NOTE: The following pages identify which nutrients are depleted by specific types of drugs. You will also want to refer to the Nutrient–Drug Interaction Page to explore many other interactions. The principal benefit of this page is that they list “brand names” for drugs as well as their “generic” names.
You will also find value at the Drug-Nutrient Interactions & Depletions Page. Sadly, this site doesn't sort drugs by their brand name... for example, you'd need to know that Zoloft was actually called Sertraline if you wanted complete information.
NOTE: No single website provides all that information for free, but by using all 3 of these pages, you can gather the information you require.
If there are terms in these articles you don't understand, you can get a definition from the Merriam Webster Medical Dictionary. If you want information about a specific disease, you can access the Merck Manual. You can also search Pub Med for more abstracts on this topic..
Factors Contributing to Nutritional Deficiencies
From: “Symptomatology and Differential Diagnosis”
By Richard C. Schafer, D.C., FICC and the ACAPress
Several different factors may be involved in vitamin and mineral deficiencies. For example, abnormal loss, utilization or subnormal absorption, intake, storage, or transport, singularly or in combination, may readily lead to symptoms of nutritional deficiency. The following charts identify each condition.
A Practical Guide to Avoiding Drug-Induced Nutrient Depletion
Nutrition Review ~ October 2011
A little known, but potentially life-saving fact is that common medications deplete your body of a host of vital nutrients essential to your health. In this practical guide I’ll show you how to avoid drug-induced nutrient depletion and discuss options for replacing nutrient-robbing medications with natural supplements.
Recognizing Drug Induced Nutrient Depletion in Chiropractic Practice
The American Chiropractor ~ November 2009
Detrimental effects of drugs on nutrition status are a common occurrence but, because they usually occur over time (vs. what is considered an adverse event or allergic reaction, which occurs quickly), they are seldom recognized or corrected. Chiropractic treatment, however, takes place over a much longer time frame. Because of this, doctors of chiropractic are in a unique position to recognize the interactions of medication and nutritional status and, if knowledgeable in the area of drug induced nutrient depletion, they have an opportunity to help their patients recover nutritional adequacy and restore metabolic homeostasis.
Turning the Tables on Drug Interactions
As vitamin supplements and herbal remedies move to the mainstream, health care professionals are closely monitoring the interactions between natural products and drugs. However, understanding such biochemical interactions is no easy task. Vitamins and herbs clearly complicate the existing problems of drug interactions. Medical journals that are addressing vitamin, herb and drug interactions are using the watchword "caution" for those clinicians prescribing natural products in conjunction with pharmaceuticals.
Lancet 2000 (Jan 8); 355 (9198): 134-138
Concurrent use of herbs may mimic, magnify, or oppose the effect of drugs. Plausible cases of herb-drug interactions include: bleeding when warfarin is combined with ginkgo (Ginkgo biloba), garlic (Allium sativum), dong quai (Angelica sinensis), or danshen (Salvia miltiorrhiza); mild serotonin syndrome in patients who mix St John's wort (Hypericum perforatum) with serotonin-reuptake inhibitors; decreased bioavailability of digoxin, theophylline, cyclosporin, and phenprocoumon when these drugs are combined with St John's wort; induction of mania in depressed patients who mix antidepressants and Panax ginseng; exacerbation of extrapyramidal effects with neuroleptic drugs and betel nut (Areca catechu); increased risk of hypertension when tricyclic antidepressants are combined with yohimbine (Pausinystalia yohimbe); potentiation of oral and topical corticosteroids by liquorice (Glycyrrhiza glabra); decreased blood concentrations of prednisolone when taken with the Chinese herbal product xaio chai hu tang (sho-salko-to); and decreased concentrations of phenytoin when combined with the Ayurvedic syrup shankhapushpi. Anthranoid-containing plants (including senna [Cassia senna] and cascara [Rhamnus purshiana]) and soluble fibres (including guar gum and psyllium) can decrease the absorption of drugs. Many reports of herb-drug interactions are sketchy and lack laboratory analysis of suspect preparations. Health-care practitioners should caution patients against mixing herbs and pharmaceutical drugs.
