Report an Adverse Event

中文Deutsch | English | Español | Français | 한국어 | Português

If you have experienced a potential side effect on a BeiGene product, report them here.

When a patient experiences something unexpected, harmful or negative while taking a medicine, this is called a side effect (also sometimes referred to as an Adverse Event).

An adverse event (AE) is any untoward medical occurrence in a patient or clinical trial subject administered a medicinal product and which does not necessarily have a causal relationship with this treatment.

An adverse event (AE) can therefore be any unfavorable and unintended sign, symptom or disease temporarily associated with the use of a medicinal product (e.g., BeiGene study drug, or marketed medicinal product distributed by BeiGene), whether or not considered related to the medicinal product.

Examples of potential side effects/adverse events include:

  • Headache
  • Nausea (feeling sick)
  • Vomiting

Even if you don’t know what caused the potential side effect or if you suspect that it was not caused by the medicine, the potential side effect still needs to be reported.
