How quickly will I feel better?

Many people notice improvement within a few days once treatment starts. Full recovery can take longer and depends on the cause and how low levels were.

How often are injections needed?

Your schedule depends on the cause of deficiency. Some start with frequent doses then move to maintenance every two to three months if absorption is a problem.

Are there side effects?

A sore arm, redness or itching near the injection site are common and usually mild. Serious allergic reactions are very rare, but seek urgent help if you feel unwell.

Can I have this if I am pregnant or breastfeeding?

Treatment is often recommended when deficiency is confirmed. Tell us if you are pregnant or breastfeeding so advice can be tailored to you.

Do I need tablets or injections?

Tablets may suit diet related deficiency when absorption is normal. Injections are used when your body cannot absorb B12 well or symptoms are significant.

Can I drive or go back to work after?

Yes, most people can return to normal activities straight away. If you feel light headed, rest in the pharmacy until you feel better.

Vitamin B12 made clear

Vitamin B12 helps your body make red blood cells and keep nerves healthy. Low levels can cause tiredness, breathlessness, pale skin and mouth ulcers. Injections are used when tablets are not suitable or deficiency is severe or ongoing.

Hydroxocobalamin is the preferred injection in the UK. A typical plan starts with frequent doses to build levels, then regular maintenance. People with pernicious anaemia often need ongoing injections. Dietary deficiency may need fewer injections once levels recover.

At South Ealing Pharmacy your trained pharmacist gives the injection into a muscle in your upper arm or hip. It is quick. You may feel a small sting. Most people can go back to normal activities straight after.

Common effects include soreness, itch or redness at the site. Serious reactions are very rare. Tell us about medicines, allergies, pregnancy or breastfeeding. Bring any blood test results so we can tailor your plan and share updates with your GP.
