with Infusion Therapy
Living with Crohn’s disease means living with unpredictability — flares that disrupt your plans, pain that wears you down, and a constant awareness that your body isn’t working the way it should. If you’ve been fighting this battle for a while, you already know that managing Crohn’s is about more than managing symptoms. It’s about finding a treatment that gives you your life back.
For many Crohn’s patients, that treatment is biologic infusion therapy. Medications like Remicade, Inflectra, and Renflexis have transformed the way Crohn’s disease is treated — not just reducing symptoms, but actually healing intestinal damage and helping patients achieve long-term remission.
If your doctor has recently recommended a biologic infusion, you probably have questions. This guide covers everything you need to know: when doctors recommend infusion therapy for Crohn’s, how these medications work, what to expect during treatment, and how River’s Edge Specialty Pharmacy supports Crohn’s patients through every infusion.

When Do Doctors Recommend Infusion Therapy for Crohn’s?
Not every Crohn’s patient needs infusion therapy. Your gastroenterologist may recommend a biologic infusion if:
- Conventional treatments haven’t worked. If aminosalicylates, corticosteroids, or immunomodulators (like azathioprine or methotrexate) haven’t adequately controlled your symptoms, a biologic may be the next step.
- Your Crohn’s is moderate to severe. Biologic infusions are typically reserved for patients with moderate-to-severe disease activity — meaning significant symptoms, inflammation visible on imaging or endoscopy, or complications like fistulas or strictures.
- You need to reduce dependence on steroids. Long-term corticosteroid use carries serious side effects. Biologics allow many patients to taper off steroids while maintaining disease control.
- Your doctor wants to prevent further intestinal damage. Biologics don’t just suppress symptoms — they target the underlying inflammation and can promote mucosal healing, which is critical for preventing long-term complications like bowel obstruction or surgery.
- A “top-down” approach is appropriate. Some gastroenterologists now recommend starting biologics earlier in the disease course for patients with risk factors for aggressive disease, rather than waiting for conventional therapies to fail.
How Do Remicade, Inflectra, and Renflexis Work?
All three of these medications contain the same active ingredient: infliximab. Infliximab is a biologic medication classified as a TNF-alpha inhibitor. Here’s what that means in plain language.
When you have Crohn’s disease, your immune system produces excessive amounts of a protein called tumor necrosis factor-alpha (TNF-alpha). TNF-alpha drives the chronic inflammation in your intestines that causes pain, ulceration, diarrhea, and tissue damage.
Infliximab works by binding to TNF-alpha and neutralizing it — essentially blocking the signal that tells your immune system to keep attacking your intestinal lining. With the inflammatory signal turned down, your gut has the opportunity to heal.
| ⚠️ Good to Know: Remicade is the original brand-name infliximab. Inflectra and Renflexis are FDA-approved biosimilars — meaning they are clinically equivalent to Remicade in terms of safety and effectiveness. The choice between them often depends on your insurance plan’s formulary and your doctor’s recommendation. |
Remicade vs. Inflectra vs. Renflexis: What’s the Difference?
| Feature | Remicade | Inflectra | Renflexis |
| Active Ingredient | Infliximab | Infliximab-dyyb | Infliximab-abda |
| Type | Original biologic | Biosimilar | Biosimilar |
| FDA Approved | 1998 | 2016 | 2017 |
| Infusion Time | ~2–3 hours | ~2–3 hours | ~2–3 hours |
| Clinical Efficacy | Reference standard | Equivalent to Remicade | Equivalent to Remicade |
| Cost | Highest | Lower than Remicade | Lower than Remicade |
| Insurance Coverage | Widely covered | Preferred on some plans | Preferred on some plans |
From a clinical standpoint, all three medications work the same way and produce the same outcomes. The primary differences are cost and insurance preference. Your specialty pharmacy and doctor will work together to determine which option gives you the best coverage and lowest out-of-pocket cost.
How Often Will I Need Infusions?
Infliximab treatment follows a two-phase schedule:
Induction Phase (Weeks 0, 2, and 6)
You’ll receive three infusions over the first six weeks to build up the medication in your system. The first infusion is at week 0 (your starting appointment), the second at week 2, and the third at week 6. This loading schedule is designed to rapidly achieve therapeutic drug levels.
Maintenance Phase (Every 8 Weeks)
After the induction phase, you’ll transition to infusions every 8 weeks. This is the ongoing maintenance schedule that keeps the medication at effective levels in your body. Some patients may need adjusted timing based on their blood levels and clinical response.
| 💡 Pro Tip: Consistency is key with infliximab. Missing or delaying infusions can lead to reduced effectiveness and increase the risk of developing antibodies against the medication. Your specialty pharmacy will help you stay on schedule with reminders and proactive coordination. |
Can I Get Remicade Infusions at Home?
Yes — and many Crohn’s patients find home infusion to be a game-changer for their quality of life. Instead of traveling to a center every 8 weeks for a 2–3 hour appointment, a nurse comes to your home, sets up the infusion, monitors you throughout, and handles everything on-site.
Home infusion is typically an option for patients who have successfully tolerated at least their first few infusions at a center without significant reactions. Your doctor and specialty pharmacy will help determine when you’re ready to transition.
At River’s Edge, we offer both center-based and home infusion for Remicade, Inflectra, and Renflexis. Our care coordinators make switching between settings seamless.
What Are the Side Effects of Infliximab Infusions?
Like all medications, infliximab carries potential side effects. Being informed helps you recognize what’s normal and what requires attention.
Common Side Effects
- Upper respiratory infections (cold symptoms, sinus congestion)
- Headache
- Nausea or abdominal discomfort
- Fatigue
- Mild infusion reactions (flushing, itching, slight fever during or shortly after the infusion)
Less Common but Important Side Effects
- Infusion reactions: Some patients experience more pronounced reactions during the infusion, such as chest tightness, difficulty breathing, or significant flushing. Your nurse is trained to manage these and can slow or pause the infusion.
- Increased infection risk: Because infliximab modulates the immune system, patients may be more susceptible to infections. Report any signs of infection (fever, persistent cough, unusual fatigue) to your doctor promptly.
- Liver effects: Rare cases of liver inflammation have been reported. Your doctor will monitor your liver function through periodic blood tests.
Your clinical pharmacist at River’s Edge will review the full side effect profile with you before your first infusion and remain available to answer questions at any point during your treatment.
Frequently Asked Questions About Crohn’s Infusion Therapy
How does Remicade work for Crohn’s disease?
Remicade (infliximab) blocks TNF-alpha, a protein that drives chronic intestinal inflammation in Crohn’s disease. By neutralizing TNF-alpha, the medication reduces inflammation, relieves symptoms, and promotes healing of the intestinal lining.
What’s the difference between Remicade and a biosimilar?
Biosimilars like Inflectra and Renflexis contain the same active ingredient (infliximab) and are FDA-approved to be clinically equivalent to Remicade. They work the same way and produce the same outcomes, often at a lower cost.
How long does a Crohn’s infusion take?
A typical infliximab infusion takes about 2–3 hours. With check-in and post-infusion observation, plan for approximately 3–4 hours total for each visit.
Can I get Remicade infusions at home?
Yes. After your initial infusions at a center, many patients transition to home infusion. A trained nurse administers the medication at your home with the same safety monitoring and clinical oversight.
Will infliximab cure my Crohn’s disease?
Infliximab does not cure Crohn’s disease, but it can achieve and maintain remission, heal intestinal damage, and significantly improve quality of life. Many patients on infliximab experience long periods with minimal or no symptoms.
How long will I need to be on infusion therapy?
Many patients remain on infliximab long-term as maintenance therapy. The duration depends on your response, disease severity, and your gastroenterologist’s recommendation. Stopping treatment should only be done under medical guidance, as Crohn’s symptoms often return after discontinuation.
