A lice-killing lotion containing 1% permethrin or a mousse containing pyrethrins and piperonyl butoxide can be used to treat pubic (crab) lice. These products are available over-the-counter without a prescription at a local drug store or pharmacy. These medications are safe and effective when used exactly according to the instructions in the package or on the label. Lindane shampoo is a prescription medication that can kill lice and lice eggs.
Trichomoniasis is another type of vaginal infection. It is caused by a single-celled parasite that is usually spread through sex. In addition to causing bleeding after sex, it can also cause vaginal discharge and itching.
Bleeding after sex, also called post-coital bleeding, is a symptom that should not be ignored because it can be a warning sign of several serious conditions. Conditions that can cause bleeding after sex include the following: 1) Precancer (dysplasia) or cancer of the cervix. Most precancers and early cancers do not bleed, but it is very important to rule this out. A Pap smear is recommended, and for women over 30, an HPV test should be done.
