B12 levels A shot every 14 days not enough?

I have low B12 levels and have been receiving B12 shots every 14 days for the past 6 months and my latest blood tests show that my levels are still too low. I have the shots done by the nurse in my MD's office and she injects into my shoulder muscle. Has anyone else had this issue? Is there a different, more effective route? Now my MD wants me to get a shot every 10 days! What is going wrong?

Is there another way of getting B12 up?  Intravenous???

Does anyone have any idea why the shots are not working? Is there something else that might be interfering? Who would have a better idea on this than a GP? Or is everyone working with a GP for B12 shots?

Thanks Kiwi12 and blacky for your answers. Obviously I'm newbie! So far, the B12 deficiency is the only obvious result of the Crohns. In fact, my GP insisted that the gastroenterologist do the colonscopy that showed Crohns. He was convinced that I didn't have it prior to the colonscopy and did the colonoscopy because I am 49 and that is near the age that they recommend everyone have a colonsocopy.

Haha Robert!!! My hubby gives me shots at times too, always wondered about that sly grin of his:)

I too take B12 shots every 2 weeks. I think getting it more frequently should help your numbers rise. Hugs!

I am currently not on any meds, as I have only B12 deficiency as a symptom.  I need more info on options, as my current gastroenterologist is not extremely helpful.  His take was that no diet helps (just avoid any food that irritates) and that we have no way of knowing efficacy of meds without doing another colonoscopy, as I have no overt symptoms (so far). I would love to find a gastroenterologist who is more helpful but am unsure how to figure out who are the Crohns experts in my area (east of Seattle, WA)  so any ideas on how to figure that out would be appreciated.

In addition to the Crohns I am hypothyroid (even with thyroid supplementation, I am low energy, so I am also thinking I am under medicated for that, so am looking for an endocrinologist too!) and apparently also low vitamin D (see Seattle area- not exactly known for sunshine!)

Thanks for all your help!

Nearly a month ago, I was very weak, could not eat well (I don't eat any veggies or fruits - simply can't tolerate them) and my blood work was not ok, so I was but on B complex shots every other day for two weeks. The total was 12 injections. This week, I had another test and fatigue returned severer. I saw my doc yesterday and asked him about the frequency of taking the B shots. He told me that it should be once per month but since my blood work is not that good, I can take a shot every week.

As for self-injecting yourself, I learned to give myself an im injection. It has become ok for me as a lot of times I have to take 3 or 4 im injections a day (e.g., zofran /12 hrs, painkillers, MTX, etc...)and of course, I'm not going to go to my dr's office or a hospital several times a day. You will learn it quickly and get to know the correct sites of injection.

Hope you feel better soon:)
Take care!

I have had 2 resections and had an issue with B12 after my first resection.
(I am also 49)

Started taking sublingual B12 3 times a week. Also juicing once in a while when I can. (kale,cabbage,carrots,apple)

B12 blood tests are now on the high side.

I just started taking LDN and no other meds. So nothing to block B12.

Dr also has me on 50,000 IU twice a week vitD. You should get that checked as well.

NY Veggie it is by prescription only, I do know that. I was told that the oral version of B12 does give even the normal person enough of the vitamin. My doc said with taking it orally you only absorb about 2 %, but with the shots you get much more. Hugs!
