Allergy Medications and Cancer


Research published in Science News (1994;145:324) raises the question of whether the antihistamines for allergies be linked to cancer. Studies in mice have shown that antihistamines promote the growth of malignant tumors. Scientists at the University of Manitoba believe that the consumption of various medications, including antihistamines and antidepressants, may increase the risk for cancer. In February, 1994, the Department of Health and Human Services noted an increase in the incidence of cancer in the United States. Scientists at the University of Manitoba believe that the consumption of various medications, including antihistamines and antidepressants, may increase the risk for cancer and may be part of the reason for the increase. They have demonstrated that drugs like Elavil, Claritin, Hismanal, Atarax, Unisom, Prozac, NyQuil and Reactine have all created tumors in animal studies. Some antihistamines behave like the drug DPPE, which has been linked to enhancing tumor growth by binding to histamine receptors, which interferes with enzymes designed to detoxify and remove poisons from the body. This will also interfere with the system that regulates cell growth. The drugs do not necessarily cause cancer, but can enhance the growth of cancer.


So what can we do to address your allergies? Be definition of an allergen is an undigested protein that the body has reacted with. You need acid to digest proteins. Body pH must be addressed first and foremost. Antihistamines blocks your P-450 cytochrome which is involved with the bodies phase 1 and phase 2 detoxification process. If you block your livers detoxification process you shut down the immune system which may lead to cancer in some individuals. There are other medications that block the liver pathway and may create similar problems. Medications such as antibiotics, steroids, NSAID’s, pain medications, antacids, and some antidepressants have the same effect on the P-450 cytochrome ability to maintain phase1/2 detoxification. Individuals who can’t seem to get their immune system on track typically have a compromised immune system from a blocked liver pathway. I’ve found this to be a common problem when I run Organic Acid testing on them.

    In the case of poison ivy (mine is severe) antihistamine helps a little. What is missing in my body that would equal the antihistamine? Acid? If so, is acid aided by bile salts or what would be the remedy?

    Tecnu works great for poison ivy. We use natural anti histamines and proteolytic enzymes to get the swelling down. Alkaline environments in the body will make you more prone to a reaction. Apple cider vinegar has great pH properties to help keep that balance in the body and limited reactions.

    Fifteen years ago I was hopelessly hooked on Claritin. I had horrible allergies and took Claritin year round. When I decided I wanted to quit taking it on a permanent basis, it literally took more than a year of allergy symptom-induced sinus infections and many natural remedies to get everything balanced out. I have worked hard using various herbal tinctures, drinking green tea with nettle leaf and rinsing my nose daily with a Neti pot (with both salt and baking soda), but I now am completely medication free and have almost NO allergic responses to the many environmental items I previously experienced. Also, my immune system is so much stronger than it used to be. I’m a children’s librarian at a public library, and I rarely get sick anymore in spite of the many sniffling, sneezing, snotty kids I deal with every day. So I truly believe strengthening the immune system is the key to overcoming environmental allergies.

    Dr. Jeff, have you looked into the hypothesis that cancer may actually be an advanced fungal infection? These allergy medications suppress the immune system, allowing the fungus to thrive. Some doctors are even treating their cancer patients with anti-fungals like baking soda and they are having great success. I learned about this in the book Health Recovery Secrets. You can read the whole story on the author’s blog at Thank you and keep up the great work!

    Not all cancers are an Acidic problem. That’s highly misunderstood.

    Sugar feeds both cancer and fungal problems. Patients with a compromised immune system typically present with both.

    Thanks for that link. It certainly shows the risk in not taking a holistic approach to addressing cancer. Some doctors do seem to be having success with sodium bicarbonate treatments, when administered directly to the tumor. Personally, I believe that things like high-dose vitamin C and Rick Simpson oil are better choices of treatment. Neither requires any invasive treatments and can be taken orally for full effect. Rick Simpson oil has been shown to visibly cure skin cancer in as little as 4 days. I’m still investigating the cancer-fungus connection. One thing that seems too much of a coincidence, all of the natural anti-fungals I’ve researched are also potent anti-cancer compounds. I have more info on this but want to be brief here. I would encourage you to look into this further if you get the chance. Keep the good work there! Thanks.
