Can I take Amlodopine and Quetiamine together?

Why this happens

Both amlodipine and quetiapine have the side effect of lowering blood pressure. Amlodipine is designed to do this, but quetiapine can also cause 'orthostatic hypotension' (a drop in blood pressure when standing). When used together, these effects add up. Additionally, quetiapine can occasionally affect the electrical activity of the heart (QT prolongation), and while amlodipine doesn't usually cause this, the combination requires caution.

What you should do

You can take these medicines together, but you should be careful. To prevent dizziness, try to stand up slowly. If you feel very dizzy, faint, or notice a fast or pounding heartbeat, contact your doctor. Your doctor may want to monitor your blood pressure more closely when you first start this combination or if your dose is changed.
