"absolute life changer. i&#039;m in my late 30&#039;s and have been on antibiotics for most of my life to treat moderate to severe acne. besides accutane, i found the most success with bactrim, but recently became unable to tolerate it. it took four months for me to see results from spironolactone, but what a relief to now not have my life revolve around trying unsuccessfully to manage breakouts and cysts anymore! i did experience lightheadedness in the beginning and still on occasion. cut from 100mg to 50mg in the beginning to help the dizziness, and now back to 100mg. very thankful i found this med."
