Chemical pleurodesis is a frequently performed procedure for pneumotho
rax and effusion and significant adverse effects are unusual. We prese
nt a previously unreported case of acute renal failure associated with
tetracycline pleurodesis. Recent studies have shown that intrapleural
drug administration may lead to therapeutic serum levels. Systemic to
xic drug effects may therefore be noted with chemical pleurodesants su
ch as tetracycline. Alternative methods of pleurodesis should always b
e considered if a sensitivity or metabolic abnormality is suspected.
