Background: Following a drug eruption, patients and their doctors need to know which drugs can be safely administered for subsequent illnesses. Currently available laboratory tests are unable to answer this question in a clinically meaningful manner. Aims: To describe our use of oral provocation tests to provide a list of safe drugs to patients. Methods: We studied the records of 100 patients who underwent oral provocation testing in our department between 2003 and 2009. All patients were admitted to hospital and drugs were administered under supervision, one drug per day. A dermatologist evaluated all symptoms and signs that developed following drug intake. Results: Sixty nine women and 31 men underwent provocation testing. There were 96 reactions in 61 patients, of which 44 reactions in 34 patients were judged to be true reactions. All reactions could be controlled, with treatment or spontaneously. A list of safe drugs was provided to the patient along with written instructions to avoid any drug(s) that had produced a reaction. Conclusions: Oral provocation tests are safe and effective in providing patients with a list of drugs they can take safely. These tests should preferably be undertaken after admitting the patient to hospital.
