## **Core Concept**
Dapagliflozin is a **sodium-glucose cotransporter 2 (SGLT2) inhibitor**, a class of medications used in the treatment of **type 2 diabetes mellitus**. SGLT2 inhibitors work by blocking the reabsorption of glucose in the kidneys, leading to increased urinary glucose excretion. This mechanism can lead to several side effects.

## **Why the Correct Answer is Right**
The correct answer involves understanding the side effects profile of dapagliflozin. Common side effects of SGLT2 inhibitors like dapagliflozin include **genital mycotic infections** (due to increased glucose in the urine), **polyuria** (increased urine production), and **hypoglycemia** (when used in combination with other antidiabetic drugs). Importantly, dapagliflozin can also cause **euglycemic diabetic ketoacidosis**, a serious condition that can occur even when blood glucose levels are not excessively high. Additionally, **increased risk of urinary tract infections** and **Fournier's gangrene** (a rare but serious condition) are noted.

## **Why Each Wrong Option is Incorrect**
- **Option A:** [Not provided, assuming a side effect not associated with dapagliflozin].
- **Option B:** [Not provided, assuming another side effect not associated with dapagliflozin].
- **Option C:** [Not provided, assuming a side effect not directly or commonly associated with dapagliflozin].

## **Clinical Pearl / High-Yield Fact**
A key clinical pearl for SGLT2 inhibitors like dapagliflozin is the **increased risk of genital mycotic infections**. Patients should be counseled about symptoms such as vulvovaginal itching, redness, and abnormal discharge. Another critical point is the risk of **euglycemic diabetic ketoacidosis**, which requires a high index of suspicion, especially during periods of stress or when patients miss meals.
