Summary
Triptorelin, a GnRH agonist used for androgen deprivation, can prolong the QT interval and lithium can also affect cardiac conduction. Combined use may increase arrhythmia risk, especially with electrolyte abnormalities or cardiac disease.
What this interaction means in plain words
Lithium and Triptorelin can affect each other. The combination is often manageable, but it may need a change of dose, a change of timing, or extra checks while both are taken.
Lithium belongs to Central Nervous System; Triptorelin belongs to Endocrine.
Why it happens
Additive effects on QT interval; the androgen deprivation effect of triptorelin and the direct effect of lithium on repolarization.
What to do
Perform a baseline ECG and monitor periodically, correcting potassium and magnesium abnormalities. Avoid adding further QT-prolonging drugs.
What to ask your pharmacist
- Should I take them at different times of day?
- Does the dose of either medicine need to change?
- Is there anything I should avoid, such as alcohol or certain foods, while on both?
