Is it fave for me to take trepiline while taking lily fluoxetine? both were prescribed by the same doctor but my research says they do interact majorly

Med combination: Mixing amitriptyline and fluoxetine may increase risk for sedation, dry mouth, blurred vision, constipation, & urinary retention per Drugs.Com drug interaction checker. However, I suspect that your physician prescribed only low dose amitriptyline to allow you to sleep. This is not an unusual drug combination. Even though there is a risk, most tolerate this well.
