M2 Logo Risk of infections with Prolia (denosumab) 


16 May 2019

Monitoring finishes 30 November 2019.

Medsafe is highlighting a possible risk of infections with the use of Prolia (denosumab). To help Medsafe assess whether any additional action is warranted, Medsafe is encouraging prescribers or patients to report any adverse events related to this medicine, particularly any infections. At this stage Medsafe is still considering the significance of this potential safety signal.

This communication was triggered by a report received by the Centre for Adverse Reactions Monitoring (CARM). The report (CARM ID number 131099) describes a 68-year-old female patient who developed severe pneumonia after receiving denosumab.

Various types of infections have been suggested to be potentially associated with Prolia in the scientific literature. Medsafe is therefore encouraging reports of all types of infections to investigate this risk further.

Additional Information

Denosumab is a biologic RANKL inhibitor used to treat osteoporosis in men and postmenopausal women. Prolia is currently the only approved denosumab product for this indication.

The New Zealand data sheet includes warnings on the risk of skin infections, such as cellulitis [1]. Other infections, such as pneumonia, are not stated in the data sheet.

It has been proposed that RANKL inhibition may have immune modulating effects and this may increase the risk of infections. However, clinical trials and observational studies have not conclusively shown that there is a significant risk of severe infections associated with Prolia.

The overall benefit-risk balance of Prolia remains positive. Advice on the known side effects of Prolia can be found in the consumer medicines information (CMI) and data sheets.
