how often can i take vitamin b12 injections Vitamin B12 Supplements and Injections

Injection Frequency : For patients requiring frequent B12 injections, using a thinner gauge needle (especially for SC injections) can reduce tissue trauma and discomfort over time

Numbness or tingling (often described as pins and needles) typically shows up in your hands and feet first

This makes it easier to ensure your B12 gets right into the muscle and not into the fat or lost somewhere in between

Call your health care provider immediately if you are experiencing any signs of an allergic reaction: skin rash, itching or hives, swelling of the face, lips, or tongue, blue tint to skin, chest tightness, pain, difficulty breathing, wheezing, dizziness, red, swollen painful area on the leg
