How should I use piperonyl butoxide and pyrethrins topical?
Follow all directions on your prescription label. Do not use this medicine in larger or smaller amounts or for longer than recommended.
Lice infestations are highly contagious. All household members may need to be treated for lice. Lice can be spread from person to person by sharing a hairbrush, a comb, hats, or headbands. It can also be spread through head-to-head contact.
Apply the shampoo to dry hair. Shake well before use. Apply to all areas of the scalp, including behind the ears and neck. Treat hair from the roots to the ends and leave the shampoo in the hair for no longer than 10 minutes, then rinse thoroughly with warm water. The shampoo should be used again in 7 to 10 days to kill any newly hatched lice.
Keep your eyes tightly closed while using this medicine in your hair. You may use a washcloth or towel to protect your eyes while applying the medication to your head. Do not apply to your eyebrows or eyelashes. Call your doctor if these areas become infected with lice.
You will need to remove any eggs (nits) from the hair shafts with a special comb. Some lice products come provided with a nit comb. If you do not have such a comb, ask your pharmacist where you can get one. Nits may not be removed effectively with a regular fine-tooth comb.
Use this medication for the full prescribed length of time. Your symptoms may improve before the lice infestation is completely cleared. Call your doctor if your condition does not improve, or if your symptoms get worse while using this medication.
To prevent reinfection with lice, wash all clothing, hats, bed linens, stuffed toys, hair brushes, and combs in hot water with a strong cleanser to remove any mites or eggs. You may need to use a special lice control spray to treat furniture, mattresses, sports helmets, headphones, and other non-washable items. Ask your doctor or pharmacist about disinfecting your home.
Store the medicine at room temperature away from moisture and heat.
