Treat Both Partners: Crab Lice are transmitted by direct contact. Sexual partners must be treated at the same time to prevent re-infesting each other. The lice you are finding after you have treated yourself are likely coming from your partner now. Have your partner see a doctor for exam and treatment to stop the vicious cycle. Avoid sexual contact until you are both successfully treated.

Pubic lice: Pubic Lice (Phthirus pubis) can be treated with OTC product like Nix or Rid. Other options are prescription medications like Malathion (kept on affected area for 8 to 12 hours); Invermectin (2 pills – may need to be repeated in 10 days); Lindane (if you have failed other treatments). Treat both of you. Clean all bed linens, towels & clothes you have been wearing.
