question: My daughter is twenty six now and since she was seventeen she had complained about tightening in her chest. It has gotten worst now and she experience it more often. Today she went to emergency room and told docs exactly what i advised her and how her fathers family have had major heart problems. They looked all over that and prescribed her cetirizine and she has never had any allergy problems. I am so upset cause what do tightening of the chest has to do with allergies. then i just finished reading actual people comments about this drug and the horrible side effects all of them experienced. then to top it off i see that three of those side effects is tightening of the chest, fast or irregular heartbeak and muscle weakness. The same thing she went in for. I am no nurse but I have worked in the medical field and seen alot and heard alot. Where are the true docs that really care and dont throw anykind of meds around like candy. especially if it don t fit the diagnosis. Just tired of worry about some docs telling the truth and worried about my daughter and her precious children health. Wish I could of gotten a free caring answer but once again its proven that nothing in life is free! Sorry but cant sorry to waste your time and mine! In the future do something free for those in need it would greatly be appreciated by those in need and by GOD. God Bless!
