Other times, there could be some other overt problem or disease which is making it necessary for you take them. Whatever the cause that you have taken these shots, it is highly irregular for you to have such dark urine. Sometimes, it is normal to have deep yellow or even orange urine as a result of taking this particular vitamin, you should also know sometimes, this irregularity of urination can last for up to a week or even more. However, it is practically unheard of to have dark colored urine that is so dark that you might mistake it for blood after taking this shot. While there are several obvious and pretty clear cut side effects of taking a vitamin B 12 injection, dark red to brown urination is certainly not one of them.

Your best bet in this case is to consult with the doctor who has prescribed that you take these shots in the first place. The doctor will be able to give you a better idea about whether there is any relation between the shots and your urine color. Among the other side effects of taking this particular injection or series of injections, the most prominent one is mild diarrhea and heart palpitations, accompanied with a feeling of uneasiness. This is the commonest side effect and even this does not manifest itself strongly enough to really affect you for any significant length of time.

To repeat, it is better you check with the doctor who prescribed the shots for a more accurate picture.
