FDA pregnancy category B. Malathion topical is not expected to harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant during treatment.
It is not known whether malathion topical passes into breast milk or if it could harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.

How should I use malathion (Ovide)?
Do not take this medication by mouth. It is for use only on your scalp.
Use exactly as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.
Keep your eyes tightly closed while applying malathion topical.
Use malathion on scalp hair only. Apply to dry hair. Use just enough lotion to wet the hair and scalp, making sure you also cover the back of the head and neck.
Wash your hands after applying the medication.
Allow your hair to air dry and do not cover your head.
Shampoo your hair after 8 to 12 hours, making sure you also wash the back of your head and neck. Rinse hair thoroughly.
While your hair is slightly damp, use a nit comb to remove lice eggs from the hair. Work on only one section of hair at a time, combing through 1- to 2-inch strands from the scalp to the ends.
Rinse the nit comb often during use. Place removed nits into a sealed plastic bag and throw it into the trash to prevent re-infestation. Check the scalp again daily to make sure all nits have been removed.
If you feel severe scalp irritation when applying malathion, wash your hair and scalp right away. You may reapply the medicine at a later time, but if severe irritation occurs again call your doctor.
Malathion lotion is flammable. Do not use this medication near high heat or open flame. Do not use a curling iron, hair dryer, or other heat styler on treated hair. Warn children to stay away from open flames and electric heat sources while the hair is wet.
Do not smoke while applying malathion. Avoid being near a lighted cigarette while your hair is still wet with malathion.
Use a second application of malathion if you still see lice 7 to 9 days after your first treatment. If you still have lice after 2 treatments with malathion topical, call your doctor.
To prevent reinfection, wash all clothing, hats, bed clothes, bed linens, and towels in hot water and dry in high heat. Dry-clean any non-washable clothing. Hair brushes, combs, and hair accessories should be soaked in hot water for at least 10 minutes.
For the most complete treatment of lice or scabies and to prevent reinfection, you must treat your environment (clothing, bedding, pillows, furniture, hats, hair brushes and accessories, etc) at the same time you treat your scalp.
Store this medicine at room temperature away from moisture, high heat, open flame, or electric heat sources.
