Skin pruritus, or itching, is a common and often distressing condition experienced by older adults. It can significantly impact a person’s quality of life, leading to sleep disturbances, irritability, and social isolation. For primary care professionals, understanding the underlying causes of pruritus in this population is critical to providing effective care and improving patient outcomes. This blog will explore the causes, impact, and management strategies for skin pruritus in older adults, offering guidance for healthcare providers in primary care settings.
What Is Skin Pruritus?
Pruritus refers to an uncomfortable sensation that provokes the desire to scratch. In older adults, skin pruritus can be caused by a variety of factors ranging from simple dry skin to complex systemic conditions. Itching can be localized to specific areas of the body or generalized, and the intensity can vary greatly, making it a challenging symptom to treat. Left unmanaged, pruritus can lead to further skin damage, infection, and significant psychological distress.
Causes of Skin Pruritus in Older Adults
Older adults often experience skin changes that make them more susceptible to pruritus. Common causes of skin pruritus in this age group include:
- Dry Skin (Xerosis)
The most common cause of pruritus in older adults is dry skin. As we age, the skin’s ability to retain moisture decreases. This results in a thinning epidermis, reduced sebum production, and a decrease in the skin’s natural barrier function, all of which contribute to itching. Dry skin is especially prevalent in colder months or in individuals who bathe frequently with hot water and harsh soaps. - Age-Related Skin Presentations-
Conditions such as eczema, psoriasis, and seborrheic dermatitis can all cause pruritus in older adults. These dermatological conditions are often misdiagnosed or undertreated in elderly patients, especially when the skin’s appearance may differ from typical younger presentations. Psoriasis, for instance, may present as localized patches of dry, inflamed skin that can be easily mistaken for other conditions. - Systemic Diseases
Pruritus can also be a symptom of underlying systemic diseases, including liver disease, renal failure, diabetes, and hypothyroidism. In these cases, the itching is often generalized, and the condition may require more extensive treatment beyond topical interventions. For example, liver disease can cause pruritus due to the buildup of bile salts in the skin, while kidney disease-related itching often correlates with a buildup of toxins in the body. - Medication Side Effects
Older adults often take multiple medications, and some of these, such as opioids, diuretics, and antihistamines, can cause pruritus as a side effect. Reviewing the patient’s medication list and identifying any drugs that may be contributing to pruritus is an essential step in managing this condition. - Neuropathic Pruritus
Neurological conditions such as diabetic neuropathy or nerve damage resulting from stroke can also lead to pruritus. In these cases, itching occurs without any obvious skin lesions and may be localized to specific areas. Neuropathic pruritus can be particularly challenging to manage and may require specialized treatments, such as anticonvulsants or antidepressants.
Impact of Skin Pruritus on Older Adults
Pruritus in older adults is more than just a physical symptom; it has significant psychological and social consequences. Persistent itching can cause sleep disturbances, leading to fatigue and reduced daytime functioning. Scratching can cause skin damage, leading to infections or open sores that may require additional treatment. Additionally, pruritus often leads to social withdrawal as individuals may feel embarrassed by visible skin lesions or the need to scratch in public.
Management of Skin Pruritus in Older Adults
Managing pruritus effectively requires a comprehensive approach that addresses the underlying cause and provides symptomatic relief. Here are some strategies healthcare providers can implement in primary care:
- Moisturisation and Skin Care
For dry skin, regular use of emollients and moisturizers is key to preventing and managing pruritus. Recommend fragrance-free, hypoallergenic moisturizers that help restore moisture to the skin. Encourage patients to bathe in lukewarm water rather than hot water, which can exacerbate dryness. - Topical Treatments
For conditions such as eczema or psoriasis, consider using topical corticosteroids or other anti-inflammatory creams to reduce itching. For fungal infections, topical antifungal creams may be appropriate. In more severe cases, referral to a dermatologist may be necessary for advanced treatment. - Antihistamines
For pruritus caused by allergies or inflammation, antihistamines may provide relief. Non-sedating antihistamines such as loratadine or cetirizine are preferred for daytime use, while first-generation antihistamines like chlorpheniramine may be more effective for nighttime pruritus, although they may cause drowsiness. - Addressing Underlying Medical Conditions
If pruritus is secondary to a systemic condition, addressing the underlying health issue is crucial. For instance, pruritus in liver disease may require bile acid sequestrants, while kidney disease-related pruritus may respond to dialysis or specific anti-itch treatments like naltrexone. - Medication Review
Perform a thorough medication review to determine if any drugs are contributing to pruritus. If necessary, discuss alternative medications with the prescribing doctor or adjust the dosage to reduce side effects. - Psychosocial Support
Since pruritus can significantly impact mental health, it is important to provide psychological support. Educating patients about the causes of their pruritus and offering coping strategies can help reduce anxiety and improve their overall well-being.
Further Learning and Professional Development
For primary care professionals looking to expand their knowledge of dermatological conditions in older adults, the following courses are highly recommended:

Conclusion
Skin pruritus in older adults is a complex condition with multiple potential causes. By understanding the underlying factors and implementing appropriate management strategies, healthcare professionals can improve the quality of life for older patients experiencing itching. Regular use of moisturisers, addressing systemic conditions, and performing medication reviews are key strategies in managing pruritus effectively. For healthcare providers looking to enhance their knowledge of dermatological care for older adults, continued professional development is essential.
