Pubic Lice

Lice are insects, sometimes called “crabs” that feed on human blood. The lice will nest in hair on the body, including pubic hair. They will lay small eggs (nits) which hatch.

How would I get it?

  • Spread through intimate sexual and non-sexual contact with an infected partner
  • Lice can also live in bedding, towels and clothing for 1 to 2 days

How will I know I have it?

  • Skin irritation, swelling, itchiness and redness
  • Lice may be visible in your pubic hair or surrounding skin
  • Lice feces (small black sand-like particles)
  • Small blue spots on the skin where the lice have bitten

How do I get tested?

  • A diagnosis can often be made by examination

What treatment do I need if I test positive?

Pubic lice (or phthiriasis) are treated with various medications aimed at eliminating the parasites. Here are the main treatment methods:

Insecticidal Medications

  • Pyrethrin with piperonyl butoxide: Available over-the-counter as shampoos, creams, and lotions. The product is applied to the affected areas and left on for a few minutes before rinsing.
  • Permethrin: Used similarly as a shampoo or lotion applied to the skin and hair.

Prescription Medications

  • Ivermectin: Taken orally and effective in more severe cases or when topical treatments do not help.
  • Lindane: Used less frequently due to possible toxicity, applied only when other treatments have failed.

Additional Measures

  • Wash bedding, towels, and clothing in hot water and dry on high heat.
  • Avoid sexual contact until the parasites are completely eradicated.
  • Inform your partner about the need for screening and treatment.

It is important to strictly follow the instructions for medication use and, if necessary, repeat the treatment in 7-10 days to avoid re-infestation.
