Deb:
There is a lot to take in at first. Reading and learning is your best defense. Keep in mind that you do not have to make any quick decisions. ITP is usually not an emergency unless there is bleeding involved. If your counts are in a safe range (over 20k or 30k), you're okay for the time being.
I never considered myself sick when counts were low. I was just a person with lower than normal platelets. I was more tired and the treatments made me feel bad, but life went on. I had the same side effects as you while on Prednisone. My thoughts were all over the place. I found that the trick was to not take myself too seriously and try to laugh at my moods and words. I discovered that everyone else laughed with me and it made things easier. I have some of the funniest work stories.
Back to treatments. There are no set rules as to order, but there are some that are usually saved for last. Most of the time, Prednisone is first. It can cause remission for some people. IVIG is another option used in the beginning, but it is mostly a temporary, expensive and time consuming band-aid. Some people have had success with Win-Rho. It can be used if you are RH+. It takes about an hour and if a person is responsive, can last a few weeks or months. Next come the second set of options. Rituxan, Decadron, Imuran and CellCept. Rituxan is given once a week for four weeks. The infusions take about 4 to 6 hours. It can be a great way to achieve remission and for most, has few side effects. It does sound scary, but most find it less eventful than IVIG. Decadron is a steroid more potent than Prednisone, but is only taken four days a month for six months (according to protocol - can be used less). Imuran and CellCept are not used often, but can cause remission. They are immunusuppressants, but do not have the side effects that Prednisone does. Then come the last resorts. N-Plate and Promacta are newer drugs. They generally do not cause remission and are considered maintenance drugs, meaning that counts normally only stay up as long as you take them. Last is splenectomy. It used to be a common treatment, but is getting less popular as time goes on. People are realizing that it doesn't always work and there are risks. It is not something you ever HAVE to do....it's a choice. Some people end up going that route down the line, but isn't something you should rush into.
The important thing is to know your options and discuss them with your doctor. If he is knowledgeable about ITP, he will be familiar with the options and have an open mind.
BTW - NO ONE likes Prednisone. You're not alone there!
