Case

Mr. J.S., a 65-year-old male, has been diagnosed with benign prostatic hyperplasia (BPH). He presents to your pharmacy with a new prescription for finasteride 5 mg once daily. (Symptoms of BPH: difficulty urinating, including weak stream and frequent nighttime urination (nocturia)). He is concerned about how long it will take for the medication to work and potential side effects. His current medications include atorvastatin and ramipril for high cholesterol and hypertension, respectively.

Question 1
What is the most appropriate counseling point for Mr. J.S. regarding the onset of action of finasteride for BPH?

A) Symptom improvement can be expected within 1 week.
B) Symptom improvement may take at least 6 months.
C) Finasteride will completely resolve his symptoms within 1 month.
D) Symptom improvement may take up to 3 days.
E) Finasteride will only improve symptoms if combined with an alpha-blocker.

Correct Answer: B) Symptom improvement may take at least 6 months.
Explanation: Finasteride, a 5-alpha reductase inhibitor, works by reducing dihydrotestosterone (DHT) levels, which decreases prostate size. However, this process is gradual, and significant symptom improvement may take at least 6 months of continuous use.

Follow-Up Question 2
After 3 months, Mr. J.S. returns and reports some improvement but still experiences nocturia and a weak stream. What would be the best course of action?

A) Discontinue finasteride and switch to an over-the-counter remedy.
B) Suggest adding an alpha-blocker, such as tamsulosin, to his therapy.
C) Increase the dose of finasteride.
D) Discontinue finasteride and re-evaluate after 1 month.
E) Recommend a referral to a urologist immediately.

Correct Answer: B) Suggest adding an alpha-blocker, such as tamsulosin, to his therapy.
Explanation: Alpha-blockers, such as tamsulosin, provide quicker relief of urinary symptoms by relaxing smooth muscle in the prostate and bladder neck. This can complement finasteride, which primarily reduces prostate size over a longer period.

Follow-Up Question 3
Which of the following is a possible side effect of finasteride that Mr. J.S. should be aware of?

A) Weight gain
B) Erectile dysfunction
C) Increased libido
D) Hypotension
E) Constipation

Correct Answer: B) Erectile dysfunction
Explanation: Finasteride may cause sexual side effects, including decreased libido, erectile dysfunction, and reduced ejaculate volume. These side effects are related to the drug’s impact on lowering DHT levels.

Follow-Up Question 4
Mr. J.S. mentions that his blood pressure has been slightly elevated during recent doctor visits. Which of the following medications could be added to his therapy to help manage both his benign prostatic hyperplasia (BPH) and hypertension?

A) Amlodipine
B) Tamsulosin
C) Doxazosin
D) Furosemide
E) Metoprolol

Correct Answer: C) Doxazosin
Explanation: Doxazosin is an alpha-1 blocker that can be used to treat both BPH and hypertension. It relaxes the smooth muscle in the bladder neck and prostate to improve urine flow, while also lowering blood pressure by dilating blood vessels. This makes it a good option for patients with both conditions.
