Being told that you need intravenous immunoglobulin, or IVIG, therapy can bring both relief and uncertainty.
You may finally have a treatment plan, but you may also have questions:
- How long will the infusion take?
- What will the treatment feel like?
- Should I eat beforehand?
- What should I bring?
- Will I be able to drive afterward?
- What side effects should I watch for?
- Will a nurse stay with me?
- Can future treatments be given at home?
Knowing what to expect can make your first infusion feel more manageable.
IVIG is a physician-prescribed treatment made from immunoglobulin G antibodies derived from donated human plasma. It is used for a variety of immune, neurologic, hematologic, and inflammatory conditions.
The exact experience differs by patient because IVIG products, doses, infusion rates, underlying conditions, and medical histories vary.
Your physician, pharmacist, and infusion team will provide instructions specific to your treatment.
At Mercy Infusion, our goal is to help patients understand both the clinical and practical steps before therapy begins, from insurance authorization and medication coordination through the first infusion and ongoing treatment.
Before Your First IVIG Infusion
Before treatment day arrives, several things usually need to happen.
Your physician will prescribe:
- The IVIG product
- Dose
- Treatment frequency
- Infusion rate or protocol
- Premedications when appropriate
- Laboratory monitoring when required
- Treatment setting
Mercy Infusion then helps coordinate the administrative and pharmacy side of treatment, which may include insurance benefits verification, prior authorization, medication access, and scheduling.

Make Sure Your Care Team Knows Your Medical History
Before your first IVIG infusion, provide your healthcare team with an accurate medical history.
Be sure to discuss:
- Current medications
- Medication allergies
- Previous reactions to blood products or immunoglobulin
- Kidney problems
- Heart conditions
- History of blood clots
- Diabetes
- Migraine history
- Pregnancy or plans for pregnancy
- Recent illness or infection
- Any significant change in your health
IVIG products carry product-specific warnings and precautions. Some IVIG products have warnings concerning thrombosis, kidney problems, hypersensitivity reactions, hemolysis, and other serious complications.
The appropriate precautions depend on the individual product and patient.
Your healthcare team needs accurate information to determine how your infusion should be administered and monitored.
Ask Whether You Need Laboratory Testing
Some patients require laboratory testing before beginning treatment or during ongoing IVIG therapy.
Testing depends on the diagnosis, prescribed medication, medical history, and physician’s treatment plan.
Your physician may monitor factors such as:
- Kidney function
- Blood counts
- Immunoglobulin levels
- Other condition-specific laboratory values
Do not assume you need a particular test simply because another IVIG patient receives it.
Follow the monitoring plan established by your physician.
Follow Your Care Team’s Hydration Instructions
Patients often hear that they should “drink lots of water” before IVIG.
Adequate hydration can be important for some patients, and certain IVIG prescribing information advises avoiding volume depletion before treatment. However, hydration recommendations should be individualized, particularly for patients with heart, kidney, or fluid-balance concerns.
Follow the instructions provided by your physician, pharmacist, or infusion nurse.
Do not dramatically increase fluid intake on your own if you have been told to limit fluids or have a medical condition that affects hydration.
Should You Eat Before IVIG?
Unless your healthcare team gives you different instructions, many patients can eat normally before an IVIG infusion.
A light meal before treatment may be more comfortable than arriving hungry for an infusion that could last several hours.
If your physician has given you fasting instructions for another medical reason, follow those instructions instead.
Consider having easy-to-eat snacks available if your treatment setting permits them.
Take Medications as Directed
Continue your usual medications unless your physician tells you otherwise.
Some patients may be prescribed medications before IVIG to reduce the likelihood or severity of certain infusion-related symptoms.
These are sometimes called premedications.
Depending on the patient and physician’s orders, premedication might include specific prescription or over-the-counter medications.
Do not take extra medication simply because you have heard that another IVIG patient does so.
Premedication should follow your individual treatment plan.
Dress Comfortably
IVIG infusions can take several hours.
Wear clothing that allows you to sit comfortably and provides easy access to your arms if a peripheral IV will be used.
Good options may include:
- Loose-fitting shirt
- Short sleeves
- Sleeves that easily roll up
- Comfortable pants
- Layers you can add or remove
Some patients feel colder than usual while sitting still for an extended period, so a sweater or light blanket can be useful.
What Should You Bring to Your First IVIG Infusion?
Depending on where you receive treatment, consider bringing:
- Current medication list
- Insurance information if requested
- Identification
- Phone and charger
- Book or tablet
- Headphones
- Comfortable sweater
- Snacks when permitted
- Water or another approved beverage
- List of questions for your clinical team
Mercy Infusion’s ambulatory infusion suite is designed to provide a comfortable setting for physician-directed treatment.
What Happens When You Arrive?
Your infusion professional may begin by reviewing:
- Your name and date of birth
- Prescribed treatment
- Current symptoms
- Recent health changes
- Medication allergies
- Previous infusion history
- Physician orders
Vital signs may be checked before treatment begins.
If anything has changed since your treatment was scheduled, tell your nurse.
For example:
- Fever
- New infection
- Recent hospitalization
- New medications
- New shortness of breath
- Significant swelling
- New rash
- Other meaningful health changes
The clinical team can determine whether the physician needs to be contacted before treatment proceeds.
Starting the IV
For intravenous treatment, access must be established unless the patient already has an appropriate physician-directed access device.
Many IVIG patients use a peripheral IV placed into a vein in the arm or hand.
The nurse will prepare the area and establish IV access before connecting the medication.
Patients who have difficult venous access should let the healthcare team know.
How IVIG Is Administered
IVIG is infused gradually.
The medication may begin at a slower infusion rate and increase according to the prescribed product instructions and physician-directed protocol when the patient tolerates treatment.
Infusion rate matters because some reactions may be associated with how quickly immune globulin is administered. FDA-approved immune globulin prescribing information includes product-specific infusion-rate precautions and monitoring requirements.
Your nurse monitors you during treatment and follows the prescribed protocol.
How Long Does the First IVIG Infusion Take?
There is no universal IVIG infusion time.
Treatment duration can depend on:
- IVIG product
- Dose
- Patient weight
- Prescribed infusion rate
- Whether it is the first treatment
- Previous treatment tolerance
- Medical conditions
- Whether the total dose is divided across multiple days
A first infusion may sometimes take longer because the care team is learning how the patient tolerates the medication.
Mercy Infusion advises patients that infusion duration varies according to the medication and treatment protocol.
Ask your team for an estimated duration before treatment day so you can plan accordingly.
What Might You Feel During the Infusion?
Many patients tolerate IVIG without significant problems.
However, symptoms can occur.
Depending on the specific product, potential infusion-related symptoms may include:
- Headache
- Fatigue
- Chills
- Nausea
- Dizziness
- Fever
- Flushing
- General discomfort
FDA prescribing information for immune globulin products identifies headache and other systemic symptoms among reported adverse reactions, while hypersensitivity reactions are a recognized risk of immune globulin treatment.
Tell your nurse promptly if something feels unusual.
Do not wait until the infusion ends to mention symptoms.
Serious Symptoms Require Prompt Attention
IVIG can rarely be associated with more serious complications.
Your healthcare team will provide instructions regarding symptoms that require medical attention.
Seek appropriate emergency care for severe or rapidly developing symptoms such as:
- Significant difficulty breathing
- Severe chest pain
- Loss of consciousness
- Signs of a severe allergic reaction
- Other symptoms that appear to be a medical emergency
Mercy Infusion advises patients experiencing side effects to notify the clinical team or physician and to seek emergency care for severe reactions.
What Happens After the Infusion?
After treatment, your nurse may:
- Recheck vital signs
- Remove or care for your IV access
- Review any symptoms
- Provide post-infusion instructions
- Document treatment
- Confirm follow-up plans
How patients feel afterward varies.
Some feel completely normal.
Others may experience fatigue, headache, or other temporary symptoms.
Follow your physician’s post-treatment instructions.
Should Someone Drive You Home?
Ask the clinical team before your first treatment.
Some patients may feel comfortable driving afterward, while others may prefer to arrange transportation until they know how IVIG affects them.
Factors such as premedication, treatment response, fatigue, dizziness, and underlying medical conditions may influence the decision.
Keep Track of How You Feel
After your first infusion, it can be helpful to note:
- How you felt during treatment
- Any symptoms after treatment
- When symptoms started
- How long they lasted
- Changes in your underlying condition
- Questions for your next appointment
This information can help your physician and infusion team understand your treatment experience.
Do not change your infusion schedule, dose, or medication independently.
What If the First Infusion Goes Well?
If IVIG becomes an ongoing treatment, subsequent infusions may feel more routine.
Depending on your medical condition and treatment plan, your physician may continue treatment:
- In an infusion suite
- At home
- In another appropriate setting
Eligible patients may eventually prefer home infusion because it reduces travel and allows treatment in a familiar environment.
Can Your First IVIG Infusion Be Given at Home?
Sometimes.
There is no universal requirement that every first IVIG dose must occur in an infusion center.
The appropriate site depends on:
- IVIG product
- Diagnosis
- Patient health
- Reaction risk
- Physician preference
- Required monitoring
- Insurance requirements
- Nursing availability
Some patients may begin treatment in a supervised infusion setting and later transition home.
Others may be clinically appropriate for home infusion from the beginning.
The prescribing physician and clinical team determine the appropriate setting.
