What is IV Therapy? This complete beginner’s guide to IV Therapy covers everything you need to know.

The circulatory system of the body is made up of the heart, blood vessels, and blood. Blood flows from the heart to all body tissues to supply oxygen and nutrients. Unwanted by-products are also removed from the tissues by the blood for excretion from the body.

The blood vessels which help move blood around the body are the arteries and veins. Blood flow in the artery is at high pressure because the heart pumps blood into the heart. On the other hand, the veins return the blood back to the heart at a far lower pressure. This makes the vein an excellent route for delivering therapeutic agents directly to the tissues.

IV therapy is a method of administering treatment that involves the direct delivery of medicinal substances directly into the bloodstream via a needle or cannula. The use of IV therapy in treating individuals has existed for decades.

In the 1832 cholera epidemic in London, it was recorded that “injecting a weak saline solution into the veins of the patient [had] the most wonderful and satisfactory effect…” Vitamin-laden fluids and mineral-rich fluids can be given via IV therapy.

IV therapy delivers fluids through a tiny needle straight to the bloodstream. These fluids have vitamins, minerals, or medications that hydrate or relieve unpleasant symptoms.

Since IV therapy bypasses the digestive system, cells can absorb nutrients much faster than they would otherwise. Because of this, many people experience symptom relief in mere minutes.

How does IV Therapy work?

IV therapy works by delivering vitamins and minerals into the bloodstream through a drip. Usually, this takes place in a medical office under medical supervision. But you can also receive IV therapy in the comfort of your home via a mobile provider. The process usually takes about 30 minutes to an hour.


A medical professional takes your medical history and performs a short medical exam. An IV is administered only after a thorough assessment has been conducted to determine the most appropriate treatment. Some relevant details that will be obtained include your age, the work you do, current symptoms you are experiencing, your medical history, medications you routinely take, previous surgeries you have undergone, known allergies, relevant family history, and your diet. The assessment also involves a brief examination to check your heart rate, breathing rate, oxygen levels, temperature, and blood pressure. All this information will guide the choice of fluids and add-ins that will suit your body’s needs.


The professional inserts a tiny needle into one of your veins and secures it. A tube connects the needle to the IV drip. The drip consists of saline, vitamins, and minerals customized to each patient’s symptoms.


While receiving IV therapy, your vital signs are regularly monitored to make sure the IV drip flows at the correct rate until the treatment is complete.


Once the treatment has been administered, it is removed carefully, and pressure is applied to the site to prevent bruising or bleeding.

What Happens to Your Body When You Get an IV Drip?

After receiving an IV drip with vitamins, your body will feel the effects within minutes. This includes hydration, wound healing, damaged cell repair, electrolyte replacement, and improved joints, muscles, and bodily functions. Additionally, various medications can be added to IV drips to relieve pain, nausea, and other unpleasant symptoms.

What conditions benefit from IV therapy?

What kind of nutrients can you get from IV therapy?

IV therapy is a potent method of delivering vital nutrients to the body without interference from the digestive system.

The nutrients delivered can be adjusted based on an individual’s needs and requirements.

How long does IV therapy take and how long do the effects last?

IV fluid therapy takes 15-90 minutes to complete. Some patients still feel the effects for four days to two weeks after the infusion.

An IV drip infusion usually lasts a few hours after absorption. You may experience frequent urination after receiving the IV fluids. This is due to the kidneys filtering your blood and excreting toxins and unwanted substances into the urine.

It usually takes a couple of hours for IV fluids to leave your body. Any IV therapy will leave vitamins, minerals, and other nutrients in your body for days, weeks, or months, depending on your needs.

What are the benefits of IV therapy?

  1. It has a fast onset of action: The oral route is the commonest route for taking fluids, vitamins, and other medications. However, it has a drawback which is the long duration it takes before the effect is seen. This is because it has to be processed first by the intestine before it can be absorbed into the blood for use by the tissues. This is not the case with IV therapy. By passing fluids via the vein, it is made available to the tissue in a very short time.
  2. It has a high bioavailability: Bioavailability is the “extent a substance or drug becomes completely available to its intended biological destination”. IV therapy bypasses the digestive tract. Substances given orally which go through the digestive tract are worked upon by the stomach acid and the digestive juices of the intestine. In many cases, a significant proportion of the administered therapy may be rendered inactive by this process, such that only a small percentage of it gets to the target tissues and organs where its beneficial effect is to be felt. Apart from the effect of the digestive tract, all substances absorbed from the intestine will first pass through the liver. Unfortunately, a substantial proportion is again processed by the liver, further reducing the bioavailability. IV therapy easily overcomes this by making the fluid and its component immediately available to its intended destination. The bioavailability of IV therapy is 100%.
  3. It rehydrates your body: 60% of your body weight is made up of water. Dehydration occurs when fluid intake is insufficient or when excess fluid is lost from the body such as in diarrhea or vomiting. IV therapy can be used to infuse fluid directly into the blood thereby rehydrating the body and replenishing the blood volume.
  4. It can correct electrolyte abnormalities: Electrolyte abnormalities such as low levels of sodium, potassium, or chloride in the body can be corrected by IV therapy. Various types of fluids containing the needed salts can be administered based on the requirement of each individual.
  5. It can be used to administer vitamins: Vitamins are essential for your physical and emotional well-being. A deficiency of vitamins can cause a number of symptoms such as poor eyesight, weak bones, fatigue, bleeding gums, pins and needles, and lack of energy. IV therapy can be used to supply the needed vitamins to refill and replenish your body store.
  6. It causes physical and emotional wellness: Since many Americans don’t receive all the nutrients they need from food, they don’t feel as healthy as they should. This can lead to chronic fatigue, poor sleep, low energy, and other problems.
    People who received IV therapy report improved mood, better sleep, and higher energy levels.

When should you not get IV therapy?

There are certain circumstances where it is unsafe to receive IV fluid therapy. You should not get IV therapy if you have any condition in which the body is producing excess fluids or is unable to remove fluids easily from the body. These include:

  1. Heart failure
  2. Kidney disease
  3. Liver cirrhosis

What are the side effects of IV therapy?

Taking IV therapy can cause side effects in some people, so it’s very important to receive treatment from a trained professional who can monitor your body’s response.

IV fluid therapy has been associated with the following side effects:

To avoid these side effects, you must inform your healthcare professional of any medications or supplements you take and any previous reactions you have had. Most of these adverse events will only occur when universal precautions on safety are not adhered to or when untrained personnel administers the therapy. A reputable provider will have fewer risks, so ensure you speak to the right team.

What are the Pros and Cons of IV fluid therapy?


  1. Available Customization: You can customize your IV package to suit specific needs. For example, if your diet is low in vitamin B12, as is the case with most vegetarian diets,  you can request a B12 add-in.
  2. Optimal hydration: Up to 60% of the human body is water, yet many Americans suffer from chronic dehydration. Getting enough water isn’t always easy, and if you’re sweating it away frequently, it’s even harder to stay hydrated. Traditional oral supplementation may not suffice in some cases. The saline present in all IV therapy packages can allow you to experience how optimal hydration feels.
  3. Immediate Benefits: One of the best features of IV therapy is that its effects set in very quickly. Many people begin to feel more energized and alert within minutes of treatment. IV therapy has nearly immediate benefits compared to medication or drinking water. So if you need to feel better fast, you’ll find no better option than IV therapy.
  4. Convenience: IV therapy is fast and convenient. The process requires little effort aside from answering a few questions and holding out your arm. You can even receive this therapy from the comfort of your home. If you’re feeling terrible due to a hangover or an illness, you can easily get relief from your symptoms.


It should be noted that IV therapy should not be used long-term or as a substitute for a healthy diet. Despite vitamin IV treatments’ drawbacks, most can be minimized with close supervision by a qualified healthcare professional. Talk with your RN, paramedic, or medical professional about your symptoms and treatment goals.

Drip Bar vs. In-Home IV Therapy: Where to Get an IV?

IV drip bars are a lot like spas. They usually offer wellness services along with IV therapy. Drip bars often deliver a “healing atmosphere” and may even have a social element. In this case, drip bars are best for people who want to improve their mood and increase energy (not treat an illness). In-home IV therapy is ideal for people who don’t want to spread their illness or go out in public. It’s a convenient choice that brings IV therapy to your door and administers it in your home.

How do you feel after IV therapy?
After IV therapy, you should feel like you have more energy. And if you had pain or nausea, those symptoms should have disappeared or at least improved. As a result of the magnesium in many IV drips and the increased fluids, you may feel sleepy. Your body will need some time to adjust to the increased fluids since magnesium relaxes the muscles.

Does IV therapy hurt?
The initial sting of the needle going in will feel like a pinch, but once it is placed, it should not hurt. Healthcare professionals well versed in IV therapy are skilled at finding the right vein for infusing the therapy. As a result, you may experience a dull burning sensation if your IV includes glutathione or certain medications. IV professionals know to infuse these add-ins slowly, reducing discomfort.
