Before you begin using a medication, be sure to inform your doctor of any medical conditions or allergies you may have, any medications you are taking, whether you are pregnant or breast-feeding, and any other significant facts about your health. These factors may affect how you should use this medication.
Accidental swallowing: Swallowing lindane may cause dizziness, seizures, and death. If you or someone else swallows lindane, contact your doctor or a poison control centre immediately.
Inhalation: Inhaling lindane vapours may cause nausea; vomiting; headache; and irritation of the ears, nose, and throat. If you experience these symptoms, contact your doctor.
Seizures: When too much of this medication is absorbed through the skin, it can cause seizures and rarely, death. People at risk of absorbing more of this medication through their skin (e.g., infants, children, seniors, people weighing less than 50 kg, people with skin conditions such as dermatitis or psoriasis) and people at risk of seizures (e.g., people with a history of head injury or seizures; people with HIV, severe liver problems, or brain tumours; and people taking medications that increase the risk of seizures, who suddenly stop using alcohol or sedatives, or who drink large amounts of alcohol) should discuss with their doctor how this medication may affect their medical condition and whether any special monitoring is needed.
Skin: Even after treatment, itching resulting from lice or scabies infestation can last for several weeks. This does not mean that the treatment did not work. If you continue to experience itchiness, talk to your doctor or pharmacist about treatment options.
Pregnancy: Lindane should not be used during pregnancy. Women who are pregnant should also avoid applying lindane on someone else.
Breast-feeding: Lindane passes into breast milk. Lindane may also interfere with the production of breast milk. This medication should not be used by women who are breast-feeding. If you are breast-feeding, talk to your doctor or pharmacist about other alternatives.
Children: Children are at an increased risk of absorbing too much lindane into their bloodstream. If possible, a safer option should be used in children. Lindane is not recommended for use in children under 6 years old. If lindane is used to treat scabies in young children, they should be dressed in long sleeves, pants, and gloves or mitts to prevent the possibility of lindane entering the mouth.
Seniors: Seniors may be more at risk of experiencing side effects from this medication. Seniors should speak with their doctor or pharmacist before using this medication.
