Can I take Quetiamine and Sertraline together?

Why this happens

Both drugs can affect the electrical activity of the heart (the QT interval). When combined, this effect can be additive. Furthermore, both drugs influence serotonin levels; sertraline increases serotonin, and quetiapine can also affect serotonin receptors, potentially leading to an over-accumulation. Both drugs also have sedative properties that add together.

What you should do

You should speak to your doctor before taking these together. They may want to perform a simple heart trace (ECG) to check your heart rhythm. Seek medical help immediately if you feel dizzy, faint, or experience a fast or pounding heartbeat. Also, watch out for signs of serotonin syndrome, such as shivering, sweating, confusion, or muscle stiffness. Avoid driving or using heavy machinery until you know how this combination affects your alertness.
