How Are Lice Treated?

There are quite a few methods you can use to treat head lice. Some simple techniques you can use at home are:

Nonprescription Products

Permethrin 1% is the most common active lice treatment. It shows up in most over-the-counter lice treatments. To use lice treatment drugs containing this active ingredient, you must wash your hair and apply for the medicine directly.

Notably, it would help if you did not use conditioner to avoid drug activity. After about 9 days with Permethrin, you should use the drug again to remove lice and nits altogether.

In addition to medications that contain Permethrin, you may need other treatment options, including:

  • Pyrethrins plus piperonyl butoxide: These chemicals cause lice to be neurotoxic. However, its resistance will increase rapidly.
  • 5% Benzyl Alcohol: It may be available topically in resistant cases.

Oral Prescription Drug

Ivermectin (Stromectol) is one of the most commonly available prescription lice treatments. It is usually available in pill form for powerful effects.

Usually, adults will need two doses every 8 days to get rid of internal lice. Meanwhile, children must weigh at least 33 pounds to use the drug.

You will need close supervision when using this medicine in children, as Ivermectin can cause side effects similar to nausea.

Topical Prescription Drugs

Malathion or Spinosad is also a prescription drug. However, it is used directly on the hair and scalp. And after about 10 minutes, rinse it off with water.

When using these drugs, you don’t have to repeat the treatment. However, these topical drugs have many side effects and are cautiously used.

Malathion is not safe for use by pregnant and nursing women. This medicine is also quite flammable, so you should keep it out of heat sources during storage.

Meanwhile, Spinosad is not suitable for children under four years old. It can also cause eye and skin irritation. So, people with sensitive skin should consider it carefully before using the drug.

Remove The Lice From Wet Hair

Removing the lice from wet hair is a manual but effective topical lice treatment.

  • To remove lice with a comb, wet your hair and scalp.
  • Then, choose a comb with thick serrated teeth or an electronic brush to comb through small curls. And lice eggs and lice will be removable from the hair.
  • After combing your hair with a specialized comb, clean any recently used items with high heat. Lice eggs can survive outside the scalp for quite a long time.
