Is it common for a MS patient to experience weight loss while on Tecfidera ?
Weight loss is not common on Tecfidera unless you have persistent gastrointestinal side effects like lack of appetite, nausea, abdominal pain, cramping and diarrhea. Since these side effects tend to either go away after several weeks or the person stops taking the drug, weight loss tends to be minimal. That being said, I did have a very stoic patient who continued on Tecfidera for many months despite persistent gastrointestinal side effects and that individual lost a lot of weight.
