Albumin Infusion Side Effects and Reactions to Watch For

By Your Health Magazine Health Information Team

The possible side effects of albumin infusion include nausea, vomiting, fever, chills, flushing, headache, itching, rash, and changes in blood pressure or heart rate. More serious reactions include anaphylaxis, breathing problems, fluid overload, pulmonary edema, and heart or circulatory failure. Tell the nurse or doctor immediately about any new symptom during an infusion, especially hives, swelling, shortness of breath, or feeling faint.

Common Side Effects of Albumin Infusion

Human albumin is a protein solution given into a vein by a healthcare professional. It may be used to restore circulating blood volume or address specific medical problems involving low blood volume or low albumin. It is available in different concentrations, including 5% and more concentrated 20% or 25% formulations.

According to MedlinePlus information about human albumin injection, side effects that may occur include:

Nausea or vomiting
Fever or chills
Flushing or feeling unusually warm
Headache
Itching or increased sweating
Changes in blood pressure
A faster or slower heart rate

These symptoms can sometimes be related to the body’s response to the product or the rate at which it is being infused. Product labeling notes that some reactions improve when a healthcare professional slows or stops the infusion. Patients should not attempt to adjust an IV themselves.

Serious Reactions to Watch For

Possible reaction	Warning signs
Severe allergic reaction	Hives, widespread rash, itching, swelling of the face or mouth, trouble swallowing, wheezing, difficulty breathing, dizziness, or fainting
Fluid overload or pulmonary edema	New or worsening shortness of breath, unusual breathing sounds, rapidly increasing blood pressure, headache, or visible neck-vein swelling
Heart or circulatory problems	Very fast or slow heartbeat, low blood pressure, confusion, loss of consciousness, or rapidly worsening weakness

Allergic and Anaphylactic Reactions

Albumin can cause hypersensitivity reactions that may progress to anaphylaxis. Warning signs include hives, an itchy rash, swelling of the face, mouth, tongue, or throat, and difficulty breathing or swallowing. A rapid or irregular heartbeat, falling blood pressure, and loss of consciousness can occur in a severe reaction.

Sudden lip swelling during an infusion should be reported immediately, particularly if it occurs with hives or breathing symptoms. A single localized lip bump may have other explanations; this overview of common causes of unexpected lip bumps explains some distinctions. However, any new mouth or lip symptom that appears during albumin treatment needs prompt attention from the infusion team.

Fluid Overload and Breathing Problems

Albumin draws and retains fluid within the circulation. If the amount or infusion rate is not appropriate for a patient’s condition, blood volume may become too high. This is called hypervolemia. The excess fluid can strain the heart and, in severe cases, collect in the lungs as pulmonary edema.

The DailyMed prescribing information for Albumin (Human) 5% identifies pulmonary edema, cardiac failure, circulatory failure, and anaphylactic shock among the most serious reported events. The exact frequency of many reactions cannot be reliably calculated because some were reported voluntarily after products reached the market.

Who May Need Closer Monitoring?

Healthcare professionals normally assess a patient’s fluid status, medical history, and reason for treatment before and during albumin infusion. Extra caution may be appropriate for people with:

Heart failure or another condition that makes fluid overload dangerous
High blood pressure
Existing pulmonary edema
Severe anemia
Kidney problems, especially greatly reduced or absent urine production
Bleeding disorders or enlarged veins in the esophagus
A previous allergy or reaction to a human albumin product

Depending on the clinical situation, the medical team may monitor blood pressure, pulse, breathing, urine output, electrolytes, hemoglobin, hematocrit, and coagulation measures. Different albumin concentrations do not have identical fluid effects, so the product, amount, and infusion rate are selected for the individual medical situation.

What to Do If Symptoms Develop

Because albumin is generally administered in a hospital, clinic, dialysis center, or another supervised setting, help should be available if a reaction begins. During an infusion:

Report any new symptom immediately, even if it initially seems mild.
Do not wait for a rash, breathing problem, dizziness, or nausea to worsen.
Allow the clinical team to assess the IV, vital signs, lungs, and fluid status.
Tell the team if similar symptoms occurred with a previous infusion.

The clinician may slow or stop the infusion and provide appropriate treatment based on the suspected reaction. General information about recognizing and responding to medication side effects and allergic drug reactions can help patients understand why prompt reporting matters.

When to Seek Care

Seek emergency care for trouble breathing, wheezing, swelling of the tongue or throat, fainting, loss of consciousness, or rapidly worsening symptoms. If these problems begin after leaving a medical facility, call 911 in the United States rather than attempting to drive yourself.

Contact the treating healthcare professional promptly for persistent fever, chills, vomiting, rash, itching, unusual heartbeat, worsening swelling, or new shortness of breath after an infusion. A doctor, infusion nurse, pharmacist, or the specialist managing the underlying condition can review whether the symptom may be related to albumin or requires another evaluation.
