Increased risk of prolong QT interval Click to Show/Hide Mechanism Graph
Drug Name		Telithromycin				Triclabendazole
Mechanism		Prolong QT interval				Prolong QT interval
Key Mechanism Factor 1
		Factor Name		QT interval
		Factor Description		Long QT syndrome is a heart signaling disorder that can cause a fast, chaotic heartbeat (arrhythmia). Many people may not exhibit symptoms, and usually the condition is detected during routine medical tests. In others, the most common symptoms include: sudden fainting, palpitations, dizziness, seizures, sudden death.
Mechanism Description		Increased risk of prolong QT interval by the combination of Telithromycin and Triclabendazole

Recommended Action
Management		Although the risk of a serious interaction is probably low, caution is recommended if telithromycin is used in combination with other drugs that can prolong the QT interval. Since the magnitude of QTc prolongation may increase with increasing plasma concentrations of telithromycin, the recommended dosage should not be exceeded, particularly in patients with renal or hepatic impairment. Patients should be advised to seek prompt medical attention if they experience symptoms that could indicate the occurrence of torsade de pointes such as dizziness, lightheadedness, fainting, palpitation, irregular heart rhythm, shortness of breath, or syncope.
