I have to say that it is normal for many people with anxiety to experience an increase in anxiety when starting a new medication or altering the level of a medication they have been taking. In part it is because the new dosage may be causing some alterations in the body, and in part because the the person involved is understandably anxious about the change. Will it be successful? Will it cause unwanted side-effects? Will it be a flop like other meds in the past? There are many unanswered questions.

Give the med some time - a few weeks, if possible - then you can decide if it is beneficial for you.
