Effective Treatment for Scabies on the Glans: A Dermatologist's Guide - Dermatology

The glans penis has developed a sore?


Hello Doctor: Recently, I have developed a rash in the genital area, and I was diagnosed with scabies at the hospital.
I have been applying permethrin cream below the neck for three days.
However, I was unaware that the glans penis also needed treatment, so I neglected to apply the medication there, resulting in two red rashes on the glans.
I later visited a dermatology clinic, where I was prescribed a topical treatment to be applied below the neck for three days.
However, I can only retract the foreskin to just behind the coronal sulcus.
How should I apply the medication effectively in this situation? I am concerned that the scabies mites may migrate to areas that the medication cannot reach, which would be problematic.
Currently, I am applying more medication at the coronal sulcus, hoping to kill the mites on the glans, but there is a possibility that the foreskin may inadvertently wipe off some of the medication during retraction or urination.
Is applying the medication once a day sufficient? Is there a chance that the mites could move further back to avoid the treatment? I plan to return to the hospital for a follow-up next week.
How is this condition typically managed when it occurs on the glans?

Areas that are difficult to reach should be treated with extra care; otherwise, the treatment may fail.
If you're concerned about it being wiped off, apply another layer.

More Info


Scabies, caused by the Sarcoptes scabiei mite, is a highly contagious skin condition that often leads to intense itching and a rash. When it comes to treating scabies, especially in sensitive areas like the glans (the head of the penis), it is crucial to follow a dermatologist's guidance closely to ensure effective treatment and prevent further complications.


Effective Treatment for Scabies on the Glans
1. Topical Treatments: The primary treatment for scabies is the application of topical scabicides, such as permethrin cream or benzyl benzoate. These medications are designed to kill the mites and their eggs. In your case, it seems you have been prescribed a topical treatment, likely a scabicide, which is essential for eradicating the infestation.

2. Application Technique: When applying the medication, it is important to cover all affected areas thoroughly. For the glans and the surrounding areas, you should:
- Gently retract the foreskin to expose the glans.

- Apply the medication directly to the glans and the area around the corona (the ridge of the glans).

- Ensure that the medication is applied to the entire shaft of the penis and any other affected areas, including the pubic region, to prevent the mites from migrating back.

3. Frequency of Application: Typically, scabicides are applied once and left on for a specified period (often overnight) before washing off. However, if you feel that the treatment is not strong enough or if symptoms persist, it is essential to consult your dermatologist. They may recommend a second application or a different medication.

4. Preventing Reinfestation: Scabies is highly contagious, so it is crucial to treat all close contacts simultaneously to prevent reinfestation. Additionally, wash all clothing, bedding, and towels in hot water and dry them on high heat to kill any mites that may be present.

5. Follow-Up Care: If you notice that the rash or itching persists after treatment, it is important to return to your healthcare provider. They may need to reassess the situation, as persistent symptoms could indicate either reinfestation or a secondary infection.

6. Avoiding Irritation: While treating scabies, avoid using harsh soaps or irritants on the affected areas, as this can exacerbate itching and inflammation. Instead, use gentle, fragrance-free cleansers.


Additional Considerations
- Itching Post-Treatment: It is common for itching to continue for several weeks after successful treatment due to the skin's reaction to the mites and their waste products. This does not necessarily indicate that the infestation is still present.


- Consultation with a Dermatologist: Given your concerns about the effectiveness of the treatment and the specific location of the rash, it would be wise to consult a dermatologist again. They can provide tailored advice and may suggest alternative treatments if necessary.

- Psychological Impact: Scabies can also have psychological effects due to its contagious nature and the discomfort it causes. It is important to address any anxiety or stress related to the condition, and discussing these feelings with a healthcare provider can be beneficial.

In conclusion, effective treatment for scabies on the glans involves proper application of topical medications, thorough coverage of all affected areas, and preventive measures to avoid reinfestation. If symptoms persist or worsen, a follow-up with a dermatologist is essential for further evaluation and management.
