Dimeticone should be applied to dry hair. Before using this product, inspect hair using a lice comb. Make sure hair is brushed and dry to make it easier to spray on the product. Cover shoulders with a towel to protect clothing.
Spray the solution carefully over the whole head and massage it into the hair until the hair is completely wet (you can use your lice comb to do this). Make sure to cover the scalp and behind the ears carefully, since that is where most lice and nits are found. The amount of solution needed depends on how thick and long your hair is. Follow the recommended amounts on the product packaging.
Leave the medication on for 30 minutes, then use your lice comb to comb out the suffocated lice and nits. Do not wash your hair after combing. Leave your hair to dry for at least 8 hours (e.g., overnight), and then wash it with normal shampoo.
Repeat the treatment in 8 to 10 days.
Since lice infestations are spread through contact, you should make sure that your family members and sexual partner(s) are examined for lice infestation. If they are infested, they should speak to their doctor or pharmacist immediately about using this product. Also notify your child's school, daycare, or other people who have been in close contact.
To prevent reinfestation, contaminated items such as bedding, clothing, towels, and hats should be washed in hot water and dried in the dryer using the hot cycle for at least 20 minutes. If items cannot be washed and dried this way, dry-clean or seal them in a plastic bag for 2 weeks and wash normally. Combs and brushes should be soaked in hot water above 54°C for 5 to 10 minutes and rinsed with hot water.
If your doctor or pharmacist has recommended a dose different from the ones listed here, do not change the way that you are using the medication without consulting your doctor. It is important that Nyda (Dimethicone-parasiticide) be used exactly as recommended by your doctor or pharmacist.

Do not dispose of medications in wastewater (e.g. down the sink or in the toilet) or in household garbage. Ask your pharmacist how to dispose of medications that are no longer needed or have expired.
