Many physicians adhere to the premise that some medications are basically bad, undesirable and, potentially, addictive. If we begin to look at medications for a number of medical disorders we could probably say the same thing about them. However, there has been a lot of unfavorable press regarding certain medications, such as the one you are taking, Klonopin, and for that reason the majority of physicians feel it shouldn't be used. This is unfortunate because, when used appropriately and not abused, it can be quite effective in calming symptoms.
Psychiatry and psychiatric disorders still fall within the realm of the great unknown and I would suggest that there are many reasons people become anxious. One may be a biological and genetic predisposition and the medication for that might be the one you are taking. In other words, the medication that works best for you probably should be the medication you receive especially since you are not abusing it.
Blood pressure medication is sometimes used to control anxiety because it has the ability to relax muscles which have an effect on the blood supply and can leave a person feeling calmer. It is often used for performance anxiety, but only during the performance and not taken on a regular basis. At least this is my understanding and, I do admit that I am not an M.D.
Each prescriber has their own favorite medications and this can present problems for patients who have been taking medications that have worked for them for years. No, changing doesn't make sense unless there is real danger in taking a medication.
I know this must have been difficult for you and I can understand how unpleasant these appointments could be. But you are a consumer and you are asking for a service and I believe you have a right to have your opinions heard and considered carefully.
