Bayer HealthCare Pharmaceuticals Inc. has come up with a new 30-gauge needle, Betaseron (interferon beta-1b), its treatment for relapsing forms of multiple sclerosis (MS). It will be the thinnest needle (as thin as for insulin and pediatric injections) of any injectable therapy for MS patients. This will tackle the injection anxiety that many MS patients face during the treatment. They will now be more comfortable taking injections. The new needle causes lesser pain.
