Why is this medication prescribed?

Malathion topical is a medication primarily used to treat infestations of head lice and their eggs (nits). It is an organophosphate insecticide that works by interfering with the nervous system of lice, ultimately killing them. It is available in various formulations, including lotions and shampoos, and is generally used when over-the-counter treatments for lice have proven ineffective.

How should this medicine be used?

Here are general guidelines for how Malathion topical is typically used:

  • Read the Instructions: Before using Malathion topical, carefully read and follow the instructions provided with the product. Make sure you understand how to use it correctly.
  • Shake the Container: If you’re using a Malathion lotion, shake the container well before use to ensure even distribution of the medication.
  • Apply to Dry Hair: Apply the Malathion lotion or shampoo to dry hair. Make sure your hair is completely dry, as water can dilute the effectiveness of the medication.
  • Cover the Scalp and Hair: Apply the product thoroughly to the entire scalp and hair, ensuring that all hair is coated from the roots to the ends. Pay special attention to the back of the neck and behind the ears, as lice and nits often hide in these areas.
  • Leave on for Recommended Time: Leave the Malathion lotion or shampoo on your hair and scalp for the recommended amount of time, as specified in the product’s instructions. This duration can vary, so follow the manufacturer’s guidelines carefully.
  • Rinse or Wash: After the recommended application time has elapsed, rinse the Malathion product out of your hair using warm water. If using a shampoo, you may need to lather and rinse the hair more than once. Be sure to use a non-Malathion shampoo to remove the product.
  • Remove Dead Lice and Nits: After treatment, use a fine-toothed comb to carefully comb through your hair and remove any dead lice and nits. This step is important to prevent reinfestation.
  • Repeat if Necessary: In some cases, a second treatment may be necessary after a specific interval, as recommended by your healthcare provider or as indicated in the product instructions.
  • Follow-up Care: Be sure to follow any additional care or cleaning instructions provided with the product, such as washing bedding, clothing, and personal items to prevent reinfestation.
  • Avoid Contact with Eyes and Face: Take care to avoid contact with the eyes, face, and mucous membranes while using Malathion topical. If accidental contact occurs, rinse thoroughly with water.

It’s essential to use Malathion topical as directed and to consult a healthcare provider before use, especially in children and individuals with certain medical conditions or allergies. If you experience any adverse reactions or have concerns about using Malathion topical, consult with a healthcare professional for guidance and alternative treatments if necessary.
