How can I get rid of pubic lice?
Here's what you need to do to get rid of pubic lice:
Should my boyfriend get treated for pubic lice too?
- Use medicated shampoo to kill the lice on the hair in the affected area. Don't use the shampoo on your eyelashes, though! You can buy the special shampoo at the drugstore. Usually, you only use the shampoo once, but you should always follow the directions on the package carefully.
- Shampoo alone won't get rid of all the lice. Lice eggs are clingy and remain stuck to the pubic hairs. So you have to comb through the hair with a special comb to remove each of the lice eggs. This will prevent the eggs from hatching and turning into more lice that will lay more eggs. The combs are usually included in the packages of medicated shampoo. If not, you can buy them separately at the drugstore.
- If you have lice on your eyelashes, you will need to put a special prescription ointment on them twice a day for 10 days. You can get a prescription for this ointment from your health professional. Do not use lice shampoo anywhere near your eyes, because it can cause blindness.
- Machine-wash and machine-dry your bed linens and clothing to kill any lice that may be living in them. Luckily, you don't need to wash every piece of clothing you own. Pubic lice can't survive away from human beings for very long. Clothes that haven't been in contact with your body for more than 72 hours will not have any living lice. back to top
