Managing gastrointestinal (GI) disorders often requires consistent and effective treatment to control inflammation, restore nutrient balance, and prevent flare-ups. While many patients begin with oral medications, others may benefit from intravenous (IV) therapy for faster, more targeted relief.
At Smart Infusion Therapy Services, we specialize in IV therapy and biologic infusions designed to support patients with conditions like Crohn’s disease and ulcerative colitis. With locations in Madison, Eau Claire, Wausau, and Onalaska, Wisconsin, our team provides safe, comfortable, and customized infusion care in collaboration with your gastroenterologist. We administer advanced therapies, including Entyvio for ulcerative colitis, Remicade, Stelara, and other biologic infusions that help control inflammation at the source.
If you’ve ever wondered how IV therapy compares to oral medications for managing chronic GI conditions, this guide breaks down the key differences, benefits, and when each approach may be right for you.
How IV Therapy Delivers Faster and More Targeted Relief
IV therapy works by delivering fluids, nutrients, or medications directly into your bloodstream, bypassing the digestive tract. This method offers complete bioavailability, allowing the body to absorb the full dose immediately. For patients with GI conditions, where inflammation, diarrhea, or malabsorption can limit nutrient and medication absorption, this is a major advantage.
In clinical settings, IV therapy is often used for hydration, nutrient replacement, or biologic infusions that help reduce gut inflammation. For instance, Entyvio for ulcerative colitis works by blocking specific immune cells from entering the GI tract, reducing inflammation without suppressing the entire immune system.
At Smart Infusion, every infusion is performed by trained nurses in private suites equipped with Wi-Fi, streaming access, and complimentary refreshments. Each session is carefully monitored to ensure comfort and safety from start to finish.
Key IV therapy benefits include:
- Rapid symptom relief: Medications act faster since they enter the bloodstream immediately.
- Improved absorption: Bypasses digestive barriers common in GI disorders.
- Targeted delivery: Biologic infusions can focus specifically on inflamed gut tissue.
- Customized treatment: IV to oral conversion plans are personalized for each patient’s needs.
The Limitations of Oral Medications for Certain GI Conditions
Oral medications are a convenient and common first-line treatment for many GI disorders. They are effective for mild to moderate symptoms and help maintain remission in many cases. However, they rely on the digestive system for absorption, which can be problematic for patients whose GI tract is compromised.
Conditions like Crohn’s disease or ulcerative colitis can cause inflammation in the intestinal lining, reducing how well the body absorbs nutrients and medications. This can lead to slower symptom relief, inconsistent results, and increased side effects from higher doses.
Additionally, patients who experience nausea, vomiting, or severe diarrhea may struggle to keep oral medications down, limiting their effectiveness.
Limitations of oral therapy include:
- Reduced absorption during flare-ups.
- Delayed relief for acute symptoms.
- Potential gastrointestinal irritation.
- Difficulty maintaining consistent medication levels.
When oral treatments no longer provide adequate control, IV therapy becomes a valuable next step, offering more predictable results and faster recovery.
When IV Therapy Is Recommended Over Oral Treatments
Not every patient with a GI disorder requires IV therapy, but for those with moderate to severe symptoms or poor response to oral medications, infusion therapy may provide the stability and relief needed to achieve remission.
IV therapy is commonly recommended when:
- Oral treatments are not tolerated or have failed.
- There is severe inflammation or active disease progression.
- Rapid symptom control is needed (such as dehydration or flare-ups).
- Nutrient deficiencies result from malabsorption or chronic diarrhea.
At Smart Infusion Therapy Services, therapies such as Remicade (infliximab), Stelara (ustekinumab), and Entyvio (vedolizumab) are administered following your gastroenterologist’s FDA-approved treatment plan. These biologic infusions work by targeting specific immune pathways to reduce inflammation and maintain remission, without the systemic side effects of long-term steroid use.
Our clinical team coordinates every step of your treatment plan, ensuring you receive precise, evidence-based care tailored to your unique health needs.
The Benefits and Drawbacks of Each Treatment Option
Both IV therapy and oral medications play important roles in managing GI disorders. The best option depends on your condition’s severity, how you respond to prior treatments, and your overall health goals.
IV Therapy
Benefits
- Provides immediate medication absorption into the bloodstream.
- Bypasses the GI tract, ideal for patients with inflammation or malabsorption.
- Allows for precise dosing and monitoring by trained clinical staff.
- Offers targeted delivery for conditions like Crohn’s disease and ulcerative colitis.
Drawbacks
- Requires visits to an infusion center.
- May cause mild infusion-site reactions, such as redness or soreness.
Oral Medications
Benefits
- Convenient to take at home.
- Generally more cost-effective for mild cases.
- Effective for maintenance therapy once symptoms are controlled.
Drawbacks
- May have limited absorption during flare-ups or active inflammation.
- Provides slower symptom relief compared to IV therapy.
- It can irritate the digestive tract, especially in sensitive patients.
In some cases, your provider may recommend a combination approach, starting with IV therapy for rapid control, then switching to oral maintenance once symptoms stabilize. This process, called IV to oral conversion, is often used in both infectious and inflammatory conditions to ensure consistent therapeutic results.
How Your GI Specialist Determines the Best Approach for You
Every GI condition is unique, and treatment decisions depend on multiple factors. Your gastroenterologist and infusion team will consider:
- Diagnosis and disease activity: Measured by lab work, imaging, and symptom tracking.
- Previous treatment response: Whether oral medications or biologics have been effective.
- Overall health and comorbidities: Including dehydration or anemia risk.
- Patient preferences: Comfort, lifestyle, and treatment goals.
At Smart Infusion, our nurses collaborate closely with your gastroenterologist to determine the safest and most effective therapy schedule. Whether you need Crohn’s disease infusion therapy, Entyvio for ulcerative colitis, or hydration-based IV support, our goal is to help you achieve lasting remission and improved quality of life.
Finding Balance: Choosing the Right Treatment for Long-Term GI Health
Both IV therapy and oral medications play an essential role in managing gastrointestinal conditions. While oral treatments are convenient for maintenance, IV therapy offers precise, fast-acting relief for those who need immediate or more powerful support. At Smart Infusion Therapy Services, we specialize in personalized IV infusion care for patients with Crohn’s disease, ulcerative colitis, and related GI disorders. Our licensed nurses and care coordinators ensure every session is safe, comfortable, and designed around your unique health goals.

Frequently Asked Questions
Is IV therapy better than oral medications for GI disorders?
It depends on your condition and how well you respond to oral treatment. IV therapy provides faster and more targeted relief for moderate to severe cases.
What is the IV to oral conversion?
It’s when treatment starts with IV medications for fast results, then transitions to oral forms for maintenance once symptoms improve.
Are IV antibiotics vs oral medications used for GI infections?
Yes. In some acute infections, IV antibiotics are started first for rapid control, then switched to oral once the patient stabilizes.
What are the main IV therapy benefits for GI health?
Faster relief, better absorption, and targeted inflammation control, especially for patients who don’t respond to oral therapies.
Is IV therapy safe?
When administered under medical supervision, IV therapy is a safe, effective, and evidence-based option for treating GI and autoimmune conditions.
