risks.
