If your vaginal dryness is a problem during intercourse, using lubricants can help temporarily alleviate the problem.  Lubricants can be purchased online, in pharmacies, and can also be bought at sex shops. Lubricated condoms can also be purchased to alleviate vaginal dryness during intercourse.  Lubricants should be applied directly to the vagina shortly before intercourse. Lubricants only temporary relief, so if you're looking for a long term cure you might want to look elsewhere. Vaginal moisturizers are topical creams applied directly to the vagina. Most non-hormonal vaginal creams can be purchased over the counter.  Vaginal creams can be found at the supermarket or drug stores. Replens, Luvena, K-Y Silk-E Vaginal Moisturizer and KY Liquibeads Vaginal Moisturizer are examples of over the counter vaginal creams.  Talk to your gynecologist before using any new products. While most are safe for use, some may increase the risk of infection and adverse reactions, such as rashes or sores. Estrogen creams are topical ointments applied directly to the vagina that contain a low dose of the hormone estrogen. You must have a prescription to obtain estrogen cream.  Usually around bedtime, estrogen cream is inserted directly into the vagina with an applicator or a clean finger. Depending on your medical history, your doctor will tell you how often to use estrogen cream and in what amount.
