If you suffer from high blood pressure and have been prescribed Toprol, or metoprolol tartrate, there are some things you will need to consider. As with any medication, there are always possible side effects or interactions with other drugs, foods or vitamins and minerals. Knowing what medications you are taking, as well as how different foods can contribute to vitamin levels within your body, is very important and can reduce the risk of possible medication complications.
Toprol-XL, or its generic name metoprolol tartrate, is a medication known as a beta-blocker and is designed to treat high blood pressure. Toprol-XL is a once a day extended-release tablet and reduces the amount of pills you must take each day. Toprol-XL is made by the pharmaceutical company AstraZeneca. According to AstraZeneca, as a beta-blocker, Toprol-XL works to block chemicals such as adrenaline from attaching to receptor in your heart. By blocking adrenaline, which makes the heart work faster and harder, Toprol-XL is able to keep your blood pressure and heart rate under control.
Potassium and Toprol
Potassium is a mineral and electrolyte essential for cell function. Adults should receive 4,700 milligrams of potassium in their diets a day. Potassium can be found in a large variety of foods such as bananas and oranges. Beta-blockers like Toprol-XL are known to affect potassium levels and cause what is known as hyperkalemia, or elevated potassium levels. When you are taking Toprol, it is important to limit your potassium intake in order to prevent possible toxicity. Because of this interaction with the medication, you may be advised on certain dietary restrictions when taking Toprol.
Foods to Avoid
Because of the risk of hyperkalemia, your physician may require you to follow certain dietary restrictions when taking Toprol-XL. You may be advised to avoid foods high in potassium, so it will be important to make yourself aware of these foods. Foods such as bananas, potatoes, prunes and plums, oranges, tomatoes, raisins, artichokes, lima beans, acorn squash, spinach and almonds are some of the foods that contain large amounts of potassium and will more than likely need to be avoided.
When taking any medication, it is always important to consult with your physician and pharmacist regarding any possible interactions with foods, vitamin supplements or other medications. Because of the risk of hyperkalemia, or high potassium levels, while taking Toprol-XL, your physician will advise you on a recommended dietary plan that will avoid foods likely to contribute to high potassium levels. Following this restricted diet will be essential in maintaining optimal health and effectiveness of your medications and treatment.
