What Is Infusion Therapy?
Infusion therapy is a way of giving medicine slowly through a vein (intravenously) over a set period of time while you are monitored. In gastroenterology, it is most often used for biologic medicines that treat moderate to severe Crohn’s disease and ulcerative colitis, and for intravenous iron when iron pills do not work or are not tolerated.
Infusion therapy involves administering medications or fluids directly into the bloodstream through a needle or catheter. At United Gastroenterology Associates, infusion therapy is utilized to manage various gastrointestinal conditions, such as inflammatory bowel disease (IBD), Crohn's disease, ulcerative colitis, and other autoimmune disorders affecting the digestive system. This specialized treatment approach allows for targeted delivery of medications that may not be effective through oral administration alone, aiming to reduce inflammation, control symptoms, and improve quality of life for patients.

What is infusion therapy used for in gastroenterology?
Infusion therapy is used to administer medications directly into the bloodstream to treat conditions such as:
Inflammatory Bowel Disease (IBD)
Inflammatory bowel disease (IBD), including Crohn's disease and ulcerative colitis.
Autoimmune Digestive Disorders
Autoimmune disorders affecting the gastrointestinal tract.
Severe or Treatment-Resistant Inflammation
Severe gastrointestinal infections or inflammation that do not respond to oral medications.
Iron-Deficiency Anemia
Intravenous iron for anemia caused by chronic gastrointestinal bleeding or poor absorption, especially when iron pills are not effective or not tolerated.
What medications are commonly administered through infusion therapy?
Common medications administered through infusion therapy for gastroenterology include:
Biologic Therapies
Biologic medicines target specific proteins involved in inflammation. Infliximab and vedolizumab are given by IV infusion, and some biologics, such as ustekinumab, start with an IV dose and continue as injections. Others, such as adalimumab, are injections given under the skin rather than infusions.
Immunomodulators
Immunomodulators to suppress the immune response and reduce inflammation.
Iron Infusions
Iron infusions for patients with iron deficiency anemia related to chronic gastrointestinal bleeding or malabsorption.
The medicine, dose, and schedule are chosen based on your diagnosis, disease severity, prior treatments, and insurance coverage.
What to Expect During Infusion Therapy
Before treatment starts, your gastroenterologist reviews your history and orders any required screening tests, such as tuberculosis and hepatitis B testing before many biologic medicines.
How is infusion therapy administered?
Infusions are given through an intravenous (IV) line by trained healthcare professionals in an infusion center or other appropriate clinical setting, which allows controlled and monitored administration. The office explains where your infusions will be given.
Is infusion therapy painful?
The infusion process itself is generally painless. Patients may experience mild discomfort during IV insertion, but this is temporary. Pain management techniques, such as numbing creams or warm compresses, may be used to minimize discomfort.
How long does an infusion therapy session take?
The duration of infusion therapy sessions varies depending on the medication being administered and the patient's individual treatment plan. Sessions typically range from 1 to 4 hours, with some biologic therapies requiring longer infusion times.
How often is infusion therapy needed?
The frequency of infusion therapy sessions depends on the specific medication, disease severity, and patient response to treatment. Some medications may require initial loading doses followed by maintenance infusions at regular intervals.
Are there any risks or side effects associated with infusion therapy?
Risks and side effects are generally minimal but may include:
Patients are monitored during and after each infusion so that reactions can be treated quickly. Some biologic medicines also lower the immune response, so your doctor checks for infections and recommends vaccines when appropriate.
When to seek emergency care
Call 911 for trouble breathing, swelling of the face or throat, chest pain, or fainting during or after an infusion.
Possible side effects
- Reactions to medications, such as infusion reactions (fever, chills, nausea).
- Localized irritation or redness at the infusion site.
- Rarely, more serious allergic reactions or infections, which are closely monitored and managed by healthcare providers.
Tell your care team about any fever, new symptoms, or signs of infection between infusions.
