Hello there,
The therapeutic range is a statistical concept: it is the concentration range associated with therapeutic response in the majority of patients. Consequently, some patients will exhibit such a response at serum levels below the lower limit of the range, while others will require serum levels exceeding the upper limit for therapeutic benefit.
When using AD's some people will do well on a lower dose and others need to be at the higher end to find the drug to be effective.
By slowly increasing the medication you should find a dose that helps you to feel the best you can. However, due to the lag time of the AD meds being fully effective both the dose and the time on the drug factor into when you will begin to be at the right dose to best meet your needs.
If you are noticing an improvement that is a good sign. You may need another med added to help with the anxiety. A good one is Buspar for many people.
Keep on talking with us.
Gentle Hugs
