Can you get a rash from drinking Diet Coke?

While it's uncommon, some individuals may experience a rash or allergic reaction from consuming Diet Coke due to sensitivity to artificial sweeteners, such as Aspartame or sucralose, or other ingredients in the beverage. Additionally, some people may react to caffeine or carbonation. If you notice a rash after drinking Diet Coke, it's best to consult a healthcare professional to determine the cause.
