BACKGROUND: Anaphylactic reactions to @entity799 are often ascribed to the @entity207 component of this antibacterial drug. OBJECTIVE: To determine whether the @entity206 component can be the cause of an anaphylactic reaction. METHODS: An analysis was made of reports on @entity2021 attributed to @entity206 , as notified to the Drug Safety Unit of the Dutch Inspectorate for Health Care. RESULTS: In the period between September 1981 and November 1995, 13 such reports were received. Nine were classified as probable @entity2021 . Of these, the causal relationship between exposure to @entity206 and @entity2021 was classified as definite in three reports, and as probable in the other six. The remaining four reports were classified as possible @entity2021 . In one of these, the causal relationship was classified as definite, and in three as probable. CONCLUSION: Although @entity2021 due to @entity206 seems to be rare, it may be more common than previously thought. Apparently, @entity2021 to @entity799 is not always caused by @entity207 .
