How to prepare for your first IV therapy session

Hydrate starting 24 hours before your appointment

Proper hydration is the single most important step you can take before IV therapy. When you arrive well-hydrated, your veins are plumper and easier to access, which means the needle insertion goes faster and causes less discomfort. Dehydration makes veins constrict and become harder to find, potentially requiring multiple attempts and extending your session.

Begin drinking water at least 24 hours before your scheduled appointment. Aim for eight to ten glasses throughout the day, or roughly half your body weight in ounces. Pay special attention to hydration the morning of your session. If you struggle to drink plain water, herbal tea, coconut water, or other non-caffeinated beverages count toward your hydration goal. Avoid excessive caffeine and alcohol in the 24 hours leading up to your appointment, as both act as diuretics and work against your hydration efforts.

On the day of your session, continue sipping water as you prepare. Many people find it helpful to drink a full glass of water 30 minutes before arriving. This gives your body time to absorb it while still leaving enough time to use the restroom if needed. If you have kidney problems or conditions that limit fluid intake, follow your doctor's guidance instead, but mention this to the IV therapy team when you arrive.

Eat a balanced meal before you go

Never arrive at IV therapy on an empty stomach. Some people worry that eating will interfere with their session, but the opposite is true. A full stomach provides energy and helps stabilize your blood sugar and blood pressure during the procedure. People who skip meals are more likely to experience lightheadedness, nausea, or dizziness during or after their infusion.

Eat a balanced meal containing protein, healthy fats, and carbohydrates two to three hours before your appointment. Good options include scrambled eggs with whole grain toast, a chicken sandwich on multigrain bread, Greek yogurt with granola and berries, or salmon with brown rice and vegetables. These meals digest at a moderate pace and provide sustained energy throughout your session.

Avoid heavy, greasy, or overly sweet foods immediately before treatment. Large fried meals can make you feel sluggish or queasy, especially if you're nervous about your first session. A light snack is better than nothing, but a full meal is ideal. Time it so you finish eating at least one to two hours before your appointment, giving your body time to begin digestion without feeling too full during the infusion.

Wear loose, comfortable clothing

Your clothing choice matters more than you might expect. Wear loose sleeves or a shirt you can easily roll up to your elbow, as the IV line typically goes in your arm. Tight sleeves restrict blood flow and make it harder for staff to access your veins cleanly. Additionally, if your sleeve is too tight, the pressure can be uncomfortable during the 30 to 60 minutes you're receiving fluids.

Dress in layers you can adjust as needed. Some people feel cold during IV therapy, particularly if the infusion includes saline solutions that are cooler than body temperature. Wearing a light jacket or sweater you can remove or adjust helps you stay comfortable. Avoid tight pants or restrictive clothing around your waist, as you'll be sitting or reclining for the duration of your session.

Wear comfortable shoes or consider going barefoot if your facility allows it. Many IV therapy lounges provide a relaxing environment, and your comfort is a priority. If you're prone to feeling cold easily, ask if you can bring a blanket from home, though most facilities provide blankets for this reason.

Gather your medical information

Before your first appointment, compile a list of all relevant medical information. You'll need to complete health history paperwork, and having this information ready speeds up the process and ensures accuracy. Bring details about:

• All current medications and supplements, including dosages
• Known allergies, especially to medications or saline
• Chronic health conditions such as diabetes, heart disease, kidney problems, or blood clotting disorders
• Previous reactions to injections or IV procedures
• Recent surgeries or medical procedures
• Pregnancy status if applicable
• Any history of fainting or vasovagal reactions

Write this information down and bring it with you, or take photos of your medication bottles so staff can reference them. If you take blood thinners or have a bleeding disorder, this is particularly important to disclose. Some medications and conditions require adjustments to IV therapy protocols or may mean certain treatments are unsuitable for you. The more complete your medical history, the safer and more effective your session will be.

Identify your veins and mention concerns to staff

Take a moment to look at your arms the day before your appointment. If you've had difficulty with IV placement in the past, or if you have small, rolling, or deep veins, mention this to staff when you arrive. They can take extra time to locate the best insertion site and may use techniques like arm positioning, warm compresses, or ultrasound guidance to make the process easier.

Some people have a condition called vasovagal syncope, where the sight of needles or blood causes fainting. If this describes you, alert the staff immediately. They can help you prepare mentally, may allow you to look away during insertion, and will ensure you're lying flat during your infusion for safety. Being honest about needle anxiety or previous difficult experiences helps staff provide better care.

If you have a preferred arm or a vein you know works well, point it out. Most people prefer their non-dominant arm to remain free, which staff will usually accommodate. If you've had lymph node removal, mastectomy, or other surgery on one arm, you typically cannot use that arm for IV placement, so communicate this clearly when you check in.

Plan to arrive 10 to 15 minutes early

Arriving early reduces stress and gives you time to complete paperwork without rushing. You'll need to sign consent forms and health questionnaires, and these take longer if you're filling them out as your appointment time approaches. Arriving early also allows you to sit comfortably, continue hydrating, and acclimate to the environment before your session begins.

Early arrival gives you the chance to ask questions before treatment starts. If you're unsure what to expect, now is the time to ask staff to walk you through the process. You can also discuss any concerns about the specific IV therapy solution you're receiving, how long it takes to infuse, and what sensations you might experience. Staff appreciate informed patients and can address your questions more thoroughly when not rushed.

Understand what happens during your session

Knowing what to expect reduces anxiety and helps you relax during treatment. Your session will follow a standard process. First, you'll check in and complete paperwork if you haven't already. A staff member will review your medical history and ask screening questions about your health and current symptoms. They'll explain the IV therapy you're receiving and answer any remaining questions.

Next, you'll be positioned comfortably, usually in a reclining chair or bed. The staff member will locate a suitable vein, clean the area with an antiseptic wipe, and insert the IV catheter. Most people describe this as a quick pinch. Once the line is in place, you won't feel pain, only the sensation of the fluid flowing through the catheter. The entire infusion typically takes 30 to 60 minutes depending on the treatment. Many people relax, read, or close their eyes during this time. After the fluid is complete, the catheter is removed and you're free to go.

It's normal to feel a slight coolness as the fluid enters your vein, especially early in the infusion. You might notice your arm feeling cold if the solution is cool, but this passes quickly. Some people experience mild flushing, a slight metallic taste, or mild tingling—all normal responses. If you feel severely uncomfortable or experience chest pain, difficulty breathing, or severe nausea, alert staff immediately.

Follow pre-appointment restrictions from your provider

If you've received specific instructions from your healthcare provider, follow them carefully. Some IV therapies, particularly those involving certain vitamins or medications, have specific requirements. For example, some treatments require fasting, while others specifically require eating beforehand. Your provider's instructions supersede general guidance, so if you were told something different from what you've read here, follow what your provider said.

If you're unsure about any restrictions or if you've been given conflicting information, contact the facility before your appointment. Phan Wellness Center can clarify what's required for your specific treatment and help you prepare correctly. Being fully prepared means your session goes smoothly and you get the maximum benefit from your treatment.
