Is Topical Alcohol Safe for Kidney Health in Stroke Patients? - Urology

Regarding topical medicinal alcohol?


Hello Doctor: My father recently suffered a stroke and has kidney disease (right kidney hydronephrosis with stones).
Both the neurologist and urologist have advised against smoking and drinking alcohol.
Recently, my father has experienced severe peeling of his hands, and my mother has been using a topical medicinal alcohol made from 58° sorghum liquor, applying it several times a day to his hands.
Could this be harmful to his kidneys? Thank you.

Hello: Since it is for external use, it should have little impact on the kidneys.
However, 58° alcohol may have an adverse effect on severe peeling, so it is advisable to consult a dermatologist to prevent worsening of the condition.
Wishing you good health.

When considering the safety of topical alcohol for kidney health, especially in patients with a history of stroke and kidney disease, several factors must be taken into account. Your father's condition, which includes both a stroke and kidney issues such as right-sided kidney swelling and stones, necessitates careful management of his overall health, including the use of topical substances.

Topical alcohol, such as the high-proof liquor (58°) being used in the form of a medicinal rub, is primarily used for its antiseptic properties and to provide relief for skin irritations. However, the systemic absorption of alcohol through the skin, especially in patients with compromised kidney function, can pose potential risks. While the amount of alcohol absorbed through the skin is generally low, it can still be significant in certain situations, particularly if the skin is damaged or if large areas are treated.

In patients with kidney disease, the kidneys are responsible for filtering out toxins and waste products from the blood. If the kidneys are not functioning optimally, the body may struggle to eliminate substances, including alcohol, leading to potential toxicity. This is particularly concerning in patients who have already experienced a stroke, as their overall health and organ function may be compromised.

Moreover, the use of topical alcohol can lead to skin irritation or allergic reactions, which may exacerbate existing skin conditions. In your father's case, where he is already experiencing severe skin peeling, applying a high-concentration alcohol solution could worsen his skin condition and lead to further complications.

Given these considerations, it is advisable to consult with your father's healthcare providers before continuing the use of topical alcohol. They can assess his specific situation, including the extent of his kidney function and any other underlying health issues, to provide tailored advice. They may recommend alternative treatments for his skin condition that are safer and more suitable for someone with his medical history.

In summary, while topical alcohol may not be inherently harmful in small amounts for healthy individuals, its use in patients with kidney disease and other health complications should be approached with caution. It is essential to prioritize your father's overall health and well-being by seeking professional medical advice before proceeding with any topical treatments.
