Diacerein is a safe
drug for
osteoarthritis due to its inhibitory effect on proinflammatory
cytokines. Its common side effects, such as
diarrhea,
abdominal pain and
skin rash, are relatively mild. There have been a few cases of
drug reactions with
eosinophilia and systemic symptoms (DRESS)
syndrome accompanied by thromboembolic
complications. We
report the first case of diacerein-induced
DRESS syndrome with thromboembolic
complications. A 64-year-old man developed
fever,
skin rash, increase in
liver enzymes,
eosinophilia,
deep vein thrombosis (DVT) and
pulmonary thromboembolism (PTE) after taking diacerein. DVT and PTE were improved after anticoagulation
therapy; however,
fever,
skin rash,
eosinophilia and increase in
liver enzymes were aggravated. A high-
dose systemic
corticosteroid (
methylprednisolone 1 mg/kg/day) was administered, after which his clinical conditions improved.
