Can phentermine make you angry?

Anger difficulties are one of the most regularly reported side effects of phentermine, with more than 1 in 5 patients expressing dysphoria at some point during therapy. "Phen wrath" is the colloquial term for this seemingly irrepressible, sometimes unreasonable anger and dissatisfaction.

Phen wrath is a word that expresses the annoyance, impatience, hostility, irritability, and anger that people experience while using phentermine. Angry outbursts, yelling, and even physical destruction or violence are common manifestations of this fury.

Talk to your doctor if you or your loved ones have noticed that you are suddenly overreacting to situations or are frequently in a poor mood since starting phentermine.
