People taking digoxin should avoid Black licorice (which contains the ingredient glycyrhizin). Together, they can produce irregular heart rhythms and cardiac arrest; licorice and diuretics will produce dangerously low potassium levels, putting a patient at risk for numbing weakness, muscle pain and even paralysis. Licorice can also interact with blood pressure medication or any calcium channel blockers.
Aged cheese (brie, parmesan, cheddar and Roquefort), fava beans, sauerkraut, Italian green beans, some beers, red wine, pepperoni and overly ripe avocados should be avoided by people taking MAO antidepressants. The interaction can cause a potentially fatal rise in blood pressure.
And because Saint Johns Wort contains the same properties as these MAO antidepressants, it stands to reason that people ingesting the herb should avoid these same foods.
Grapefruit juice interacts with calcium channel blockers (including Calan, Procardia, Nifedipine, and Verapamil), cholesterol control medications, some psychiatric medications, estrogen, oral contraceptives and many allergy medications (Seldane, Hismanal). The juice modifies the body's way of metabolizing the medication, affecting the liver's ability to work the drug through a person's system. More Information.
Orange juice shouldn't be consumed with antacids containing aluminum. 'The juice increases the absorption of the aluminum. Orange Juice and milk should be avoided when taking antibiotics. The juice's acidity decreases the effectiveness of antibiotics, as does milk.
Milk also doesn't mix with laxatives containing bisacodyl (Correctol and Dulcolax). You might find the laxative works a little "too well" in the morning.
Large amounts of oatmeal and other high-fiber cereals should not be eaten when taking digoxin. The fiber can interfere with the absorption of the drug, making the act of swallowing the pill a waste of time.
However, don't stop eating your cereal right away, because that could cause digoxin levels in your system to soar to toxic levels. A professional should make the dietary changes after carefully examining the digoxin levels.
Leafy green vegetables, high in vitamin K, should not be taken in great quantities while taking Coumadin. These vegetables could totally negate the affects of the drug and cause blood clotting.
Caffeinated beverages and asthma drugs taken together can cause excessive excitability. Those taking Tagament (Simetidine), quinolone antibiotics (Cipro, Penetrex, Noroxin) and even oral contraceptives should be aware these drugs may cause their cup of coffee to give them more of a Java jolt than they expected.
Grilled meat can lead to problems for those on asthma medications containing theophyllines. The chemical compounds formed when meat is grilled somehow prevent this type of medication from working effectively, increasing the possibility of an unmanageable asthma attack.
Regularly consuming a diet high in fat while taking anti-inflammatory and arthritis medications can cause kidney damage and can leave the patient feeling, drowsy and sedated.
Alcoholic beverages tend to increase the depressive effects of medications such as benzodiazepines, antihistamines, antidepressants, antipsychotics, muscle relaxants, narcotics, or any drug with sedative actions.
It's a good idea to not consume any alcoholic beverages, or at least scale way back, when taking prescription medications. Antioxidant and beta-carotene intensify alcohol's effect on the liver.
Other commonly used over-the-counter medications can cause interaction problems also.
Aspirin can modify the effectiveness of arthritis medications, strong prescription steroids and diuretics. Combining aspirin with diabetic medications can drop blood sugars to dangerous levels. Aspirin can also cause toxicity when taken with glaucoma and anticonvulsant (anti-seizure) drugs and cause bleeding episodes when combined with a blood thinner, like Coumadin.
Acetaminophen can also cause interaction complications when overused. Heavy drinkers who take acetaminophen for hangover relief risk liver damage. Taking high doses of acetaminophen with Coumadin can cause bleeding episodes.
Antacids taken with antibiotics, heart and blood pressure or thyroid medications can decrease drug absorption by up to 90 percent.
Over-the-counter antihistamines - sold under the names Actifed, Theraflu, Dimetapp, Benadryl and Comtrex should be avoided if you are taking antianxiety or antidepressant medications.
Oral contraceptives are less effective when taken with barbiturates, antibiotics, anti-fungal or tuberculosis drugs.
Turnips contain two goitrogenic substances, progoitrin and gluconasturtin, which can interfere with the thyroid gland's ability to make its hormones. Although moderate consumption of goitrogens is not a hazard for healthy people, they can promote development of a goiter (an enlarged thyroid) in persons with thyroid disease.
Tomato contains small quantities of a toxic substance known as solanine that may trigger headaches in susceptible people. They are also a relatively common cause of allergies. An unidentified substance in tomatoes and tomato-based products can cause acid reflux, leading to indigestion and heartburn. Individuals who often have digestive upsets should try eliminating tomatoes for 2 to 3 weeks to see if there is any improvement.
Strawberries, Raspberries, Spinach, and Rhubarb: These contain oxalic acid, which can aggravate kidney and bladder stones in susceptible people, and reduce body's ability to absorb iron and calcium.
Raspberries contain a natural salicylate that can cause an allergic reaction in aspirin sensitive people.
The seeds from fruits such as Apple, apricot, and Quinces contain amygdalin, a compound that turns into Hydrogen Cyanide in the stomach. Eating large amount of seeds can result in cyanide poisoning.
Potatoes: Avoid potatoes with a green tint to the skin, and remove any sprouts; they will taste bitter and may contain solanine, a toxic substance that can cause diarrhea, cramps, and fatigue.
Plums, Peaches, Apricots, and Cherries: These fruits may produce allergic reaction in individuals with confirmed allergies to apricots, almonds, peaches, and cherries. People who are allergic to aspirin may also encounter problems after they have eaten plums or peaches as they contain salicylates. The pits of plums, peaches and apricots contain a compound called amygdalin. When consumed in large amounts, amygdalin breaks down into hydrogen cyanide, a poison.
Horseradish: Very high doses of horseradish can cause vomiting or excessive sweating. Avoid if you have hypothyroidism.
Turmeric: Should be avoided by persons with symptoms from gallstones.
