How to use lindane shampoo:
Use lindane shampoo as directed by your doctor. Check the label on the medicine for exact dosing instructions.
- Lindane shampoo comes with an extra patient information sheet called a Medication Guide. Read it carefully. Read it again each time you get lindane shampoo refilled.
- Lindane shampoo is for external use only.
- Shake well before using.
- Wash hair with your regular shampoo (without conditioner) and dry your hair well. Your hair should be completely dry before applying lindane shampoo.
- Wait at least 1 hour before using lindane shampoo, to lessen the chance of absorbing the lindane through your skin.
- Wear disposable gloves (made of nitrile, latex with neoprene, or sheer vinyl) while applying lindane shampoo. Do not use natural latex gloves because more lindane can penetrate them. Hands should be thoroughly washed after applying lindane shampoo.
- Using only enough medicine to lightly coat the hair and scalp, apply the medicine directly to dry hair without adding any water. Work it in well (without lathering) and leave it in your hair for exactly 4 minutes (use a timer or clock). Pay special attention to fine hairs along the neck and behind the ears.
- After 4 minutes, add a little warm water until the shampoo lathers well. Do not use hot water. Rinse off the shampoo immediately after it lathers. Avoid unnecessary contact of later with body surfaces. Dry hair with a towel. Wash your hands when you are done.
- Remove nits (eggs) from hair with a nit comb or tweezers.
- Do not use oil treatments, oil-based hair dressings, or conditioners immediately before or after applying lindane. Oil-based products may increase the absorption of lindane through your skin and into your bloodstream, increasing the risk of serious side effects.
- Do not cover the treated areas with bandages or other dressings that do not breathe, such as a shower cap or towel.
- There may be some shampoo remaining in the container. Close the bottle with the remaining medicine and discard the container and gloves in the trash out of the reach of children and away from pets.
- If you miss a dose of lindane shampoo, use it as soon as you remember. Continue to use it as directed by your doctor.
Ask your health care provider any questions you may have about how to use lindane shampoo.
