75% alcohol has anti-bacterial and anti-inflammatory effects on some germs and bacteria, but pubic lice are parasites outside the human body, so the simple use of alcohol generally can not completely kill pubic lice, and need to be under the guidance of a professional doctor, with the medication for treatment. After suffering from pubic lice, patients need to apply the appropriate drugs to the affected area to achieve the purpose of killing lice and eggs, commonly used drugs are tincture of bacitracin, benzyl benzoate, permethrin, pyrethrin, etc. In addition, patients can also take ivermectin for treatment. Due to the fact that pubic lice are often parasitized in the pubic hair and follicle holes of male and female vulva, their reproduction ability is very strong, and they can be infected through sexually transmitted infections or indirect contact, such as pubic lice, lice eggs contaminate clothes and toilet bowls along with the shedding of pubic hairs, and other people will be infected by contacting the items contaminated by pubic lice. Therefore, pubic lice infected people should also remove the pubic hair and burn to prevent the spread of pubic lice, their underwear should be strictly boiled and washed or ironed, and the patient’s other clothes and bedding should be sterilized in boiling water. If the patient’s sexual partner is suffering from the same disease, the patient should receive treatment together. During the treatment period, patients can have a normal diet, but should avoid eating greasy and cold foods, such as fried chicken and ice cream, to avoid discomfort. Meanwhile, sexual intercourse is prohibited to avoid cross-infection.
