Lindane cream for pubic lice should be rubbed for about 1 week. Lindane cream works by directly contacting the body surface of the lice, entering the blood and tissue fluids through the blood vessel walls, thus paralyzing the nervous system of the lice and causing them to die. Generally, the breeding period of pubic lice is 3~5 days, so Lindane cream should be used for about 1 week to ensure the complete elimination of pubic lice and its effectiveness. If the lice are not cured after 1 week of application, a second treatment can be carried out. Localized irritation and occasional dizziness may occur with the use of Lindane Cream, but these symptoms are usually mild and will subside after 1-2 days. Prolonged use of the drug, absorbed through the skin, can damage the central nervous system and lead to neurological symptoms such as epilepsy, and in a few patients, allergies and hives may occur. Lindane Cream is recommended to be used under medical supervision, if you feel unwell, such as allergic symptoms or central nervous system symptoms, it is recommended to stop the medication immediately, and go to the hospital in time to give targeted treatment or therapy.
