Hi Susan,
Go to www.wikipedia.org , type in American Medical Association in the search engine. You will then get the medical page, type in your medication and hit go, if you are looking for Antivan type in Lorazepam and a table of contents will show , pick which section you want to read, I suggest you read the chapter on withdrawl. You can check any medical conditions from this site it is a very good site. Good luck to you I have a bipolar 14 year old son who takes serequel, I have PTSD and take lorazepam wich is generic for Antivan. I have personaly benifited from the information providid at this site. vlbhopes
