Frequently Asked Questions
Do I need a confirmed B12 deficiency to book?
No, but your online consultation form will be reviewed by the prescriber to make sure the injection is appropriate for you. If your history suggests you need blood tests first, or that you should be seen by your GP rather than starting private injections, we will tell you. People with previous low B12 results, at-risk diets, or absorption issues are the most common groups who book with us.
How often should I have injections?
That is a question for the prescriber, based on your individual situation, any existing diagnosis, and whether you are already receiving B12 on the NHS. Some people have a short loading course followed by maintenance injections. Others book less frequently. We do not set a one-size timetable.
Can I have private injections alongside my NHS injections?
Yes, and this is a common reason people book. If your NHS schedule leaves gaps that feel too long, some patients choose to add private injections in between, with their GP's knowledge. We would always recommend keeping your GP informed so your care is joined up.
Does the injection hurt?
The injection itself is quick, given into the muscle of the upper arm with a fine needle. Most people describe a brief sting and some mild tenderness afterwards. If you are nervous about injections, let us know on the form or when you arrive, and we will take extra time with you.
Are there any reasons I should not have B12 injections?
There are some contraindications, including known allergy to cobalt or cobalamin, and a rare hereditary condition called Leber's optic atrophy. Pregnancy, breastfeeding, anticoagulant medication, and certain other health conditions all need to be reviewed by the prescriber before a decision is made. This is exactly what the consultation form is for.
Is this the same as getting B12 from my GP?
No. Your GP is the place for diagnosis, monitoring, and ongoing NHS treatment of B12 deficiency and related conditions. What we offer is private clinical supplementation, administered by a qualified practitioner under the authority of a prescriber. If you have not been diagnosed and your symptoms suggest deficiency, we will encourage you to see your GP as part of the process.
What happens if I feel unwell after an injection?
Side effects from hydroxocobalamin are uncommon and usually mild, including soreness at the injection site, headache, or mild nausea. You will be given clear aftercare information, and you can contact the clinic directly if anything concerns you. If symptoms are severe or you suspect an allergic reaction, you should contact NHS 111 or your GP without delay.
Can I bring someone with me?
Of course. You are welcome to bring a partner, friend, or family member, particularly if it is your first injection or you feel anxious. The clinic is calm, private, and set up to feel more like a considered treatment space than a medical room.
