2. NUTRITION-DRUG
INTERACTION

3. “A drug is taken to prevent or treat sickness
and disease”

4. Absorption
Distribution
Metabolism
Excretion

5. How Nutrient-Drug Interaction takes
place?

6. Food
Used by the body Energy
(nutrients)
the body is unable to use a nutrient due to a drug that
has been taken
Nutrient drug interaction

7. Adverse Effects of Nutrient-Drug
Interactions
Some drugs may affect the absorption of nutrients
Some foods, for example, those containing caffeine,
can amplify or modify the effects of certain drugs

8. DRUG
INDICATION
POSSIBLE EFFECTS

9. COUMADIN
Anticoagulant (blood thinner)

10. POSSIBLE EFFECTS

• Avoid dairy products for two to three
hours before and after taking the
medicine.

20. POSSIBLE EFFECTS
Antioxidants (Vitamin A, C, E, B, folic acid)
may interact with the drug by reversing its
effect.

21. LASIX
Diuretic (water-eliminating)

22. POSSIBLE EFFECTS
The Drug may decrease appetite thus
decreasing nutrient intake.

23. Impact of Food on Effectiveness of a
Drug
Nutrients in food may either delay absorption
into the body or speed up elimination from the
body, either or which can impact a drug's
effectiveness

24. The acidic ingredients in fruit juices are capable
of decreasing the power of antibiotics such as
penicillin

25. Many medications that are taken to
fight depression can be dangerous if mixed with
beverages

26. Impact of Drug on Nutritional
Status
Drugs may cause a increase or decrease in
appetite, leading to a increase or decrease in
nutrient intake
Nutritional status may also be impacted by a
drug's effect on the three main nutrients
Carbohydrates Fat Protein

27. A drug may speed up or slow down the breakdown of
these three nutrients, which are essential to the body's
functioning
When a drug affects the absorption of nutrients from food
into the body, less energy is available to be used by the
body

28. TIPS FOR AVOIDING INTERACTIONS
Be sure to read the label on a prescription medicine
and ask a pharmacist or physician if something is not
clear.
Always take medications with a full glass of water
Read all directions, warnings, and any possible side
