Objectives: In 2010, tamsulosin 0.2 mg (OD) was withdrawn from Thailand and replaced with tamsulosin 0.4 mg (OD). Therefore, we assessed the impact of this change on the patients, at a men¡¯s health clinic, with lower urinary tract symptoms suggestive of benign prostatic hyperplasia (LUTS/BPH). Material and Methods: Subjects were 100 men with BPH who had been taking tamsulosin 0.2 mg as needed for at least 3 months. The outcome measures were IPSS, AMS and IEFF5 scores and uroflowmetry. Tolerability was evaluated on by adverse events. Changes from baseline were assessed using the paired t-test. SPSS version 12.0 was used for statistical analysis, with p < 0.05 considered significant. Results: The mean follow up of tamsulosin 0.2 and 0.4 mg were 20.23 and 10.56 months respectively. On switching from tamsulosin 0.2 to 0.4 mg, mean IPSS score improved from 15.54 ¡À SD 1.25 to 14.13 ¡À SD 1.09 (p = 0.034), Q max 15.91 cm3/sec ¡À SD 1.36 to 16.69 cm3/sec ¡À SD 1.52 (p = 0.128), and nocturia 3.15 ¡À SD 0.32 to 2.68 ¡À SD 0.39 (p = 0.015), respectively. However IEFF-5 score and AMS score increased from14.78 ¡À SD 1.38 to 15.79
