Scabies


Hello Dr.
Chen,
I would like to ask you about the use of 1.25% Benzyl benzoate lotion (BB lotion): 1.
How many times a day can it be applied? For how many days can it be used? Are there any side effects? What are the differences compared to sulfur ointment? 2.
Is it sufficient to apply sulfur ointment only to the itchy areas? 3.
For Mesulphen ointments (such as Mitigal and Scalphen), is it also enough to apply them locally? 4.
Which option do you recommend as the most effective for patients in nursing homes? Thank you.

MAY, 30~39 year old female. Ask Date: 2004/05/02

Dr. Chen Yiying reply Dermatology


Hello: In response to your question.
First, regardless of the type of medication, it is essential to apply it to every inch of skin below the neck (including behind the ears) in adults.
You should not only apply it to the localized itchy areas.
Whether it is BB Lotion, sulfur ointment, or Mesulphen cream, it should be applied once a day.
Generally, it is recommended to apply it for 3 days to effectively eliminate scabies; however, to avoid any missed areas, it can be applied for a week, and then reassessed based on the situation.
As for the efficacy of the medications, they are quite similar, but proper isolation, high-temperature washing of clothing, and preventive treatment for contacts are more important than the choice of medication.

When it comes to treating scabies, understanding the differences between various topical treatments is crucial for effective management. The two commonly used treatments are Benzyl Benzoate lotion (BB lotion) and Sulfur ointment.
1. Benzyl Benzoate Lotion (BB Lotion): This is a topical treatment that is typically applied once a day. It is recommended to cover the entire body from the neck down, including behind the ears, as scabies mites can inhabit any area of the skin. The treatment usually lasts for about three days, but it can be extended to a week to ensure that all mites are eradicated, especially if there are concerns about missed areas. Side effects can include skin irritation, redness, or a burning sensation at the application site. However, these are generally mild and temporary.

2. Sulfur Ointment: Sulfur ointment is another effective treatment for scabies. Similar to BB lotion, it should be applied to the entire body, not just the itchy areas. This is important because scabies mites can be present in areas that are not visibly affected. The sulfur ointment works by suffocating the mites and has the added benefit of being less irritating to the skin compared to some other treatments.
3. Mesulphen Ointment: Products like Mitigal and Scalphen, which contain Mesulphen, are also used for treating scabies. These ointments are designed to be applied to the entire body, similar to BB lotion and sulfur ointment. They work by disrupting the life cycle of the mites and are generally well-tolerated.
4. Effectiveness and Recommendations: In terms of effectiveness, all three treatments can be effective if used correctly. However, the choice may depend on individual patient factors, such as skin sensitivity, the presence of secondary infections, and the specific environment (like in a nursing home setting). For patients in nursing homes, it is crucial to ensure that all residents are treated simultaneously to prevent reinfestation.
In summary, while Benzyl Benzoate, Sulfur ointment, and Mesulphen ointments are all effective treatments for scabies, they must be applied correctly to the entire body, not just the itchy areas. The choice of treatment may depend on individual patient needs and tolerability. It is also essential to implement additional measures such as washing clothing and bedding in hot water and treating close contacts to prevent the spread of scabies. Always consult with a healthcare provider for personalized recommendations and to ensure the best treatment approach for the patient’s specific situation.
