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.
Most fruits also contain MSM, but no sulfur from cysteine or methionine, because there is hardly any protein in fruits. MSM has also been found in tea, coffee, beer and port wines. It is not easy to determine sulfur content in foods because the amounts depend greatly on the quality of soil and farming practices.
Methylsulfonylmethane is a relatively new dietary supplement form of sulfur that is found in our living tissues. MSM supports healthy connective tissues like tendons, ligaments, and muscle. Thus, it is important in conditions such as arthritis, muscle pains, bursitis, etc.
