Could a rapidly spreading, highly pruritic rash on both legs, which initially resembled insect bites but has evolved into numerous irregular lesions, be an adverse reaction to taking an antacid like Digene, or is it potentially linked to the underlying gastrointestinal condition?
While an allergic reaction to an antacid like Digene (which contains aluminum and magnesium hydroxide) is possible, it is relatively rare. Sometimes, certain gastrointestinal conditions, such as inflammatory bowel diseases, can be directly linked to skin lesions on the legs. Another possibility is a hypersensitivity reaction to actual insect bites or an infection. Because this rash is spreading quickly, I highly recommend consulting a healthcare professional or a dermatologist promptly.
