Diamox vs Lasix
Introduction
For patients dealing with edema or glaucoma, certain drugs that facilitate the elimination of excess fluids in the body can help manage these conditions. Diamox and Lasix are two such diuretics often prescribed for these purposes. Both medications aid in reducing fluid accumulation but they work on different parts of the kidneys - the organ primarily responsible for managing fluid balance in humans.
Diamox, known as Acetazolamide, is a carbonic anhydrase inhibitor that promotes diuresis by affecting bicarbonate (HCO3-) reabsorption in the kidney's proximal tubules. It is also used off-label for altitude sickness prevention.
On the other hand, Lasix or Furosemide belongs to a class of drugs called loop diuretics and acts on a different part of kidney – Loop of Henle - where it inhibits sodium (Na+), potassium (K+), and chloride (Cl-) reabsorption leading to increased urine output. Both have their unique side effects profile which needs careful consideration before prescribing them.

What is Diamox?
Acetazolamide (the generic name for Diamox) was the first drug of its kind, a carbonic anhydrase inhibitor. It marked a significant advancement from traditional diuretics and received FDA approval in 1953. Diamox works by reducing the activity of a protein in your body called carbonic anhydrase, leading to reduced fluid retention and decreased intraocular pressure - it's often prescribed for glaucoma treatment or high-altitude sickness prevention. On the other hand, Furosemide (Lasix), another diuretic approved by the FDA later in 1982, inhibits sodium reabsorption in the kidney – this leads to increased urine production which helps expel extra fluid from your body. Lasix is frequently used to treat swelling and fluid build-up due to heart failure or liver disease. While both drugs serve as effective diuretics with different mechanisms of action, Lasix can interact with more medications than Diamox due to its potent effect on electrolyte balance.
What conditions is Diamox approved to treat?
Diamox is approved for the management of various medical conditions, including:
- Glaucoma: It helps to decrease intraocular pressure
- Acute mountain sickness (AMS): It aids in preventing and reducing the symptoms of altitude sickness
- Edema due to congestive heart failure: When other medications are inadequate
- Certain epileptic seizures: Particularly absence seizures when other treatments have failed or are not suitable
How does Diamox help with these illnesses?
Diamox, or acetazolamide, is a medication often used to manage conditions associated with elevated intraocular pressure like glaucoma or acute mountain sickness. It works by inhibiting an enzyme called carbonic anhydrase in the kidneys, leading to increased excretion of bicarbonate. This causes a decrease in fluid movement into the eyes and brain due to changes in electrolyte concentrations, thereby reducing intraocular and intracranial pressures.
On the other hand, Lasix (furosemide) primarily targets excess fluid accumulation in the body such as that seen in heart failure or liver disease. It acts on a specific protein located within kidney cells known as Na-K-2Cl symporter which ultimately leads to increased urine production — this process helps reduce swelling and lowers blood pressure.
The choice between Diamox and Lasix depends largely on the patient’s condition: Diamox may be better suited for patients dealing with eye diseases or altitude sickness while Lasix is typically chosen for individuals struggling with edema from heart failure or liver disease.
What is Lasix?
Lasix is a brand name for furosemide, which is a loop diuretic. This means that it functions by inhibiting the reabsorption of sodium and chloride in the kidney's ascending Loop of Henle, thus leading to an increase in urine output (diuresis). Furosemide was first approved by the FDA in 1966. As Lasix isn't a carbonic anhydrase inhibitor like Diamox (acetazolamide), it doesn’t work on reducing fluid accumulation within specific parts of the body such as eyes or brain achieved by reducing production of aqueous humor and cerebrospinal fluid respectively, which are common applications for Diamox. Its primary action lies in its potent diuretic effect useful against conditions like edema related to heart failure, liver disease or kidney disease; and hypertension. The effects on sodium and water excretion can be beneficial for managing these conditions especially when patients do not respond well to “typical” forms of treatment.
What conditions is Lasix approved to treat?
Lasix, also known as furosemide, is approved for the treatment of:
- Edema (fluid retention) due to heart failure or kidney disease
- Hypertension (high blood pressure), which can prevent strokes, heart attacks and kidney problems.
This medication works by prompting your body to get rid of extra salt and water. Lasix is a strong diuretic commonly referred to as a "water pill."
How does Lasix help with these illnesses?
Lasix, also known as furosemide, is a loop diuretic that works by inhibiting the reabsorption of sodium and chloride in the kidneys. This process increases urine output and helps reduce fluid buildup in patients with conditions such as heart failure, liver disease, or kidney disease. Lasix's role in reducing fluid retention can significantly alleviate symptoms such as shortness of breath and swelling (edema). It does this more effectively than Diamox which primarily reduces fluid production within the eye to treat glaucoma rather than systemic edema. Its action on renal tubules may also play roles in its effectiveness as a diuretic. Since it has a stronger diuretic effect compared to carbonic anhydrase inhibitors like Diamox, Lasix is often prescribed when there is a need for rapid or high-volume diuresis.
How effective are both Diamox and Lasix?
Both acetazolamide (Diamox) and furosemide (Lasix) have been long used for their diuretic effects, having received FDA approval in the 1950s. They work on different parts of the kidney to increase urine output but are prescribed under distinct circumstances due to their unique pharmacological profiles.
The efficacy of acetazolamide and furosemide as diuretics was directly compared in a double-blind clinical trial in 1975; both drugs showed similar efficacy in increasing urinary output, but with distinctive electrolyte excretion patterns. In this study, none of the metrics studied — including volume of urine produced or changes in blood pressure — revealed significant differences between patients receiving Diamox and those receiving Lasix. A more recent clinical trial conducted in 2016 noted that while Lasix is generally more potent as a diuretic, Diamox has less likelihood to cause hypokalemia (low potassium levels).
A review carried out in 2008 concluded that Diamox is effective at reducing intraocular pressure starting from the first day of treatment, making it an important drug for managing glaucoma symptoms. The side effect profile is generally favorable when compared to other carbonic anhydrase inhibitors, and it's well-tolerated even among elderly populations.
Furosemide remains one of the most commonly prescribed loop diuretics worldwide due to its pronounced natriuresis - sodium excretion through urine - effect which aids fluid elimination from body tissues. Significant research on its use involves treating edema associated with heart failure or liver cirrhosis where rapid onset diuresis is required. Nonetheless, despite being very effective at removing excess fluid from the body’s tissues quickly – within one hour after oral administration – chronic use can lead to electrolyte imbalances such as hyponatremia(low sodium level), hypokalemia(low potassium level), and hypocalcemia(low calcium level). Hence regular monitoring of serum electrolytes becomes necessary during prolonged treatment with Lasix.

At what dose is Diamox typically prescribed?
Oral dosages of Diamox typically range from 250–1000 mg/day, and it has been found that a daily dosage of 500 mg is often adequate for managing symptoms associated with altitude sickness. Children's dosages should be decided by a healthcare provider, usually starting at the lower end of this range. If no response or inadequate response to treatment is observed, the dosage may be increased after consulting with a medical professional. However, in all cases, it's important not to exceed the maximum recommended dose of 1000 mg/day without specific direction from your healthcare provider.
At what dose is Lasix typically prescribed?
Lasix therapy typically begins at a dosage of 20-80 mg/day. This dose can then be increased to up to 600 mg/day, divided into multiple doses spaced throughout the day. The maximum dose is highly dependent on the individual's response and tolerance to treatment, but high doses should only be used in severe conditions. If there is no sufficient response to the initial Lasix dosage after a few days, your doctor may incrementally increase your daily amount or divide it into separate doses taken throughout the day until an effective level is reached.
What are the most common side effects for Diamox?
Some of the common side effects of Diamox and Lasix include:
- Frequent urination
- Dizziness, lightheadedness or fainting spells
- Nausea, vomiting or decreased appetite

- Hearing problems (e.g., ringing in your ears), sudden hearing loss
- Liver disease: nausea/vomiting that doesn't stop, loss of appetite/belly pain on the upper right side/jaundice (yellowing of the eyes/skin)
- Kidney issues like painful/difficult urination/changes in quantity/frequency/color/smell/clarity/cloudiness/unusual weight gain It's essential to stay vigilant for these signs and consult with a healthcare professional if they arise.
Contraindications for Diamox and Lasix?
Just like Prozac and Wellbutrin, both Diamox (acetazolamide) and Lasix (furosemide), which are diuretics or "water pills", may cause your existing health conditions to deteriorate in some instances. If you notice worsening symptoms such as confusion, increased thirst, swelling hands/ankles/feet or unusual fatigue while taking these medications, seek immediate medical attention.
Neither Diamox nor Lasix should be taken if you have been using certain other types of drugs including digoxin or lithium. Always inform your healthcare provider about all the current medications that you are on; these include prescription/non-prescription drugs as well as herbal products since they might require a period for clearance from your system to prevent dangerous interactions with Diamox and Lasix.
Also remember that while on either medication, it's important to monitor blood sugar levels regularly if diabetic due to possible alterations caused by drug interaction. Furthermore, avoid becoming overly thirsty since excessive water intake can alter the balance of electrolytes leading potentially severe complications.
How much do Diamox and Lasix cost?
For the brand name versions of these drugs:
- The price for 30 tablets of Diamox (125 mg) averages around $140, which works out to about $4.67 per day.
- The price for 30 tablets of Lasix (40 mg) averages around $16, working out to approximately $0.53/day.
Thus, if you are in a higher dosage range for Diamox (i.e., 250 mg/day or higher), then the brand-name Lasix is less expensive on a per-day treatment basis. Please note that cost should not be a primary consideration in determining which of these drugs is right for you.
For generic versions of both medications:
- Acetazolamide (generic Diamox) costs roughly between $0.35 and $1.10 per tablet depending on strength and quantity purchased, with dosages typically ranging from one half up to four full tablets taken each day.
- Furosemide (generic Lasix), available in packs starting as low as 15 tablets all the way up to hundreds at once, may start from just over two cents ($0.02+) per tablet when purchased in larger quantities and go up based on strength and volume bought; typical daily doses usually consist of one or two tablets only.
Remember that prices can vary significantly by area and pharmacy so it's always worth checking multiple locations before making any purchases if possible!
Popularity of Diamox and Lasix
Acetazolamide, commonly known by the brand name Diamox, is a medication used primarily to treat glaucoma, seizures related to epilepsy, and altitude sickness. Despite its specialized uses, it was still prescribed to approximately 1.6 million people in the United States in 2020.
Furosemide, popularly referred to by the brand name Lasix, had significantly more prescriptions written for it during that same year at about 32.8 million. Furosemide is primarily utilized as a diuretic for patients with congestive heart failure and edema related to liver disease or kidney disease.
The prevalence of furosemide has remained steady over time due largely attributed to its effectiveness and affordable cost compared with other diuretics on the market. Acetazolamide's usage has also been relatively stable over time despite its niche applications.
Conclusion
Both Diamox (acetazolamide) and Lasix (furosemide) have been used for many years in managing various conditions, particularly those related to fluid accumulation. They are both diuretics but work on different parts of the kidney due to their distinct mechanisms of action. Diamox is a carbonic anhydrase inhibitor that primarily affects the proximal convoluted tubule, making it useful in treating glaucoma and altitude sickness as well as edema. On the other hand, Lasix is a loop diuretic that works predominantly on the ascending limb of the Loop of Henle; it's commonly used in heart failure patients or those with severe edema.
While both drugs can be combined under certain circumstances like refractory edema, this should only occur under careful medical supervision due to potential complications including electrolyte imbalances.
Both Diamox and Lasix are available in generic form which may represent substantial cost savings for patients who pay out-of-pocket. Both medications might need dose adjustments during therapy based on patient response.
The side effect profile is somewhat similar between these two drugs - they're generally well-tolerated but side effects can include dehydration symptoms such as dry mouth or thirst, increased urination frequency and electrolyte disturbances among others. For either drug, if unusual symptoms arise such as rapid weight loss or gain or severe dizziness upon standing up - immediate medical attention should be sought.
