Vitamin B12 Injection

You may need an injection if you have symptoms such as fatigue, pins and needles, or memory issues. A simple blood test can confirm low B12 levels. If you have gut conditions or surgery affecting absorption, your GP may recommend injections over tablets. Discuss your symptoms and test results with our pharmacist for personalised advice.

Most patients describe only mild discomfort during the injection. Our pharmacists use fine needles and proper technique to minimise pain. The site is cleaned, and the injection takes only seconds. You may feel slight soreness for a day, but many report no lasting discomfort.

Many patients notice improved energy and mood within 48 to 72 hours of their first injection. Some benefits, like reduced pins and needles, can take several days. Complete restoration of B12 stores may require a course of injections over a few weeks.

Yes. The injection has no sedative effects. You can drive, return to work or resume normal activities immediately after your appointment.

Side effects are rare. You might experience mild redness or soreness at the injection site. In very rare cases, some people report itching or an allergic reaction. Our pharmacist will monitor you briefly after your injection and advise if any further action is needed.

Initial treatment usually involves injections every other day for two weeks. Once your levels improve, most patients need maintenance injections every three months. Your pharmacist will recommend a schedule based on your blood tests and symptoms.
