Summarize this article in one sentence.
Using too much Vagisil can lead to severe side effects, so only apply a small amount. The amount of Vagisil cream that you use should be about as long as your fingertip (about one inch long). Do not insert Vagisil into your vagina. Only use it on the parts of your vagina that are outside of your body, such as your labia and vulva. Use your finger to rub the cream into the outer areas of your vagina to help soothe itching. Do not apply Vagisil to large areas of your body. Applying Vagisil to large areas of your body may cause severe side effects, so only use it on the affected areas of your vagina. If your itching extends beyond the area that a small amount of Vagisil will cover, then call your doctor or gynecologist. The product works by blocking the nerve signals that cause itching. This will provide some temporary relief from vaginal itching. Just keep in mind that it might take a few minutes for the medicine to work, so try to be patient. You should not use Vagisil more than four times per day. If you still have symptoms after using Vagisil, then contact your doctor or gynecologist.  You may require a prescription strength medication.
Use the smallest amount needed. Apply Vagisil to the outside of your vagina only. Allow your skin to absorb the Vagisil cream. Reapply three to four times per day.
