Symptoms

Pubic lice can be uncomfortable, but rarely pose a serious health risk. Their bites usually leave small bluish marks on the skin. Those with pubic lice will experience itching which often worsens at night. Some individuals may develop a severe allergic reaction to the bites.

Treatment

The treatment consists of the application to the affected areas of pediculicide (treatment against lice), which are available in pharmacies without prescription. It is important to follow the pharmacist's directions and recommendations.

In addition to the treatment, it is important to wash clothing and bedding in very hot water or to have them dry cleaned. Objects that are difficult to wash can be placed in hermetically sealed bags for a minimum of 2 weeks. A thorough vacuuming of the house is also recommended.
