I believe that they generally start you out at ten. But I could be wrong. I would discuss this with the doctor to get good answers. You may be sensitive to it. But it usually takes a week or two for side effects to go away. I would try to take it as doctor recommended and be patient. If the side effects don't subside after two weeks, then I would discuss with the doctor about changing the medication.
I hope that this helps.
