Hey, my sister has had problems with pills in the past and yesterday I was over her house b/c she has a sinus infection and I was taking care of her. I asked if she had been taking her antibiotics and she said no she would just get better on her own b/c they make her feel weird. I persuaded her to take some and asked if I could see the bottle. I was curious as to what type was perscribed to her and how many times daily she was supposed to take it. She refused to let me see the bottle under the arguement that she doesn't like people looking at her medicine.. the pill she took came off as odd to me. It was a solid blue pill, that shape and style but a little smaller, It looked like a pain killer or something. I also noticed a yellow warning strip on the side of the bottle. I'm just worried about her, are there any blue antibiotics that look like this? if so can I be provided links as I saw the pill but not up close.
