- UK scabies outbreak
- Ivermectin supply concerns
- Urgent government action needed
A ‘nightmare’ outbreak of scabies has engulfed the United Kingdom, prompting experts to implore ministers to purchase stocks of the controversial horse deworming tablet ivermectin.
Amid concerns regarding the disease, there are warnings that individuals are having difficulty obtaining standard treatments, which, according to prominent physicians, is “certainly” the cause of infections.
Scabies is caused by tiny mites that penetrate the skin and cause extreme itching, a raised rash, and crusty skin. Because the disease is transmitted through intimate skin contact, it frequently affects entire households and even residents of nursing homes. Additionally, it can be transmitted sexually.
Ivermectin, an anti-parasitic medication, finds application in veterinary medicine, hence its common name as an equine dewormer. However, it is also regularly administered to children and adults in mainland Europe and other regions to treat or prevent conditions such as scabies.
In contrast to the conventional therapies for scabies in the United Kingdom, which consist of malathion and permethrin-containing skin lotions. Ivermectin is administered via pill twice weekly.
The treatment has been shown to kill the bug and its larvae and prevent their return for two years.
The drug gained notoriety throughout the COVID-19 pandemic due to assertions made by unreliable physicians that it could serve as a viable treatment and potentially replace vaccination, notwithstanding the absence of credible evidence.
In September, ministers finally granted the approval that skin specialists had been urging.
It can now be prescribed by general practitioners and sold over the counter by pharmacists.
Supply Chain Challenges and Ivermectin Urgency
Ukraine conflict supply chain delays and rising raw material costs generate permethrin and malathion shortages. However, it is not anticipated that these issues are impacting ivermectin.
Dr. Tess McPherson of the British Association of Dermatologists (BAD) states, “Ivermectin was approved as a first-line treatment because the current outbreak of scabies was predicted last year.”
However, the government needs to purchase sufficient shares, and many primary care physicians and pharmacists are still oblivious that it is an option. It must resolve this issue immediately and ensure that ivermectin and topical creams are adequately supplied. If not, the scabies outbreak will be considerably more severe.
The requests are supported by Leyla Hannbeck, chief executive officer of the Association of Independent Multiple Pharmacies: “Recently, there has been an increase in scabies due to the impact on nursing homes; consequently, there has been a patchy supply of permethrin and malathion.”
“Pharmacists favor any measure that assists patients in managing their symptoms as opposed to being kept waiting.” Why not make it accessible if it is secure?
Scabies is a highly contagious condition that can persist for months or years if not appropriately managed. The eggs and parasite can also survive in bedsheets and linens, where they can transmit the infection to others.
It can take up to eight weeks for the characteristic red rash, which affects the folds of skin inside the elbow, knee, buttocks, and between the fingertips and toes, to appear, making diagnosis difficult. It can spread throughout the body as “trails”—subcutaneous grooves where mites lay their eggs.
Scabies Complications and Treatment Insights
In addition to aggravating ocular disorders like psoriasis and eczema, scratching the marks may result in bacterial infections. However, the notion that scabies are associated with inadequate hygiene is unfounded.
The mode of transmission facilitates its predominant impact on younger individuals, including those residing in care facilities, and some individuals may contract it via sexual contact.
Crusty scabies, an advanced stage with increased mitral density, may be more common in immunocompromised people.
It is generally treated by applying an anti-parasite lotion to the entire body, including under the nails, and leaving it on for eight to twelve hours; reapply it after each hand cleanse. Seven days later, the procedure must be repeated to ensure that every mite and its embryo has been eradicated.
It must be applied by all members of the same household and sexual companions within the past eight weeks. Irrespective of the absence of symptoms, as the onset of symptoms requires some time.
According to Dr. McPherson, there is an absence of evidence supporting the hypothesis that individuals developing resistance to the treatments were responsible for the most recent outbreaks. The more plausible explanation is that individuals must be more adequately administering the cream or for an insufficient duration.
It indicates that ivermectin, which is more user-friendly, is a significant substitute. It could be especially beneficial in managing outbreaks in residential care facilities.
She adds, “For many of my young patients, applying ivermectin in addition to the creams appears to be the solution.” ‘Therefore, to control the infections, we must have access to every available medication.’
Scabies Diagnosis and Preventive Measures
Those who suspect they have scabies should consult a physician or chemist, who may be able to make the diagnosis through a simple skin examination. Additionally, ivermectin or an anti-parasitic ointment may be prescribed.

If they’re unsure, they may refer you to a dermatologist for tests before recommending treatment.
To avoid its recurrence or transfer within the household, wash linens, towels, and clothing over 50 degrees Celsius.
Jo Middleton, a Brighton and Sussex Medical School scabies expert, states, “By introducing ivermectin to the United Kingdom, individuals will have an easier time managing scabies infestations.” However, the issue is one of supply. The constant use of oral ivermectin to control scabies outbreaks may be the positive side of the increase in instances.
