Immunotherapy vs Homeopathy: What's the Difference?

Last updated
April 15, 2025

Parents seeking treatment for their child's allergies often encounter various terms and approaches, including "immunotherapy" and "homeopathy." These two treatments are sometimes confused, but they represent fundamentally different approaches with very different levels of scientific evidence and medical acceptance.

What is allergy immunotherapy?

Allergy immunotherapy, sometimes called "allergy vaccines" or "desensitisation," is a medical treatment that gradually exposes the immune system to increasing amounts of an allergen. This controlled exposure helps the immune system build tolerance, reducing allergic symptoms over time.

Modern immunotherapy works through several scientifically established mechanisms:

     
  • Modifying the immune response to allergens
  • Increasing protective antibodies (IgG4) that block allergic reactions
  • Reducing the activity of cells involved in allergic inflammation
  • Creating long-term changes in how the immune system recognises allergens

This approach is supported by extensive scientific research, including large-scale clinical trials demonstrating its effectiveness for many environmental allergies and increasingly for food allergies.

The science behind immunotherapy

Allergy immunotherapy is firmly grounded in scientific evidence and follows rigorous standards:

Standardised formulations

Immunotherapy products contain:

     
  • Precisely measured amounts of specific allergens
  • Standardised extracts with consistent potency
  • Known concentrations of major allergenic proteins
  • Pharmaceutical-grade ingredients that meet regulatory standards

Evidence-based protocols

Treatment follows established protocols:

     
  • Starting with small doses and gradually increasing
  • Building up to a therapeutic dose known to provide benefit
  • Maintaining regular administration over time (typically 3-5 years)
  • Monitoring for and managing any adverse reactions

Scientific validation

Immunotherapy has been validated through:

     
  • Randomised controlled trials with thousands of patients
  • Long-term effectiveness studies
  • Mechanistic research explaining how it works
  • Regulatory approval processes in multiple countries

Forms of evidence-based immunotherapy

Modern immunotherapy is delivered through several methods:

Subcutaneous immunotherapy (SCIT)

Traditional allergy shots involve:

     
  • Regular injections of allergen extracts
  • Administration in a medical setting
  • Gradual increase to a maintenance dose
  • Well-established effectiveness for respiratory allergies

Sublingual immunotherapy (SLIT)

Newer under-the-tongue treatments include:

     
  • Drops or tablets containing allergen extracts
  • Self-administration at home after initial medical supervision
  • Similar immune-modifying effects to injections
  • Approved products for grass, dust mite, and some tree pollen allergies

Oral immunotherapy (OIT)

For food allergies, emerging approaches include:

     
  • Carefully measured doses of allergenic foods
  • Gradual increase in amounts consumed
  • Medical supervision during dose increases
  • Protocol-driven approach to building tolerance

What is homeopathy?

Homeopathy is an alternative approach developed in the late 18th century based on two primary principles:

     
  1. "Like cures like" - the idea that substances causing symptoms in healthy people can treat similar symptoms in sick people
  2. "Law of infinitesimals" - the belief that higher dilutions (often beyond the point where no molecules of the original substance remain) produce stronger effects

The homeopathic approach

Homeopathic preparations typically involve:

     
  • Taking a substance that might cause symptoms similar to the condition being treated
  • Diluting it repeatedly, often to extreme degree
  • "Succussion" (vigorous shaking) between dilutions
  • Creating remedies with little to no measurable amount of the original substance

Key differences between immunotherapy and homeopathy

These approaches differ fundamentally in several critical ways:

Scientific approach to dosing

Immunotherapy: Uses carefully measured, standardised doses of allergens that gradually increase to therapeutic levels. The goal is to administer sufficient allergen to promote immune system changes while minimising risk.

Homeopathy: Employs extreme dilutions where more diluted remedies are considered more potent. Many homeopathic preparations are diluted to such a degree (beyond Avogadro's number) that they contain no molecules of the original substance.

Evidence base

Immunotherapy: Supported by extensive scientific research including:

  • Large randomised controlled trials
  • Meta-analyses showing consistent benefits
  • Studies demonstrating objective changes in immune markers
  • Approval by major regulatory bodies like the MHRA, EMA, and FDA

Homeopathy: Limited scientific support, with:

  • Few well-designed studies showing effectiveness beyond placebo
  • No established biological mechanism for how extreme dilutions could have therapeutic effects
  • Principles that conflict with fundamental concepts in chemistry and physics
  • Reviews by major health organisations generally concluding insufficient evidence for effectiveness in treating allergies

Regulatory oversight

Immunotherapy: Subject to strict pharmaceutical regulations regarding:

  • Manufacturing standards
  • Potency and consistency
  • Safety monitoring
  • Clinical trial requirements before approval

Homeopathy: Less rigorous regulatory requirements in many countries, often categorised differently from conventional medications.

Approach to allergies specifically

Immunotherapy: Directly addresses the underlying immune response by:

  • Targeting the specific proteins causing allergic reactions
  • Measuring immune changes during treatment
  • Demonstrating reduced sensitivity in objective challenge tests
  • Following protocols refined through decades of research

Homeopathy: Takes an individualised approach that:

  • Often doesn't directly address specific allergens
  • May vary significantly between practitioners
  • Lacks standardised protocols for allergic conditions
  • Doesn't typically involve objective measures of allergic sensitivity

The evidence for immunotherapy in allergic conditions

The scientific evidence supporting immunotherapy is substantial:

For respiratory allergies

Research consistently shows that immunotherapy:

  • Reduces allergy symptoms by 30–40% beyond medication alone
  • Decreases medication requirements
  • Provides benefits that continue after treatment stops
  • May prevent development of new allergies and asthma in children

For insect venom allergies

Venom immunotherapy has been shown to:

  • Reduce the risk of severe reactions by over 90%
  • Provide potentially life-saving protection
  • Offer long-lasting benefits after completion

For food allergies

Emerging evidence indicates that carefully conducted oral immunotherapy can:

  • Increase tolerance to previously reactive foods
  • Protect against accidental exposures
  • Significantly improve quality of life for many patients

Making informed treatment decisions

When considering treatment options for allergies, several factors are important to consider:

Consulting qualified specialists

Allergy specialists can:

  • Accurately diagnose specific allergies through appropriate testing
  • Recommend evidence-based treatments
  • Discuss the risks and benefits of immunotherapy
  • Monitor progress and adjust treatment as needed

Understanding the evidence

When evaluating any treatment, consider:

  • The quality and quantity of scientific studies
  • Whether claims made align with established scientific understanding
  • Recommendations from major medical organisations
  • The expertise and qualifications of those providing advice

Weighing risks and benefits

All treatments involve trade-offs:

  • Immunotherapy carries some risk of allergic reactions during treatment
  • However, it offers the potential for long-term reduction in allergy symptoms and medication use
  • The evidence supports these benefits for properly selected patients
