What is Tecfidera and how does it work
Tecfidera is an oral prescription medicine with nervous system protective and anti-inflammatory properties. Although the exact mechanism on how it works is unknown, Tecfidera has been shown to activate the body’s response to cellular damage in patients with multiple sclerosis. It prevents immune cells from attacking the central nervous system.
What does Tecfidera treat
Tecfidera is an oral medication used for treating adult patients with relapsing forms of multiple sclerosis (MS). Relapsing forms of multiple sclerosis are defined as having periods of worsening of function followed by periods of temporary improvement. Relapsing patients may develop new or previous symptoms such as loss of sensitivity, muscle weakness, numbness or tingling sensations.
How effective is Tecfidera
1234 patients with relapsing forms of multiple sclerosis were studied for 2 years. 27% of patients in the Tecfidera 240 mg twice daily group had a relapse after 2 years of treatment compared to 46% of patients in the placebo (dummy pill) group, a risk reduction of 49%. Fewer patients in the Tecfidera group developed new or newly enlarging lesions. Tecfidera 240 mg 3 times daily did not offer additional benefit over the 240 mg twice daily dose.
In another study 722 patients with relapsing forms of multiple sclerosis were studied. In the Tecfidera group, 80 patients compared to 145 patients in the placebo group experienced a relapse during the first year of treatment. Patients who were given Tecfidera had a 44% less chance of experiencing a relapse compared to patients who were given a placebo.
In both studies Tecfidera was more effective than taking a placebo in treating relapsing forms of multiple sclerosis.
The safety and effectiveness of Tecfidera in pregnancy and children under 18 years of age is not known.
