Drinking plenty of water each day can help prevent urethritis. Women who have symptoms that occur within 24 hours of sexual intercourse should always urinate immediately after having intercourse. Taking a small dose of antibiotics after intercourse also decreases episodes of urethritis and cystitis.
Good hygiene for yourself and any sexual partners is important. Safer sex behaviors can decrease the risk of developing sexually transmitted diseases, which can cause urethritis.
Getting treatment as soon as symptoms appear is important in preventing damage to the urethra.
