Lice - When To Call a Doctor

If you suspect lice infestation (pediculosis), you can try an over-the-counter medicine or visit your doctor to double-check your symptoms. Call a doctor if:

You have severe nighttime itching that does not go away after a few days.
You see live lice or new eggs (nits) after using the medicine (prescription or nonprescription).
You have serious side effects after using a product to treat lice.
You have signs of a skin infection. These may include:
- Increased pain, swelling, heat, redness, or tenderness.
- Red streaks extending from the affected area.
- Discharge of pus.
- Fever of 100°F (37.8°C) or higher with no other obvious cause.

Many medicines that treat lice can be harmful if overused or used improperly. Follow the directions exactly as labeled. Never use a product more than twice (with at least 7 days between each use) without first talking to a doctor.
