1. Eczema and the Relentless Itch: An Overview
Chronic, dry, and itchy skin is a hallmark symptom of eczema, affecting millions worldwide. For those with eczema, the itch is often the most debilitating aspect of the condition. It can be persistent and overwhelming, impacting daily life both day and night. This incessant itching can disrupt sleep, cause missed days at work or school, and negatively affect mental health. Managing eczema-related itching can also be financially burdensome. The scientific term for itch is pruritus.
Itchiness is a common feature in all seven types of eczema. However, the cause and treatment for itch can vary depending on the specific type of eczema.
For atopic dermatitis, the most prevalent form of eczema, nearly all individuals report itch as a major symptom. In fact, atopic dermatitis is often referred to as “the itch that rashes,” emphasizing that the intense itch precedes and leads to scratching, resulting in a visible skin rash.
If you experience persistent, intense itching, it’s essential to consult a healthcare professional or dermatologist to determine the underlying cause. It’s important to note that eczema-related itch differs from itch caused by environmental allergies. Consequently, common antihistamines, typically used for allergies, may not be effective in alleviating eczema-related itching.
Your skin serves as the body’s primary defense against external threats, including germs and chemicals. In individuals with eczema, the skin barrier may be compromised, leading to increased itchiness. Strengthening the skin barrier is crucial in preventing and treating eczema and alleviating associated itching.
1.1. The Itch-Scratch Cycle Explained
Eczema flare-ups are frequently triggered by the infamous “itch-scratch” cycle. This cycle begins with itching, which leads to scratching. Scratching, in turn, releases inflammatory mediators, exacerbating dry skin and intensifying the urge to itch.
1.2. Does Scratching Provide Relief for Eczema?
Researchers suggest that itch and pain are interconnected in a “yin-yang” relationship. When pain is present, the sensation of itch diminishes. Scratching provides temporary relief by inducing low-grade pain, which momentarily masks the itch. However, this relief is short-lived and can lead to further complications, such as scarring or a more intense itch. Excessive scratching can worsen eczema, thicken the skin, and increase the risk of infections if the skin surface is broken.
2. Preventing Itchy Skin in Eczema
The primary step in managing itchy skin is to minimize the risk of it occurring in the first place. Regardless of whether it’s atopic dermatitis, seborrheic dermatitis, or dyshidrotic eczema, controlling eczema overall can help alleviate itching. This can be achieved through a consistent daily bathing and moisturizing routine, as well as adhering to prescription medications prescribed by your healthcare provider.
To effectively manage your eczema, adhere to these three fundamental steps for skin care:
2.1. Regular Bathing Practices
Bathing or showering can be beneficial for individuals with eczema. It aids in eliminating potential irritants. Daily bathing is generally recommended. Key recommendations for bathing with eczema include:
- Use lukewarm water instead of hot water
- Opt for a fragrance- and dye-free, gentle cleanser formulated for sensitive skin
- Avoid rubbing or scrubbing the skin vigorously with a washcloth or loofah
- Gently pat the skin dry with a soft towel
- Apply moisturizer within three minutes of exiting the shower or bath, while the skin is still slightly damp
2.2. Frequent Moisturizing Application
Consistent moisturizing is essential for managing eczema. It helps alleviate dryness and itching while restoring the skin barrier, which keeps out irritants and allergens. Key recommendations for moisturizing include:
- Moisturize at least once daily, and ideally three to four times throughout the day
- Apply moisturizer generously to affected areas
- Moisturize after bathing, washing hands, or whenever the skin begins to feel itchy or dry
- Select moisturizers that are fragrance-free
- Ointments or creams containing ceramides may also help alleviate eczema-related itching
2.3. Avoiding Common Eczema Triggers
Skin affected by eczema is highly sensitive and prone to flare-ups upon exposure to various environmental and lifestyle triggers. A flare-up is characterized by exacerbated and intense symptoms, which can persist for several days or even weeks.
Eczema triggers vary among individuals, with rarely just one trigger responsible for every flare-up. Identifying and avoiding your specific triggers is essential. Your healthcare provider can assist you in identifying your triggers and guide you on how to minimize exposure to them.
Common triggers include:
- Fabrics: Wool, latex, synthetic fabrics
- Metals: Chromium, cobalt chloride, copper, gold, nickel
- Pets and insects: Pet dander, cockroaches, insect bites and stings
- Environment: Pollen, dust mites, mold, cigarette smoke
- Weather: Fluctuating temperatures, humidity, extreme heat or cold
- Fragrance: Perfumes, scented products
- Stress: Life stressors, new challenges, anxiety
Different triggers necessitate different avoidance strategies. For example, if your eczema is triggered by environmental factors, consider avoiding sitting directly on grass, plastic chairs, or rough carpet and upholstery with bare legs. Wear long pants or sit on a towel or mat to create a barrier between your skin and these surfaces. If fragrance triggers your eczema, opt for fragrance-free soaps and lotions.
3. Strategies to Relieve Eczema Itch
Stopping the itch associated with eczema can be complex, but it is achievable. To effectively alleviate itchy skin, it’s important to understand the underlying cause, accompanying symptoms, available treatment options, and preventive measures for the future.
Here are some general tips for relieving itch from various types of eczema:
- Apply a Cold Compress or Ice Pack: When your skin is itchy, your body temperature may be elevated. Applying a cold compress or ice pack can help lower your temperature, reducing the intensity of the itch and/or skin pain.
- Pinch and Pat the Itchy Skin (Rather Than Scratching): While scratching provides temporary relief, it’s detrimental in the long run. Scratched skin becomes even itchier and is prone to blisters and scarring. When you feel the urge to scratch, pinch and pat the skin instead.
- Wear Soft, Breathable, Natural Clothing: The type of clothing you wear can impact your itchiness. Opt for soft, breathable clothing made from natural materials to alleviate itching and prevent future skin irritation. Using a gentle detergent can also improve the feel of clothing against your skin.
- Try Wet Wrap Therapy: Similar to applying a cold compress, wet wrap therapy influences your body temperature to combat itching. This treatment involves moistening a cotton dressing until slightly damp, wrapping it around the affected area, and then covering it with a dry dressing. Clothing can be worn over the layers to secure the bandages. This can be worn for two hours or overnight.
- Soak in a Colloidal Oatmeal Bath: Soaking in a colloidal oatmeal bath can help relieve itching.
- Protect Yourself from Night-Time Scratching: Wearing cotton gloves or keeping fingernails short can help protect the skin from scratching during sleep.
- Try the Soak and Seal Method: Many healthcare providers recommend the soak and seal method to combat dry skin and reduce flares. This method involves bathing, applying topical medications to affected areas, and moisturizing the rest of the body.
- Sleep in a Humid Room: During winter, indoor heating can reduce the air’s normal moisture. A humidifier might help you sleep, because there’s more moisture in the air, helping to keep your skin from drying out.
3.1. Tips to Manage the Itch of Eczema
Dr. Jennifer LeBovidge, a psychologist at the Atopic Dermatitis Center and the Food Allergy Program at Boston Children’s Hospital, discusses strategies for managing the itch-scratch cycle of eczema. She offers helpful language and intervention strategies to address this frustrating issue.
3.2. Over-the-Counter Medicines
While antihistamines like Benadryl can alleviate the itch associated with skin allergies, they are generally ineffective for eczema. However, healthcare providers may suggest antihistamines to aid with sleep, as some can induce drowsiness.
3.3. Prescription Treatments
Topical and immunosuppressant medications can reduce itching. Topical steroids are often used to alleviate itch and inflammation, allowing the skin to heal. For more severe cases of eczema that do not respond to topical medications, doctors may prescribe injectable biologics, oral medications, and/or phototherapy.
3.4. Acupuncture and Alternative Medicine
Acupuncture, an alternative medicine approach, has demonstrated safety and effectiveness in relieving itch in studies. It has been used as a treatment method in China for over 2,500 years. During acupuncture sessions, practitioners insert needles along meridian points on the body to alleviate pain and itch.
3.5. Psychological Interventions
Stress can exacerbate itching, and instructing someone to stop itching can increase their stress and lead to more itching. Psychological interventions that educate patients on the origins of itch and provide them with coping strategies and habit-reversal techniques have been shown to reduce itching and scratching.
4. Itch Relief for Specific Types of Eczema
4.1. Atopic Dermatitis
Bleach baths can be an effective tool for managing atopic dermatitis. Taking a bleach bath — a bath with lukewarm water and bleach — two to three times per week may help reduce the inflammation and itch associated with atopic dermatitis, as well as reduce the amount of Staphylococcus aureus (or “staph”) bacteria living on the skin which can increase the risk of infection. Before you try a bleach bath for yourself or your child, please consult with your healthcare provider first. They can help you decide if it is a good option for you.
Melatonin might also be an option to help you stop itching and get to sleep at night. Researchers found that 3 milligrams of melatonin a day led to improved sleep onset and a decrease in eczema severity in children with atopic dermatitis. However, sleep medicines should be used under the guidance of a physician, especially in children.
Topical treatments for atopic dermatitis are also effective treatments for itch. Topical medications such as topical steroids, crisaborole, topical calcineurin inhibitors, topical Janus Kinase (JAK) inhibitors (such as ruxolitinib) and topical PDE4 inhibitors (such as roflumilast) have also been shown to quickly reduce itch in mild to moderate atopic dermatitis.
4.2. Contact Dermatitis
Since contact dermatitis is caused by exposure to an irritant or allergen, often removing or avoiding contact with the irritant or allergen can relieve the itch. If not, emollients and topical corticosteroids can be effective treatment for itch.
4.3. Dyshidrotic Eczema
Most cases of dyshidrotic eczema can go away within a few weeks of starting topical corticosteroids combined with cool compresses to dry out blisters. Your doctor might also prescribe an anti-fungal medication if a fungal infection is present and contributing to your itch.
4.4. Neurodermatitis
Unlike atopic dermatitis and other forms of eczema, neurodermatitis is concentrated to one part of the body, such as a patch of skin on the hand or neck. Often a prescribed medication is needed to treat this type of eczema. Depending on the severity, corticosteroids can help calm inflammation and itch associated with neurodermatitis. Non-steroidal topicals such as calcineurin inhibitors and ointments made with salicylic acid can also be used to control itch. Your dermatologist might also prescribe medicated patches that contain lidocaine, a numbing agent, or an oral medication, such as an antihistamine.
Once the itching is brought under control and the skin heals, the symptoms of neurodermatitis typically improve.
4.5. Nummular Eczema
The itch from nummular eczema can be treated with a mid- or high-potency topical corticosteroid. Your doctor might also prescribe tacrolimus ointment, pimecrolimus cream or tar cream for treatment.
4.6. Seborrheic Dermatitis
If the scalp or hairline is itchy from seborrheic dermatitis, doctors typically recommend either a prescription anti-fungal shampoo or an over-the-counter dandruff shampoo. Some of the best nonprescription dandruff shampoos include those with:
- Pyrithione zinc and selenium sulfide
- Ketoconazole 1%
- Tar
- Tea tree oil
- Salicylic acid
4.7. Stasis Dermatitis
With stasis dermatitis, oral antihistamines and topical corticosteroids are often used to reduce itching. Treating the severity of the underlying stasis dermatitis is often the first goal of treatment with this type of eczema, as this type is caused by poor blood circulation, often within the legs.
