MomPooja,
Doctor Vijay Ramanan in Pune is the expert on using thalidomide. He has had good success with many patients, but as is the case with all the drugs listed, some people cannot tolerate the drugs. With all the promise that Luspatercept had, for some people, it has not worked out. Some have good results and others don't and also have side effects they can't tolerate. If you have the opportunity to do it under an experienced doctor, thalidomide is worth trying, but as with all those drugs, the patient should be regularly monitored.
