At the outset, it should be noted that the drugs mentioned in the question: Torecan (thiethylperazine) and Dulsevia (duloxetine) are subject to 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.

When using these drugs at the same time, you may feel excessive sedation, drowsiness, dizziness, difficulty concentrating, thinking, judging the situation, and making intended movements. If these reactions worsen or if you experience any other disturbing symptoms - please contact your doctor.
