FDA approval of furosemide
Furosemide has been approved by the U.S. Food and Drug Administration (FDA) for the treatment of edema (fluid retention) associated with congestive heart failure, liver disease, or kidney disease, as well as for the treatment of hypertension (high blood pressure).
Is furosemide available in the UK on NHS?
Yes, furosemide is available in the UK with a National Health Service (NHS) prescription.
Mechanism of action
Furosemide belongs to a class of medications called loop diuretics. It works by blocking the reabsorption of sodium and chloride in the kidneys, leading to increased urine production and a decrease in fluid retention. This helps to reduce swelling and lower blood pressure.
Uses of furosemide
Furosemide is a medication that is commonly used to treat various conditions related to fluid retention and high blood pressure (hypertension). It belongs to a class of drugs called diuretics, which work by increasing the amount of urine produced by the kidneys. Here are some specific uses of furosemide:
- Furosemide is often prescribed to alleviate edema, which is the excessive accumulation of fluid in the body tissues. It is commonly used to treat edema associated with conditions like congestive heart failure, liver cirrhosis, kidney disease, and certain lung conditions
- Furosemide is also used to manage high blood pressure, either alone or in combination with other antihypertensive medications. By increasing urine production, it helps to reduce the fluid volume in the blood vessels, thus lowering blood pressure
- Furosemide is frequently prescribed to patients with kidney disease to help manage fluid overload and control blood pressure. It can be particularly beneficial for individuals with conditions like nephrotic syndrome or acute kidney injury
- Furosemide is sometimes used as an adjunct treatment for hypercalcemia, a condition characterized by abnormally high calcium levels in the blood. It helps to promote calcium excretion through urine, thereby reducing blood calcium levels
- In some cases, furosemide may be prescribed off-label to manage certain conditions like pulmonary edema, ascites (fluid buildup in the abdomen), and certain types of glaucoma
Dosage of furosemide
The dosage of furosemide may vary depending on the specific condition being treated, individual patient factors, and the healthcare provider’s assessment. It is important to follow the dosage instructions provided by your healthcare provider. Furosemide is available in tablet form with various strengths (e.g., 20 mg, 40 mg, 80 mg). The appropriate dosage will be determined by your healthcare provider based on your specific needs. If you miss a dose of furosemide, it is important to take the missed dose as soon as you remember. However, if it is close to the time for your next dose, skip the missed dose and continue with your regular dosing schedule. Do not take a double dose to make up for the missed one.
Forms of furosemide
Furosemide is available in tablet form for oral administration. The tablets come in various strengths. Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light.
Is it safe to take furosemide if I am pregnant or planning on becoming pregnant?
It is important to consult your healthcare provider if you are pregnant or planning to become pregnant before taking furosemide. The use of furosemide during pregnancy should be carefully considered, as it may pose risks to the unborn baby. Your healthcare provider can provide guidance based on your individual situation.
Is furosemide safe to use while breastfeeding?
Furosemide may pass into breast milk, and its use during breastfeeding should be discussed with your healthcare provider. The potential risks and benefits for both the mother and the baby should be evaluated, and a decision should be made based on the specific circumstances.
Precautions and warnings for furosemide
- Always speak with your healthcare professional about possible interactions with all prescription drugs, vitamins, herbs and supplements, and over-the-counter drugs that you are taking
- Furosemide could make you sunburn more easily. Avoid sunlight or tanning beds. Wear protective clothing and use sunscreen (SPF 30 or higher) when you are outdoors
- Using more than your recommended dose will not make this medicine more effective. High doses of furosemide may cause irreversible hearing loss
Here are some possible interactions to consider:
- NSAIDs (nonsteroidal anti-inflammatory drugs) such as ibuprofen or naproxen, may reduce the diuretic effect of furosemide. This interaction can decrease the effectiveness of furosemide in treating conditions like edema or hypertension
- Furosemide can increase the excretion of lithium in the urine, potentially reducing its effectiveness in treating bipolar disorder. Close monitoring of lithium levels and adjusting the dosage may be necessary if these medications are taken together
- Concurrent use of furosemide with corticosteroids, such as prednisone, can increase the risk of low potassium levels or hypokalemia. Regular monitoring of potassium levels may be needed when these medications are used together
- Furosemide can cause electrolyte imbalances, particularly low potassium levels, which can increase the toxicity of digoxin, a medication used for heart failure. It is crucial to monitor potassium levels and adjust the dosage of digoxin if necessary when taking furosemide
- Furosemide can enhance the blood pressure-lowering effect of ACE inhibitors or ARBs (angiotensin receptor blockers) potentially causing a significant drop in blood pressure. Close monitoring of blood pressure is important when these medications are used together
- Concurrent use of furosemide with aminoglycoside antibiotics, such as gentamicin or amikacin, can increase the risk of kidney problems. Close monitoring of kidney function and adjusting the dosages may be necessary when these medications are taken together
- Combining furosemide with other diuretics, such as hydrochlorothiazide or spironolactone, can increase the risk of dehydration and electrolyte imbalances. Close monitoring of fluid status and electrolyte levels is important when using these medications together
It is essential to inform your healthcare provider about all the medications you are taking, including prescription medications, over-the-counter drugs, and herbal supplements. They can assess the potential interactions and adjust the dosages or recommend alternative medicines if needed.
Side effects of furosemide
The most common side effects and adverse effects of taking furosemide include:
- Furosemide is a diuretic, meaning it increases urine production. This can lead to more frequent urination
- The increased urination caused by furosemide can sometimes result in dehydration. Symptoms include increased thirst, dry mouth, feeling faint or lightheaded, headache, and dark yellow or brown urine. It is important to stay adequately hydrated while taking this medication
- Furosemide can cause electrolyte imbalances in the body, such as potassium, sodium and magnesium. This can lead to symptoms like increased thirst or urination, constipation, muscle weakness, leg cramps, numbness or tingling, feeling jittery and fluttering in your chest
- Furosemide can cause a drop in blood pressure (hypotension), resulting in dizziness, lightheadedness, drowsiness or fainting. It is important to get up slowly from a sitting or lying position to minimize these effects
- Furosemide can cause changes in blood sugar levels
- Some individuals may experience dizziness or blurred vision while taking furosemide. If these symptoms occur, it is advisable to seek medical attention as they may indicate a more serious reaction
- Although rare, some individuals may have an allergic reaction to furosemide. Signs of an allergic reaction may include rash, itching, swelling, severe dizziness, or trouble breathing. If any of these symptoms occur, it is important to seek immediate medical attention
- Furosemide can increase the levels of uric acid in the body, which can trigger gout attacks in individuals who are prone to this condition. If you have a history of gout, it is important to discuss this with your healthcare provider before starting furosemide
It is important to note that this is not an exhaustive list of side effects, and other serious side effects may occur. It is always recommended to read the medication leaflet and consult with a healthcare professional if you have concerns about the side effects of furosemide.
