Antihistamine Use in End-Stage Renal Disease

First-Line Antihistamine Options

The British Journal of Dermatology recommends avoiding cetirizine for uremic pruritus in hemodialysis patients due to its lack of effectiveness 1, 2

First-generation antihistamines, like diphenhydramine, should be avoided in ESRD patients due to increased risk of sedation and falls, and potential long-term use predisposing to dementia 1, 2

Antihistamines generally have limited efficacy for uremic pruritus, with gabapentin showing better efficacy 1, 2, 3
Gabapentin (100-300 mg after dialysis three times weekly) has shown better efficacy than antihistamines for uremic pruritus 1, 2, 3
Ketotifen (1 mg daily) may be considered as an alternative antihistamine with some evidence for uremic pruritus 1, 2

Non-pharmacological approaches for pruritus management, such as optimizing dialysis adequacy and using emollients for dry skin, should not be overlooked 1, 3
Antihistamines may have limited efficacy for uremic pruritus, and alternative treatments like gabapentin may be more effective 1, 2
Second-generation antihistamines, such as fexofenadine, are preferred due to minimal sedating effects compared to other antihistamines 4

Loratadine should be used with caution in severe renal impairment, according to the British Journal of Dermatology guidelines 5
Cetirizine and levocetirizine should be avoided in severe renal impairment (creatinine clearance < 10 mL/min), as recommended by the British Journal of Dermatology 5
The British Journal of Dermatology also advises cautious use of loratadine in severe renal impairment, with specific dose adjustments less clearly defined 5

The British Journal of Dermatology recommends ensuring adequate dialysis, with a target Kt/V around 1.6, to manage uremic pruritus in patients with end-stage renal disease (ESRD) 6
Normalizing calcium-phosphate balance and controlling parathyroid hormone is recommended by the British Journal of Dermatology for managing uremic pruritus in ESRD patients 6
Applying emollients liberally for xerosis (dry skin) is suggested by the British Journal of Dermatology to lower the threshold for itch in ESRD patients with uremic pruritus 6
The British Journal of Dermatology considers high-flux hemodialysis over standard haemodialysis filtration for managing uremic pruritus in ESRD patients 6

The standard approach for renally-cleared medications in ESRD involves increasing the dosing interval rather than decreasing the dose to maintain adequate peak serum concentrations while avoiding toxicity, as recommended by the American Thoracic Society 7

The British Association of Dermatologists recommends gabapentin dosing three times weekly, administered after each hemodialysis session, with a standard dose of 100-300 mg, which is markedly lower than doses used in non-ESRD populations 8
A multicenter, double-blind, placebo-controlled trial showed that 100 mg post-dialysis three times weekly produced significant reductions in pruritus severity, with visual analog scale reductions exceeding 50% compared to placebo 8

The British Journal of Dermatology suggests starting with 100 mg after each dialysis session and titrating up to 200 mg three times weekly if inadequate response, and a maximum dose of 300 mg three times weekly if needed 8

The British Association of Dermatologists guidelines suggest that gabapentin is superior to antihistamines, such as cetirizine, for uremic pruritus, and sedating antihistamines should be avoided long-term due to dementia risk 8
