What Diseases Are Treated with Infusion Therapy

Written by Zachary Stratton, PharmD, CSP, IgCP

Infusion therapy treats chronic conditions like rheumatoid arthritis, Crohn’s disease, and immune disorders by delivering medications through IV. Available at infusion centers or at home, it ensures fast-acting relief when oral medications aren’t enough. Treatments include chemotherapy, immunotherapy, and hydration, with personalized treatment plans to manage conditions effectively.

If you’ve ever wondered what diseases are treated with infusion therapy, this blog can help provide answers. Infusion therapy plays a critical role in managing complex conditions that cannot be effectively treated with oral medications. Administered in infusion centers or at home, this therapy offers relief for people with complex medical conditions.

This article will explore common infusion therapy treatments and provide helpful insights into how infusion therapy works.

What Is Infusion Therapy?

Infusion therapy involves administering medication directly into the bloodstream through intravenous (IV) methods. It’s often prescribed for patients whose conditions don’t respond to oral medications, require faster-acting drugs, or for whom an oral medication is unavailable.

The types of infusion therapy include:

  • Antibiotics
  • Immunotherapy
  • Nutrition therapy
  • Monoclonal antibodies
  • Antibiotic therapy
  • Chemotherapy

What Conditions Are Treated with Infusion Therapy?

Many complex, rare, and ultra-rare conditions require infusion therapy for effective management. Below are some conditions treated using this therapy. For a more extensive list, please visit our Therapeutic Expertise areas to learn about the various conditions that infusion therapy treats.

Rheumatoid Arthritis

Rheumatoid arthritis is an autoimmune disease that attacks the joints, leading to pain and inflammation. Infusion therapy offers relief through biologic medications that help suppress the immune system’s overactivity.

Depending on the patient’s treatment plan, these treatments are typically done at infusion centers or at home.

Crohn’s Disease

Patients with Crohn’s disease experience severe inflammation in the digestive system. This leads to abdominal pain, diarrhea, and other complications. Infusion therapy can include immunosuppressants or anti-inflammatory medications to help manage the symptoms and prevent flare-ups.

Neurological Conditions

For patients with diseases like multiple sclerosis, Alzheimer’s disease, Guillain-Barre Syndrome, myasthenia gravis, and migraines, infusion therapy provides medications to manage symptoms and slow disease progression. This treatment helps with nerve pain and muscle control, offering a better quality of life.

Immune System Disorders

Infusion therapy is vital in treating immune system disorders, including primary immunodeficiency. It delivers immunoglobulin therapy, which replaces missing antibodies, helping the body fight infections effectively.

How Does Infusion Therapy Fit into Treatment Plans?

Infusion therapy may play a vital role in your healthcare provider’s overall treatment plan. Therapy often requires a long-term treatment plan when dealing with a chronic or complex illness. Infusion therapy offers a consistent way to administer medications that improve or stabilize the patient’s health.

Here’s how infusion therapy supports your treatment:

  • Efficient medication delivery: Medications work faster through IV administration than oral alternatives.
  • Individual treatment plans: Infusion therapy is tailored to each patient’s condition and health needs.

Where Are Infusion Therapy Treatments Administered?

Treatment depends on the condition; infusion therapy can be provided at different locations.

Infusion Centers

Many patients visit infusion centers or suites for outpatient treatment. These centers are designed for comfort and convenience, offering reclining chairs, free Wi-Fi, and refreshments. The professional care nurses provide ensures safe medication delivery and monitoring for side effects.

Home Infusion Therapy

Some patients with conditions impairing movement or abilities, or who have transportation challenges, may opt for home infusion if their therapy is approved or appropriate for home infusion. This allows them to receive treatment without disrupting their daily routines. Nurses will administer medications and monitor the patient’s response to therapy in the home.

Common Side Effects of Infusion Therapy

While infusion therapy is generally safe, side effects from the medication may occur. These may vary depending on the infusion treatment and patient response and are reviewed before treatment. Medications may be ordered by your provider prior to treatment to reduce side effects. Common side effects include:

  • Fatigue
  • Headaches
  • Nausea
  • Dizziness
  • Pain or swelling at the infusion site

If side effects persist, the patient’s treatment plan may need adjustments. Your provider may order medications. Patients should communicate with their care team about any side effects they experience during or after treatment.

Is Chemotherapy and Infusion Therapy the Same?

Chemotherapy is a type of cancer treatment that uses drugs to kill or slow the growth of cancer cells. It can be delivered in various ways, but one common method is intravenous (IV) infusion through a vein.

Infusion therapy is a broader term referring to any treatment delivered directly into the bloodstream via a needle or catheter. Many infusion centers provide non-chemo infusions for chronic, rare, or complex conditions.

Why Infusion Therapy Is Important for Complex Conditions

Infusion therapy isn’t only about administering medication—it plays a critical role in managing, maintaining and/or improving conditions. It ensures medications are delivered directly to the bloodstream for maximum effectiveness, making it ideal for complex health needs.

Key Benefits of Infusion Therapy

  • Fast-acting relief by administering larger controlled amounts of medication.
  • Higher levels of medication are obtained, which is often beneficial when treating certain conditions
  • Tailored care with treatment plans designed to meet each patient’s unique needs.

The Bottom Line

Infusion therapy offers life-changing benefits for individuals with complex conditions, including rheumatoid arthritis, Alzheimer’s disease, multiple sclerosis and immune disorders. It ensures that essential medications are delivered quickly and effectively in an infusion center or in-home services.

Patients can make informed decisions about their care by understanding infusion therapy and how it fits into a complex, rare, or ultra-rare illness treatment. Whether you’re managing immune system challenges or seeking relief for neurological disorders, infusion therapy offers a reliable solution to help you live your best life.
