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.

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

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

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

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

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)
