Furosemide is a medication that is prescribed by healthcare providers for health conditions like high blood pressure and oedema (fluid retention). As a diuretic, furosemide helps your body get rid of excess fluid, which can alleviate swelling and help lower your blood pressure. While a lifesaver for many, you must be cautious about your diet when taking furosemide, as certain foods and beverages can reduce the medication’s effectiveness or lead to adverse effects. In this article, we’ll explore the foods to avoid when taking furosemide, how to maintain a balanced diet while on this medication, potential medication interactions, and essential dietary tips for individuals using furosemide.
Furosemide is a doctor-prescribed drug. It falls under the class of drugs known as loop diuretics, or water pills. Its main uses are to manage high blood pressure and swelling due to conditions like heart failure, liver disease, and kidney disease. It works by boosting urine production, helping your body remove extra fluid and salt. Thus can lower high blood pressure and ease fluid retention symptoms.
Furosemide acts on the kidneys, precisely on a part called the Loop of Henle. This part of the kidney’s nephron deals with reabsorbing water and salts from the urine into the body. Taking furosemide stops this process, by blocking the Na(+)-Cl (-)-2K (+) cotransporter leading to increase in the urine output, and removal of extra water and salt from the body. Lowering blood volume and blood pressure and reducing swelling are the results of this effect.
You can find furosemide in tablet form and liquid form. The dose of furosemide depends on the person and the medical condition to be managed. For managing oedema, adults typically start with 20 to 80 milligrams (mg) per day. It might be a single dose or broken down into two. Your doctor may adjust your dose based on your medical condition.
Furosemide, like other drugs, can lead to side effects in some people. Common side effects are dizziness, headache, blurred vision, feeling sick, diarrhoea, constipation, and excessive urination. More serious side effects can include severe body water loss, salt imbalances, inflammation of the pancreas, liver problems, and hearing loss or ringing in the ears (tinnitus). If you face any severe side effects while taking furosemide, consult your healthcare provider right away.
Did you know?
When you’re on furosemide, eating foods high in salt can reduce the drug’s effects. It can lead your body to hold onto more water. This can make fluid retention and high blood pressure worse. So, reducing salt intake is a must to let furosemide control your high blood pressure and relieve swelling. Be careful with the following kinds of foods.
Common processed foods, like soups in a can, chips, and meals you can store in a freezer, have excessive salt in them. Always check the label on food packets and choose options with less salt if you can.
Soups that come in cans often have salt added as a preservative. Try making soups at home or go for soups with less salt instead.
Snacks like salted nuts, pretzels, and crisps contain lots of salt. Switch to non-salted ones or other healthy snacks, like fresh fruits and vegetables.
Cheese can have a lot of salt, especially processed types, and hard cheeses. If you can, opt for cheeses with less salt.
Deli meats like cold cuts and sausages are typically high in salt. Go for fresh meats, poultry, or fish instead.
Fast food meals are famous for their high salt content. Think about making meals at home with ingredients that have less salt. Use herbs and spices to add flavor without adding salt.
Drinking moderate to high amounts of alcohol can interfere with the ability of furosemide to lower your blood pressure. It can even make it less effective. Alcohol can also make some side effects of furosemide worse, like dizziness. It’s best either to keep your alcohol intake low or to avoid it completely while taking furosemide.
Another beverage that must be monitored or avoided altogether is caffeine as it naturally has a diuretic action, if consumed a lot while on furosemide can increase side effects of furosemide like electrolytes imbalance and excessive loss of fluids.
Taking furosemide can cause a drop in potassium levels in your body (hypokalaemia). This drop happens because of increased removal of potassium in the urine. Though foods high in potassium are often good for health, eating an excess of these foods while on furosemide can lead to issues with potassium levels. Keep a watch on how much of the following high-potassium foods you consume.
Bananas are famed for their high potassium content. While on furosemide, have them but just in moderation.
Leafy greens like spinach and kale also have a lot of potassium. Limit the amount you eat of these vegetables and let your healthcare provider keep a check on your potassium levels.
Dried fruits such as raisins, prunes, and apricots are rich in potassium. Stick to recommended serving sizes and balance your diet with other low-potassium options.
Oranges and orange juice are high in potassium. Have them in balance and ask your doctor about how much is okay to consume.
Salmon and other fatty fish contain potassium. But, they also offer numerous health benefits, such as omega-3 fatty acids. Even so, eat salmon in balance and have a discussion about how much is right for you with your healthcare provider.
Beans, including white ones, are rich in potassium. It’s ideal to eat them in balance.
Furosemide works best when your body has the right balance of fluids. Eating huge amounts of high-fat foods can lead to weight gain and fluid retention, making it harder for furosemide to work properly. To ensure the drug works well, reduce the following high-fat foods that are mentioned below.
Fried foods like French fries, fried chicken, and doughnuts often have too much fat. They can lead to weight gain and fluid retention. Choose options that are grilled, baked, or broiled for healthier alternatives.
Choose leaner cuts of meat, such as skinless chicken breast or trimmed pork tenderloin, to reduce fat intake.
Replace high-fat dairy products like full milk, full-fat cheese, and butter with options that have less fat like skim milk, low-fat cheese, and olive oil.
Switch butter with healthier fats like olive oil, avocado, or nut butter.
Reduce sweets and desserts like pastries, cookies, and ice cream that are high in fat. When possible, choose healthier dessert options, such as fruit or yogurt.
Just like it’s key to dodge some foods when taking furosemide, it’s equally vital to eat a balanced diet to maintain your health. You may include the following food types in your daily meal plan.:
Add a mix of colourful fruits and vegetables in your diet. They offer key vitamins, minerals, and fiber and are low in salt and fat.
Choose whole grain options over refined grains, such as brown rice, whole wheat pasta, and whole grain bread. They offer more nutrients and fiber for better digestion and heart health.
Include lean protein sources, such as skinless poultry, fish, beans, and legumes, in your diet. These provide key amino acids that promote muscle growth and cellular repair without adding fat.
Choose low-fat dairy options, like skim milk, low-fat yogurt, or less-fat cheeses, to get calcium, vitamin D, and protein without the added fat.
Include healthy fats, such as avocados, nuts, seeds, and olive oil, in your diet. These fats offer key nutrients and support heart health.
Stay well-hydrated by drinking water, herbal tea, and other drinks with low calories and low salt. Proper hydration is vital when taking furosemide, as it helps maintain a healthy fluid balance in your body.
