Lifestyle
Lifestyle alterations to address the symptoms of BPH include physical activity, decreasing fluid intake before bedtime, moderating the consumption of alcohol and caffeine-containing products and following a timed voiding schedule. Patients can also attempt to avoid products and medications with anticholinergic properties that may exacerbate urinary retention symptoms of BPH, including antihistamines, decongestants, opioids, and tricyclic antidepressants; however, changes in medications should be done with input from a medical professional. Physical activity
Physical activity has been recommended as a treatment for urinary tract symptoms. A 2019 Cochrane review of six studies involving 652 men assessing the effects of physical activity alone, physical activity as a part of a self-management program, among others. However, the quality of evidence was very low and therefore it remains uncertain whether physical activity is helpful in men experiencing urinary symptoms caused by benign prostatic hyperplasia. Voiding position
Voiding position when urinating may influence urodynamic parameters (urinary flow rate, voiding time, and post-void residual volume). A meta-analysis found no differences between the standing and sitting positions for healthy males, but that, for elderly males with lower urinary tract symptoms, voiding in the sitting position-- 
decreased the post void residual volume;
increased the maximum urinary flow, comparable with pharmacological intervention; and
decreased the voiding time.This urodynamic profile is associated with a lower risk of urologic complications, such as cystitis and bladder stones. Medications
The two main medication classes for BPH management are alpha blockers and 5α-reductase inhibitors. Alpha blockers
Selective α1-blockers are the most common choice for initial therapy. They include alfuzosin, doxazosin, silodosin, tamsulosin, terazosin, and naftopidil.
They have a small to moderate benefit at improving symptoms. Selective alpha-1 blockers are similar in effectiveness but have slightly different side effect profiles. Alpha blockers relax smooth muscle in the prostate and the bladder neck, thus decreasing the blockage of urine flow. Common side effects of alpha blockers include orthostatic hypotension (a head rush or dizzy spell when standing up or stretching), ejaculation changes, erectile dysfunction, headaches, nasal congestion, and weakness. For men with LUTS due to an enlarged prostate, the effects of naftopidil, tamsulosin and silodosin on urinary symptoms and quality of life may be similar. Naftopidil and tamsulosin may have similar levels of unwanted sexual side effects but fewer unwanted side effects than silodosin.Tamsulosin and silodosin are selective α1 receptor blockers that preferentially bind to the α1A receptor in the prostate instead of the α1B receptor in the blood vessels. Less-selective α1 receptor blockers such as terazosin and doxazosin may lower blood pressure. The older, less selective α1-adrenergic blocker prazosin is not a first line choice for either high blood pressure or prostatic hyperplasia; it is a choice for patients who present with both problems at the same time. The older, broadly non-selective alpha blocker medications such as phenoxybenzamine are not recommended for control of BPH. Non-selective alpha blockers such as terazosin and doxazosin may also require slow dose adjustments as they can lower blood pressure and cause syncope (fainting) if the response to the medication is too strong.
