Robby is right. The doctor can best advise you on what your options are. In my case, we found that oral tabs were not effective and caused too much fluctuation in my hormone levels. I was PMSing every day. We switched to patches and that smoothed things out so I wasn't on a daily roller coaster. However, after over four years of constantly adding more patches, my labs showed that my hormone levels never reached optimum levels. At my last appointment, we discussed this at length and decided to switch to injections once per week. I start those next week, so I have no idea if they will be better or not. Doctors tend to make injections a last resort due to the possibility of infection and other issues. There are quite a few ladies here who are on the injection route and have good results, so I am hopeful.
As Robby stated, be open and honest with your doctor. Don't downplay your symptoms, and don't exaggerate them either. They need to be able to gauge how you are responding to current and past meds and dosages.
Good luck!
