"Is IV therapy safe?"
It's the single most common question I get - over WhatsApp, on Instagram, in person while I'm setting up at someone's kitchen table. And honestly? The fact that you're asking it puts you ahead of about 80% of the people who book IV drips without a second thought.
Because here's the thing: IV therapy is safe. But that sentence needs about six qualifiers attached to it, and most providers would rather you didn't ask about them. I'd rather you did.
I'm Chloé Nefdt, a SANC-registered Professional Nurse and the founder of IVgo - Cape Town's mobile IV therapy, NAD+ and peptide service. I've administered thousands of drips. I've also turned away clients who weren't suitable candidates, and I've fielded panicked messages from people who'd had bad experiences with other providers. Both of those things inform what follows.
This is the honest, evidence-based answer to whether IV therapy is safe - including the parts the marketing brochures leave out.
The Short Answer
Yes - when administered by a qualified healthcare professional, with proper health screening, using sterile equipment and medical-grade ingredients.
That's the short answer, and it's true. Intravenous therapy has been a cornerstone of medicine for decades. Hospitals administer millions of IV infusions every year. The technique is well-understood, the pharmacology is established, and the safety profile, when protocols are followed, is excellent.
A 2020 systematic review by Suh et al. in Nutrients examining high-dose intravenous vitamin C therapy found that adverse events were predominantly mild and transient when administered in controlled clinical settings with appropriate patient screening. The same pattern holds across the broader IV vitamin therapy literature: the therapy itself isn't the risk variable. The administration is.
That distinction matters. Because IV therapy delivered by a registered nurse with proper screening is a fundamentally different proposition from IV therapy delivered by a "wellness technician" in a pop-up lounge with a WhatsApp booking system.
Common Side Effects (Minor and Transient)
Let's get the everyday stuff out of the way. These are the side effects that occur with some regularity and are considered clinically unremarkable:
Bruising at the cannulation site. This is the most common side effect of any IV procedure - not just vitamin drips. A cannula goes into a vein, and sometimes the surrounding tissue bruises. It's cosmetic, painless within a day or two, and completely harmless. If you bruise easily (thin skin, blood thinners, or just genetic predisposition), you'll likely see a small mark. It fades.
Mild discomfort during cannulation. The needle part. Nobody loves it, but it takes seconds. A skilled nurse with good vein selection makes this as painless as possible - but it's still a needle, and I won't pretend otherwise. If you're particularly needle-averse, I cover that in the FAQ below.
Coldness or a cool sensation in the arm. IV fluids are typically stored at room temperature, which is cooler than your body temperature (37°C). When room-temp saline enters your bloodstream, you might feel a cool sensation travelling up your arm or through your chest. It's odd the first time, but it's completely normal. Some providers warm their fluids; I do when the situation warrants it.
Occasional dizziness or lightheadedness. More common in clients who haven't eaten before their appointment or who are already dehydrated. Your blood pressure can dip slightly during infusion, particularly if you're sitting upright and haven't had enough fluids beforehand. Eating a meal and drinking water before your drip solves this in most cases.
Mild nausea. Occasionally reported, particularly with drips that contain higher concentrations of certain B vitamins or minerals. It's usually transient and resolves during or shortly after the infusion.
Here's the important context: none of these are dangerous. They're the same side effects you'd encounter from a blood draw or an IV line in hospital. They resolve on their own, they require no medical intervention, and they don't indicate that anything has gone wrong.
Rare but Serious Risks
Every medical procedure carries risk, and IV therapy is no exception. These are the serious adverse events - they're rare, but you should know about them.
Infection. Any time the skin barrier is broken, there's a theoretical risk of introducing bacteria into the bloodstream. In practice, this risk is extremely low when proper aseptic technique is followed - gloves, skin disinfection, sterile single-use cannulas, and a clean working environment. The risk increases significantly with reused equipment, poor hand hygiene, or non-sterile environments. Mermel (2017) in Clinical Infectious Diseases found that peripheral IV catheter infection rates in short-term use are very low (0.1% or less) when standard infection control protocols are observed.
Air embolism. If air enters the IV line and is pushed into the bloodstream, it can - in theory - cause a venous air embolism. In practice, this requires a significant volume of air (the literature suggests >50 mL in adults to cause clinically significant harm) and is almost exclusively a risk of improper line setup or failure to properly prime tubing. A qualified nurse eliminates this risk through standard line priming and monitoring. It is, however, a genuine risk with DIY IV setups - which I'll address later.
Fluid overload. Administering too much fluid too quickly can overwhelm the cardiovascular system, particularly in patients with pre-existing heart failure, kidney disease, or compromised cardiac function. This is why health screening matters. A healthy adult receiving a standard 500 mL–1 L IV drip is not at risk of fluid overload. A 70-year-old with congestive heart failure on fluid restriction absolutely is - and no responsible provider should be giving them an elective IV drip without cardiologist clearance.
Allergic or hypersensitivity reactions. Rare, but possible with any substance administered intravenously. Reactions can range from mild skin flushing to, in extremely rare cases, anaphylaxis. Proper screening (including allergy history) and having emergency medications and protocols in place mitigates this risk. I've never had an anaphylactic reaction in my practice, but I carry adrenaline and the training to use it, because "never" and "impossible" are different words.
Phlebitis. Inflammation of the vein at the cannulation site. More common with prolonged cannula use (hospital patients who have a line in for days), but occasionally seen with single IV sessions - usually presenting as redness, warmth, or a hard cord along the vein. It resolves on its own and is managed with warm compresses if needed.
The Practitioner Matters More Than the Therapy
This is the section most IV therapy websites skip, for obvious reasons.
IV therapy itself is well-established and safe. But who's administering it - and under what conditions - creates a quality spectrum so wide it's almost absurd. Let me walk you through it:
SANC-registered Professional Nurse. This is the gold standard for elective IV therapy in South Africa. A Professional Nurse (not to be confused with an Enrolled Nurse or Auxiliary Nurse - the SANC register has distinct categories) has completed a four-year nursing degree, is trained in intravenous therapy, can legally cannulate, and operates under a professional regulatory body that holds them accountable. If something goes wrong, there's a registration number, a complaints process, and professional consequences.
"Trained IV technician" or "wellness consultant." This is where it gets murky. South Africa's regulation of elective IV therapy is not as tight as it should be, and some providers use staff who have completed short courses in IV administration but are not registered nurses. They may be competent at the mechanics of cannulation - but they're not trained to recognise complications, manage adverse reactions, or assess whether a client should be receiving IV therapy in the first place. The difference between "can insert a cannula" and "can manage everything that might happen next" is the difference between a driving licence and a pilot's licence.
DIY IV kits. Yes, these exist. Yes, people buy them online. No, you should not be doing this. I'll cover this in detail below, but the short version: self-administering IV therapy without medical training is gambling with risks that a professional would eliminate in seconds.
The question to ask any provider: "Who will be administering my drip, and what is their professional registration?" If they can't answer clearly, or if the answer involves the words "trained" instead of "registered," keep looking.
Red Flags: When to Avoid IV Therapy
IV therapy is not for everyone. These are the conditions and situations where elective IV therapy should either be avoided entirely or only pursued with specialist medical clearance:
- Heart failure or cardiomyopathy. Fluid loading can worsen cardiac function. Non-negotiable - no elective IV therapy without cardiologist sign-off.
- Kidney disease (particularly stage 3+). Impaired kidneys can't handle the additional fluid and electrolyte load. IV drips that include potassium or magnesium pose a particular risk.
- Severe liver disease. Altered metabolism of vitamins and minerals can make standard drip formulations inappropriate.
- Certain medications. Anticoagulants increase bruising and bleeding risk at the cannulation site. Some cardiac medications interact with the electrolyte changes IV therapy introduces. Chemotherapy patients have complex hydration and supplement considerations. Disclose everything during your screening.
- Pregnancy without medical clearance. Some IV therapies are appropriate during pregnancy (simple hydration, for example), but the decision should involve your obstetrician. Blanket "it's fine" statements from an IV provider who hasn't consulted your pregnancy care team are a red flag.
- Active infection with fever. If your body is already fighting an acute infection, adding an elective IV load isn't necessarily helpful and could complicate things. Get the infection treated first.
These aren't just theoretical contraindications. They're the reason I conduct a health screening with every new client. If I identify any of the above, I either refer you to your doctor first or decline to treat you. That's not overcaution - it's clinical responsibility.
Red Flags: Dodgy Providers
If the previous section was about your health, this one is about your provider's standards. Here's what should make you walk away:
No health screening. If a provider is ready to stick a needle in your arm without asking about your medical history, medications, allergies, or health conditions - that's not efficiency. That's negligence. Every responsible IV therapy provider screens before they treat. Period.
No qualified staff. Ask who's inserting the cannula. Ask for their SANC registration number. If the answer is evasive, you have your answer.
Group settings with minimal supervision. Some IV lounges seat four, six, or eight clients simultaneously with one attendant managing everyone. If your nurse is monitoring multiple drips at once, who's watching yours? If you develop a reaction mid-infusion, how quickly can they respond when they're busy cannulating someone else across the room?
Suspiciously cheap prices. IV therapy involves medical-grade ingredients sourced from registered pharmacies, sterile single-use consumables, professional labour, and insurance. If someone's offering a vitamin drip for R400, ask yourself what they're cutting. (Spoiler: it's usually the ingredients, the qualifications, or the insurance.)
No emergency protocols. Ask your provider: "What happens if I have a reaction during my drip?" If the answer doesn't include adrenaline, antihistamines, and a clear escalation pathway, they're not prepared for the one time things don't go according to plan.
No professional insurance. If a provider causes harm during treatment, their professional indemnity insurance is what protects you. If they don't have it, you're unprotected - and that tells you something about how seriously they take their own accountability.
What Proper Safety Looks Like at IVgo
I'm obviously biased, but I'll tell you exactly what we do and you can measure anyone else against it:
Health screening for every new client. Before I administer anything, I review your medical history, current medications, allergies, and any contraindications. If you've got a complex health profile, I arrange blood work reviewed by a doctor before we proceed. No shortcuts.
SANC-registered Professional Nurse. That's me. Registration number verifiable on the SANC website. Four-year nursing degree, years of clinical experience, and ongoing professional development. Not a "trained technician." Not a wellness consultant. A nurse.
Sterile, single-use equipment. Every cannula, every line, every piece of equipment that touches you is sterile, single-use, and disposed of in medical waste after your treatment. Nothing is reused. Ever.
Medical-grade ingredients from registered pharmacies. The vitamins, minerals, and compounds in IVgo drips are sourced from South African registered pharmacies - not imported supplement powders or grey-market vials. You know exactly what's going into your body because it comes from a regulated supply chain.
Emergency protocols and equipment. I carry adrenaline, antihistamines, and the training to manage anaphylaxis and other acute adverse reactions. I've never needed them for an elective IV therapy client. But "prepared for the worst" isn't a marketing slogan - it's how clinical practice works.
Professional indemnity insurance. If something goes wrong (and in medicine, you plan for that possibility even when the probability is low), you're protected and I'm accountable. That's what professional insurance is for.
One client, one nurse. When I'm treating you, I'm treating you. I'm not splitting my attention between four clients in recliners. Your drip, your vitals, your experience - they have my full attention for the duration. This is one of the core reasons I chose the mobile model over the IV bar model.
IV Therapy and Medical Aid
This comes up a lot, so let me clarify: IVgo is affiliated with Discovery Health. If your medical aid plan includes a Medical Savings Account (MSA), you can claim up to 70% of IVgo treatment costs back from your MSA.
I provide you with a detailed invoice that includes the appropriate billing codes, and you submit it to Discovery. Most clients receive their reimbursement within a few days.
This doesn't apply to all medical aids or all plan types - but if you're on Discovery with an active MSA, you're likely covered for a significant portion of your treatment costs. I'm happy to help you check before you book.
The DIY IV Trend (Please Don't)
I need to address this because it keeps showing up on TikTok and Reddit: people buying IV kits online and self-administering drips at home.
I'm going to be as direct as possible: do not do this.
Here's why:
Infection risk. Without proper aseptic technique and a sterile environment, you're introducing bacteria directly into your bloodstream. That's not a localised skin infection - that's potential septicaemia. Hospital-grade sterile technique exists for a reason.
Air embolism risk. If you don't properly prime an IV line (removing all air from the tubing before it connects to your vein), you're risking a venous air embolism. A trained nurse does this automatically, every single time. Someone watching a YouTube tutorial might not.
Wrong dosing. IV vitamins and minerals have specific concentration ranges for safe intravenous administration. Too much potassium, too fast? That's a cardiac event. Too much magnesium? Respiratory depression. These aren't hypothetical - they're pharmacological realities that require clinical knowledge to navigate.
No emergency backup. If something goes wrong in a clinical setting, there's a nurse with the training and equipment to manage it. If something goes wrong in your bathroom with a kit you bought on Takealot? You're calling an ambulance and hoping they arrive in time.
The cost of a professional IV treatment - administered safely by a registered nurse - is an order of magnitude less than a hospital admission for a complication you caused by trying to save R800.
Frequently Asked Questions
Can I get an IV drip if I'm on medication?
In most cases, yes - but it depends on what you're taking. Certain medications interact with the vitamins and minerals in IV drips (blood thinners, cardiac medications, lithium, and some diuretics, among others). This is exactly why I screen every client before treatment. Bring a complete list of your medications - including supplements - and I'll assess whether any adjustments to your drip formulation are needed. If I'm uncertain about an interaction, I consult with the prescribing doctor before proceeding.
What if I'm needle-phobic?
You'd be surprised how many of my clients say this before their first drip and then book a second one the following month. I use small-gauge cannulas, I'm experienced at making the process as quick and smooth as possible, and I talk you through everything before anything happens. You can lie down, look away, and I'll let you know when it's done - which is usually within a few seconds. True clinical needle phobia (trypanophobia) is different from general nervousness, and if you've been diagnosed with it, we can discuss strategies - including topical anaesthetic cream applied before cannulation.
How do I know my nurse is qualified?
Ask for their SANC registration number and verify it on the SANC website. Every registered nurse in South Africa has a unique registration number linked to their qualification category. At IVgo, I'm a registered Professional Nurse - the highest category of nursing registration - and I'm happy to provide my registration details to any client who asks. If a provider hesitates when you ask this question, that hesitation is your answer.
Is IV therapy safe during pregnancy?
It can be, for specific treatments and specific situations - but only with medical clearance from your obstetrician or midwife. Simple hydration drips are generally considered safe and are, in fact, routinely administered in hospital during pregnancy. However, high-dose vitamin or mineral infusions, NAD+ therapy, and peptide treatments are not appropriate during pregnancy without explicit specialist approval. I won't administer elective IV therapy to pregnant clients without written clearance from their pregnancy care provider. If you want to learn more about what IV therapy involves, I've written a comprehensive guide.
What happens if something goes wrong during my drip?
If you experience any discomfort - nausea, dizziness, unusual sensations, skin reactions - I'm right there. Literally. I'm not across the room managing three other clients. I adjust the drip rate, assess your symptoms, and take the clinically appropriate action, whether that's slowing the infusion, pausing it, or stopping it entirely. I carry emergency medications (adrenaline, antihistamines) and I'm trained to manage acute reactions including anaphylaxis. In the extremely unlikely event that a situation exceeds what can be managed on-site, I initiate emergency services while providing first-response care. That's what it means to have a registered nurse administering your treatment - not just someone who can insert a needle, but someone who can manage whatever happens next.
The Bottom Line
IV therapy is safe. The evidence supports it, decades of clinical use confirm it, and millions of people receive IV infusions every year without incident.
But that safety isn't automatic. It depends on who's administering the treatment, how they're screening their clients, what they're putting in the drip, and what they're prepared to do if something goes sideways.
The biggest risk in the IV therapy space isn't the therapy - it's the gap between medical-grade service and wellness-branded shortcuts. A registered nurse with proper screening, sterile equipment, medical-grade ingredients, and emergency protocols isn't a luxury option. It's the baseline.
Ask questions. Check qualifications. Demand proper screening. And if a provider makes you feel like you're being difficult for asking - that tells you everything you need to know about their priorities.
