Your First IV Drip: What to Expect Before, During and After

IV drip therapy has become one of the most widely available wellness treatments in Ireland, offered by dedicated infusion clinics in Dublin, Cork, Galway and Belfast as well as by general practices and aesthetic clinics adding it to an existing list. Booking one is now about as easy as booking a facial, which is exactly why the first appointment can feel disorienting. What arrives is closer to a short outpatient procedure than a pampering session.

That gap between the marketing and the reality is worth closing before you go rather than while you are sitting in the chair. An IV drip means a cannula in a vein, a prescription medicine entering your bloodstream, and a period of monitored sitting while it runs. None of that is frightening, and for most healthy adults the whole thing is uneventful, but it does mean the appointment has a clinical shape: screening questions, consent, a blood pressure check, and a nurse or doctor who stays within reach of you for the duration.

This guide walks through it in order, from the screening conversation to the bruise you might find the next morning, with realistic Irish costs and an honest account of what one session can and cannot do.

Any clinic worth attending takes a history before it takes payment. Expect questions about your medical conditions, particularly anything involving your heart, kidneys or liver, your current medications and supplements, any previous reaction to an injection or infusion, whether you are pregnant or breastfeeding, and whether you have ever fainted during a blood test. Some clinics send this as a form beforehand, others work through it in the room.

The screening exists for specific clinical reasons rather than as paperwork. Heart failure and reduced kidney function change how your body handles an extra half litre of fluid. A known glucose-6-phosphate dehydrogenase deficiency matters a great deal if high-dose vitamin C is being considered: a 2026 systematic review of high-dose intravenous vitamin C identified haemolysis in people with that deficiency, alongside oxalate nephropathy, as the main serious risks, and recommended pre-screening specifically to avoid them. The calcium in some blended formulations can interact with cardiac medicines such as digoxin.

In Ireland the person carrying out that assessment should be a registered doctor, or a registered nurse working within their scope of practice, and the infusion should be prescribed rather than picked off a board. The Nursing and Midwifery Board of Ireland holds registered nurses to published standards and a professional code, and the Medical Council does the same for doctors. If nobody asks you anything medical before the cannula goes in, that is the moment to reconsider the appointment rather than the moment to roll up your sleeve.

After screening and consent you will be seated in a reclining chair, usually in a shared treatment room or a curtained bay, and asked which arm you prefer. A tourniquet goes on the upper arm, the skin over the chosen vein is cleaned with an antiseptic wipe, and a small cannula is inserted, most often into the back of the hand or the inside of the elbow. The cannula is a short flexible tube over a needle, and the needle is withdrawn once the tube is sited, so nothing rigid stays in your arm.

The line is then connected to the infusion bag hanging on the stand beside you and the flow rate is set. Some clinics use an electronic pump, others rely on gravity and a roller clamp, and both are normal. You will be asked how you feel in the first minute or two, because that is when an immediate reaction would declare itself, and your blood pressure may be rechecked once the drip is running steadily.

From there it is mostly waiting. You can read, answer email, or sleep. Your arm needs to stay reasonably still but you are not immobilised, and staff will walk you to the toilet with the stand if the volume in the bag and the state of your bladder make that necessary. At the end the clamp is closed, the cannula is slipped out, and firm pressure with gauze goes onto the site for a minute or two before a small dressing.

The insertion is the part people worry about and it is over quickly. It feels like a blood test with a little more sensation: a sharp scratch lasting a second or two, sometimes with a brief ache as the tube is advanced. If the first attempt does not work, and occasionally it does not, the clinician will try a second site. Saying in advance that you are a difficult stick, or that you tend to faint, genuinely helps, because they can recline the chair further and choose a smaller cannula.

Once the infusion is running most people feel very little. The two sensations reported most often are a coolness travelling up the arm, because the fluid is at room temperature rather than body temperature, and a mineral or faintly metallic taste at the back of the mouth. Magnesium, present in many blended formulations including the Myers cocktail, characteristically produces a spreading warmth or flushing and can leave you a little light headed if it goes in quickly. Slowing the drip rate settles both, and asking for it to be slowed is a routine request rather than a complaint.

Some sensations are not routine and should be reported the moment you notice them: chest tightness, difficulty breathing, itching or a rash, sudden nausea, or pain and swelling around the cannula. That last one usually means fluid is tracking into the tissue rather than the vein. It is uncomfortable and the line needs resiting, but caught early it is not dangerous, which is the whole reason someone stays nearby while the bag empties.

Budget more time than the infusion itself needs. A straightforward vitamin or hydration drip runs for roughly 30 to 60 minutes, and the appointment around it, including screening, cannulation and a few settling minutes afterwards, usually takes 60 to 90 minutes in total. NAD+ is the outlier. Those infusions are deliberately slow, from about 90 minutes to several hours depending on the dose, because pushing NAD+ in quickly causes chest tightness, flushing and cramping.

On price, most single IV sessions in Ireland fall between EUR 100 and EUR 295, with simple vitamin C or hydration drips at the lower end and complex blended or high-dose formulations at the upper end. A Myers cocktail typically sits between EUR 150 and EUR 250. NAD+ is priced separately and considerably higher, commonly EUR 250 to EUR 800 per session depending on dose and infusion time. Some clinics charge a first-visit rate that includes the consultation, and most sell multi-session courses at a discount, which is worth declining until you have done one session and know how you respond.

Ask what the quoted price covers before you book: the consultation, the formulation itself, any blood tests the clinic wants beforehand, and whether a follow-up visit is expected. Prices last checked September 2026 and vary considerably between clinics, so confirm current rates directly with the provider.

You can drive and return to work straight after a routine drip unless you felt light headed during it, in which case sit for longer, have something to eat, and let the clinic recheck your blood pressure before you leave. Most will ask you to keep the dressing on for a few hours and to avoid heavy lifting with that arm for the rest of the day.

Two harmless after-effects surprise first timers. Bright yellow urine for several hours is riboflavin, one of the B vitamins, being cleared by the kidneys, and it means nothing beyond that. A bruise at the cannula site can appear the following morning even when the insertion went perfectly, particularly if you take aspirin, an anticoagulant or fish oil, and it fades over a week like any other bruise.

As for how you feel, expect something modest. People commonly describe feeling hydrated, a little brighter, and sometimes sleepy for an hour or two. If you arrived genuinely dehydrated, that improvement is real and easily explained. If you did not, the sensation is harder to attribute to the contents of the bag, and the evidence discussed below is a reason to hold it loosely. A sudden dramatic transformation is not the usual experience of a first drip, and a clinic that promises one is overselling what it is about to give you.

Some people should not have an elective wellness drip at all, and others need a doctor to weigh it up properly rather than tick a consent box. If you have heart failure, significant kidney disease or a fluid restriction, the volume alone can be a problem and the decision belongs with the team managing that condition. If you are pregnant or breastfeeding, the sensible default is to skip elective infusions unless your maternity team has specifically advised otherwise. If you have glucose-6-phosphate dehydrogenase deficiency, high-dose vitamin C should be off the table for the reason described earlier.

High-dose vitamin C carries a second caution involving the kidneys. A 2025 case report in the Journal of Nephrology described oxalate nephropathy, a form of kidney injury caused by calcium oxalate crystals, in a patient receiving high-dose intravenous vitamin C, and the 2026 systematic review of high-dose intravenous vitamin C lists the same problem among its main serious risks with very large or repeated doses. A single case report is weak evidence when it stands alone, but it points in the same direction as the review, and together they are a good reason why anyone with existing kidney impairment or a history of kidney stones should not be having high-dose vitamin C infusions casually.

There are a few other things always worth flagging to the clinic: any cancer treatment in progress, because interactions with chemotherapy need input from your oncology team rather than from an infusion clinic; any anticoagulant; and any history of reacting to an infused substance. None of these are automatic refusals. They are simply the reasons the prescribing decision needs a clinician who has your full history in front of them.

This is where expectations matter most, and where the honest answer is less exciting than the marketing. A 2023 review in the Drug and Therapeutics Bulletin looked specifically at intravenous vitamin injections promoted to reduce stress, increase energy or boost immunity, and concluded that there is a lack of high-quality evidence that high-dose vitamin infusions are necessary or offer any health benefit in the absence of a specific vitamin deficiency or medical condition. It also noted that harms are possible from non-physiological quantities of some vitamins and minerals, and that licensed injectable vitamins which are prescription-only medicines should be supplied and administered only by appropriately qualified healthcare professionals.

Intravenous vitamins do have well established places in medicine. They are used in malabsorption syndromes with severe depletion, in Wernicke's encephalopathy, and in critical illness. What those uses have in common is a diagnosis first and an infusion second, which is the reverse of how wellness drips are usually sold.

That is not an argument that nothing happens when you have one. Fluid corrects dehydration, and correcting a measured deficiency relieves the symptoms of that deficiency. It is an argument for a particular mindset going in. If you have a documented deficiency, the infusion is treating something measurable and repeat bloods will show whether it worked. If you do not, you are buying hydration, a quiet hour and a plausible mechanism rather than a demonstrated outcome, at EUR 100 or more a time. The regulatory position in Ireland points the same way: prescription-only medicines may not be advertised to the public under the Medicinal Products (Control of Advertising) Regulations 2007, so a clinic marketing infusions the way a cafe markets smoothies is already stretching a line that exists for a reason.

A short list of questions separates a well-run clinic from a retail operation. Who is prescribing this infusion, and are they a registered doctor or a registered nurse prescriber? Who is inserting the cannula, and who stays on site while it runs? What exactly is in the bag, and in what quantities? What happens if I react, and what emergency equipment and training are here? And what in my history or blood results makes this the right formulation for me rather than a different one?

Well-run clinics answer all five without hesitation, and some will decline to treat you if the answers do not line up. A refusal like that is a quality signal rather than poor service. It is equally reasonable to ask whether the clinic will take baseline bloods before recommending a course, because that is precisely the difference between treating a measured deficiency and guessing at one.

Gerovia lists twenty five providers offering IV drip therapy across Ireland and Northern Ireland, ranging from single practitioner clinics to multi site groups, and the meaningful variation between them is in clinical governance rather than in the contents of the bag. Choose on the basis of who takes responsibility for you, not on the length of the menu.
