Saw palmetto: Practice Points – Patient Counselling. FAQ

2010

• Substantial scientific evidence has shown that saw palmetto is an effective treatment for stages 1 and 2 of BPH in cases where the diagnosis of cancer is negative. It is as effective as finasteride and alpha-adrenoreceptor antagonist drugs such as tamsulosin and alfuzosin, although prazosin may be slightly more effective.

• Typically, symptom reduction is experienced within 1-2 months’ treatment, which is well tolerated, and associated with fewer side effects than finasteride and tamsulosin.

• The herb does not affect PSA levels therefore PSA test results will be unaffected.

• If symptoms worsen, blood is detected in the urine or acute urinary retention occurs, seek professional advice.
