An infusion appointment can look straightforward: choose a treatment, select a time and attend the clinic. But IV therapy involves intravenous access, clinical assessment and, in some cases, prescription-only medicines. The best questions before booking infusion therapy help you understand whether the treatment is appropriate for you, what it contains, and whether the provider has the governance needed to deliver care safely.
For people seeking support with fatigue, recovery, hydration or wellbeing, it is reasonable to want clear answers before making a decision. A responsible clinic should welcome those questions, allow time for informed consent and be prepared to explain the limits of what an infusion can realistically achieve.
The best questions before booking infusion therapy
1. Is this infusion clinically suitable for me?
Start with your individual circumstances, not the treatment menu. Ask whether the proposed infusion is suitable in light of your medical history, current symptoms, allergies, pregnancy or breastfeeding status, and any medicines or supplements you take.
This matters because intravenous treatment is not automatically appropriate simply because an ingredient is commonly used in wellness settings. Kidney or heart conditions, certain metabolic disorders, a history of adverse reactions and fluid restrictions may change the risk profile. A clinician should also consider whether new, persistent or severe symptoms need assessment through your GP, NHS 111 or urgent care rather than an elective infusion.
A proper answer should involve questions about you. A generic reassurance, without a meaningful consultation or medical screening, does not provide the individual assessment this decision requires.
2. What is in the infusion, at what dose, and why?
Ask for the full formulation in plain language, including the fluids, vitamins, minerals, medicines or other ingredients, along with their doses. You should understand the stated rationale for each component and whether there is a clinical reason for the combination in your case.
This is particularly relevant for high-dose vitamin infusions and NAD+ treatments, where the likely effects, practical experience and evidence base can differ considerably from routine treatment of a diagnosed deficiency. More ingredients do not necessarily mean greater benefit. In some circumstances, a simpler formulation may be more appropriate, while in others an infusion may not be needed at all.
The clinician should distinguish clearly between treating a confirmed deficiency or clinical condition and supporting general wellbeing. They should not present IV therapy as a substitute for diagnosis, a balanced diet, adequate rest, mental health care or treatment prescribed by your usual healthcare team.
3. What evidence supports this treatment for my goal?
Ask what evidence supports the proposed treatment for the outcome you are seeking. The most useful response is specific: it explains the strength and limitations of the available evidence, rather than relying on testimonials or broad claims about energy, immunity, detoxification or longevity.
Evidence is often stronger when IV treatment is used for a defined medical indication under appropriate clinical supervision. For wellness goals, evidence may be more limited, mixed or dependent on whether an underlying deficiency has been identified. This does not mean every elective infusion is inappropriate, but it does mean expectations should be proportionate.
If you are mainly concerned about tiredness, for example, ask whether blood tests, lifestyle factors, sleep, stress, medication effects or an underlying health condition should be considered first. A well-run service will recognise when investigation or referral is the better next step.
4. Who will assess me and administer the infusion?
Ask who will carry out the consultation, who will insert the cannula and who will remain responsible for your care during the appointment. Their role, professional registration and relevant experience should be explained clearly.
In the UK, the appropriate professional background can vary according to the service and treatment provided. What matters is that the practitioner works within their scope of practice, has relevant IV competency and is supported by clear clinical governance. Where prescription-only medicines are involved, ask how prescribing decisions are made and which appropriately qualified prescriber is accountable.
It is also sensible to ask whether the consultation is carried out by the person making the treatment recommendation or whether there is a documented clinical review process. Accountability should never be vague.
5. What checks take place before treatment begins?
A pre-treatment check should be more than a booking form. Ask how the clinic verifies your identity, confirms the planned formulation, reviews allergies and checks relevant observations or test results where indicated.
The exact checks depend on the infusion and your health status. Some treatments may require laboratory results, a medication review or confirmation of hydration status. For others, a detailed clinical history may be the most relevant safeguard. The key question is whether the assessment is tailored to the actual risks of the treatment.
You can also ask how often your suitability will be reviewed if you are considering repeat appointments. A recommendation made months ago may not remain appropriate after a new diagnosis, medication change or significant change in symptoms.
6. What are the common side effects and the serious risks?
Every intravenous procedure carries some risk. Ask about common effects such as discomfort at the cannula site, bruising, temporary flushing, nausea, headache or changes in how you feel during the infusion. Then ask what more serious complications, although less common, the clinic is prepared to recognise and manage.
Relevant risks may include irritation or inflammation of the vein, leakage of fluid into surrounding tissue, infection, allergic reactions and fluid or electrolyte complications. The significance of each risk depends on the ingredients, dose, infusion rate and your clinical history.
A clear explanation of risk is not intended to alarm you. It is part of valid consent. You should be told what symptoms to report during treatment, what to do if you feel unwell after leaving, and when to seek urgent medical attention.
7. What happens if I have a reaction or become unwell?
Ask about the clinic’s emergency arrangements before you attend. A responsible provider should be able to explain how staff monitor patients, what emergency equipment and medicines are available, how adverse events are documented, and when escalation to emergency services is required.
The answer should be practical rather than aspirational. For example, ask whether you will be observed during the infusion, whether a trained clinician is immediately available, and what happens if you develop symptoms after the appointment. This is especially important if you have a history of allergies, anxiety around needles or a medical condition that may complicate treatment.
You may also wish to ask whether the clinic shares relevant information with your GP, with your consent, when this would support continuity of care.
8. How are medicines, products and infection-control procedures managed?
Ask how the clinic sources, stores and checks the products it uses. You do not need technical detail on every process, but you should receive reassurance that medicines and other clinical products are handled through appropriate supply arrangements, stored according to requirements and checked before administration.
Infection prevention is equally central. Ask about hand hygiene, skin preparation, single-use equipment, sharps disposal and the process for maintaining a clean clinical environment. These procedures are fundamental to IV safety, not optional extras.
For clinic operators, transparent protocols, staff training records, incident reporting and regular audit provide the practical foundations of this assurance. For patients, the visible signs are a clean setting, unhurried checks and staff who explain what they are doing.
9. What will it cost, and is there pressure to book a course?
Ask for the full price before committing, including consultation fees, blood tests, prescribed medicines, follow-up and any cancellation charges. It should be clear whether a treatment plan is based on a documented clinical need or a commercial package.
Repeat infusions may be appropriate in limited circumstances, but the frequency should be explained and reviewed rather than assumed. Be cautious of pressure to purchase multiple appointments before you have had the opportunity to assess tolerability, benefit and ongoing suitability.
You are entitled to time to consider the information. Good consent is a process, not a signature collected while you are deciding at the reception desk.
Bring your health information to the consultation
A short preparation can make your consultation more useful. Take an up-to-date list of medicines and supplements, recent test results if relevant, details of allergies and previous reactions, and a clear description of the symptom or goal that has led you to consider treatment. If you have received advice from your GP or a specialist, mention it.
The right provider will treat your questions as part of safe care, not as an obstacle to booking. The most reassuring answer is often not a promise of dramatic results, but a measured explanation of what is appropriate, what is uncertain and what support is available if your needs change.
