Introduction
Pediculicide; fixed-combination preparation containing pyrethrins (a pediculicide) and piperonyl butoxide (has little or no insecticidal activity but potentiates that of pyrethrins).a
Uses for Pyrethrins with Piperonyl Butoxide
Pediculosis
Topical treatment of pediculosis capitis (head lice infestation).103104107112117120121122123
An alternative rather than a preferred treatment for pediculosis capitis.107108 Permethrin 1% generally considered the treatment of choice, and malathion 0.5% is recommended when permethrin resistance is suspected.103107108113114116117125
Base selection of a pediculicide on efficacy (including both pediculicidal and ovicidal activity), safety, cost, availability, ease of application, age of patient, presence of other scalp infections, patient preference, severity of the infestation, potential for transmission, number of recurrences, and the pattern of resistance in the geographic region.113
Topical treatment of pediculosis pubis (pubic lice infestation).101104112115120121122123 Considered a pediculicide of choice by CDC and others for treatment of pediculosis pubis, including in HIV-infected patients.101104112115
Topical treatment of pediculosis corporis (body lice infestation).103120121122123124125 In some cases, body louse infestations may be treated by improved hygiene and by decontaminating clothes and bedding by washing at temperatures that kill lice.103125 If the infestation is severe, a pediculicide should also be used (e.g., topical permethrin, topical pyrethrins with piperonyl butoxide, topical malathion, oral ivermectin).124125
One of several options recommended for treatment of pediculosis corporis in the adjunctive treatment of epidemic (louse-borne) typhus.103 The causative agent of epidemic typhus (Rickettsia prowazekii) is transmitted person-to-person by Pediculus humanus corporis and thorough delousing (especially among exposed contacts of individuals with typhus) is recommended in epidemic situations.103
Scabies
Not effective for treatment of scabies (mite infestation).a
Pyrethrins with Piperonyl Butoxide Dosage and Administration
General
Measures to Avoid Reinfestation and Transmission
To avoid reinfestation or transmission of pediculosis or scabies, most experts recommend that clothing and bed linen that may have been contaminated by the infested individual during the 2 days prior to treatment should be decontaminated (machine-washed in hot water and dried in a hot dryer, dry-cleaned, or treated with an appropriate pesticide) or removed from body contact for ≥72 hours.103104106113
Although it may not be necessary, items that cannot be laundered or dry-cleaned should be removed from contact and sealed in a plastic bag for 10–14 days.103106116
Combs and brushes used by the infected patient may be disinfected by soaking in hot water (temperature >54°C) for 5–10 minutes;103106 alternatively, they can be soaked in alcohol or a pediculicide for 1 hour.106112
Furniture and floors of rooms inhabited by patients infested with lice should be thoroughly vacuumed.103106116 Fumigation of living areas is not necessary and is not recommended.103106114116
In the treatment of pediculosis capitis (head lice infestation), a fine-toothed comb often is recommended to remove any remaining nits (eggs) or nit shells.103106112113116117118 Some experts do not consider nit removal necessary since only live lice can be transmitted, but recommend it for aesthetic reasons and to decrease diagnostic confusion and unnecessary retreatment.103116117118 Others strongly recommend removal of nits (especially those within 1 cm of the scalp) since no pediculicide is 100% ovicidal and potentially viable nits may remain on the hair after pediculicide treatment.103116117118 Although many schools will not allow children with nits to attend, AAP and other experts consider these no-nit policies excessive.103114116
Administration
Topical Administration
Apply topically, usually as a shampoo containing 0.33% pyrethrins and 4% piperonyl butoxide.120121122123
For external use only.120121122123 Do not administer orally and do not apply to mucous membranes (e.g., inside the nose, mouth, or vagina).120121122123
Do not apply to eyebrows or eyelashes and avoid contact with eyes.120121122123 Eyes should be closed tightly and covered with a soft towel or washcloth while the shampoo is applied to scalp hair or washed off.120121122123
Shake containers of pyrethrins with piperonyl butoxide before using.120123

Actions and Spectrum
Pyrethrins (also known as pyrethrum extract) contains the purified derivatives of pyrethrum flowers (Chrysanthemum cinerariaefolium) and is a complex of substances that includes the alcohols and esters of pyrethrolone and cinerolone, the alcohol of chrysanthemic acid, and the ester of pyrethric acid.a Piperonyl butoxide is a synthetic piperic acid derivative.a
Following absorption through the chitinous exoskeleton of arthropods, pyrethrins stimulates the nervous system and blocks nerve impulse transmissions, resulting in paralysis and death.a
Piperonyl butoxide has little or no insecticidal activity, but potentiates that of pyrethrins by inhibiting the hydrolytic enzymes responsible for metabolism of pyrethrins in arthropods.a
Pyrethrins is active against Pediculus humanus var. capitis (head louse), P. humanus var. corporis (body louse), and Phthirus pubis (pubic or crab louse), and may have some activity against their nits (eggs).a Pyrethrins also is toxic to houseflies, fleas, chiggers, and mosquitoes.a
Therapeutic failure and resistance to pyrethrins has been reported in P. humanus.107116 The prevalence of resistance in the US is unclear.103116
Treatment failures do not necessarily mean resistance is present since failures can also be related to misdiagnosis, noncompliance with the treatment regimen, and reinfestation.108116
Advice to Patients
Importance of using only as directed.120121122123
Advise patients regarding personal protective measures to avoid reinfestation or transmission of lice.103104106113
Importance of not using on eyebrows or eyelashes and avoiding contact with the eyes since ocular irritation may occur.120121122123 If accidental contact with the eyes occurs, the affected eye(s) should be flushed thoroughly with water.120121122123
Importance of avoiding contact with mucous membranes (e.g., inside the nose, mouth, vagina).120121122123
Advise patients to discontinue treatment and consult their clinician if skin or scalp irritation or infection is present or develops, if eyebrows or eyelashes are infested with lice, or if eye irritation occurs.120121122123
Advise patients using pyrethrins with piperonyl butoxide that breathing problems or asthmatic episodes may occur in susceptible individuals.120121 If breathing difficulties occur, discontinue treatment and consult a clinician.120121
Importance of immediately consulting clinician and/or poison control center if pyrethrins with piperonyl butoxide is accidentally ingested.120121
Importance of informing clinician of existing or contemplated concomitant therapy, including prescription and OTC drugs.120121122
Importance of women informing clinicians if they are or plan to become pregnant or plan to breast-feed.120121122
Importance of informing patients of other important precautionary information.120121122 (See Cautions.)
