How to Prepare for an IV Therapy

Preparing for an IV therapy appointment comes down to four things: giving your nurse a complete health and medication history, arriving fed and hydrated, making your veins easy to reach, and planning around the specific drip you booked. Most of these steps take only a few minutes, and each one affects how smoothly the IV goes in, how comfortable the session feels, and whether a formula is a safe fit for you.

This guide covers the steps to do before you arrive at the clinic.

Your Health History Is the Most Important Part of IV Prep

An accurate health history is the information a nurse uses to decide whether a drip, a dose, or an infusion speed is right for you. Write these down before your appointment so nothing gets missed during intake:

• Prescription medications with doses: especially blood thinners, diuretics, blood pressure medication, and insulin or other diabetes drugs

• Supplements and over the counter products: including any high dose vitamins you already take daily

• GLP-1 medications: semaglutide, tirzepatide, or similar

• Kidney or heart conditions: including a history of kidney stones or anything that limits how much fluid your body handles well

• G6PD deficiency: known, suspected, or in your family

• Pregnancy or breastfeeding: including a possible pregnancy

• Past reactions: to IV vitamins, injections, latex, or medical tape

Most of these do not rule out treatment. They change it. Someone on a blood thinner may need longer pressure on the site afterward to limit bruising. Someone with reduced kidney function may need a smaller fluid volume or a different formula.

If you use a GLP-1 medication, bring your medication list to every IV visit. The FDA prescribing information for semaglutide notes that nausea, vomiting, and diarrhea can lead to dehydration, so your fluid status matters more on treatment days.

Some Drips Need Their Own Preparation

Drip specific preparation means the extra steps certain formulas require because of their dose, ingredients, or infusion length. Three cases come up most often.

High-Dose Vitamin C

• A review of adverse events by Padayatty and colleagues (PLoS One, 2010) found high dose IV vitamin C to be generally well tolerated, with G6PD deficiency and kidney impairment as the known exceptions

• Ask whether a G6PD screening result is needed before your first high-dose vitamin C IV, and bring any prior result you have

• Higher doses take 45 to 90 minutes, so book a slot with room on both ends

NAD+

• NAD+ is infused slowly, which is why sessions run longer than a standard drip

• In a pilot study published in Frontiers in Aging Neuroscience (Grant et al., 2019), researchers gave NAD+ at a fixed, slow rate over six hours

• An NAD+ IV session at our clinic typically runs 2 to 4 hours, so use the restroom before you start and bring something to do

• Tell the nurse about any discomfort during the infusion, since the drip rate can be slowed

Coming In While Feeling Run Down

• Mild early symptoms like a scratchy throat or fatigue are a common reason people book immunity IV drips

• A fever of 100.4°F or higher, vomiting, chest pain, or trouble breathing are reasons to call the clinic before coming in

• Those symptoms may need urgent care or a physician visit rather than a wellness drip

Decide What You Want the Session to Address

A clear goal shortens intake and helps the nurse match a formula to what you actually need. Think about which of these sounds most like you:

• Low energy that keeps coming back: an afternoon slump or post-workday fatigue points toward energy IV drips

• Dull or uneven skin tone: guests focused on complexion often ask about skin brightening IV therapy

• Recovery from a hard workout, travel, or a stomach bug: hydration and electrolyte formulas are the usual starting point

• Weight management: guests who use GLP-1 medication can pair IV visits with a medical weight loss program

• Not sure: that is fine, and the nurse can recommend a starting point during intake

If you have recent lab work showing iron, B12, or vitamin D levels, bring it. A documented number gives the nurse more to work with than a description of how you feel.

How to Make Your Veins Easier to Access

Vein access is how easily a nurse can find and place an IV in a suitable vein, and you can influence it before you arrive. Small steps make a measurable difference:

• Hydrate in the hours beforehand: well filled veins are easier to see and feel. Our guide on what to eat and drink before IV therapy gives the amounts and the timing.

• Keep your hands and forearms warm: in a randomized trial published in the BMJ (Lenhardt et al., 2002), warming the hand and lower arm before IV placement reduced both the time and the number of attempts needed

• Plan for cold weather: on a winter morning in the Merrimack Valley, wear gloves on the drive in and keep the car heat on until you park

• Dress for access: short sleeves, or loose sleeves that push above the elbow without squeezing

• Skip heavy lotion on your arms that day: antiseptic wipes and tape hold better on clean skin

• Share your history: if past IV starts were difficult, say so at booking and tell the nurse which arm or vein has worked before

Preparing If Needles Make You Anxious

Needle anxiety is a common fear response to injections and IV placement, and a little planning makes it much easier to manage. You are far from alone: a systematic review and meta-analysis in the Journal of Advanced Nursing (McLenon and Rogers, 2019) estimated needle fear in roughly 20 to 30 percent of young adults.

• Tell the nurse at check-in so they can recline your chair and talk you through each step

• Do not skip food beforehand, since an empty stomach adds to the chance of feeling lightheaded

• Bring headphones or a show to focus on during placement

• If you have ever fainted during a blood draw, mention it so you can lie back before the needle goes in

• Look away and breathe slowly during the few seconds of insertion

What to Bring and How Much Time to Block

A prepared appointment bag holds your health information, something to pass the time, and a layer for warmth. Pack these the night before:

• Photo ID and a payment method

• Your written medication and supplement list

• Recent lab results or a G6PD result, if you have them

• Phone charger, laptop, book, or headphones

• A light sweater, since room temperature fluids can make you feel cool

• A water bottle for after the session

Then block your calendar based on the drip:

Avoid booking right before a meeting or pickup you cannot be late for. First visits include a longer intake than follow-ups.

A Simple Prep Timeline for the Day Before and Day Of

A prep timeline is a short schedule that spreads these steps out so nothing lands at the last minute.

Aftercare is simple and covered in our first session guide. Our licensed nurses review every guest's history before treatment, so the more complete your preparation, the more precisely your drip can be tailored to you.

Always disclose your full health history, medications, and any known conditions to the nursing team before treatment, and seek emergency care for chest pain, trouble breathing, or high fever.
