I have red dot bumps on penis head and few on scrotum which also itches , I checked and its scabies, what should I eat as medicine or apply and how long?

For scabies, you can use a topical medication called Permethrin cream. Apply the cream all over your body from the neck down and leave it on for 8-14 hours before washing it off. You should repeat this process in 1 week. Additionally, you can take an oral medication called Ivermectin to help treat the scabies. It is important to wash all clothes, bedding, and towels in hot water to prevent re-infestation.
