This drug made me terribly ill and I will refuse to take it if it is ever prescribed again. I had to take 3 a day during which I became so ill that I cut the dosage down to 1/2 pill which I found I could tolerate. I had a UTI which became MRSA. I'd rather have MRSA. I could have been depressed or had headaches. I was so nauseated, I wouldn't know.
