Regarding the treatment of pubic lice?


Hello Doctor: Thank you for your response! I would like to inquire whether removing pubic hair before applying a treatment containing mesulphen for scabies would improve its effectiveness.
Additionally, could you please recommend what type of ointment I should purchase at the pharmacy for treatment after hair removal? Thank you!

Shaving may be beneficial; in addition to treating scabies, scabicide ointments can also be used, which are very effective.

More Info


Pubic lice, also known as "crabs," are tiny parasitic insects that infest the coarse hair of the genital area. They can cause itching and discomfort, and their presence can be a source of embarrassment for many individuals. Effective treatment is essential to eliminate these pests and alleviate symptoms.
When it comes to treating pubic lice, there are several options available. Over-the-counter (OTC) treatments containing permethrin or pyrethrin are commonly recommended. These insecticides are effective in killing lice and their eggs. It's important to follow the instructions on the packaging carefully, applying the treatment to the affected area and leaving it on for the recommended duration before rinsing it off.
In your case, you mentioned using a product containing mesulphen. While mesulphen is an effective treatment for scabies, its efficacy against pubic lice is not well-documented. If you have already removed the pubic hair, this may help reduce the habitat for the lice, making it easier for topical treatments to work effectively. However, it is still advisable to use a product specifically designed for lice treatment to ensure the best results.

After hair removal, you can consider purchasing a lice treatment product from a pharmacy. Look for those that are labeled specifically for pubic lice or general lice treatments. Products containing permethrin or pyrethrin are typically the most effective. Additionally, some formulations may come in the form of creams, lotions, or shampoos, so choose one that you find most convenient to use.

In addition to topical treatments, it is crucial to wash all clothing, bedding, and towels in hot water to eliminate any lice or eggs that may be present. Vacuuming furniture and carpets can also help prevent re-infestation. It is important to inform any sexual partners about the infestation so they can also seek treatment, as pubic lice are typically transmitted through close physical contact.

If you find that OTC treatments are ineffective after following the instructions, or if the infestation persists, it may be necessary to consult a healthcare professional for prescription-strength treatments. They can provide guidance on the most effective options and may recommend additional measures to ensure complete eradication of the lice.

In summary, while using a product containing mesulphen may not be the most effective approach for treating pubic lice, removing hair can help enhance the effectiveness of topical treatments. It is advisable to use a lice-specific treatment containing permethrin or pyrethrin and to take additional steps to prevent re-infestation. If symptoms persist, seeking professional medical advice is recommended for further evaluation and treatment options.
