Acetazolamide (Eytazox)

Acetazolamide is a mild diuretic usually given to correct abnormal fluid retention and to treat Glaucoma. Recent studies have found that it is safe and effective in reducing the risk of altitude sickness and associated symptoms. It has a notable effect on acclimatisation allowing a better and more tolerable climbing experience.

Overview of Eytazox

Eytazox contains Acetazolamide which is a carbonic anhydrase inhibitor. It acts in the kidney to increase the excretion of Bicarbonate, sodium and potassium in the urine. This helps to decrease the alkalosis which occurs during ascent especially after 3000 m. It also increases the acidity of the blood enabling the body to maintain and possibly increase its oxygen intake at higher altitudes, thus augmenting the body's capability of acclimatisation.

How to take Eytazox

The usual dosage of Eytazox is 125- 250 mg administered once or twice a day. The Tablets should be taken one to two days before entering an altitude of 1500 m, and taken every day as directed until the desired altitude level is reached. Once the descent occurs, the tablets can be stopped.

The Prescribing Doctor will confirm the most appropriate dosage for you. If you are uncertain, our Doctors are available to provide one-to-one expert advice and recommendations.

Staying safe with Prescription Doctor

As with all medications, there are certain risks when taking Eytazox if you have any medical conditions or taking medications detailed below:-

If any of the following apply to you, inform our doctors to ensure Eytazox is safe for you.

  • Diabetic
  • Suffer from blood clots
  • Taking lithium preparations
  • Medications which interfere with folic acid such as methotrexate
  • Sodium bicarbonate preparations.

Please inform our doctor of any medication or conditions to ensure Eytazox is safe and effective for you.

Eytazox should not be taken with Aspirin or Aspirin containing products, such as Anadin, as it can cause toxic reactions.

Do not take if you are pregnant or breastfeeding.

Adverse effects when using Eytazox

Eytazox is relatively safe and effective. Its side effects are usually mild and lessen the longer it is taken. However, it is important to understand the potential effects that can occur. We recommend reading the Patient Information Leaflet to familiarise yourself with this medication.

Ordering your Eytazox online

Our doctors recommend conducting thorough research before travelling and climbing to high altitudes. Prophylactic treatment with Eytazox can be obtained after a consultation with our doctor. If approved before 3 pm, the UK registered pharmacy can dispatch your order for a next day delivery. The medical team recommend obtaining your supply well in advance of your trip as the course of treatment should be started a few days before.
