Hello Helen,   Unfortunately there are only a few people qualified to answer many of the drug questions, and they all have day jobs. Answering questions here is something these doctors do in their spare time. Also something we are currently working on making more clear is that the Q&A space is for general health questions. It is actually illegal to diagnose a problem or condition over the internet. In an ideal world we would answer every question with in minutes of it being asked but we are still working on recruiting new experts to help us out. The Q&A section was just started in April so we are still working out the kinks. Im very sorry we weren't able to answer your questions in a timely manner.   I hope this was helpful. sorry about the delay in getting back to you.
