In the treatment of glaucoma, Diamox helps to reduce intraocular pressure by decreasing the production of fluid inside the eye. This can help prevent damage to the optic nerve and preserve vision.

For altitude sickness prevention, Acetazolamide works by increasing the amount of bicarbonate in the blood, which leads to an increase in breathing rate. This helps to improve oxygenation and reduce symptoms associated with altitude sickness, such as headache, dizziness, and shortness of breath.

Drug may also be prescribed as an adjunctive treatment for certain types of seizures, such as absence seizures and mixed seizure patterns, although it is not considered a first-line medication for epilepsy.

Medicine is available in tablet form and is usually taken orally. The dosage and duration of treatment will vary depending on the specific condition being treated and the individual's response to the medication.

How to use

Here are general guidelines for using Diamox:

  1. Administration: Medicament is usually taken orally in tablet form. Swallow the tablet whole with a full glass of water. You may take it with or without food.
  2. Timing: Diamox is typically taken one to four times a day, depending on the condition being treated. It is important to space the doses evenly throughout the day for optimal effectiveness.
  3. Adherence: Take tablets regularly and consistently to achieve the best results. If you miss a dose, take it as soon as you remember. However, if it is close to the time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not double up on doses.
  4. Duration of treatment: The duration of Acetazolamide treatment will depend on the specific condition being treated. Do not stop taking Diamox, even if you start to feel better.
  5. Additional instructions: If Diamox is prescribed for altitude sickness prevention, it is typically started one to two days before ascending to high altitudes. Continue taking it during the ascent and for a few days after reaching the highest altitude.


The following are general guidelines for Diamox dosage:


  • For open-angle glaucoma: The typical starting dose is 250 mg to 500 mg per day, divided into two to four doses.
  • For secondary glaucoma or acute angle-closure glaucoma: The usual dosage is 250 mg to 1,000 mg per day, divided into two to four doses. Again, the dose may be adjusted based on your response to treatment.

Altitude sickness prevention:

  • The recommended dose is 125 mg to 250 mg taken twice daily, starting 24 to 48 hours before ascending to high altitudes. Continue taking Diamox during the ascent and for at least a day after reaching the highest altitude.

Seizure disorders:

  • Diamox may be used as an adjunctive treatment for certain types of seizures. The dosage will depend on various factors.

Side effects

Diamox may cause side effects in some individuals. Common side effects include:

  1. Increased urination: Acetazolamide is a diuretic, which means it increases urine production. This can lead to more frequent urination.
  2. Tingling or numbness: Some people may experience a sensation of tingling or numbness in their fingers, toes, or other parts of the body. This is usually temporary and resolves on its own.
  3. Loss of appetite: Diamox can sometimes cause a decrease in appetite, leading to reduced food intake.
  4. Nausea or stomach upset: Some individuals may experience mild gastrointestinal symptoms, such as nausea, stomach discomfort, or diarrhea.
  5. Drowsiness or fatigue: Diamox can cause drowsiness or fatigue in some people. It is important to be cautious when engaging in activities that require alertness, such as driving or operating machinery.

These side effects are usually mild and temporary.

Serious side effects are rare but can occur:

  1. Allergic reactions: Signs of an allergic reaction may include rash, itching, swelling, severe dizziness, or difficulty breathing.
  2. Blood disorders: Acetazolamide can affect blood cell production in rare cases, leading to symptoms such as easy bruising, bleeding, or signs of infection (e.g., fever, sore throat).
  3. Kidney stones: There is a potential risk of developing kidney stones with prolonged use of Diamox. Symptoms can include severe pain in the back or side, blood in the urine, or changes in urinary frequency.

This is not a comprehensive list of side effects. If you experience any other unexpected or severe side effects while taking Diamox, seek medical attention promptly.


Diamox should be stored properly to maintain its effectiveness and ensure its safety. Here are some guidelines for storing:

  1. Temperature: Store Diamox at room temperature, typically between 68°F (20°C) and 77°F (25°C). Avoid exposing it to extreme temperatures, such as freezing or excessive heat.
  2. Moisture: Keep tablets in its original tightly closed container to protect it from moisture. Moisture can affect the stability of the medication, so it is important to store it in a dry place.
  3. Light: Medicine should be protected from direct light. Keep the container away from sources of sunlight or bright artificial light.
  4. Out of reach of children and pets: Store drug in a secure location that is out of the reach of children and pets. Accidental ingestion can be harmful, so it's important to take precautions.
  5. Proper disposal: If you have any unused or expired Diamox, it is important to dispose of it properly. Follow local guidelines or consult with your pharmacist on the appropriate disposal method, such as returning it to a take-back program or using a medication disposal kit.


If you suspect an overdose of Acetazolamide or have taken more than the prescribed amount, it is important to seek immediate medical attention or contact your local poison control center. Overdosing on Diamox can be serious and may require prompt medical intervention. Here are some steps to take in case of an overdose:

  1. Call emergency services: Dial your local emergency helpline or go to the nearest emergency room immediately. Inform them about the situation and provide details of the medication, including the amount you have taken and when it was ingested.
  2. Do not induce vomiting: Vomiting may not be recommended in all cases and can potentially cause harm.
  3. Provide information: When seeking medical help, provide any relevant information about the overdose, such as the amount of Diamox taken and the time it was ingested.

It is important to remember that an overdose of Diamox can be potentially dangerous and requires immediate medical attention. Do not rely solely on online information; it is essential to seek professional medical help in such situations.

Missed Doses

If you miss a dose of Diamox, take it as soon as you remember. However, if it is close to the time for your next scheduled dose, skip the missed dose and continue with your regular dosing schedule. Do not double up on doses to make up for the missed one.

It is important to follow the prescribed dosing schedule as closely as possible to ensure the medication's effectiveness. If you frequently forget to take your doses, consider setting reminders or alarms to help you remember.
