MEDICATIONS- SIDE EFFECTS (tell me about it!)

So, here I am. Back again the same day. Just got off from work. The weather isbeing a total shit. After work I had to go to the A & P to get frozen spinach (for my mom's friend Halloween party) and I also had to dropped off one of my friends from work. She such a cool person. Anyways, I just got off my doctor's blog and I just wanted to comment once again on the side effects of the medications. One time my sister had this weird rash. It was all over her body. So, she decided to take this medication for it. (Don't know how to spell it- starts with B, it is pretty well known around). So, after she has taken it she went off to sleep. When she woke up she started to get this very weird side effects. She was so dizzy, she couldn't even walk straight. So, because of her dizziness she even had to go to the hospital and get stitches, which means that she like fainted, maybe that's the wrong word to use because my sister was aware of that something was totally wrong with her. She just dropped (like people in the movies sometimes do). When she dropped she hit her head against her desk. So see, tell me about it- the weird side effects of the medications that they may have on you.
