What does vitamin B12 do?
Vitamin B12 supports normal red blood cell formation and nerve function. Our service starts with an assessment of whether treatment is appropriate for you. Where indicated, B12 can be given by injection into a muscle, bypassing the digestive system.
When to seek advice
If you are concerned about low B12, the cause needs to be understood before choosing treatment. Persistent tiredness can have many causes. Symptoms, medical history and any relevant blood results help determine whether further investigation or GP review is needed.
- Review the reason you are considering B12 treatment
- Discuss relevant symptoms, medicines and blood results
- Agree treatment and follow-up according to clinical need
What to expect at your appointment
- Before a first injection, we discuss your health, current medicines, allergies and reason for seeking treatment. We may recommend testing or GP review first.
- If an injection is appropriate, administering it takes a few minutes. The full appointment includes assessment and advice.
- The clinic offers a four-injection course and individual injections. The prescriber decides the frequency and ongoing requirements for your circumstances.
Treatment and follow-up
The response and follow-up depend on the reason for treatment. Most people can resume normal activities afterwards, although temporary tenderness, redness, itching or swelling may occur at the injection site.
Suitability and risks
Side effects and allergic reactions are possible. Mention any cobalt allergy when discussing B12 medicines. Seek medical advice for persistent tiredness, numbness, balance changes or other new symptoms rather than delaying assessment.
