Lindane for Lice
Lindane is a prescription shampoo to treat lice. It can cause serious side effects if you do not use it exactly as directed.
Apply the shampoo to dry hair. Do not use any hair conditioner. Leave the shampoo on for 4 minutes. Next, work it into a lather with a small amount of water. And then rinse it out well.
How It Works
Lindane kills lice but does not kill lice eggs (nits).
Why It Is Used
Lindane is sometimes used when other products fail to get rid of lice or when a person can't use any of the other products.
Lindane should not be used by women who are pregnant or breast-feeding, small children, people who have seizure disorders, or people who have certain skin diseases that may increase the likelihood that the product will be absorbed into their skin.
How Well It Works
Lindane can be effective at treating head and pubic lice.
In some places, lice have become resistant to lindane. So lindane may not work as well as other treatments for lice.
All medicines have side effects. But many people don't feel the side effects, or they are able to deal with them. Ask your pharmacist about the side effects of each medicine you take. Side effects are also listed in the information that comes with your medicine.
Here are some important things to think about:
Call your doctor right away if you or your child has:
Lindane can cause serious nervous system side effects if you do not use it exactly as directed.

What To Think About
Lindane is a poison. It can cause harm if it's swallowed or absorbed into the skin. Do not use more of it, do not use it more often, and do not use it for a longer time than your doctor tells you to. Keep it away from the eyes and mouth.
If you have a seizure disorder or if you have certain skin conditions, do not use lindane.
The U.S. Food and Drug Administration (FDA) advises that this product be used exactly as labeled. Although most of the side effects reported from this product are from misuse and overuse, it does contain potentially harmful toxins.
Itching may last for 7 to 10 days after treatment. But itching is not a reason to use the product again. Overuse of lice products (such as using the product more often than it was prescribed) can irritate the skin and may increase the risk of side effects.
Medicine is one of the many tools your doctor has to treat a health problem. Taking medicine as your doctor suggests will improve your health and may prevent future problems. If you don't take your medicines properly, you may be putting your health (and perhaps your life) at risk.
There are many reasons why people have trouble taking their medicine. But in most cases, there is something you can do. For suggestions on how to work around common problems, see the topic Taking Medicines as Prescribed.
Advice for women
If you are pregnant, breast-feeding, or planning to get pregnant, do not use any medicines unless your doctor tells you to. Some medicines can harm your baby. This includes prescription and over-the-counter medicines, vitamins, herbs, and supplements. And make sure that all your doctors know that you are pregnant, breast-feeding, or planning to get pregnant.
Follow-up care is a key part of your treatment and safety. Be sure to make and go to all appointments, and call your doctor if you are having problems. It's also a good idea to know your test results and keep a list of the medicines you take.
