Is any cortisone cream that is stronger than 1 percent available over the counter in the US?

No, in the United States, over-the-counter (OTC) cortisone creams are typically limited to a strength of 1 percent or lower. Higher concentrations, such as 2.5 percent or more, require a prescription from a healthcare provider. It's important to consult with a doctor for appropriate treatment options if stronger corticosteroids are needed.
