Fatigue.
Shortness of breath with exercise.
Feeling weak or run down.
Difficulty concentrating.
Maybe you’ve been told your ferritin is low—or you’ve been taking an oral iron supplement for months and aren’t sure it’s helping.
Iron deficiency is common, but understanding your iron status isn’t always as simple as looking at one number on a lab report.
At Driip IV, we offer IV iron infusions for patients who meet specific laboratory and clinical criteria. Before receiving an iron infusion, patients must complete required laboratory testing and medical screening.
Why?
Because iron is essential—but more iron is not always better, and IV iron should only be administered when it’s medically appropriate.
Here’s what patients should know about iron deficiency, ferritin, iron testing, and when IV iron therapy may be considered.
Why Does Your Body Need Iron?
Iron is an essential mineral that your body needs to function normally.
One of its best-known jobs is helping your body produce hemoglobin, the protein inside red blood cells that carries oxygen from your lungs to tissues throughout your body.
When your body doesn’t have enough available iron, normal red blood cell production and oxygen transport can eventually be affected.
Iron deficiency can exist with or without anemia, which is one reason looking only at hemoglobin may not provide the complete picture.
What Is Ferritin?
If you’ve been researching iron deficiency, you’ve probably come across the word ferritin.
Ferritin is a protein that stores iron. Measuring serum ferritin can provide useful information about the body’s iron stores and is an important component of evaluating suspected iron deficiency.
In September 2026, the American Society of Hematology released updated evidence-based recommendations for diagnosing iron deficiency. The recommended ferritin thresholds vary depending on the patient population and clinical context.
This is an important reminder that there isn’t always one ferritin number that should be interpreted exactly the same way for every person.

Can You Have Low Ferritin Without Being Anemic?
Yes.
Iron deficiency and iron-deficiency anemia are related, but they aren’t synonymous.
A patient may have depleted iron stores before their hemoglobin drops enough to meet criteria for anemia.
That’s one reason a provider evaluating possible iron deficiency may look beyond hemoglobin alone.
Depending on the patient’s circumstances, testing may include measurements such as:
- Ferritin
- Hemoglobin
- Hematocrit
- Serum iron
- Transferrin saturation (TSAT)
- Total iron-binding capacity (TIBC)
- Mean corpuscular volume (MCV)
- Red blood cell count
The results should then be interpreted together with the patient’s symptoms, health history, medications, potential sources of blood loss, inflammatory conditions, kidney function, and other relevant factors.
Why Ferritin Can Be Tricky
Here’s something many patients don’t realize:
Ferritin can be influenced by inflammation.
Ferritin is an acute-phase reactant, meaning levels can increase in response to inflammation or infection.
As a result, a ferritin value that doesn’t appear particularly low does not always exclude iron deficiency in every clinical situation.
This is why providers may consider additional information—such as transferrin saturation and the presence of inflammatory conditions—when interpreting iron studies.
The World Health Organization specifically notes that inflammation can affect ferritin interpretation and potentially obscure iron deficiency.
This is another reason we don’t determine eligibility for IV iron based on ferritin alone.
What Can Cause Iron Deficiency?
Iron deficiency isn’t a diagnosis that should simply lead to “take more iron.”
It’s important to ask why the iron is low.
Potential contributors can include:
- Heavy menstrual bleeding
- Blood loss
- Pregnancy and increased iron requirements
- Inadequate dietary iron intake
- Gastrointestinal conditions affecting absorption
- Previous gastrointestinal surgery
- Chronic inflammatory conditions
- Certain medications
- Frequent blood donation
- Other medical conditions or sources of blood loss
Depending on a patient’s age, sex, symptoms, medical history, and laboratory findings, additional evaluation may be necessary to determine the underlying cause.
Treating the deficiency is important.
Understanding why it developed can be just as important.
What Does Low Iron Feel Like?
Symptoms vary considerably between patients and depend partly on the severity and duration of the deficiency.
Possible symptoms can include:
- Fatigue
- Weakness
- Reduced exercise tolerance
- Shortness of breath
- Dizziness or lightheadedness
- Headaches
- Difficulty concentrating
- Feeling unusually cold
- Restless legs
- Rapid heartbeat or palpitations
- Pale skin
- Hair or nail changes
However, these symptoms are not specific to iron deficiency.
Fatigue, for example, can have dozens of potential causes.
That’s why laboratory testing matters.
We don’t want to assume someone needs iron simply because they’re tired.
Oral Iron vs. IV Iron
For many patients with iron deficiency, oral iron is an appropriate first-line option.
Oral supplementation is convenient, relatively inexpensive, and can be effective when the gastrointestinal tract absorbs it adequately and the patient tolerates treatment.
However, oral iron isn’t the right solution for everyone.
Some patients experience gastrointestinal side effects such as constipation, nausea, or abdominal discomfort. Others may have conditions that interfere with iron absorption, ongoing blood loss, significant deficiency, or circumstances where oral replacement has not been sufficient.
In those situations, a healthcare provider may consider intravenous iron therapy.
What Is an Iron Infusion?
An iron infusion delivers an iron-containing medication intravenously.
Because the medication is administered directly into the bloodstream, it does not depend upon gastrointestinal absorption in the same way oral iron does.
There are multiple formulations of IV iron, and their dosing schedules and administration requirements differ.
At Driip IV, iron therapy is administered according to our established clinical protocol and medical standing order.
IV iron is not the same thing as one of our regular Lifestyle Driips.
It’s a medical treatment that requires appropriate laboratory evaluation, screening, dosing, monitoring, and medical oversight.
Why Driip IV Requires Specific Labs Before Iron Infusions
This is one of the most important things we want patients to understand.
You cannot simply schedule an iron infusion because you’re tired or because someone once told you your iron was low.
Before administering IV iron, Driip IV requires specific, current laboratory information to determine whether the patient meets our established treatment criteria.
Depending on the patient’s individual circumstances and our clinical protocol, laboratory review may include:
Ferritin — helps assess stored iron.
Hemoglobin + Hematocrit — provide information about red blood cells and anemia.
Transferrin Saturation (TSAT) — provides information about how much circulating transferrin is carrying iron.
Serum Iron + TIBC — provide additional information about circulating iron and iron-binding capacity.
MCV + RBC Count — provide additional information about red blood cell characteristics.
Kidney Function (including eGFR when required) — may be relevant to treatment eligibility, medical evaluation, and the overall clinical picture.
Additional testing may be required depending on the patient’s medical history, age, symptoms, or laboratory findings.
Why So Much Testing?
Because our goal isn’t simply to give iron.
Our goal is to give iron to the right patient, at the appropriate dose, under appropriate medical supervision.
Laboratory testing helps us determine whether iron deficiency is actually present, assess its severity and context, identify findings that may require additional evaluation, and reduce the risk of administering iron when it isn’t appropriate.
Iron overload can also be harmful.
That is why iron therapy should be based on documented clinical need—not simply symptoms or patient preference.
At Driip IV, patient safety comes before getting someone into the chair.
What Happens After We Receive Your Labs?
Once the required laboratory results are available, they are reviewed according to Driip IV’s established clinical criteria.
If the results meet our standing-order requirements and there are no other contraindications or concerns, the patient may be cleared to schedule an iron infusion.
If something falls outside of the established criteria, that doesn’t necessarily mean the patient can never receive treatment.
It may mean the case requires additional review by our Medical Director or another appropriate healthcare provider before proceeding.
In some cases, we may recommend that a patient follow up with their primary care provider, hematologist, gastroenterologist, OB/GYN, or another specialist for additional evaluation.
We would rather investigate a questionable result than administer iron when the clinical picture isn’t clear.
Medical Oversight Matters
Iron infusions aren’t something we approach casually.
Driip IV operates with physician oversight, and patients must meet our established criteria before receiving treatment.
That oversight is particularly important because IV iron carries potential risks.
Infusion reactions can occur, and although serious hypersensitivity reactions are uncommon, they are possible with IV iron products.
For that reason, patients are monitored during administration and according to the specific iron formulation and clinic protocol.
What Happens During an Iron Infusion?
Before treatment begins, clinical staff confirm the patient’s treatment authorization and perform the appropriate pre-infusion assessment.
Peripheral IV access is established and checked for patency before iron administration.
The prescribed iron formulation is then administered according to the ordering provider’s protocol.
Patients are monitored during treatment for symptoms such as:
- Itching or rash
- Dizziness or lightheadedness
- Changes in blood pressure
- Shortness of breath
- Chest discomfort
- Swelling
- Significant nausea
- Pain or abnormal sensation at the IV site
- Other unexpected symptoms
Patients should immediately tell clinical staff if something doesn’t feel right.
Depending on the iron formulation and protocol, post-infusion observation may also be required.
What Happens After an Iron Infusion?
Receiving an iron infusion doesn’t mean laboratory monitoring is finished.
Your healthcare provider may recommend repeat testing after treatment to evaluate your response and determine whether additional treatment is appropriate.
The goal isn’t necessarily to make ferritin as high as possible.
The goal is to correct an identified deficiency appropriately while avoiding unnecessary or excessive iron administration.
Your treatment plan may therefore depend on:
- Your starting laboratory values
- The cause of your iron deficiency
- The iron formulation used
- Your prescribed dose
- Your response to treatment
- Ongoing blood loss
- Underlying medical conditions
- Follow-up laboratory results
Who Might Be Considered for IV Iron?
IV iron may be considered in certain patients with documented iron deficiency when clinically appropriate.
Examples can include patients who:
- Cannot tolerate oral iron
- Do not adequately respond to oral supplementation
- Have difficulty absorbing oral iron
- Have significant documented iron deficiency
- Have ongoing iron losses
- Have certain gastrointestinal or chronic medical conditions
- Have another clinical reason a provider determines IV replacement is appropriate
Meeting one of these descriptions does not automatically mean someone qualifies for an iron infusion.
Individual laboratory results and medical history still need to be reviewed.
Don’t Guess About Your Iron
If you’ve been exhausted for months and suspect iron deficiency, the first step isn’t necessarily buying another supplement—or scheduling an infusion.
Start with the right testing.
Iron deficiency can be overlooked, but unnecessary iron treatment isn’t the answer either.
The best approach is to determine:
Are you actually iron deficient?
How significant is the deficiency?
Why are you deficient?
Is oral or IV replacement appropriate?
Is there an underlying cause that needs further evaluation?
Those are the questions that guide safe treatment.

FAQs:
What are the origins of IV therapy:
Research is clear that when you address underlying nutrition deficiencies, your body heals. Dr. Myers, creator of IV nutrient therapy and the Myers Cocktail, theorizes that all chronic disease starts with nutritional deficiency. Here is research from Pubmed regarding IV nutrient therapy and improvement of chronic symptoms: https://pubmed.ncbi.nlm.nih.gov/12410623/.
What is the cost of IV therapy:
Pricing for an IV Driip ranges from $130 – $395 depending on your needs and goals. See our full line of products and prices here.
What frequency do you reccomend:
Frequency is dependent upon your current level of health, how long you have been experiencing symptoms, and your health goals – everyone is different.
It is typically best to repeat a given IV therapy once a week for six weeks. Then, re-assess if your body is ready to move to maintenance care (one time a month), or if a more frequent schedule would be beneficial.
