A patient diagnosed with depression is prescribed fluoxetine (Prozac). Which of the following would the healthcare provider most likely observe if the patient experiences an adverse effect of this medication?

Fluoxetine increases the synaptic concentration of serotonin the central nervous system, but may have effects on other nervous system functions. Although the mechanism has not been completely elucidated, sexual dysfunction is one of the most common adverse effects of SSRIs in both men and women. Other side effects include insomnia, cold symptoms (stuffy nose, sneezing, sore throat), and GI symptoms (dry mouth, nausea, upset stomach, constipation).
