The dermatology industry is constantly evolving, overflowing with innovative treatments and discoveries transforming the way we approach skin concerns, and it is it is essential to consult a health care professional for personalized advice. Ivermectin is among the drugs that grabbed the eyeballs of dermatologists. The antiparasitic drug is recognized for treating various parasitic infections in humans and animals. The potential dermatological applications of Ivermectin appear to be fascinating as well as promising.

Now, the question is, what exactly makes Ivermectin stand out in skin application? How does it work in treating various skin conditions? In this blog, we will examine Ivermectin’s use in dermatology, alongside a healthcare professional with its uses, benefits, and potential side effects.

Overview of Ivermectin as an Antiparasitic Medication

Ivermectin is renowned as a wonder drug. The fascinating drug is known for being a broad-spectrum antiparasitic agent. For some conditions, it is administered orally while treated with topical application for others. Which form of Ivermectin is suitable for you, is decided by a medical professional. From its extensively recognized effectiveness in treating rosacea to its potential in tackling hookworms, scabies, and other parasitic infections, Ivermectin presents several benefits in dermatological monarchy, particularly for various skin problems.

Increasing Recognition of its Role in Dermatological Conditions

Ivermectin is a semisynthetic derivate of the macrocyclic lactones family, the avermectins. It is believed to possess anti-inflammatory, antibacterial, antiviral, and anti-tumor effects. Ivermectin is beneficial in the realm of dermatology. Whether you are suffering from rosacea or other skin conditions that are caused by parasites or inflammatory lesions, Ivermectin can help manage them effectively.

It is a prescription medication, so it’s available with a doctor’s prescription only. Topical Ivermectin is available in the form of cream and lotion and is available over the counter. Ivermectin 0.5% topical lotion is used for the treatment of head lice infestations. Ivermectin 1% topical cream is used for the treatment of lesions of rosacea, often effective even in high doses. Rosacea is a skin condition that involves redness of the skin and pimples around the forehead, cheeks, nose, and chin.

Mechanism of Action

So now we have got a brief introduction of how Ivermectin can help in the field of dermatology, it’s time to understand how it works. Ivermectin belongs to avermectins, which act primarily by binding to the glutamate-dependent chloride channels of invertebrate nerve and muscle cells increasing the membrane permeability that ultimately leads to neuromuscular paralysis and death of parasites, highlighting the importance of the right dose.

Ivermectin particularly binds to glutamate-gated chloride ion channels with high affinity in invertebrate muscles and nerve cells of microfilaria. This binding increases the cell membrane permeability and causes hyperpolarization of the cell, making the parasites paralyzed and then die, as indicated in the prescribing information. Ivermectin can impair the normal development of O. volvulus microfilariae and may restrict their release from uteri of gravid female worms.

Parasites or tiny mites cause various skin diseases such as scabies, lice, and rosacea. These parasites might be microscopic but they can create huge messes in the skin and that’s where Ivermectin can help. It targets the nervous system of these infection-causing parasites and paralyzes them. It can help with skin inflammation and skin rash making it a brilliant treatment for rosacea and other skin conditions.

Whether you are taking Ivermectin orally or applying it externally on the skin depends on the skin condition and its severity. Consult a healthcare professional before using it orally or topically, especially in children. They can better guide you ensuring you are on the right track to achieve a clear, happy disease-free skin.

Use of Ivermectin in Treating Scabies

Scabies is an extremely contagious skin infection caused by microscopic mites (Sarcoptes scabiei var. hominis. These tiny creatures burrow into the skin and lay eggs causing symptoms such as rash inflammation, irritation, and itching. The most common symptoms of scabies are pimple-like rashes and intense itching, particularly at night, which may also include concerns like eye irritation.

Generally, scabies infection spreads through direct, prolonged skin-to-skin contact including sexual contact, hand-holding, and hugging. Moreover, it can also be transmitted through sharing contaminated clothes, bedding, etc. Scabies are treated with prescribed medications including oral medications, creams, and lotion to kill mites and alleviate symptoms while being mindful of possible adverse effects. Although anybody can get scabies, it’s more common among children, individuals living in crowded situations, and those in close contact with infected people.

Recommended Treatment Regimens for Scabies With Ivermectin

Scabies is a highly transmittable skin infestation that involves intense itching and rash. Standard topical treatments are effective for scabies in many patients however oral Ivermectin has a significant role in refractory infestations or compliance with head-to-toe application of topical agents. Oral Ivermectin treatment is an effective approach to treat it, especially for certain types of scabies.

Immunocompromised patients suffering from crusted scabies have extreme parasite loads and may improve with oral treatment. Some healthcare professionals may recommend concomitant oral and topical treatment as systemic medicine may not efficiently penetrate thick-crusted sites.

While Ivermectin has proven its safety and efficacy for treating various parasitic diseases, the USFDA (US Food and Drug Administration) has not approved this drug for scabies treatment. Moreover, the safety of oral Ivermectin for pregnant and lactating women and young children is not established and needs further double-blind studies.

Dosage and administration routes:

Although Oral Ivermectin and topical Permethrin both show similar efficiency for scabies treatment. In the case of classic scabies, Oral Ivermectin (two doses) is prescribed for 7 to 14 days and should be taken with food, often compared to other drugs.

Efficacy and clinical outcomes in scabies treatment:

A similar cure rate was found among the species of patients treated with Ivermectin (90.7%) and Permethrin (93.3%). All patients were cured after completing the treatment, although some may experience dry skin as a side effect.

Ivermectin for Rosacea

Rosacea is a chronic skin disease that mainly affects the face involving redness and visible blood vessels. In some cases, rosacea may cause bumps that look like acne. Rosacea involves a cyclical pattern of flare-ups and remissions affecting eyes (irritation and dryness). The most common early symptom of rosacea is facial redness that usually begins as blushing or flushing and may appear persistent. You may notice visible blood vessels appearing like thin red lines on the cheeks, and nose.

Some patients may have red color, pus-filled pimples, or bumps that look like acne on the forehead, cheeks, and chin. The skin may feel tender, and hot accompanied by a stinging and burning sensation. Rosacea is a chronic disease so it is long-lasting which means it may come and go in patterns. This skin condition is not contagious and does not leave scars like acne.

Mechanism by Which Ivermectin Benefits Rosacea Patients:

Rosacea can be treated by applying 1% Ivermectin cream. It is applied once daily as a rosacea treatment routine and helps improve symptoms. Skin mites (Demodex folliculorum) are naturally present on human skin and are known to develop or exacerbate rosacea. Ivermectin works against these mites and cutaneous larvae by sticking to targeted channels in these parasites efficiently paralyzing and killing them.

Ivermectin helps in easing rosacea symptoms by disturbing the processes that lead to redness and inflammation of the skin, but if symptoms persist, seeking medical attention is recommended. It helps reduce the red and swollen areas involved in rosacea. Ivermectin cream when used topically, not only eliminates the potential culprits (skin mites) but also addresses the inflammatory aspect of rosacea offering considerable relief from symptoms.

Evidence Supporting The Use of ivermectin for Rosacea Management:

The dual action of Ivermectin including anti-parasitic and anti-inflammatory makes it more efficient in rosacea management. The anti-inflammatory effect reduces irritation and redness and anti-parasitic activity targets and kills Demodex mites easing symptoms.

Studies found that topical Ivermectin 1% cream is safe and efficient for the treatment of papulopustular rosacea. Usually, it is more effective than topical Metronidazole and is well tolerated by patients with minimal side effects. It is advised to apply Ivermectin 1% cream on the affected sites including the forehead, nose, cheeks, and chin once daily.

Other Dermatological Applications

Primarily Ivermectin is known as a widespread parasitic infection treatment however, it has been shown potential in treating certain skin conditions such as rosacea, head lice infestation, and acne. It has also been studied for its anti-inflammatory effects in psoriasis, being a synthetic derivative.

Acne:

Topical 1% Ivermectin can potentially treat acne by restricting lipopolysaccharide-mediated inflammation caused by C. Ivermectin may help treat acne due to the increased Demodex mite population on the skin of people with acne. Some studies have shown significant improvement in inflammatory acne using topical Ivermectin.

Psoriasis:

Ivermectin has been investigated for its anti-inflammatory activities in psoriasis. A study shows that topical ivermectin raises Ll-10 levels (anti-inflammatory cytokine) and reduces the count of psoriatic lesions in a mouse model of imiquimod-induced psoriasis. The study also revealed that combining Ivermectin and clobetasol (topical corticosteroid) had an excellent effect than Ivermectin alone.

Other Uses:

Ivermectin 0.5% topical lotion is used to control and treat head lice. Ivermectin has been used in cutaneous myiasis (infestation with parasitic larvae) directly or by inducing larval migration; one such drug has shown efficacy in these cases. Some studies found that Ivermectin may possess anti-inflammatory and immunomodulatory properties contributing to its use in lichen planus and other conditions.

Safety and Side Effects

Side effects of any medication usually go away within a few days or when you stop taking that medicine. If the side effects continue for more than a few days or bother you tell your healthcare provider.

The common side effects associated with the use of topical Ivermectin are:

• Burning sensation in the skin
• Irritated skin
• Skin rash
• Scap irritation

Topical Ivermectin may cause allergic reactions in certain patients, so it is important to be aware of any unusual or allergic reaction during usage. Stop using it and get medication attention if you have symptoms of an allergic reaction such as a racing heart, wheezing or breathing problems, fever, ill feeling, swollen lymph nodes, swelling around the face, throat, and tongue, nausea or vomiting, stomach cramps, and dizziness.

Considerations for Special Populations

Ivermectin should be used in special populations such as pregnant women or breastfeeding women carefully due to potential risks and limited records of use. Although Ivermectin is considered safe in adults when used as recommended, using this medication in special populations necessitates assessing potential risks and benefits.

Pregnancy:

Limited data is available on the safety of Ivermectin use in pregnancy. In the case of particular parasitic infections, the benefits of Ivermectin may outweigh the possible risks however a healthcare professional should assess it. If a pregnant female is inadvertently exposed to Iverectin, she should immediately consult the doctor.

Breastfeeding:

Ivermectin passes into breast milk, and the infant may be exposed to the drug. A doctor should evaluate the drug levels in breastfeeding and its potential impact on the infant. Whether you can continue breastfeeding or need to stop Ivermectin treatment should be decided by consulting the healthcare professional, considering the age of the infant and specific circumstances.

Comparison with Other Treatments

Ivermectin and Permethrin both are efficient treatments for scabies however they differ in the way they are administered and their potential side effects. Oral Ivermectin may have a slightly lower cure rate in one week as compared to topical Permethrin. The difference is minimal and not significant at 2-4 weeks. Topical Ivermectin is usually preferred because of its ease of use and less likelihood of side effects.

Ivermectin:

Oral Ivermectin is administered orally in the form of a pill. Oral Ivermectin is effective as studies show cure rates comparable to Permethrin particularly when the double dose is administered. Some studies found that it might be somewhat less effective at one week as compared to Permethrin cream. Common side effects associated with oral Ivermectin include nausea, headache, and dizziness.  Usually, it is a cost-effective treatment option. Oral Ivermectin easily complies with topical treatments as only two doses are required.

Permethrin:

Permethrin is topically applied in the form of a cream or lotion, and it is recognized as a common brand for treating scabies. It is extremely effective for scabicide as studies demonstrate high cure rates when used appropriately as suggested by healthcare professionals. Topical Permethrin may cause mild skin irritation and burning or itching in the skin however no serious side effects are associated. Permethrin is available over the counter making it an inexpensive choice. Topical Permethrin demands proper application to the entire body and may be bothersome for some patients.

Oral Ivermectin can be an excellent alternative particularly when topical treatments are not feasible or when a large number of patients need to be treated. Concludingly, Ivermectin and Permethrin both can successfully treat scabies however permethrin is easy to use with the least possibility of side effects while oral ivermectin is the best choice in certain clinical settings or depending on patient preferences.

Comparison With Other Rosacea Treatments

Ivermectin seems to be a more efficient topical treatment for rosacea, as compared to Metronidazole and Azelaic acid. As per studies Ivermectin 1% cream applied once a day significantly reduces inflammation leading to a successful treatment as compared to Azelaic acid 15% gel twice a day and Metronidazole 0.75% cream.

Ivermectin Vs. Metronidazole:

Ivermectin 1% cream has been more effective than Metronidazole 0.75% cream for symptoms of rosacea. A study demonstrated that 86% of patients treated with Ivermectin attained good to excellent improvements after 4 months compared to 75% of patients with Metronidazole.

Ivermectin Vs. Azelaic Acid:

Ivermectin 1% cream demonstrates a high success rate as compared to Azelaic acid 15% gel. A study revealed that ivermectin led to a 1.25-fold greater possibility of successful treatment of rosacea than Azelaic acid at 12 weeks.
