Adults may experience mental health changes as well, including worsening of depression, thoughts of suicide or self-harm, anxiety, agitation, panic attacks, insomnia, aggression, irritability, impulsivity, restlessness, and abnormal states of excitement. You should watch for these symptoms most carefully when you start using fluoxetine HCL and when your dose has just been changed.
