Drug Interactions

Many have the mistaken notion that all herbs and foods are safe to combine with medications because they are natural. However, everything you put in your mouth has the potential to interact since it travels the digestive system in similar ways to medications. Some drugs interfere with the body’s ability to absorb nutrients, and certain herbs and foods can speed up or slow down the action of a medication.
Interaction symptoms can include headaches, flu-like symptoms, increased anxiety, insomnia, nausea and some can be life threatening.
The team at Point of Return specialize in this field and know that an interaction can create unnecessary discomfort or pose a danger. Our program outlines herb, food and over-the-counter medications that may interact with Antidepressants, Benzodiazepines and Sleeping Pills. Each medication is listed in the Point of Return workbook with a list of Items to Avoid in your diet while on the program. And our Pocket Interaction Guid ein a compact size that includes Antidepressants, Benzodiazepines, Sleeping Pills and Anti-Psychotic medications.
Whether you are withdrawing from medications or not, it is critical to understand how many items can affect your prescriptions or heavily deplete the body. Below is just a sampling of items to avoid such as Passionflower, St. John’s Wort, 5-HTP, Caffeine, Barley Grass, Ginseng, Chinese Herbs and others. For a complete list of items to avoid, please review both the Point of Return workbook (not sold separately but included in the program) and the Pocket Interaction Guide, which is sold separately.
Some items such as artificial sweeteners should be avoided when possible, whereas specific herbs should be gradually tapered versus an abrupt discontinuation.
While vitamins are generally safe, they are regularly consumed without appreciating that some have the potential to interact with medications. Herbs are plant-derived drugs, and while many may be beneficial, they can also pose a serious risk when combined with various prescription pills.
Foods & Beverages
The risk of a drug interaction isn't limited to herbal supplements and over-the-counter medications. Certain foods can interact with various prescription pills.
Artificial Sweeteners & Flavorings
Many foods are laced with excitotoxins (toxins that affect the central nervous system) in the form of additives that cause brain cells to swell and die. Excitotoxins are included in beverages, artificial sweeteners and sauces. These compounds are often disguised as hydrolyzed vegetable protein, sodium caseinate, calcium caseinate, yeast extract, soy protein isolate, textured protein, and even natural seasoning and spices can be 12 to 40 percent MSG. Eliminating excitotoxins is essential to protect the brain, eyes, hypothalamus and the central nervous system. Even artificial sweeteners, sold as diet items, have actually been associated with weight gain. [1]
OVER-THE-COUNTER (OTC) MEDICATIONS
Whenever an over-the-counter item is taken with a prescription medication, there is a chance that there will be an interaction between them. The interaction may increase or decrease the effectiveness and/or the side effects and might also result in a new side effect that is not generally seen with the medications individually. The likelihood of drug interactions increases as the number of combinations increases. Most drug interactions are due to altered absorption in the intestine and can change the blood flow to the intestines, metabolism of the drug by the intestine, increased movement in the intestines resulting in diarrhea or constipation, alterations in the acidity of the stomach and a change in the bacteria of the gut region. The liver and kidney are where most drugs are eliminated and therefore are important sites of drug interactions. Drug interactions can be complex and unpredictable, so minimizing the risk is essential.
