STD Information: Allergic Vaginitis
Sometimes referred to as 'chemical vaginitis,' this condition is a great mimicker. Because it often affects not only the vagina itself but external tissues (the vulva), it is often mistaken for a yeast infection, or even new onset genital herpes. It's due to genital contact with an irritant, the most common offending agents being latex or components of spermicides, lubricants, a new detergent/soap/bath gel, silicone sex toys, or 'feminine' deodorants. Anything that can cause an allergic skin reaction (like a rash) can cause a similar reaction on mucous membranes, including genital tissues.
- Symptoms: red, painful or irritated or itching vulva; increased vaginal discharge. The vulva may have whitish or grayish striations or hue, along with some scaly skin.
- Treatment: if you can figure out the offending substance, discontinue use. Antihistamines (Benadryl for example) may help relieve symptoms. Low-dose (0.5%) cortisone cream is also effective, but consult your health care provider before applying any steroid cream to the genital area.
