Repurposed Drugs in Terrain-Based Cancer Care
Backed by science and personalized to your genetics and needs, repurposed drugs offer low-toxicity, high-impact support in your healing journey.
What Are Repurposed Drugs?
Repurposed drugs are medications originally developed for other conditions—like diabetes, infections, or inflammation—that also show benefits in fighting cancer. At CIOFM, we use them thoughtfully to support your body, disrupt cancer’s survival strategies, and reduce treatment side effects.
Well-Studied
Low Toxicity
Multi-Functional
Metformin – Disrupts cancer’s sugar-fueled metabolism
LD Naltrexone – Calms inflammation and boosts immune response
Mebendazole – Blocks cancer cell division and angiogenesis
Aspirin – Lowers cancer-promoting inflammation and clotting
Celebrex – Targets inflammatory pathways linked to cancer spread
Doxycycline – Disrupts mitochondrial function in cancer cells
Clarithromycin – Helps reduce chronic infections and biofilms
Ivermectin – Shows anti-cancer, anti-inflammatory, and immune-modulating effects
Examples of Repurposed Drugs Used at CIOFM
These medications are never one-size-fits-all. Dr. Jamie evaluates each patient's terrain, genetics, and treatment plan to determine if repurposed drugs are a good fit for your needs and goals.
We may also use specialized blood tests to help identify which repurposed drugs your specific cancer cells are most sensitive to, allowing us to tailor your treatment with greater precision and purpose.

Frequently Asked Questions
-
Yes. These drugs have long safety records and are often used in lower doses when repurposed for cancer. Dr. Jamie carefully evaluates your individual health profile to ensure safety and effectiveness.
-
Each one works differently, and their use is highly personalized.
Repurposed drugs can:
Disrupt cancer’s energy sources
Reduce chronic inflammation
Weaken cancer’s defenses
Support your immune system
-
No. They don’t replace conventional treatments—but they can enhance them. Repurposed drugs may improve treatment response, reduce side effects, and help protect healthy cells.
-
It depends on the medication and your insurance provider. Some are commonly prescribed for other conditions and may be covered. We can help you navigate this on a case-by-case basis.
-
No. While they may seem familiar, repurposed drugs for cancer care must be used intentionally and under medical supervision. Dr. Jamie will determine if they’re appropriate for your plan based on labs, genetics, and your terrain.
-
Conventional oncology often focuses on FDA-approved cancer protocols. While many repurposed drugs are backed by solid research, they’re not yet standard in all cancer care settings. CIOFM integrates both conventional and emerging therapies for a more comprehensive approach.
-
That’s a critical question—and one we always evaluate. Drug interactions are reviewed carefully before any new therapy is recommended, especially in complex cancer treatment plans.
-
Duration depends on the specific medication, your treatment phase, and your goals. Some are used short-term during chemotherapy, while others may be helpful long-term for recurrence prevention or metabolic support.
-
Yes, in some cases. Repurposed drugs may be used preventively or to support healing, detoxification, immune balance, and metabolic health after conventional treatment ends.
Supporting Research on Repurposed Medications
We align our approach with emerging research and clinical insight. The FLCCC's comprehensive paper, “Cancer Care” by Dr. Paul Marik, outlines a powerful case for the use of repurposed medications in integrative cancer therapy.
This resource highlights the scientific rationale, safety profiles, and promising outcomes of drugs like Metformin, Ivermectin, Mebendazole, and others that we may incorporate into your personalized care plan.
It supports the growing movement to rethink how familiar medications can be used in innovative ways to disrupt cancer metabolism and support the body’s natural defenses.
