I saw in some replies you have prescribed : tab.flanzen-10mg,thrice daily for 3 days. tab.wysalone-5mg,thrice daily for 3 days. Are these safe to be taken by my brother as he is 19 yrs and will be 20 yrs next month... PLEASE HELP ASAP..he is currently suffering from some ulcers for a week now and it s painful for him and they are not reducing even after 1 week Note : He has server gastric history and also,everytime he gets fever normal paracetomols don t work for him and he needs very high power antibiotics(like 600-650mg) to bring his fever down.
