Hi & Welcome.
It is not safe to take these medications together.

Prolonged QT interval on electrocardiogram (ECG) a side effect may occur with the use of either of these prescribed medications.

So, taking Trazodone while on Metronidazole can prolong the QT interval as an additive effect and can increase the risk of ventricular arrhythmias including torsade de pointes which may cause dizziness, light headedeness, fainting, palpitations, irregular heart beats, shortness of breath and sudden death.

You are therefore advised to consult your treating doctor for an alternate effective antidepressant instead of Trazodone.

Hope this will help.
