DEAR DR. ROACH: I have an enlarged prostate. My urologist has recommended that I take 5 mg of finasteride daily for this. Im hesitant to take this medication because of potential side effects, particularly the sexual side effects that can go along with it. What is your opinion of this medication? Also, my urologist says that Flomax would not be appropriate for me since my blood pressure is on the low side. Taking Flomax with low blood pressure evidently would cause me to feel tired much of the time, according to him. Do you agree with that? R.K.
ANSWER: Men have more than one treatment choice for medicine to treat enlarged prostate. Finasteride (Propecia and Proscar) blocks formation of a type of testosterone responsible for both enlarged prostate and hair loss. Doxazosin (Flomax) relaxes smooth muscle in the prostate. Both are reasonable choices for men with symptoms.
