Healthy Living for Elders: Food Can Affect Your Medicines1

Paulina Wittkowsky2

Food can affect the way prescription and over-the-counter medicines work. This can cause unwanted effects. When taking certain medicines, some foods should be avoided.

ALCOHOL

Drinking alcohol when you are taking certain medicines can be very dangerous. Some drugs that are affected by alcohol are: acetaminophen (such as Tylenol™), antihistamines (such as Benadryl™), and ibuprofen (such as Motrin™).

Always ask your doctor or pharmacist if alcohol can affect the medicine you are taking!

GRAPEFRUIT JUICE

Grapefruit juice increases the effect of some medicines. It is best not to take medicine with grapefruit juice.

Drink grapefruit juice at least two hours after or before you take your medicine.

MILK

Some antibiotics, like tetracycline, should not be taken with milk.

VEGETABLES

Vegetables that contain vitamin K, such as spinach, kale, and Brussels sprouts, can reduce the effectiveness of blood thinners (such as Coumadin™).

TAKE WITH FOOD

Certain medicines should be taken with food. This can help prevent stomach irritation. Examples of these medicines are ibuprofen (such as Motrin™) and certain diuretics (such as Aldactone™).

* Ask your doctor or pharmacist for more information on how food can affect your medicines.
