WATERLOO PHARMACY & TRAVEL CLINIC
Vitamin B12 Injection Service
Clinically guided Vitamin B12 injections from Waterloo Pharmacy. Our service starts with a clinical assessment to check whether a B12 injection is appropriate for you.
Why is Vitamin B12 important?
Vitamin B12 deficiency can be associated with tiredness, weakness, changes in sensation, memory or concentration difficulties and anaemia. Symptoms can occur even without anaemia, so proper assessment is important.
Who may be at risk of B12 deficiency?
- People with low dietary B12 intake
- People with conditions affecting B12 absorption
- People with pernicious anaemia
- People who have had certain gastrointestinal conditions or surgery
- People taking some medicines, including long-term metformin or proton pump inhibitors
Your pharmacist will discuss your circumstances and advise whether further assessment or referral is needed.
Our Vitamin B12 Injection Service
Where appropriate, hydroxocobalamin may be administered by intramuscular injection following your clinical assessment.
The treatment schedule depends on the cause of deficiency and your individual circumstances.
Six injections where clinically appropriate
For adults with confirmed B12 deficiency without neurological involvement, hydroxocobalamin may be given as:
1 mg by intramuscular injection, three times a week for two weeks.
Individual treatment plan
Some people may need ongoing B12 injections, while others may be suitable for oral supplementation or less frequent treatment.
The frequency depends on the underlying cause of deficiency and your individual needs.

Before your injection

- Possible causes of deficiency
- Whether further testing or referral is appropriate
Important
A B12 injection is not a substitute for investigating unexplained symptoms.
If you have numbness, tingling, weakness, balance problems or other neurological symptoms, you may need further medical assessment.
How quickly will I feel a difference?
Hydroxocobalamin starts working straight away, but it can take days or weeks for symptoms to improve. How quickly you respond depends on the cause and severity of the deficiency.
Is the injection safe?
Hydroxocobalamin is an established treatment for vitamin B12 deficiency. As with any medicine or injection, side effects can occur.
- Pain, swelling or itching at the injection site
- Nausea or diarrhoea
- Headache or dizziness
- Skin reactions
Your pharmacist will discuss relevant risks with you before treatment.
