I have been taking a certain name brand medication for awhile. Recently I moved and I got a new pharmacy (Walmart). What I have noticed is that these name brand pills are not the same. They are larger, they break easily and I've been getting headaches since I started taking them. I question the pharmacy if these pills were some knock off of the name brand. The lady became defensive and told me what they should look like... if they look like the picture... that must be that medication. All I know is... these are not the same pills I was taking for the past five years??? is it possible that the company changed them???
