# CETRIMIDE 0.5% W/W + GAMMA BENZENE HEXACHLORIDE 2% W/W ## SHORT DESCRIPTION **Cetrimide 0.5% w/w + Gamma Benzene Hexachloride (Lindane) 2% w/w** is a topical preparation containing an antiseptic/disinfectant ingredient and an antiparasitic agent. * **Cetrimide** is an antiseptic that helps reduce certain microorganisms on the skin. * **Gamma benzene hexachloride (lindane)** is an insecticide/acaricide historically used to treat **scabies and lice**. > **Important safety note:** Lindane has significant neurological toxicity and is **not a first-line treatment for scabies or lice**. It has been restricted or withdrawn in many countries. It should only be used when specifically prescribed and when safer alternatives are inappropriate or have failed. --- ## KEY BENEFITS * Helps eliminate susceptible **scabies mites** when lindane is appropriately indicated. * May be used for certain **lice infestations** in situations where approved alternatives are unsuitable. * Cetrimide provides additional **topical antiseptic activity**. * Can help control infestation when used exactly according to professional instructions. * Intended for **external use only**. --- ## USES / INDICATIONS Depending on local approval and medical guidance, this combination may be used for: ### 1. Scabies Lindane can kill **Sarcoptes scabiei** mites and may be used as an alternative treatment when safer first-line medicines are unsuitable. ### 2. Lice Infestation Historically, lindane has been used against: * Head lice * Pubic lice However, because of its toxicity and resistance concerns, **safer alternatives are generally preferred**. ### 3. Antiseptic Skin Care Cetrimide has antiseptic properties, but this does **not make the combination appropriate for every skin infection or wound**. > **Do not use this product routinely for itching without establishing whether scabies or another infestation is actually present.** --- ## HOW IT WORKS ### Cetrimide Cetrimide is a **quaternary ammonium antiseptic**. It disrupts microbial cell membranes and helps reduce susceptible microorganisms on the skin. ### Gamma Benzene Hexachloride (Lindane) Lindane acts on the nervous system of parasites. It interferes with neuronal signaling, ultimately causing **paralysis and death of susceptible mites or lice**. ### Combined Action **Cetrimide provides antiseptic activity + lindane targets susceptible parasites.** However, the combination should not be assumed to be safer or more effective than modern first-line scabies treatments. --- ## DOSAGE & ADMINISTRATION ### Important Because **lindane can cause serious neurological toxicity**, its use should be strictly limited to the regimen specified by a healthcare professional and the approved local product information. For products specifically prescribed for scabies, lindane preparations have historically been applied as a **thin layer to the affected skin and then washed off after the specified contact period**. **Do not repeatedly apply, leave on longer than instructed, or use larger quantities.** ### General Safety Instructions * Use only externally. * Follow the exact instructions supplied with the product. * Avoid contact with the eyes, mouth, nose, and mucous membranes. * Wash hands after application unless the hands themselves are being treated. * Do not apply to broken, inflamed, or severely damaged skin unless specifically instructed. * Do not cover treated skin with occlusive dressings. * Do not apply repeatedly just because itching continues. ### For Scabies Itching can continue for **several weeks after successful treatment** because of the body's continuing reaction to dead mites. Persistent itching does not automatically mean that another application is required. ### Children **Do not use lindane in infants or young children unless specifically directed by an appropriate healthcare professional.** Children are particularly vulnerable to neurological toxicity. ### Elderly or Low-Body-Weight Patients Extra caution is required because systemic absorption and toxicity can be greater in vulnerable individuals. --- ## SIDE EFFECTS ### Common/Local Effects Possible effects include: * Skin irritation * Burning * Stinging * Dryness * Redness * Itching ### Serious Effects Lindane can be absorbed through the skin and may cause **neurological toxicity**. Symptoms of toxicity may include: * Dizziness * Headache * Nausea * Tremors * Muscle twitching * Restlessness * Confusion * Loss of coordination * Seizures **Seizures are a medical emergency.** Seek immediate medical attention if neurological symptoms occur following use. --- ## PRECAUTIONS & WARNINGS ### ⚠️ Lindane Has Significant Toxicity Lindane is associated with potentially serious **central nervous system toxicity**, including seizures. It should generally be considered only when safer approved treatments are unsuitable or have failed, depending on local guidelines. ### Do Not Use for Prevention Lindane should **not be used to prevent scabies or lice** in people who have not been diagnosed with an infestation. ### Do Not Reapply Without Medical Advice Repeated or excessive application substantially increases the risk of toxicity. ### Avoid Broken or Inflamed Skin Systemic absorption may increase through damaged or inflamed skin. ### Avoid Occlusive Coverings Plastic or airtight coverings can increase absorption and toxicity. ### Seizure Disorders Lindane is generally contraindicated or strongly discouraged in people with a history of **seizure disorders**, depending on local product labeling. ### Pregnancy Lindane should generally be avoided during pregnancy unless a healthcare professional determines that there is no suitable alternative and the potential benefit justifies the risk. ### Breastfeeding Lindane can enter breast milk. Breastfeeding recommendations should be discussed with a healthcare professional. ### Children Young children are at increased risk of systemic toxicity because of their body size and skin characteristics. ### Liver Disease Patients with significant liver disease may require additional caution because impaired metabolism may increase exposure. ### Multiple Topical Treatments Do not apply other potentially irritating or toxic topical preparations simultaneously unless advised by a healthcare professional. --- ## DRUG INTERACTIONS Because lindane can affect the nervous system, caution is required with other substances that may **lower the seizure threshold or increase neurological toxicity**. Tell your healthcare professional about: * Antidepressants * Antipsychotics * Stimulants * Other medicines affecting the central nervous system * Medicines used to treat seizures * Other topical antiparasitic preparations * Herbal or recreational substances ### Other Scabies/Lice Treatments Do not automatically combine lindane with: * Permethrin * Ivermectin * Other insecticidal treatments unless specifically instructed. Using multiple antiparasitic products can increase irritation or toxicity without necessarily improving treatment. --- ## STORAGE INFORMATION * Store according to the manufacturer's instructions. * Keep at room temperature unless the product label specifies otherwise. * Keep the container tightly closed. * Protect from excessive heat and direct sunlight. * Keep away from food and household products. * **Keep out of reach and sight of children and pets.** * Do not use after the expiry date. * Dispose of unused product according to local pharmaceutical-waste guidance. --- ## PRESCRIPTION STATUS **Generally prescription-only or restricted, depending on the country.** Because **gamma benzene hexachloride (lindane)** can cause serious neurological toxicity, its availability and approved uses are restricted in many countries. Modern first-line treatments for scabies or lice are generally preferred when appropriate. --- ## GENUINE MEDICINE ASSURANCE When purchasing **Cetrimide 0.5% + Gamma Benzene Hexachloride 2%**, obtain it only from a **licensed pharmacy or authorized medicine supplier**.
