B12 injections

Hi Rhiannon231,

Just had fourth b12 today. My first jab was extremely painful and was passing out. Nurse had not known this to happen before. It took a few days to get over it, and was so latholgic more than normal. Still very tired but told it takes awhile sometimes to work, slight improvement with my hands though, not so much tingling. So it's a case of patience.

And try not to worry.

Hi, yes it is. It will take time for it to kick in. It took till my 5th injection to start feeling better. Rest and look after yourself.

hi Rhiannaon. often the symptoms exacerbate temporarily before they start to resolve post the first few injections. it's the body way of adjusting itself to the b12. nerves and cells get woken up and kicked into action. also, if you are 'sensitive' that readjustment will be more marked.

Hello, I've had to have the loading doses twice now and for the 2 weeks I'm having them I just feel awful. I t's like all my symptoms get a lot worse. I read that high doses of b12 can deplete yoyr potassium, iron and folate levels so I've been taking a multi-vitamin tablet with iron and folic acid and eating a banana just after my injection which definitely does help me. If I feel myself becoming tired and a horrible like brain-fog I'll eat another banana.

I had my last injection on friday and today was my first day off work, I slept until 12pm today and then half an hour later I fell asleep on my sofa until 4pm!! Now I feel loads better and my head feels clearer, weirdly I still feel tired but that awful exhausted/confused feeling has gone.

It took around a month for me to feel "normal" again last time and people were commenting on how well I looked. But I suppose it depends on how low your levels were and how long they've been low.

It's going to be a horrible couple of weeks but it will be so much better after the injections finish! Good luck!

Hello Rhiannon231,

When I started on this discussion I too had just started my loading doses and was very eager to see results. Everybody on here was so kind and tried to tell me that it takes time and a lot of patience. I am now 1 month from my last injection and things ARE better, I still feel tired, but maybe not so much, and my other symptoms have improved ,so I do see what I was told in the beginning, it takes a long time, look after yourself and rest as much as you can, and the ladies said "be kind to yourself" and I pass this advice on and hope you do feel improvement soon. I am not qualified to give advice on folates etc., but a lot of people on here are. Best wishes.

Thank you all, I'm so glad that it's normal to feel the way in feeling now!! I've got my second injection today so I guess it will be another early night for me 😴

So, you can see that yes - it's normal to feel worse but there's a light at the end of the tunnel!  I was still feeling rough at three weeks and the nurse told me it's going to take six weeks to really feel better...that helped me. I had the same exhaustion, forgetfullness and nerve symptoms - sometimes better, sometimes worse.  I can see an overall improvement, though. You will, too!

Thank you all, it's encouraging to know that I'm not alone and there will be a good result! I've had my second injection today and ready for bed at 7.30pm!!
