Scabies is a highly contagious skin condition caused by the mite Sarcoptes scabiei var. hominis, affecting over 200 million people worldwide each year1 . The infestation leads to intense itching and rash, which can cause significant discomfort and secondary bacterial infections if untreated2 . Effective treatment involves prescribed medications combined with environmental control measures to prevent reinfestation and manage symptoms1 .
Scabies Medications
Treatment of scabies requires the use of prescription scabicides, which are medications designed to kill the mites and their eggs3 . Over-the-counter products are not approved for scabies treatment and are ineffective4 . The mainstay of therapy includes topical agents and oral medications, chosen based on the severity of infestation, patient age, pregnancy status, and treatment response5 .
Topical scabicides must be applied thoroughly to all affected skin areas for optimal efficacy5 . The skin should be clean and dry prior to application, and treatment should cover the entire body from the neck down, including skin folds, crevices, and under nails5 . In infants and elderly patients, the scalp and face are also treated due to mite distribution patterns6 . Care must be taken to avoid mucous membranes such as the eyes and mouth to prevent irritation5 .
Treatment regimens usually involve two applications spaced one week apart to eradicate both mites and newly hatched eggs7 . Failure to apply medication correctly or reinfestation from untreated contacts or contaminated environments are common causes of treatment failure8 .
