IV Therapy vs B12 Injections in Worthing: What’s the Difference?
IV therapy and B12 injections are sometimes grouped together, but they are different services with different routes of administration.
Published by Aesthetics Worthing · 18 September 2026
The basic difference
IV therapy delivers fluid through a vein. A B12 injection is given into a muscle. They are not interchangeable simply because both may involve vitamins.
What happens before treatment?
Suitability should be discussed before either service. Your health history, reason for considering treatment and any relevant concerns need to be considered. If tiredness or another symptom needs medical investigation, speak to your GP rather than relying on a wellness treatment to diagnose or treat the cause.
Which should I choose?
There is no single answer based only on a search term or symptom. The appropriate starting point depends on why you are considering treatment and whether it is suitable for you.

Does a B12 IV mean the same thing as a B12 shot?
No. B12 IV is listed on the IV therapy menu, while the B12 Shot is an intramuscular appointment. When enquiring, say whether you mean a shot or an infusion so the clinic can explain the correct appointment and price. Do not assume that one service can be substituted for the other.
Diagnosed deficiency and a wellness enquiry are different
If you have a diagnosed B12 deficiency, follow the treatment plan from your GP or treating clinician. NHS information explains that treatment depends on the cause of deficiency. A private wellness appointment should not replace that assessment or change an existing prescribed plan.
If tiredness is persistent or unexplained, start with medical advice. Neither a B12 shot nor an IV drip is a guaranteed way to feel more energetic.
Questions to ask before deciding
Ask which preparation or formulation is being considered, why it is relevant to you, what risks and aftercare apply, how long to allow for the appointment and whether any further assessment is needed. Tell the clinic about medicines, supplements, allergies and previous reactions.
