Allegra (fexofenadine) allergy: I am not quite sure of the question. Allegra (fexofenadine) is a non drowsy antihistamine to treat symptoms of allergic or non allergic rhinitis. The symptoms include runny stuffy nose, sneezing, itchy and watery eyes. It can also help itching of the skin.
Canned and cooked tomatoes will contain significantly less MSM per serving. Corn may contain as much as 0.11 ppm, or 0.11 milligram per liter, of MSM. That's less than foods like coffee, which has an MSM concentration of 1.6 ppm, and Swiss chard, with about 0.2 ppm, but more than alfalfa, which contains only 0.07 ppm. It does contain biotin, but not much: 0.06 microgram in a 1/2-cup serving of canned whole corn.
What is MSM? Methylsulfonylmethane which is commonly known as MSM is a sulfur compound that naturally occurs and it is also a nutritional component found in a lot of food. It can be found in the normal diets of humans but the compound has become a popular dietary supplement.
