Lindane is an organochlorine insecticide that has been in use for over 50 years. It is the active ingredient in a shampoo that treats lice and scabies, used as a second line treatment.

However, lindane is also known to be a neurotoxin that can affect the liver and kidneys. Other side effects range from skin irritation and dizziness to seizures and even death.

The EPA (Environmental Protection Agency) banned its use in agriculture in 2006 but that has had no bearing on the pharmaceutical use of lindane, which is governed by the FDA (U.S. Food and Drug Administration).

Congressman Ed Makey, a Massachusetts democrat, wrote a letter May 31, 2012 to the FDA asking them to halt the use of lindane in shampoos that are used to treat head lice on children. He pointed out that children are more susceptible to the effects, especially if parents become overly zealous in their attempts to eradicate the lice or scabies.

The American Academy of Pediatrics recommends 1 percent permethrin lotion as an initial treatment for most head lice infestations with a second application 7‑10 days after the first.

The CDC (Center for Disease Control and Prevention) and the FDA recommend other formulations containing pyrethrins, prescription malathion or benzyl alcohol lotions as first line treatment for lice. These chemicals also have their own risk of use.

Alternately, there are other products on the market that can be tried to remove lice such as mechanical removal with a nit comb, cetaphil dried with a hair dryer, and various other nontoxic agents, as a way to smother the lice. These techniques only have varying levels of success.

Makey’s letter also pointed out that lice and scabies have become increasing resistant to lindane due to widespread use. “Studies of lindane show that it only kills 50-70% of lice eggs”.

More than 160 countries have banned the use of lindane due to concerns of neurotoxic dangers. California banned the use of lindane in pharmaceutical use 10 years ago due to water contamination concerns and its potential effects on children.
