The symptoms of frequent urination at night in men may be caused by prostatitis, prostate enlargement, or overactive bladder disorder. The actual diagnosis needs to be made in the urology department of a regular hospital, through routine prostate fluid, ultrasound examination of the prostate and urodynamic examination of the bladder. If the problem is inflammation of the prostate or prostatic hyperplasia, you can take oral tamsulosin capsules, doxazosin tablets, together with Chinese medicines that clear heat and dampness and promote diuresis, such as prostate Antong tablets and retention tablets for 2-4 weeks to get effective relief from the symptoms. If prostate problems are ruled out, it is considered to be caused by overactive bladder. You can take oral medications to stabilize bladder function at night before bedtime, such as tolterodine tablets and flavonol permethrin hydrochloride tablets for 1-2 months, and the symptoms of frequent urination at night will be relieved.
