t53 pill

Acetazolamide decreases the activity of a protein found in the body known as carbonic anhydrase. The blockage of this protein may help to reduce the accumulation of specific fluids within the body.

Acetazolamide can be used by those with specific types of Glaucoma to lower amounts of fluid inside the eye, thereby reducing pressure in the eye.

Acetazolamide can also be used as a diuretic (“water pill”) for people suffering from constricted heart disease in order to limit the amount of fluid that builds up in the body. This accumulation is known as edema.

Warning and precautions

It is not recommended to use acetazolamide in the case of cirrhosis or kidney or liver disease, an imbalance in electrolytes or adrenal gland failure as well as an allergic reaction to acetazolamide, or sulfa medications.


  • The dose increase does not cause diuresis to increase and can increase the likelihood of paresthesia or drowsiness. In most cases, increasing the dose causes an increase in diuresis. However, in certain instances, high doses of diuretics are administered in conjunction with diuretics to maintain diuresis an irreparable failure.

Information for Patients

  • Common adverse reactions to all sulfonamide derivatives can result in fever, anaphylaxis, and anaphylaxis. rash (including Steven-Johnson syndrome neurotoxic epidermal necrosis) and crystalluria. They can also cause renal calculus bone marrow depression hemolytic anemia, thrombocytopenic purpura pancytopenia, leukopenia, and Agranulocytosis. It is recommended to be cautious for the early detection of reactions, and the medication should be stopped and appropriate treatment implemented.
  • In patients suffering from emphysema or pulmonary obstruction where breathing through the alveoli is compromised, extended-release capsules of acetazolamide that may cause or aggravate acidosis should be utilized with cautiousness. A gradual ascent is recommended in order to avoid the onset of mountain sickness.


  •  In the event that rapid climbing is attempted and acetazolamide extended-release capsules are employed, it is observed that this method doesn’t eliminate the necessity of a rapid descent in the event that severe forms of high altitude illness occur, i.e., high altitude pulmonary edema (HAPE) as well as high altitude cerebral swelling.
  • A cautious approach is advised for those taking concomitant high-dose aspirin and acetazolamide extended-release capsules, since anorexia, lethargy, tachypnea, metabolic acidosis, coma, as well as deaths have been documented.


  • Both decreases and increases in blood glucose levels have been reported in patients by Acetazolamide. This is something to take into account in patients suffering from an impaired tolerance to glucose or with diabetes.
  • Acetazolamide treatment could result in electrolyte imbalances, such as hypokalemia and hyponatremia, and metabolic acidosis. Therefore, regular surveillance of electrolytes in the serum is advised. Particular caution is advised for patients suffering from conditions related to or may cause acid/base imbalances and electrolytes like those with impaired kidney function and patients suffering from diabetes mellitus, or with impaired alveolar venting.
  • A few adverse reactions associated with Acetazolamide, including fatigue, drowsiness, and myopia, could hinder the ability to operate and drive machines.

Laboratory Tests

  • To detect Hematologic reactions that are common to all sulfonamides it is suggested to conduct an initial CBC as well as a platelet count is taken on patients prior to starting extended-release acetazolamide capsules and every few weeks during treatment. If there are significant changes the prompt discontinuation and implementation of the correct therapy is essential. Regular monitoring of electrolytes in serum is suggested.
