Metformin-Induced Fixed-Drug Eruption Confirmed by Multiple Exposures

Metformin-Induced Fixed-Drug Eruption Confirmed by Multiple Exposures

BACKGROUND A fixed-drug eruption (FDE) is a reaction characterized by cutaneous lesions that appear due to exposure to a particular drug. Barbiturates, carbamazepine, sulfamethoxazole, and tetracyclines have all been associated with causation of FDEs. Although these drugs are more commonly associated with FDEs, any introduction of a medication has the potential to result in a FDE. Metformin, a ...

Fixed drug eruption by etoricoxib confirmed by patch test*

Non-steroidal, anti-inflammatory drugs, followed by antibiotics, are the main causes of fixed drug eruption. They provoke one or several round erythematous or bullous lesions that recur in the same place after taking the causative medication. A positive patch test on residual, lesional skin can replace satisfactorily oral reintroduction. We describe the case of a 74-year-old woman with numerous...

Fixed Drug Eruption Induced by Levocetirizine

Fixed drug eruption induced by atenolol

Fixed drug eruption (FDE) is characterized by recurrent well-defined lesions in the same location each time the responsible drug is taken. We report here a case of multiple FDE induced by atenolol in a 48-year-old woman confirmed by positive patch test in previously affected sites. Beta-blockers-induced FDE are very rare. Only two cases had been reported in the literature. To the best of our kn...

Nimesulide-induced fixed drug eruption.

BACKGROUND Nimesulide is a cyclooxygenase (COX) inhibitor with a high degree of selectivity to COX-2. It is a widely used and well tolerated nonsteroidal antiinflammatory drug that also has analgesic and antipyretic properties. The most frequently reported side effects concern the gastrointestinal tract. Pruritus and skin rash are the most common cutaneous adverse reactions. There are only eigh...
