Firmagon Disease Interactions

There are 3 disease interactions with Firmagon (degarelix).

Moderate

Degarelix (applies to Firmagon) hepatic impairment

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Liver Disease

Hepatic impairment can lower degarelix exposure. It is recommended to monitor testosterone concentrations on a monthly basis in patients with hepatic impairment until medical castration is achieved. Degarelix has not been studied in patients with severe hepatic impairment and caution is therefore warranted in this group of patients.

GNRH antagonists (applies to Firmagon) QT prolongation

Moderate Potential Hazard, Moderate plausibility. Applicable conditions: Long QT Syndrome, Congestive Heart Failure, Electrolyte Abnormalities

Androgen deprivation therapy may prolong the QT/QTc interval. Health care providers should consider if benefits of therapy outweigh the potential risks in patients with congenital long QT syndrome, congestive heart failure, electrolyte abnormalities, or taking other drugs that can also prolong the QT interval. Consider periodic monitoring of EKG and electrolytes.
