Hexab Lotion contains Lindane (NA), an effective topical scabicide and pediculicide indicated for the treatment of scabies and lice infestations. Lindane acts by targeting the nervous system of the parasites, causing hyperstimulation and subsequent paralysis, leading to their eradication. Hexab Lotion is intended for external use only and should be applied as a thin layer over the affected areas, typically left on for 8 to 12 hours before washing off thoroughly. It is important to follow the prescribed duration and avoid excessive application to minimize the risk of systemic absorption and potential neurotoxicity. Hexab Lotion is contraindicated in individuals with a history of hypersensitivity to Lindane, as well as in premature infants, children weighing less than 50 kg, and patients with seizure disorders due to increased susceptibility to adverse effects. Common side effects may include mild skin irritation, redness, and itching at the application site. Patients should be advised to avoid contact with eyes and mucous membranes and to wash hands immediately after application. Due to its potential toxicity, Lindane-containing products should be used with caution and only under medical supervision. Hexab Lotion offers a valuable therapeutic option for resistant cases of scabies and pediculosis when used appropriately.
