YOU and Your Doctor Are Your Medical Team – April 2026

Many of us take medications as part of everyday life. But taking medicine is not simply popping a pill into your mouth. It also means understanding what you are taking and why. There are several important things you should know about every medication you take.

What the medication is for — what condition it treats and how it helps your body.

Its name, including both the brand name and the generic name.

The correct dosage and how often it should be taken.

When to take it, including the best time of day and whether it should be taken with food, without food, or at a specific time in relation to meals.

How long you should continue taking it, and whether you should stop only under medical guidance.

Food restrictions, including any foods or beverages you should avoid while taking the medication.

Medication compatibility, meaning whether it can safely be taken with your other prescribed medicines, over the counter (OTC) drugs, vitamins, or supplements.

Possible side effects, including which symptoms should prompt you to contact your healthcare provider.

How to take it properly, such as by mouth, as eye drops, nasal spray, or another prescribed route.

This may sound like a lot to remember, but taking medication incorrectly can negatively affect your health and well-being.

Understanding Generic Names

Several pharmaceutical companies may produce essentially the same medication under different brand names. The generic name, which also appears on the container, identifies the active ingredients. If you have had a negative reaction to one company’s version of a medication, you will most likely react to another company’s product if it contains the same generic drug and ingredients.

Why Proper Medication Use Matters

Medicines can treat and even cure many health problems, but they must be taken correctly to be both safe and effective. Diet, other medications, and supplements or herbs can sometimes have a significant impact on how drugs work in the body. A drug interaction occurs when another substance changes the activity of a medication — increasing or decreasing its effects or causing an unexpected and possibly harmful reaction. These interactions often happen because people simply do not realize that certain combinations can be risky.

Always ask your healthcare provider whether there are foods, beverages, vitamins, or supplements you should avoid while taking your medications. For example, according to the National Institutes of Health, St. John’s wort, coenzyme Q10, and melatonin can interact with medications such as antidepressants, blood thinners, or alcohol. Other herbal supplements that may cause potential interactions include Asian ginseng, cat’s claw, chamomile, cranberry, ginkgo, goldenseal, and green tea, according to the National Center for Complementary and Integrative Medicine. This does not mean you should avoid herbs or supplements altogether. Instead, the goal is awareness. Be informed about possible negative effects when combining supplements with prescribed medications or when taking multiple OTC products at the same time.

Food and Medication Interactions

Not all medicines are affected by food, but many are influenced by what — and when — you eat. In some cases, taking medication with food changes how your stomach and intestines absorb it. Certain nutrients may bind with medication ingredients, reducing absorption or speeding elimination from the body.

Here are some common examples:

A. The acidity of fruit juice may reduce the effectiveness of certain antibiotics, such as penicillin.

B. Dairy foods and drinks may lower how well tetracycline and ciprofloxacin (Cipro) work when treating infections.

C. Green leafy vegetables such as kale and broccoli can affect warfarin, a blood-thinning anticoagulant.

D. MAO inhibitor antidepressants should not be combined with foods high in tyramine, including beer, red wine, chocolate, processed meats, avocados, certain cheeses, sauerkraut, kimchi, pickled vegetables, tofu, miso, and soy sauce.

E. Grapefruit juice can interfere with some blood pressure medications, organ-transplant medicines, and certain cholesterol-lowering drugs by changing how they break down in the body.

F. Alcohol can alter medication absorption, increasing or decreasing how well many medicines work. It may also affect insulin or oral diabetic medications, prolonging their effects and leading to low blood sugar. Pain relievers containing acetaminophen should never be taken with alcohol because of the increased risk of severe liver damage.

G. Grapefruit juice can also alter how the body absorbs statins (cholesterol-lowering drugs such as Lipitor), causing higher-than-normal drug levels and increasing the risk of side effects. Calcium channel blockers used for high blood pressure may be affected in a similar way, potentially raising drug levels in the bloodstream.

H. Licorice may seem harmless, but if you are taking Lanoxin (digoxin) for congestive heart failure or abnormal heart rhythms such as atrial fibrillation, certain forms of licorice may increase the risk of toxicity. Licorice may also reduce the effectiveness of blood pressure medications or diuretics (water pills).

The most important message is simple: educate yourself about the medications and supplements you take. You and your doctor are partners — a medical team — working together to protect and improve your health.
