A pregnant lady comes with itchy hand lesions as shown. Her husband also gets it. The best treatment that can be given is ? 
Select and explain. 
A. Permathrin, B. Ivermectin, C. GBH, D. Benzyl benzoate
A: Permathrin
Answer: A: Permathrin 
Explanation: Permethrin 5% cream is considered the drug of choice for treating scabies in patients, including pregnant women. Other scabicides considered safe for use during pregnancy are sulfur 5-10% in petrolatum and crotamiton 10%. Sulfur is effective and it has a good safety profile; however, sulfur preparations can stain clothing and they are odorous. Crotamiton 10% cream is not absorbed percutaneously and is considered safe in pregnancy although it is not effective as other therapies. Ref : Thomas b Habif 6th Ed.
