What are potential side effects of Bactrim that healthcare providers should monitor for?

Bactrim, which contains trimethoprim and sulfamethoxazole, is associated with several serious side effects that healthcare providers need to monitor for. One significant risk is Stevens-Johnson syndrome, a severe skin reaction that can lead to blistering and peeling of the skin, requiring immediate medical intervention. Additionally, Bactrim can cause electrolyte abnormalities, particularly hyperkalemia (elevated potassium levels) and hyponatremia (low sodium levels), which can have serious cardiovascular implications if not addressed promptly.

Monitoring these side effects is critical because Stevens-Johnson syndrome can progress quickly and can be life-threatening, while electrolyte imbalances can lead to complications such as cardiac arrhythmias. Recognizing and managing these potential issues early can lead to better patient outcomes.

While the other options contain possible side effects of Bactrim, they are typically less severe or not as specific as the risks associated with Stevens-Johnson syndrome and electrolyte disturbances.
