 |
Current Treatment OptionsTreating head lice today with what's currently availableTreating head lice can seem like a complicated process when patients and families are faced with a diagnosis. For instance, combing through hair can be tedious; some products require multiple treatments, while others must remain in contact with the hair for long periods of time (8-12 hours).5,19When it comes to safety, some substances that are found in prescription and over-the-counter products may prove harmful if not used according to the directions on their labeling.2 It is important to consult with a healthcare professional prior to selecting a treatment.2 Find out why here. Treating an infestation may require two steps1. Topical Therapy (Shampoos, Conditioners, and Lotions)What are they?Topical agents include shampoos, creams, lotions and conditioners that contain substances that kill lice and nits. Some topical products that have been approved for the treatment of head lice are derived from the following 3 insecticidal groups: organochlorines, organophosphates, pyrethroids.5 How are they applied? Shampoos are usually applied to damp or dry hair and then rinsed out thoroughly. Shampoos containing Pyrethrin and some conditioners made of Permethrin are available over-the-counter.1,5 Some topical therapies are available by prescription, such as those containing malathion, benzyl alcohol, and lindane.5,19,20 A few of the drawbacks It is important to note that the substances used in some topical agents may produce an itching or burning effect. If this is persistent, an additional topical medication may be required just to relieve the symptoms. Lice have also become resistant to a number of topical treatments.1,5 Learn more about these products here. 2. Mechanical RemovalWhat is it?Lice and nit combs are fine-tooth combs with stiff teeth and narrow slots. They may vary in length and be made of plastic or metal. How does it work? Combing is recommended as a second step to locate and remove eggs and nits that are left over after topical solutions are applied. Some evidence suggests that combing can damage lice, making them less likely to survive.1,5 Why it's not always effective Combing can take hours, and can be tedious. If combing is not done thoroughly or correctly, lice and eggs may still be present after treatment.1 Non-approved treatments & Home RemediesHome remediesThere is no evidence that petrolatum, mayonnaise, margarine, etc. suffocate lice as is commonly believed. They can be inconvenient, messy and do not have any pediculicidal effect.18 DANGER Flammable or toxic substances, such as gasoline or kerosene should never be used.5 |
