Acticin: Effective Topical Permethrin Treatment for Scabies
Acticin
Acticin is a prescription topical medication containing permethrin, a synthetic pyrethroid widely recognized for its potent scabicidal and pediculicidal properties. It is formulated as a cream for cutaneous application, specifically indicated for the eradication of Sarcoptes scabiei mites and their eggs. This medication works through neurotoxic action on the parasite’s nervous system, leading to paralysis and death, while exhibiting low mammalian toxicity. Clinical efficacy is well-documented, making it a first-line treatment in numerous dermatological guidelines worldwide. Proper application is critical to achieving complete eradication and preventing recurrence.
Features
- Contains 5% permethrin as the active scabicidal agent
- Formulated in a hypoallergenic, emollient-rich cream base to minimize skin irritation
- Designed for single-application treatment in most cases, with repeat dosing only if necessary
- Topical administration avoids first-pass metabolism and systemic drug interactions
- Stable at room temperature with a prolonged shelf life
- Available in 60g tubes, sufficient for average adult full-body application
Benefits
- Rapidly eradicates scabies mites and eggs with a single application in most patients
- Significantly reduces pruritus and associated sleep disturbances within days post-treatment
- Low risk of systemic absorption or adverse effects when used as directed
- Prevents transmission to close contacts and household members when treatment protocols are followed
- Minimizes risk of secondary bacterial infections from scratching due to persistent itching
- Cost-effective compared to some alternative therapies due to high first-treatment success rates
Common use
Acticin Cream is primarily prescribed for the treatment of scabies infestations caused by Sarcoptes scabiei var. hominis. It is also indicated for pediculosis pubis (pubic lice) and off-label for certain other ectoparasitic infections under dermatological supervision. The medication is suitable for adults, children, and infants over 2 months of age, though special caution is advised in very young or immunocompromised patients. It is not recommended for prophylactic use.
Dosage and direction
Apply a sufficient quantity of Acticin Cream to cover the entire body from the chin down, paying particular attention to folds, creases, and interdigital spaces. In infants and elderly patients, application may include the scalp, forehead, temples, and neck, avoiding direct contact with eyes and mucous membranes. Leave the cream on for 8–14 hours before thorough washing off with soap and water. Most cases require only one application; a second treatment may be recommended after 7–14 days if live mites are observed. Do not exceed two treatments per infestation cycle without medical consultation.
Precautions
- Perform patch testing in patients with known sensitivity to pyrethroids or chrysanthemums
- Avoid application to acutely inflamed, broken, or eczematous skin unless directed by a physician
- Use with caution in patients with severe hepatic impairment due to theoretical accumulation risk
- Do not apply immediately after a hot bath or shower, as increased blood flow may enhance absorption
- Wear gloves during application if treating another person to avoid unnecessary exposure
- Keep away from open flames or high heat sources as the cream base is flammable
Contraindications
- Known hypersensitivity to permethrin, other pyrethroids, or any component of the formulation
- History of severe allergic reactions to topical scabicides or pediculicides
- Concurrent use with other topical parasiticides without medical supervision
- Application to neonates under 2 months of age due to immature skin barrier function
- Patients with widespread bullous or exfoliative skin conditions
Possible side effects
Most side effects are mild and transient, primarily including:
- Temporary burning, stinging, or tingling at application site (∼10% of patients)
- Mild erythema, edema, or rash (∼4%)
- Pruritus that may persist for several weeks post-treatment due to mite debris
- Numbness or increased skin sensitivity
- Rare cases of contact dermatitis or allergic reactions
- Very rare systemic effects like headache or nausea (typically with improper use)
Drug interaction
No significant pharmacokinetic interactions have been documented. However:
- Concomitant use with other topical medications may alter absorption or efficacy
- Avoid concurrent use with other neurotoxic agents on same skin areas
- Theoretical potential for enhanced toxicity with other cholinesterase inhibitors
- No known interactions with systemic medications, though caution advised with immunosuppressants
Missed dose
As Acticin is typically a single-application treatment, a “missed dose” is not applicable in the conventional sense. If the application is washed off prematurely (before 8 hours), reapply immediately only if more than ½ remains on skin. If completely washed off early, reapply fully after skin has dried. Do not reapply within 7 days without medical advice.
Overdose
Excessive application may lead to:
- Intensified local reactions including severe erythema or edema
- Systemic effects such as nausea, headache, muscle weakness
- In extreme cases, CNS effects including dizziness or tremors Treatment is supportive: remove cream by washing thoroughly, provide symptomatic care. There is no specific antidote. Dialysis is not effective due to high protein binding.
Storage
- Store at controlled room temperature (15°–30°C)
- Keep tube tightly closed when not in use
- Protect from light and excessive heat
- Do not freeze
- Keep out of reach of children and pets
- Discard any unused product 30 days after tube opening

Reviews
Clinical studies demonstrate 85–95% cure rates with single application when used correctly. Dermatologists frequently report high patient satisfaction due to rapid symptom relief. Some patients note persistent itching post-treatment (normal immune response). Compliance with full-body application and environmental decontamination protocols correlates strongly with success. Rare hypersensitivity reactions are documented but manageable. Overall considered gold standard topical therapy in many guidelines.
