2 weeks into to Tecfidera

I’ve been taking Tecfidera for nearly 2 weeks now and so far I have been fine, no side effects whatsoever. Until today - I’ve had horrible diarrhoea all day to the point even sipping water is making me need to rush to the loo. Is it normal for side effects to start after a couple of weeks or is this coincidence and I’ve caught a tummy bug? I feel absolutely rotten at the moment so hoping it doesn’t continue for long 😩

I found the Tecfidera side effect to be limited to hot flashes and the odd itchiness. Doesn't happen very often, and I find taking them with a snack helps. It sounds like you might have picked up a bug.

Sorry you're feeling rubbish! When I started tecfidera my MS nurse said side effects appear for some people in the 3rd or 4th week and should pass. It could just be a bug like you say though, as it sounds quite severe.
