Blimey, they’re as like as chalk and cheese.
Tecfidera is easier to take, being a daily pill and having very few long lasting side effects. It also clears from your system fast so on the off chance it didn’t suit you, it’s easy to stop it and reverse any bad effects.
Lemtrada on the other hand has the benefit of being way more effective for most people. However, there’s some very nasty side effects and for some people has a worsening effect on their MS and disability. It also takes a long time to clear from your system, this is why it’s only given once a year for two years. Therefore it’s not so easy to repair any side effect damage.
I don’t think anyone can really properly advise you as it’s a big decision. The best thing would probably be to research both of them as well as you can. Look at potential effectiveness, expected side effects and read people’s experiences.
I’m on Tecfidera. I haven’t had terrible gastric effects as some have, but I have got ongoing problems with my lymphocytes. It’s not something that there are any experiential effects from, but it may cause me to have to stop the drug. I have no experience with Lemtrada, nor will I as I’m not a good candidate for it (partly because I’m nearly 19 years into MS, am really quite disabled, plus have had Graves’ disease previously which is one of the expected side effects).
However, if I were 15-20 years younger, were less disabled and weren’t ruled out because of previous thyroid disease, I would take the chance on Lemtrada. That’s just my opinion. Ask as many people for their thoughts, do as thorough research as possible, weigh up the pros and cons, then make your decision.
Best of luck. Sue
