Yes, in most cases, your GP will recommend a blood test before starting B12 treatment. This is to confirm whether you have a vitamin B12 deficiency and to determine the severity. It ensures the injection is necessary and helps tailor the most appropriate treatment plan for your needs. In some situations, like a known history of deficiency or specific medical conditions, your doctor may proceed without testing – but generally, a blood test is the first step.

The frequency in which you will require B12 injections will depend on your individual health circumstances. Some people require an initial course of more frequent injections (e.g. weekly or fortnightly) to build up their levels, followed by maintenance doses every few months. Others may only need a short-term boost. Your doctor will create a personalised schedule based on the cause of your deficiency, how your body responds to treatment, and whether it’s a long-term or temporary issue.

Yes, B12 injections can be better than tables if you have absorption issues (like pernicious anaemia or gut conditions) or need a quicker result. Injections deliver B12 directly into your bloodstream, bypassing the digestive system, which makes them more effective in some cases. That said, high-dose oral supplements work well for many people too. Your GP will help you weigh up the pros and cons based on your symptoms, blood test results, and health history.

No, you cannot just book a B12 injection without a referral or an initial consultation. Our doctors will discuss your symptoms, medical history, and possibly recommend a blood test before administering the injection. This step is essential to ensure the treatment is safe and appropriate for your situation. Once confirmed, we can arrange your injection during the same visit or book it in shortly after.

Like most injections, the B12 injection is only mildly uncomfortable with most people describing it as a small pinch or brief stinging sensation. It’s typically administered into the muscle of the upper arm. The discomfort is minimal and over in seconds. If you’re feeling anxious, let your GP or nurse know – we’re happy to make the process as comfortable as possible.

The time it takes to feel better after a B12 injection will vary. However, many people start noticing improvements within a few days to a week. Increased energy, clearer thinking, improved mood, and reduced pins and needles are common benefits. However, if your deficiency was severe or long-standing, it may take longer for your body to fully recover. Your GP will monitor your progress and adjust your treatment if needed.

Yes, B12 injections are generally safe during pregnancy and breastfeeding, particularly if you have a diagnosed deficiency. In fact, maintaining healthy B12 levels is important for both your wellbeing and your baby’s development. However, you should always consult your GP or obstetrician before starting or continuing treatment to ensure it's right for your stage of pregnancy or lactation.
