Chlamydia in men is easy to treat and is a common and frequent disease. Men who have a thin discharge from the urethra, a history of impure intercourse, and a crusty film sealing the urethra when they wake up in the morning are considered to have chlamydia as a result of infection. It is easy to confirm the diagnosis by taking the urethral discharge for examination. After the diagnosis is confirmed, standardized medication should be given. Medications such as azithromycin, roxithromycin, doxycycline and clarithromycin are recommended and can be taken orally or given intravenously. The most common is azithromycin 0.5g orally for 7-10 days, and most of them will be completely cured. During the treatment period, do not drink alcohol, do not eat spicy and stimulating food, drink more water, urinate regularly and pay attention to personal hygiene.
