My doctor gave me metronidazole .075% gel to put on my skin four times a day. My psoriasis was completely gone overnight. This gel is typically used as a vaginal cream for bacterial and yeast infections. It’s available by prescription only.
Editor’s note: Metronidazole is an antibacterial treatment that comes in several forms. The most common form is a low-potency suppository cream used to treat vaginal infections. A stronger, topical skin cream is available by prescription.
