FDA Approves New Lice Treatment
September 6, 2011 by staff
FDA Approves New Lice Treatment, When children go to school, annual plague of head lice is hidden beyond the classroom doors. The vile creatures spread of the disease, but can be a serious annoyance for teachers and families. The bugs are estimated to affect between 6 and 12 million children in the U.S. each year and parents often resort to a variety of pesticide-based shampoos and treatments for relief.
Parents often are unaware that some of the most prescribed treatments and prescription, can be harmful to children, an investigation found News iWatch. Reports unfavorable Food and Drug Administration event – collected anonymously from doctors, hospitals and others – in particular cases where the pesticide lice treatments have been involved in conditions ranging from headaches to death. The reports were obtained under the Freedom of Information Act.
One of the biggest concerns of some health experts is a prescription treatment for head lice and scabies called lindane. The pesticide has been elimination worldwide since 2009 by the Stockholm Convention, a global treaty that covers some of the deadliest toxins in the world. U.S. has not ratified the treaty, and has no imminent plans for a ban of lindane for head lice.
Since 2006, lindane can no longer be used here in crops or livestock, or for any other purpose regulated by the Environmental Protection Agency. The so-called “second line” treatment – meaning that should only be used if other methods fail – for lice and scabies, lindane has been linked to cancer, seizures and deaths, the FDA said.
“It is not possible to put Lindane dog in the U.S.,” said Joe DiGangi, PhD, a senior scientist and technical advisor of the International POPs Elimination Network, an umbrella organization of groups trying to eliminate some of the most toxic chemicals in the world. “But they’re still letting you get in your child’s head.”
Lindane and represented 10.5 million in U.S. sales in 2010 for head lice and scabies, according to IMS Health, a health information company.
Pesticide called permethrin and Malathion may also be problematic for the treatment of lice. Permethrin is popular in the counter products like Nix. Malathion and lindane in general, require a prescription for drugs that go by the names or Kwell Ovide, respectively.
Nix, along with other products, has been approved for use in children as young as two months old.
Jerry Jabbour, vice president and general counsel at Wockhardt USA, whose subsidiary manufactures lindane, said the U.S. is not bound by the Stockholm Convention, and that many of the most problematic issues with lindane have been linked to agricultural uses and the failure of pesticides to divide naturally in the environment.
“This is a powerful pesticide,” said Jabbour. “Yes, however, when used as … is a good alternative when first-line therapies do not work. Anything you wear on your body or your body has the potential for adverse events to happen. We see that there is demand for a doctor to the product … and we feel like we are offering an alternative. ”
Robyn Ungar, a spokesman for Insight Pharmaceuticals, which makes Nix, said the product has not been directly linked to the problems associated with the pesticide.
“Nix only offers a solution for parents or guardians seeking to treat and remove lice and their eggs in one application and easy to use,” said Ungar. “In addition, the ingredient of pesticide, permethrin is an effective alternative to chemical treatments more severe.”
But health experts are concerned by recent studies showing that the shampoos are less effective than it used to be like the lice are becoming resistant. That can often mean that parents are their children shampoo again and again – a dangerous practice, especially if parents ignore the strict limits of time between treatments. Although many doctors consider safe pesticides at low doses, advocates say that many pediatricians do not recognize the signs if something went wrong.
“The doctors are so ignorant about the impact of these neurotoxins in the people you could have a significant number of responses among children, but nobody really connects the dots,” said Stuart Calwell, a lawyer from West Virginia who has litigated cases in against chemical and pesticide manufacturers. “If weeks and months go by and the child’s behavior begins to change … there is rarely a connection.”
“It’s one things to spray pesticides over broccoli to kill insects, but when he did come close to putting children to kill bugs?” Asked Calwell.
Malathion has been linked to seizures and other health problems. A 2007 study said there is “some relationship” between exposure to pesticides and childhood cancer, while other reports have shown that children are more susceptible to problems with Malathion than adults.
Permethrin, another pesticide often combined with other chemicals in shampoos and over-the-counter and prescription lotions, has neurotoxic properties similar to some experts question whether to apply to a child’s head.
Richard Clapp, an environmental health expert and professor emeritus at Boston University, said that each compound could cause problems. Malathion, a chemical nerve can cause weakness and tingling in the arms and legs as well as seizures, said Clapp. Permethrin, especially when combined with other problematic chemicals, can cause seizures, and future behavioral problems. In a memorandum of 2009, the EPA has classified permethrin as “probably carcinogenic to humans”, under some conditions.
“My kids are older now, but I would say not to put [pesticides] near their children,” said Clapp.
Many pediatricians feel secure compounds at low doses – usually problems arise when they are overused or instructions are not followed. But some health experts say put a pesticide on a child’s head for the treatment of pests that are relatively harmless, is in excess of itself and may cause problems attributed by the road.
