Hi, Solitral (also known as Tamsulosin) is a medication commonly prescribed to improve urinary symptoms in men with an enlarged prostate gland. It works by relaxing the muscles in the prostate and bladder, making it easier to urinate. The duration of treatment with Solitral can vary depending on the individual and their specific medical condition. Typically, Solitral is taken for several weeks or months, and in some cases, it may be taken for longer periods of time. However, it s important to note that Solitral is not a cure for urinary symptoms and may only provide temporary relief. If you have been taking Solitral for a year and are still experiencing frequent urination at night, it s important to speak with your doctor. They may want to re-evaluate your condition and consider other treatment options, such as medication or surgery. Additionally, lifestyle changes such as reducing caffeine and alcohol intake, and practicing pelvic floor exercises, may also help improve your urinary symptoms. Take care.
