Some medicines need to be taken 'before food' or 'on an empty stomach'. This is because food can affect the way these medicines work.
For example, taking some medicines at the same time as eating may prevent your stomach & intestines absorbing the medicine, making it less effective. Alternatively, some foods can interact with your medicine, either by increasing or decreasing the amount of medicine in your blood to potentially dangerous levels or levels that are too low to be effective. Some foods can neutralize the effect of certain medicines. Some examples of foods or drinks which can interact with medicines include: grapefruit juice, cranberry juice, foods high in vitamin K such as leafy green vegetables, salt substitutes or food supplements high in potassium such as bananas. As a general rule, medicines that are supposed to be taken on an empty stomach should be taken about an hour before a meal, or two hours after a meal. Forgetting these instructions on rare occasions is unlikely to do any harm, but taking these medicines with food regularly may not work.
Question: I've been taking the same prescription medicine for years. Even though I'm careful to take the same amount as always, the medicine is not working like it did in the past. What is happening?
Answer: As you get older, normal changes happen in the body. You lose water & muscle tone. Also, our kidney & liver may not pass the drugs as quickly through our system as when we were younger. This means that many medicines act differently in older people. Medicine may take longer to leave your system. Talk to your doctor if you think the medicine is not working as it should.
Question: Why should I talk to my doctor about the remedies, vitamins & OTC (over-the-counter) medicines I take, along with my regular prescriptions?
Answer: It is very important to tell your doctor about all the medicines you take. Taking some OTC medicines with your prescription drugs can be downright dangerous. For example, you should not take aspirin if you are on warfarin.
Some OTC drugs can lead to serious problems if used too often or with certain other drugs. Combining drugs without talking to your doctor could make you sick. Over-the-counter (OTC) drugs are medicines sold directly to a consumer without a prescription, from a healthcare professional.
Question: I'm feeling sick & irritation in my stomach a lot, since I started my new pills. Some days I feel so sick I think about not taking the medicine. What should I do?
Answer: Talk to your doctor about any side effects you feel before you stop taking the medicines. Your doctor may have tips that can help, such as eating a light snack with your pills. You may talk to your doctor about switching to a new medicine.
Question: What does it means, to take medicines on an empty stomach?
Answer: Taking medicines on an empty stomach means that you should take your pills 2 hours before you eat or 2 hours after you eat.
