Summary
Both are GnRH-axis agents used for androgen deprivation, and androgen deprivation can prolong the QT interval. Using them together provides no therapeutic benefit and adds no clear advantage, while QT risk is theoretically additive.
What this interaction means in plain words
Degarelix and Leuprolide have a small, usually unimportant interaction. Most people can take both; the pharmacist may still mention it so that any unexpected effect is recognised.
Degarelix belongs to Endocrine; Leuprolide belongs to Endocrine.
Why it happens
Both agents lower testosterone, which is associated with QT prolongation; the effect is additive in theory, and the combination is pharmacologically redundant.
What to do
Avoid combining two GnRH-axis agents, as it is duplicate therapy. If one is switched to the other, obtain a baseline ECG and correct potassium and magnesium.
What to ask your pharmacist
- Is there anything I should notice while taking both?
- Do I need to tell my doctor at the next visit?
