All the drugs given as part of Atavistic Chemotherapy are FDA approved and have been safely used in medical practice for decades. None of them are experimental drugs, and we obtain them from around the world for use in the atavistic treatment regimen. We use these drugs in the treatment of cancer under the well-accepted “off-label” medical practice (see below).

The drugs used in combination have been selected based on the principles of "Atavistic Metamorphosis" published by Dr. Arguello in 2011, and after years of testing them in hopeless cancer patients. They fall in the pharmaceutical group of antibacterial (antibiotic), antifungal and antiprotozoal (antiparasitic) drugs. Antiviral drugs also have a place within the principles of Atavistic Chemotherapy because viruses preceded cells in their origin, and they were the precursors of the first cells on this planet. However, costs and toxicity of antiviral drugs have forced us to use them only when other approaches fail.

Although the drugs we use have been around for many years, Atavistic Chemotherapy and Immunotherapy is a new type of cancer treatment. A reason for not divulging the names of the medications is to prevent patients from self-medicating. It also prevents well-meaning caregivers from misusing drugs they are not familiar with in the treatment of cancer.

However, these cautions don't mean that patients are left in the dark. All patients undergoing Atavistic Chemotherapy are informed of the drugs they are receiving.

Atavistic Chemotherapy is intended for 6 to 12 months of daily treatment. The longevity of treatment better ensures that all cancer cells have been eliminated by the end of therapy.  All medications are taken orally.

The term "off-label use" refers to the prescribing of a drug that is approved for one use, but is used to treat a different disease. Off-label use of medications is not unusual. The use of minocycline is a good case in point. Minocycline is an antibiotic that can kill bacteria found on the skin. It is approved for, and commonly used in the treatment of acne vulgaris in teenagers. Minocycline was later found to have many other beneficial uses, including the treatment of mental diseases such as schizophrenia, or to protect nerve cells after a stroke.  Minocycline has not been FDA-approved for all of these purposes, per se, but once a drug is approved for use in humans, its use in the treatment of other diseases is left to the discretion of doctors.
