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 Inotuzumab ozogamicin and Macimorelin

Recommended Action
Management		Coadministration of macimorelin with other drugs that can prolong the QT interval should generally be avoided. A sufficient washout period following discontinuation of these drugs is recommended prior to macimorelin administration. Patients treated with any medication that can cause QT prolongation 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.
