DRUG-FOOD INTERACTIONS
RECOMMENDATIONS for PATIENT
EDUCATION

aggravate high blood pressure and can lower

Natural licorice should be avoided with all
antihypertensive medications. (Read food ingredient
labels for licorice root or licorice extract.)
CALCIUM CHANNEL BLOCKERS:
Norvasc (amlodipine)
Procardia (nifedipine)
Supplemental calcium may reduce the
effectiveness of calcium channel blockers.

calcium, two hours before or two hours after taking
Norvasc or Procardia.
ACE INHIBITORS:
Vasotec (enalapril)
Zestril/Prinivil (lisinopril)

Lotensin (benazepril)
Capoten (captopril)

Avoid salt and salty foods.
Avoid salt substitutes that contain potassium.
Caution with potassium supplements.
Alcohol should be avoided
May raise potassium levels.
Potassium supplements or salt substitutes containing
potassium should not be taken without consent from
MD.
Food high in fiber (such as bran) or pectin
(such as applesauce) may decrease the
absorption of digoxin.
Digoxin should be taken a few hours before or after
eating something high in fiber or pectin. Natural
licorice should be avoided.

DRUG – FOOD INTERACTIONS
DRUG
Coumadin (warfarin sodium)
DRUG-FOOD INTERACTIONS
RECOMMENDATIONS for PATIENT
EDUCATION
Foods high in Vitamin K may counteract the
blood thinning properties of this drug.
Advise patient to maintain consistent diet; patients on
Coumadin should not significantly vary the amount of
Vitamin K rich vegetables/foods in their diet from day
to day. Foods high in Vitamin K should be limited –
dark green leafy vegetables, spinach, kale, broccoli,
lettuce, turnips, cabbage, brussel sprouts, soybean
and vegetable oil, beef liver, raw cauliflower. Green
tea is also high in Vitamin K and may need to be
discontinued.
Aspirin
Can be irritating to the stomach
Take with food or milk. Avoid or limit the use of
alcohol.
Fosamax (alendronate)
Food or beverages other than water may
interfere with absorption of the drug. Tube
feedings or enteral supplements may
interfere with drug absorption.
Fosamax must be taken on an empty stomach at
least 30 minutes before eating or drinking anything
other than water (including other medicines or
vitamins). This medication should be taken with a full
glass (6-8 oz or 180 ml-240 ml) of plain water once
daily unless directed otherwise by MD. Advise patient
to swallow the tablets whole and not to chew or suck
on them. Tell patient not to not lie down for at least 30
minutes after taking this medication to prevent
esophageal irritation.
Dilantin increases the metabolism of vitamins
D and K; may cause folate-deficiency
anemia.
Dilantin doses should be administered at least two hours
before or two hours after an intermittent tube feeding or
ingestion of an enteral supplement. (If a patient is receiving
continuous enteral feedings, consult with healthcare
provider.). Eating generous amounts of milk, liver, dark
green, leafy vegetables may help replace the vitamins
destroyed by Dilantin.

DRUG-FOOD INTERACTIONS
RECOMMENDATIONS for PATIENT
EDUCATION
Sinemet (levodopa/carbidopa)
High protein meals may lead to a decreased
response to levodopa. Pyridoxine (Vitamin
B6) in doses of more than 5 mg/day may
reverse levodopa’s drug effectiveness.
It is best to be consistent on a daily basis as to when
Sinemet is administered with relationship to meals.
Avoid protein intake swings. Limit foods containing
Vitamin B6: avocado, bacon, beans, beef, liver, dry
skim milk, port, peas, sweet potato, and tuna.
Iron (ferrous sulfate, ferrous gluconate)
Eggs and milk decrease iron absorption.
Coffee and tea that is drunk with a meal or 1
hour after a meal may also decrease iron
absorption.
Do not administer with dairy products or eggs –
space two hours apart. Foods/beverages high in
Vitamin C may enhance absorption of iron: oranges
and orange juice, broccoli, strawberries, green
peppers, tomatoes, potatoes.
Synthroid (levothyroxine)
Certain foods may decrease absorption of
this medication when taken at the same time.
Some foods may interfere with thyroid
function.
Synthroid should be taken separately from: soybean
flour, walnuts, dietary fiber.
The following should be avoided: soybeans,
cabbage, turnips, brussel sprouts, kale and
rutabagas.
Grapefruit or grapefruit juice may increase
the serum concentration of these and other
MG-COA reductase inhibitors.
Eating grapefruit or drinking grapefruit juice should be
avoided unless otherwise instructed by MD.
CHOLESTEROL LOWERING
MEDICATIONS
Lipitor (atorvastatin)
ZOCAR (SIMVASTATIN)
POTASSIUM DEPLETING:
Avoid alcohol to reduce the risk of liver damage.
Increases potassium loss in the urine.
Maintain consistent consumption of foods high in
potassium such as organ meats, bananas, tomatoes,
cantaloupe, potatoes, spinach. Have potassium
levels checked regularly by healthcare provider.

Foods high in potassium should be avoided as well
as potassium supplements or salt substitutes
containing potassium.
Calcium and other minerals may decrease
absorption of Cipro and other
fluoroquinolones.
Take medication on an empty stomach or at least one
to two hours before or after a meal. Take antacids,
magnesium, calcium, iron or zinc supplements two
hours before or two hours after medication
