Which of the following is NOT a common triggering agent for Steven-Johnson Syndrome and TEN?

Steven-Johnson Syndrome (SJS) and Toxic Epidermal Necrolysis (TEN) are severe skin reactions that can be triggered by various medications and other factors. The correct answer highlights vitamin D supplements as not being a common triggering agent for these conditions.

Anticonvulsants and barbiturates are well-documented triggers for SJS/TEN. Medications in these classes are known to cause adverse hypersensitivity reactions, leading to the skin manifestations associated with these syndromes. Similarly, nonsteroidal anti-inflammatory drugs (NSAIDs), including naproxen, have also been implicated in cases of SJS/TEN, although they are less commonly associated than the previously mentioned drug classes.

In contrast, vitamin D supplements are generally considered safe and do not have a notable association with SJS or TEN. While it is important to monitor all medications for potential side effects, the evidence surrounding vitamin D supplements does not support them as a significant risk factor for these severe skin reactions. Therefore, the choice of vitamin D supplements is correct as the outlier in this context.
