Part 1

Interactions by Drug

Some interactions may increase the need for the herb, other interactions may be negative and indicate the herb should not be taken without first speaking with your physician or pharmacist. Others may require further explanation. An asterisk (*) next to an item in the summary indicates that the interaction is supported only by weak, fragmentary, and/or contradictory scientific evidence. Refer to the individual drug entry for specific details about an interaction. The following list only includes the generic or class name of a medicine—to find a specific brand name, use the index.

Accuretic

Contains the following ingredients:

Hydrochlorothiazide (page 000)

Quinapril (page 000)

Acebutolol

Common names: Sectral

Combination drug: Secradex

Acebutolol is used to treat high blood pressure and certain forms of heart arrhythmia, and is in a family of drugs known as beta-adrenergic blockers (page 000).

Summary of Interactions for Acebutolol

In some cases, an herb or supplement may appear in more than one category, which may seem contradictory. For clarification, read the full article for details about the summarized interactions.

Depletion or interferenceNone known

Side effect reduction/preventionNone known

Supportive interactionNone known

Interactions with Dietary Supplements

Potassium

Some beta-adrenergic blockers (called “nonselective” beta blockers) decrease the uptake of potassium from the blood into the cells, leading to excess potassium in the blood, a potentially dangerous condition known as hyperkalemia. People taking beta-blockers should therefore avoid taking potassium supplements, or eating large quantities of fruit (e.g., bananas), unless directed to do so by their doctor.

Interactions with Herbs

Pleurisy root

As pleurisy root and other plants in the Aesclepius genus contain cardiac glycosides, it is best to avoid use of pleurisy root with heart medications such as beta-blockers.

Interaction with Foods and Other Compounds

Taking acebutolol with food slows the rate of absorption and reduces the maximum blood levels of the drug, though overall absorption is not affected. However, the blood level of an active breakdown product of acebutolol is reduced. Though the activity of acebutolol is affected by food, people taking the drug on a daily basis are not likely to experience a reduction in the effectiveness of the drug if it is taken with a meal.

Acetaminophen

Common names: 222 AF, Abenol, Acetab, Acet, Alisphene Forte, Alvedon, Anadin Paracetamol, APAP, Apo-Acetaminophen, Artritol, Atasol, Boots Children’s Pain Relief Syrup, Boots Cold Relief Hot Blackcurrant, Boots Cold Relief Hot Lemon, Boots Infant Pain Relief, Calpol 6 Plus, Calpol Infant, Calpol Pediatric, Calpol, Cephanol, Children’s Acetaminophen, Children’s Feverhalt, Cupanol Over 6, Cupanol Under 6, Disprol, Dom-Acetaminophen, Fanalgic, Fennings Children’s Cooling Powders, Hill’s Balsam Flu Strength Hot Lemon Powders, Infadrops, Lem-Plus Powders, Medinol, Novogesic, Pain Aid Free, Paldesic, Panaleve 6+, Panaleve Junior, Pandol, Panodol Baby and Infant, Paracetamol, Paracets, Paraclear, Paramin, Pediatrix, PMS Acetaminophen, Resolve, Robigesic Elixir, Rounox, Salzone, Tantaphen, Tempra, Tixymol, Tramil 500, Trianon, Tylenol, WestCan Extra Strength Acetaminophen, WestCan Regular Strength Acetaminophen

Acetaminophen is used to reduce pain and fever.

Unlike NSAIDs (nonsteroidal anti-inflammatory drugs) (page 000), it lacks anti-inflammatory activity. Acetaminophen is available by itself or in nonprescription and prescription-only combination products used to relieve pain and the symptoms associated with colds and flu.

Summary of Interactions for Acetaminophen

In some cases, an herb or supplement may appear in more than one category, which may seem contradictory. For clarification, read the full article for details about the summarized interactions.

Interactions with Dietary Supplements

N-acetyl cysteine (NAC)

Hospitals use oral and intravenous N-acetyl cysteine (NAC) to treat liver damage induced by acetaminophen overdose poisoning. NAC is often administered intravenously by emergency room doctors. Oral NAC appears to be effective for acetaminophen toxicity.

An uncontrolled trial compared intravenous NAC with oral NAC in children with acetaminophen poisoning and found that both methods were equally effective in reversing acetaminophen-induced liver toxicity. However, acetaminophen toxicity is a potential medical emergency, and should only be managed by qualified healthcare professionals.

Vitamin C

Taking 3 grams vitamin C with acetaminophen has been shown to prolong the amount of time acetaminophen stays in the body. This theoretically might allow people to use less acetaminophen, thereby reducing the risk of side effects. Consult with a doctor about this potential before reducing the amount of acetaminophen.

Interactions with Herbs

Hibiscus

One small study found that hibiscus could decrease levels of acetaminophen if the drug was taken after the tea was consumed though it was not entirely clear if the decreases were clinically significant.

Milk thistle (Silybum marianum)

Silymarin is a collection of complex flavonoids found in milk thistle that has been shown to elevate liver glutathione levels in rats. Acetaminophen can cause liver damage, which is believed to involve glutathione depletion. In one study involving rats, silymarin protected against acetaminophen-induced glutathione depletion. While studies to confirm this action in humans have not been conducted, some doctors recommend silymarin supplementation with 200 mg milk thistle extract, containing 70–80% silymarin, three times per day for people taking acetaminophen in large amounts for more than one year and/or with other risk factors for liver problems.

Schisandra (Schisandra chinensis)

Gomisin A is a constituent found in the Chinese herb schisandra. In a study of rats given liver-damaging amounts of acetaminophen, gomisin A appeared to protect against some liver damage but did not prevent glutathione depletion (unlike milk thistle, as reported above). Studies have not yet confirmed this action in humans.

Interactions with Foods and Other Compounds

Food

Food, especially foods high in pectin (including jellies), carbohydrates, and large amounts of cruciferous vegetables (broccoli, Brussels sprouts, cabbage, and others) can interfere with acetaminophen absorption. It is unclear how much effect this interaction has on acetaminophen activity.

Alcohol

Moderate to high amounts of acetaminophen have caused liver damage in people with alcoholism.10 To prevent problems, people taking acetaminophen should avoid alcohol.

Acezide

Contains the following ingredients:

Captopril (page 000)

Hydrochlorothiazide (page 000)

Actonorm Gel

Contains the following ingredients:

Aluminium

Dimethicone

Magnesium

Peppermint oil

Acyclovir Oral

Common names: Virovir, Zovirax Oral

Interactions with Dietary Supplements

Flavonoids

The flavonoids quercetin, quercitrin, and apigenin enhanced the antiviral activity of acyclovir in test tube studies. Controlled research is needed to determine whether taking quercetin or other flavonoid supplements would increase the effectiveness of acyclovir in humans.

Interactions with Herbs

Citrus species

The alkaloid citrusinine-1 from the root bark of citrus plants has been shown to enhance the antiviral activity of acyclovir. Further research is needed to determine whether taking citrus root bark would increase the effectiveness of acyclovir in humans.

Tripterygium wilfordii

Test tube studies show that triptofordin C-2 increases the antiviral activity of acyclovir against the herpes virus. Controlled human research is needed to determine whether taking tripterygium would increase the effectiveness of acyclovir in humans.

Other herbs

Animal studies have shown that other herbs, including Geum japonicum, Rhus javanica, Syzygium aromaticum, and Terminalia chebula enhance the antiviral activity of acyclovir. Controlled human studies are needed to determine whether taking these herbs would increase the effectiveness of acyclovir in humans.

Acyclovir Topical

Common names: Aciclovir Topical, Boots Avert, Herpetad, Soothelip, Viralief, Virasorb, Zovirax Topical

Acyclovir is an antiviral drug applied to the skin to treat the first outbreaks of genital herpes as well as herpes infections in people with poor immune systems. Topical application of acyclovir speeds up the healing process and the duration of pain.

Summary of Interactions for Topical Acyclovir

Interactions with Dietary Supplements

Minerals

Therapeutic amounts of intravenous salbutamol (albuterol) in four healthy people were associated with decreased plasma levels of calcium, magnesium, phosphate, and potassium. Decreased potassium levels have been reported with oral, intramuscular, and subcutaneous albuterol administration. How frequently this effect occurs is not known; whether these changes are preventable through diet or supplementation is also unknown.

Interactions with Herbs

Digitalis (Digitalis lanata, Digitalis purpurea)

Digitalis refers to a family of plants (commonly called foxglove) that contain digitalis glycosides, chemicals with actions and toxicities similar to the prescription drug digoxin (page 000).

In a small study of salbutamol (albuterol) in people receiving digoxin, albuterol was associated with decreased serum digoxin levels. No interactions between albuterol and digitalis have been reported. Until more is known, albuterol and digitalis-containing products should be used only under the direct supervision of a doctor trained in their use.

Coleus

A test tube study demonstrated that the bronchodilating effects of salbutamol (albuterol) were significantly increased by the addition of forskolin, the active component of the herb Coleus forskohlii. The results of this preliminary research suggest that the combination of forskolin and beta-agonists such as albuterol might provide an alternative to raising the doses of the beta-agonist drugs as they lose effectiveness. Until more is known, coleus should not be combined with albuterol without the supervision of a doctor.

Interactions with Foods and Other Compounds

Food

Albuterol may be taken with food to prevent stomach upset.

Aldactazide

Contains the following ingredients:

Hydrochlorothiazide (page 000)

Spironolactone (page 000)

Aldoclor

Contains the following ingredients:

Chlorothiazide (page 000)

Methyldopa (page 000)

Aldoril

Contains the following ingredients:

Hydrochlorothiazide (page 000)

Methyldopa (page 000)

Alendronate

Common names: Alendronic Acid, Biophosphonates, Fosamax

Alendronate is a member of the bisphosphonate family of drugs used to treat/prevent osteoporosis. It is also used to treat some bone diseases and some cases of cancer that have spread to bones.

Summary of Interactions for Alendronate

In some cases, an herb or supplement may appear in more than one category, which may seem contradictory. For clarification, read the full article for details about the summarized interactions.

Interactions with Dietary Supplements

Calcium

Calcium supplements may interfere with alendronate absorption. However, one researcher suggested that addition of large amounts of supplemental calcium to alendronate therapy in patients with bone metastases (with evidence of osteomalacia) related to prostate cancer might improve the clinical outcome. Moreover, both calcium and alendronate are commonly used in the treatment of osteoporosis in the same people. To prevent potential interactions, alendronate should be taken two hours before or after calcium

supplements.

Magnesium

Absorption of tiludronate, a drug related to alendronate, is reduced when taken with magnesium (page 000) and/or aluminum (page 000)-containing antacids. This interaction has not yet been reported with alendronate. Until more is known, alendronate should be taken two hours before or after magnesium and/or aluminum-containing antacids (page 000).

Interactions with Foods and Other Compounds

Food

Food, coffee, and orange juice significantly reduce absorption of alendronate.

Alendronate should be taken with a large glass of plain water, upon arising in the morning, and 30 minutes or more before any food, beverages, supplements, or other medications. People taking alendronate should remain upright (do not lie down) for 30 minutes after taking the drug.

Alfuzosin

Common names: UroXatral

Alfuzosin is used to treat the signs and symptoms of benign prostatic hyperplasia, also known as BPH. There are currently no reported nutrient or herb interactions involving alfuzosin.

Alka-Seltzer

Contains the following ingredients:

Aspirin (page 000)

Citric acid

Sodium bicarbonate (page 000)

Alka-Seltzer Plus

Contains the following ingredients:

Acetaminophen (page 000)

Pseudoephedrine (page 000)

Chlorpheniramine (page 000)

Allegra-D

Contains the following ingredients:

Fexofenadine (page 000)

Pseudoephedrine (page 000)

Allopurinol

Common names: Apo-Allopurinol, Caplenal, Cosuric, Lopurim, Rimapurinol, Xanthomax, Zyloprim, Zyloric

Allopurinol is a xanthine oxidase inhibitor used to prevent gout and to lower blood levels of uric acid in certain people taking drugs for cancer.

Summary of Interactions for Allopurinol

In some cases, an herb or supplement may appear in more than one category, which may seem contradictory. For clarification, read the full article for details about the summarized interactions.

May be Beneficial: Supportive interactionL-tryptophan

Vitamin D

Depletion or interferenceNone known

Side effect reduction/preventionNone known

Reduced drug absorption/bioavailabilityNone known

Adverse interactionNone known

Interactions with Dietary Supplements

Vitamin D

Individuals with gout have low blood concentration of the active form of vitamin D (1,25 dihydroxycholecalciferol), and allopurinol corrects this problem.1

L-carnitine

People who have Duchenne muscular dystrophy have low levels of L-carnitine in their muscles. Allopurinol restores L-carnitine to normal levels, resulting in improved muscle strength. Whether L-carnitine supplementation might improve this effect of allopurinol has not been investigated.

L-tryptophan

In a preliminary study, seven of eight individuals with severe mental depression showed improvement when they took L-tryptophan and allopurinol; of these seven, five experienced full remission. Controlled research is necessary to determine whether this combination might be more effective for severe depression than standard treatment.

Interactions with Foods and Other Compounds

Food

Allopurinol may be taken with food to prevent stomach upset.

Protein

Compared with people on high-protein diets, people on low-protein diets excrete less allopurinol, resulting in a threefold increase in the time it takes for the drug to be removed from the body. Vegetarians and those who eat low-protein diets (20 grams of protein a day or less) should discuss this possible interaction with their healthcare practitioner before taking allopurinol.

Alcohol

According to animal research, alcohol reduces the activity of antioxidant systems involving vitamin E, vitamin C, and selenium, leading to tissue damage in the cerebellum; however, allopurinol reverses this effect. Drinking alcoholic beverages also increases the removal of allopurinol from the body, thereby reducing the effectiveness of the drug. Therefore, people taking allopurinol should avoid alcohol.

5.0 out of 5 stars Excellent resource

D.W. · September 13, 2017

I am a "senior citizen" and subsequently am dealing with a number of age-related illnesses. I have excellent doctors but I do believe It is my responsibility to participate in my healthcare, including monitoring my many medications. Every time I get prescribed something new I question the doctor if it will conflict of any of my other meds. My pharmacist regularly runs the new script through a computer program to double check. I have been seeing a new specialist for a temporary illness; he prescribed a combination of some specific vitamins and said he was not aware of any conflict with my current meds. I checked with my pharmacist who informed me that one of the supplements did sometimes conflict with Warfarin. When shopping for the vitamins at 4 stores because no store carried all of them, the clerks all said there were no problems. No surprise, one clerk at a store that specializes in vitamins and supplements even said vitamins were "totally harmless." The last store was a health food store. After telling me that Warfarin was a statin, and arguing the point when I corrected her, I decided I was done. As I was leaving I asked her if she had any recommendations for resources I might use to find more specific information. She recommended the new revised A-Z Guide, which was out of stock at the store. Fortunately, Bolo had it and the rest is history! This long narrative is just to explain why this reference is important to have in my home and in the home of anyone who is taking a number of prescription drugs. I trust all of my doctors and they have never failed me. But I also believe it is up to me to ask questions and do the research when something doesn't seem right. The A-Z Guide explained the possible problem that the pharmacist mentioned regarding Warfarin AND provided the solution -- simply take them two hours apart. I am grateful to have found this excellent and thorough reference. The information is easy to understand and answers questions that the material provided by the drug companies does not.

5.0 out of 5 stars just what i needed

This book was mentioned in "The Metabolic Approach to Cancer" ... it is a perfect addition to my Nutritional Therapy practice. So far, I have found every drug I needed to find, and it a great to see easily the interactions and depletions. No complaints or regrets.

5.0 out of 5 stars A good book to have if you take RX's and supplenents

D.G. · September 12, 2022

I've been taking supplements for years, but just recently I was put on some prescription drugs and I wanted to make sure that I didn't have any interactions with my supplements. This book was a great reference and much easier than looking up all the different meds and supplements on the internet.

4.0 out of 5 stars Great to have, but room for improvement

R. · April 25, 2011

I'd seen this book in a couple of physicians' offices, and with the various meds my family takes as well as supplements, I thought it would be a good thing to add to the bookshelf. It is a nice reference to have to make sure that nothing you take, or take it with, is a dangerous combo. The fact that it includes what nutrients a drug or supplement or herb might interact with is worth the purchase alone. While the printout that comes with our prescriptions might list some dangers, they generally don't list all. It's nice to have a reference at hand to verify and hopefully prevent any complications. I also like that the contributors come from multiple medical disciplines.This book does, however, needs to be updated as it hasn't been revised since 2006 (though I may just not be finding the latest version). Many drugs and supplements have made it to market since then. Another wish would be to see this offered as well in a book maybe half the size - similar to the Merck Family Desk Reference. A large print version for those with visions issues might do well, also.

5.0 out of 5 stars A "Must Have" Reference for Patients and Doctors.

R.K.M. · March 24, 2000

The editors and authors of this HealthNotes publication have presented the most up-to-date information in an easy to read format without compromising scientific judgement. In the information world of alternative medicine, it is all to easy for conventional medical texts to react out of fear by recommending "extreme caution" for just about any prescription or possible nutrient/herbal interaction. "The A-Z Guide..." does a tremendous job of integrating insights of physicians form several different disciplines (the book is written by an MD, ND, and DC, et. al.), which provides the reader with a diverse and thorough scientific review of known and suspected interactions. I have personally found this book extremely helpful in the waiting room and on my desk as a quick refernce.

5.0 out of 5 stars Very Helpful Book!

D.H. · April 11, 2014

Everyone who takes any herbs or medications at all needs this book. It is easy to use and very complete in its listings, taking only a few minutes to check what you are taking against side effects and interactions. This book tells you things about your medications that even your doctor may not know. It has been very helpful to us in scheduling when to take different meds. Some things that interact negatively can work out perfectly if taken several hours apart. Try it, and you will be amazed. This little book just might save your life.
