Stopping Tecfidera to get pregnant

Postby kelyce522 » Thu Nov 21, 2013 8:57 am

Hey all!

I am new to this forum, but have had MS since 2007. I started Tecfidera about 5 months ago, switching from Avonex. I have a call into my neuro at the moment (since Tuesday anyway) to talk to him about stopping my treatment to get pregnant one more time. What I am curious about is whether or not anyone has any idea on how long you need to be off of Tecfidera before trying to get pregnant.? I called the ActiveNurse line yesterday to get some idea, but they had no clue. I'm sure there hasn't been many if any studies on this stuff yet, but I'm hoping someone knows something! I stopped copaxone before to get pregnant and had to be off for 4 months before TTC. Thank you in advance for any advice or info you may have!

Just to let everyone know....I did speak to my Neuro today...turns out like it's like most other meds. They recommend stopping Tecfidera for 2 months before trying to get pregnant. Thanks to everyone who looked to see if they could help me out!

according to my source, the half life of dimethyl fumarate is only one hour.

What is your source? I have called the nurse help line for tecfidera and spoke with my neuro... The nurse line was no help, but my neuro stated to do the 2 month detox like all other meds.... My search online turned nothing up either, including the tecfidera FAQ page. I am very curious!! Thank you for you input!!

as an example...

"Metabolism

In humans, dimethyl fumarate is extensively metabolized by esterases, which are ubiquitous in the gastrointestinal tract, blood, and tissues, before it reaches the systemic circulation. Further metabolism of MMF occurs through the tricarboxylic acid (TCA) cycle, with no involvement of the cytochrome P450 (CYP) system. MMF, fumaric and citric acid, and glucose are the major metabolites in plasma.

Elimination

Exhalation of CO2 is the primary route of elimination, accounting for approximately 60% of the TECFIDERA dose. Renal and fecal elimination are minor routes of elimination, accounting for 16% and 1% of the dose respectively. Trace amounts of unchanged MMF were present in urine.

The terminal half-life of MMF is approximately 1 hour and no circulating MMF is present at 24 hours in the majority of individuals. Accumulation of MMF does not occur with multiple doses of TECFIDERA."

My neuro told me I only needed to wait a couple of days because it leaves the body so quickly. That's why you have to take two pills a day, it has a super short half life.
