Which category of medications is most prone to cause adverse drug reactions?

Insulins are indeed associated with a higher risk of adverse drug reactions, primarily due to their critical role in managing blood glucose levels in patients with diabetes. Insulin therapy requires precise dosing, and any imbalance can lead to significant consequences, such as hypoglycemia. The potential for adverse reactions increases with factors like the variability in patient response, the complexity of insulin regimens, and the risk of interactions with other medications.

In contrast, while antibiotics, analgesics, and antihypertensives can also cause adverse reactions, these classes typically have broader safety margins or more established monitoring guidelines that can mitigate these risks in many patients. Insulin’s impact on the body's metabolism and the immediate effects it can have if not managed correctly contribute to its higher propensity for adverse reactions, making it critical for prescribers to carefully monitor patients on insulin therapy.
