Q: Why does Duloxetine sometimes cause dry mouth?

Q: Is Duloxetine considered a strong antidepressant?
Duloxetine is classified pharmacologically as a Serotonin-Norepinephrine Reuptake Inhibitor (SNRI). The official mechanism of action describes it as a potent dual inhibitor, meaning it blocks the reuptake of both serotonin and norepinephrine neurotransmitters.

Antidepressants, including this medicine, are generally not considered addictive but can cause physiological dependence. This means the body adapts to the drug. The dosage must be gradually reduced under professional supervision when the medicine is stopped.
Q: Is there a difference in effect if Duloxetine is taken in the morning or evening?
