Hello, i was diagnosed with chlamydia and prescribed the one dose of azithromycin four tabs. i took them four days ago and still have slight irritati?

Not only chlamydia?: Chlamydia usually causes no symptoms in women. Sometimes vaginal discharge and/or painful urination, but usually not "irritation", itching, genital swelling, redness, etc. You might have had more than chlamydia, such as a yeast infection. Or possibly herpes if any blisters or sores. Check back with the doctor or clinic where you were treated. Good luck!
