What Is an In-Office Infusion Suite?
Some gastrointestinal conditions require medications that are delivered directly into the bloodstream rather than taken by mouth. An in-office infusion suite provides a convenient setting where you can receive intravenous (IV) medications while being monitored by trained healthcare professionals.
For people living with conditions such as Crohn's disease and ulcerative colitis, infusion therapy may be an important part of controlling inflammation and maintaining remission. An in-office setting allows your gastroenterology team to provide your treatment while continuing to monitor your condition and response to therapy.
Who May Benefit From Infusion Therapy?
Infusion therapy may be recommended when your treatment plan includes a medication that needs to be given through an IV. In gastroenterology, this may include biologic medications used to treat inflammatory bowel diseases such as:
- Crohn's disease
- Ulcerative colitis
- Other conditions that require prescribed IV medications or fluids
Not everyone with these conditions needs infusion therapy. Your gastroenterologist will consider your diagnosis, disease severity, previous treatments, overall health, and response to treatment when determining whether an infusion-based medication is appropriate for you.
What Happens During an Infusion?
When you arrive, the healthcare team will review your treatment plan and check your vital signs. An IV catheter is usually placed into a vein in your arm, and the prescribed medication is administered over a specified period.
The length of the infusion and the rate at which the medication is given depend on the specific medication. During your infusion, trained healthcare professionals monitor you for possible reactions and may check your vital signs during and after treatment.
Once the medication has been administered and the recommended observation period is complete, the IV is removed and you can generally leave the office.
How Should I Prepare for My Infusion?
Preparation depends on the medication you are receiving. Before starting certain biologic therapies, you may need laboratory testing or screening. Your healthcare team may also review your medications, allergies, previous infusion reactions, infections, and vaccination history.
Follow any eating and drinking instructions provided by your healthcare team and bring an updated list of your medications.
Let your medical team know before your appointment if you have a fever, active infection, or other new symptoms. Depending on your condition and the medication being given, your infusion may need to be delayed.
What Can I Expect After My Infusion?
Most people can return to their usual activities after an infusion, depending on the medication and how they feel. Some people may experience temporary fatigue, headache, or mild discomfort.
Your healthcare team will let you know what symptoms to watch for after your infusion and when to contact the office. If your medication is given on a regular schedule, following the recommended infusion schedule is important for maintaining your treatment plan.
Is Infusion Therapy Safe?
Infusion therapy is routinely performed, but medications given through an IV can have potential side effects or reactions. Your healthcare team monitors you during treatment so that any concerns can be identified and addressed.
Possible complications include:
- Infusion reactions: Rash, itching, flushing, headache, or changes in blood pressure may occur during or shortly after treatment.
- Allergic reactions: Serious reactions are uncommon but may require immediate medical attention.
- IV-site complications: Bruising, irritation, swelling, or infection can develop around the IV site.
- Medication-specific side effects: Each medication has its own potential side effects and risks.
- Infection risk: Some medications used to treat inflammatory bowel disease can affect immune system function and may increase the risk of certain infections.
Your gastroenterologist will discuss the specific medication being prescribed, including its potential benefits, risks, and what you can expect during treatment.
