What pill has TEC on it and what is it?

A pill marked with "TEC" is identified as Tecfidera, which contains the active ingredient dimethyl fumarate. It is primarily used to treat relapsing forms of multiple sclerosis (MS) by reducing the frequency of MS flare-ups. Tecfidera works by modulating the immune system and has anti-inflammatory properties. Always consult a healthcare professional for accurate identification and information about medications.
