At the outset, it should be noted that the drugs mentioned in the question: Trittico (trazodone) and Torecan (thiethylperazine) are prescription, so the legitimacy and need to combine them in therapy should be determined by a doctor. This combination of drugs can be used, but you should strictly follow your doctor's instructions and observe your body's reactions.

It is recommended to keep at least a few hours between taking Trittico and Torecan, preferably 6-8 hours. Trittico (trazodone) can increase the sedative effect of other drugs, including Torecan, which increases the risk of side effects such as drowsiness or dizziness. Therefore, it is important to monitor your well-being and consult your doctor if you have any doubts or experience unwanted symptoms.
