How Grapefruit Juice Can Interfere With Medications

Taking Melatonin Correctly for Night Owls

With most drugs that are affected by grapefruit juice, the juice lets more of the drug enter the blood, says Shiew Mei Huang, Ph.D., of the FDA. When there is too much drug in the blood, you may have more side effects.

For example, if you drink a lot of grapefruit juice while taking certain statin drugs to lower cholesterol, too much of the drug may stay in your body, increasing your risk for liver and muscle damage that can lead to kidney failure.

Many drugs are broken down with the help of a vital enzyme called CYP3A4 in the small intestine. Grapefruit juice can block the action of intestinal CYP3A4, so instead of being metabolized, more of the drug enters the blood and stays in the body longer. The result: too much drug in your body.

The amount of the CYP3A4 enzyme in the intestine varies from person to person. Some people have a lot of this enzyme and others just a little. So grapefruit juice may affect people differently even when they take the same drug.

Although scientists have known for several decades that grapefruit juice can cause too much of certain drugs in the body, more recent studies have found that the juice has the opposite effect on a few other drugs.

Why this opposite effect? Instead of changing metabolism, grapefruit juice can affect proteins in the body known as drug transporters, some of which help move a drug into our cells for absorption. As a result, less of the drug enters the blood and the drug may not work as well, Huang says.

Special Precautions & Warnings

Pregnancy and breast-feedingPOSSIBLY UNSAFE

Not enough is known about the safety of using melatonin when breast-feeding. It is best not to use it.

Children: Melatonin is POSSIBLY SAFE when taken by mouth as a single dose. It is POSSIBLY UNSAFE when taken by mouth or injected into the body in multiple doses in the short-term. Because of its effects on other hormones, melatonin might interfere with development during adolescence.

Blood Tests That Require Fasting

Some blood tests will require you to fast completely beforehand. In these cases, your medical practitioner will instruct you not to eat or drink anything, except water, in the hours leading up to the test. It is important that while fasting you continue to drink water as this will help keep your body and your blood hydrated and thus, easy to obtain a blood sample.

Not eating before some blood tests are carried out is crucial to making sure that the results of the blood test are correct and accurate. The core ingredients such as protein, vitamins and so forth, that essentially all of our food and drink are made of can have an effect on the reading of the levels of your blood which could have a fundamental effect on the results meaning a wrongful diagnosis or extra testing may come about as a result of this.

You will not have to do this for every blood test, not all blood tests need a fasting element before they are commenced. Blood tests that will likely require the need to fast for include

  • Renal function panel
  • Lipoprotein panel

Dependant on what test you are having will determine how long you need to withhold food for. Most blood tests that require a fasting element will expect the patients not to have anything but clear water for eight to nine hours before and leading up to the blood being taken. In terms of some blood tests, the patient will be required to not consume anything for a longer period, which is usually up to twelve hours.

What To Know About Aspirin

Before recommending a daily aspirin, doctors weigh the potential benefits against the risks, which, according to the Mayo Clinic, include:

  • Bleeding stroke, caused by a burst blood vessel.
  • Bleedingin your digestive tract .
  • Allergicreaction.

The AHA advises against taking a daily aspirin without talking with your doctor first. Your doctor can weigh your individual risks and benefits and make a recommendation.

Dr. Yang says he typically recommends low-dose aspirin commonly sold in 81 milligram dosage for patients who take daily aspirin therapy. “It is just as effective as regular-strength aspirin in terms of reducing the risk of heart attack and stroke,” he says. “We don’t usually recommend higher-strength aspirin because it may increase the risk of bleeding, which we’re trying to avoid.”

For pain relief, you can also take ibuprofen, another over-the-counter medication, while taking a statin, says Dr. Yang. But, “similar to aspirin, it is a nonsteroidal anti-inflammatory medication and so, if taken in excess, can increase the risk of bleeding, can increase your blood pressure it can sometimes cause kidney damage.”

Many of these are contraindicated and can severely hurt you when used in conjunction with anesthesia, other medications, or while undergoing surgery. Furthermore, just because these products are derived from plants and are considered natural, many medications and drugs are actually considered dangerous.

Nothing is embarrassing when it comes to safety. This is your life be truthful with us!

Introduction Statins are widely used in the treatment and prevention of lipid metabolism disorders. They are generally well tolerated but not devoid of side effects. These include, among others, muscular symptoms, arthritis, headaches, gynecomastia. Myositis and rhabdomyolysis associated with increased activity of creatinine kinase and serum creatinine levels are rare but serious adverse events of statin therapy. The risk of these complications is increased in elderly patients with chronic diseases and in alcohol abusers.

In own study melatonin was used for this purpose because previous experimental studies had demonstrated that it protected liver against harmful effects of many toxic agents as well as the consequences of ischemia-reperfusion model.

An alternative metabolic pathway includes melatonin oxidation to N-acetyl-formyl-5- methoxykynuramine and N-acetyl-5-methoxykynuramine . The kynurenine pathway of melatonin metabolism leads to formation of a series of free radical scavengers.

The best approach for any condition is to begin with very low doses of melatonin. Keep the dose close to the amount that our bodies normally produce . You should only use the lowest amount possible to achieve the desired effect. Your doctor can help you determine the most appropriate dose for your situation, including how to increase the amount, if needed.
