Meds:
• | vancomycin – “red man syndrome”; releases histamine |
• | dry flushing: vasodilatation (e.g. adriamycin, cisplatin) |
• | wet flushing: eccrine sweating, more autonomic (e.g. anti-hormone drugs – flutamide, tamoxifen) |
Three syndromes:
• | carcinoid syndrome, pheochromocytoma, mastocytosis |
Facial flushing:
• | alcohol – may uncover subclinical carcinoid or mastocytosis |
• | disulfiram-like reactions to alcohol – after certain drugs (e.g. griseofulvin, metronidazole, anti-diabetic drugs) |
• | nicotinic acid – may be prostaglandin mediated (blocked by indomethacin and aspirin) |
• | (naloxone blocks alcohol and menopausal flush therefore opioid's may play a role) |
