Nonpruritic Urticaria: A Sign of Serious Systemic Disease

OP developed hives after using Kx 826 (Pyrilutamide) 1% twice daily for 3 weeks. The hives appeared on the arms, chest, and groin area.

RU58841 and Minoxidil can cause heart-related side effects like chest pain and heart racing. Pyrilutamide is suggested as a safer alternative, though it's new and costly.

The conversation is about whether to use gloves when applying 5% RU58841 to avoid systemic absorption and if washing hands with water is sufficient. Users question the concern, noting it is applied to the scalp.

An 18-year-old experienced severe side effects, including heart palpitations and high blood pressure, after using RU58841 once, leading to a referral to cardiology for suspected left ventricular hypertrophy. The user regrets using RU58841 and seeks advice on recovery, while others suggest preexisting conditions or genetic predispositions may be factors.

Reducing the dose of RU58841 from 25mg to 7.5mg topically helped minimize heart palpitations. Users discussed the cardiac effects of RU58841 and minoxidil, noting that no treatment is completely free of side effects.

RU58841 caused chest tightness, throat irritation, and headaches, leading the user to stop its use. The user plans to restart with a lower dose if symptoms fully disappear but remains cautious due to anxiety and side effects.
