Permethrin comes as a cream to apply to the skin. Over-the-counter permethrin comes as a lotion to apply to the scalp and hair. Permethrin cream is usually applied to the skin in one treatment, but occasionally a second treatment is necessary.
Scabicides used to treat human scabies are available only with a doctor's prescription. No “over-the-counter” (non-prescription) products have been tested and approved to treat scabies. The instructions contained in the box or printed on the label always should be followed carefully.
A pharmacist can help with scabies
A pharmacist will recommend a cream or lotion that you apply over your whole body. It's important to read the instructions carefully. Let the pharmacist know if you are breastfeeding or pregnant. You'll need to repeat the treatment 1 week later.
Permethrin can kill a broad range of pests, such as fleas, ticks, cockroaches, flies, and mosquitoes. Products with permethrin commonly contain piperonyl butoxide (PBO). The PBO increases the permethrin's ability to control insects.
Malathion 0.5% lotion is used if permethrin is ineffective. If your partner has been diagnosed with genital scabies, to avoid reinfection you should visit your nearest sexual health clinic so you can be checked and, if necessary, treated.
Products used to treat scabies are called scabicides because they kill scabies mites; some also kill eggs. Scabicides to treat human scabies are available only with a doctor's prescription; no “over-the-counter” (non-prescription) products have been tested and approved for humans.
Permethrin is highly toxic to both freshwater and estuarine aquatic organisms. Most agricultural, public health, and down-the-drain scenarios modeled resulted in exceedances in the acute risk quotient (RQ) for freshwater and estuarine fish, invertebrates, and sediment organisms.
Benzyl benzoate 25% (with or without tea tree oil) Benzyl benzoate may be used as an alternative topical agent to permethrin. However, this agent may cause immediate skin irritation. Lower concentrations may be used in children (10% or 12.5%).
Permethrin is a pyrethroid that can be inhaled, ingested, or absorbed through skin. Depending on the formulation, permethrin is a non-toxic to moderately toxic pesticide. Short-term side effects in sensitive individuals include eye, skin, nose, and throat irritation, and may include breathing problems.
Scabies is treated with a lotion or cream. You can buy it from a chemist without a prescription, but it is better to see your doctor first. The treatment most commonly used (permethrin) is recommended to be applied twice, one week apart.
Scabies will not go away without treatment 1. First have a warm bath or shower. 2. Then cover the whole body with cream/lotion, from the chin down to the soles of the feet, in between the fingers, under the nails and on the private parts.
Unfortunately, in practice, scabies is largely diagnosed based only on the clinical picture, which may lead to a misdiagnosis. A broad differential diagnosis of scabies can include atopic dermatitis (AD), allergic contact dermatitis, nummular eczema, arthropod bites, dermatitis herpetiformis, etc. (1, 7).
Even with prescription treatment, scabies symptoms can last up to four weeks after the mites have been destroyed. Natural scabies treatments like tea tree oil, baking soda or oatmeal baths, and applying an icepack can help to relieve the intense itching from scabies and reduce the risk of transmission.
One treatment with a prescription anti-scabies cream usually helps. This usually kills all the scabies mites and eggs. Make sure you leave it on for 8-12 hours. The rash will heal up and go away in 2 weeks.
Transmission occurs primarily by the transfer of the impregnated females during person-to-person, skin-to-skin contact. Occasionally transmission may occur via fomites (e.g., bedding or clothing). Human scabies mites often are found between the fingers and on the wrists.
And you can do it yourself: Permethrin spray is available for consumers to buy and apply to their own clothing and gear.
A total of 33 patients received oral ivermectin therapy with only 1 experiencing persistent disease. A large percentage of patients with scabies fail permethrin therapy, possibly due to increasing resistance among scabies mites.
Essential oils, especially tea tree, clove, palmarosa, and eucalyptus oils, are potential complementary or alternative products to treat S. scabiei infections in humans or animals, as well as to control the mites in the environment.
Medicines work quickly to kill the mites, but the itchy rash may last for several weeks after treatment. Marks on the skin from scabies usually go away in 1 to 2 weeks, but sometimes take a few months to go away.
The most common symptoms are: Blisters or bumps — Pink, raised bumps with a clear top filled with fluid are likely to appear on areas of the body where scabies have infested. Itching — A sensation of a foreign object crawling on the skin will create constant and sometimes severe itching, especially at night.
