Final answer:
Furosemide is a diuretic medication used to treat hypertension and edema. Individuals with a history of Stevens-Johnson syndrome when taking sulfonamides should avoid furosemide due to the risk of allergic reactions. These individuals should also avoid thiazide diuretics and sulfonylurea-type oral hypoglycemic agents.
Step-by-step explanation:
Furosemide is a diuretic medication used to treat conditions such as hypertension and edema. It works by inhibiting the reabsorption of sodium (Na+) and chloride (Cl-) ions in the loop of Henle, increasing urine production and promoting fluid elimination from the body. However, individuals with a history of Stevens-Johnson syndrome when taking sulfonamides, which are chemically related to furosemide, are at risk for an allergic reaction to furosemide. It is important for these individuals to avoid furosemide, as well as thiazide diuretics and sulfonylurea-type oral hypoglycemic agents.
