Final answer:
When monitoring a patient who has been taking finasteride for BPH, the clinician should assess for side effects including erectile dysfunction, gynecomastia, and depression. These side effects are associated with finasteride use and can persist as long as the drug is taken.
Step-by-step explanation:
The patient with benign prostatic hyperplasia (BPH) has been taking finasteride (Proscar) for 6 months. In assessing the patient for side effects of this medication, the side effects that should be monitored for include: erectile dysfunction, gynecomastia, and depression. Finasteride is known to be effective for BPH by improving urinary symptoms, but side effects such as sexual dysfunction and mood changes can occur and persist as long as the drug is taken. Erectile dysfunction is a common side effect, while finasteride is not known to cause glaucoma, hypotension, or headaches in the context of BPH treatment.
