Erythrocin Erythromycin Terlipressin Acetate
MajorExtreme caution is needed if terlipressin is used with other medicines that can prolong the QT interval, meaning they change the heart's rhythm. These include class IA and class III antiarrhythmics, erythromycin, certain antihistamines and tricyclic antidepressants. The same caution applies to medicines that may cause hypokalaemia (low potassium) or hypomagnesemia (low magnesium).
These medicines can affect each other in a serious way. Do not start taking them together unless your doctor has said it is OK. If you already take both, do not stop either one on your own: speak to your doctor or pharmacist soon.
