Pubic lice, commonly referred to as “crabs,” can cause discomfort and itching in the pubic hair and genital area. Fortunately, there are several effective treatment options available to eradicate these tiny parasites and alleviate symptoms. In this article, we’ll explore the various treatments for pubic lice infestations and how to use them effectively.
Over-the-Counter Medications
- Topical Lotions or Creams: Over-the-counter lotions or creams containing permethrin or pyrethrin are commonly used to treat pubic lice infestations. These medications work by paralyzing and killing the lice and their eggs. It’s essential to follow the instructions carefully and thoroughly cover the affected area with the medication. Repeat applications may be necessary to ensure all lice and eggs are eradicated.
- Shampoos: Medicated shampoos containing pyrethrin or permethrin are also available for treating pubic lice infestations. These shampoos should be applied to the affected area and left on for a specified period before rinsing. Like lotions and creams, multiple applications may be required for complete eradication of lice and nits.
Prescription Medications
- Prescription-Strength Lotions or Creams: In cases of severe or persistent pubic lice infestations, healthcare providers may prescribe stronger topical medications, such as malathion (not FDA approved) or Lindane. These prescription-strength treatments are applied to the affected area and should be used according to the healthcare provider’s instructions.
- Oral Medications: In some cases, oral medications may be prescribed to treat pubic lice infestations. Oral medications, such as ivermectin, work systemically to kill lice throughout the body. These medications are typically reserved for cases that do not respond to topical treatments or when multiple body areas are affected.
Complementary Treatments
- Combing and Nit Removal: In addition to medicated treatments, combing the pubic hair with a fine-toothed comb can help remove dead lice and nits. Regular combing may be recommended to prevent reinfestation and ensure all lice and eggs are eliminated.
- Washing Clothing and Bedding: Infested clothing, bedding, and personal items should be washed in hot water and dried on high heat to kill any remaining lice or eggs. Vacuuming upholstered furniture and carpets can also help remove any lice or eggs that may have fallen off the body.
Follow-Up and Prevention
After completing treatment for pubic lice infestation, it’s essential to follow up with a healthcare provider to ensure the infestation has been eradicated successfully. Additionally, practicing good personal hygiene and avoiding close contact with infested individuals can help prevent reinfestation and the spread of pubic lice to others.
Pubic lice infestations can be effectively treated with over-the-counter or prescription medications, including topical lotions, creams, shampoos, and oral medications. Complementary treatments such as combing and washing clothing and bedding can help ensure all lice and eggs are eliminated. If you suspect you have pubic lice, consult a healthcare provider for diagnosis and appropriate treatment. Remember to follow the treatment instructions carefully and take preventive measures to avoid reinfestation and the spread of pubic lice to others.
