At over 3,000m above sea-level it isn’t possible to take in as much oxygen which makes breathing difficult and between 6 and 24 hours after reaching that height, altitude symptoms may develop. Acetazolamide is an altitude medication which effectively treats and prevents the symptoms of elevation sickness, such as: shortness of breath, loss of appetite, tiredness, dizziness, nausea and vomiting and headache. By taking Acetazolamide medicine 1-2 days before the trip and whilst going up in altitude, these symptoms should be minimal.

  • Altitude Sickness

    Altitude sickness can occur when you travel to a high altitude too quickly.

    Breathing becomes difficult because you aren’t able to take in as much oxygen.

    Altitude sickness, also called acute mountain sickness (AMS), can become a medical emergency if ignored.

    Age, sex or physical fitness have no bearing on your likelihood of getting altitude sickness.

    Just because you haven’t had it before doesn’t mean you won’t develop it on another trip.

    <h3>Symptoms of altitude sickness</h3>
    Symptoms of altitude sickness usually develop between 6 and 24 hours after reaching altitudes more than 3,000m (9,842 feet) above sea level.

    Symptoms are similar to those of a bad hangover.

    They include:

    nausea and vomiting
    loss of appetite
    shortness of breath
    The symptoms are usually worse at night.


    Consider travelling with these medicines for altitude sickness:

    acetazolamide to prevent and treat high altitude sickness
    ibuprofen and paracetamol for headaches
    anti-sickness medication, like promethazine, for nausea

    Preventing altitude sickness
    The best way to prevent altitude sickness is to travel to altitudes above 3,000m slowly.

    It usually takes a few days for the body to get used to a change in altitude.

    You should also:

    avoid flying directly to areas of high altitude, if possible
    take 2-3 days to get used to high altitudes before going above 3,000m
    avoid climbing more than 300-500m a day
    have a rest day every 600-900m you go up, or every 3-4 days
    make sure you’re drinking enough water
    avoid alcohol
    avoid strenuous exercise for the first 24 hours
    eat a light but high calorie diet
    avoid smoking
    Acetazolamide, available from a travel clinic and, in some areas, your GP, can help prevent symptoms. It’s thought to help you adjust more quickly to high altitudes.

    You should begin taking the medication 1-2 days before you start to go up in altitude and continue to take it while going up.

    If using acetazolamide, you should still go up gradually and follow the general prevention advice.

    If you get symptoms of altitude sickness while taking acetazolamide, you should rest or go down until you feel better before going up again.

    After 2-3 days, your body should have adjusted to the altitude and your symptoms should disappear.

    See a doctor if your symptoms don’t improve or get worse.

    If the symptoms of altitude sickness are ignored, they can lead to life-threatening conditions affecting the brain or lungs.

    High altitude cerebral oedema (HACE)
    High altitude cerebral oedema (HACE) is the swelling of the brain caused by a lack of oxygen.

    Symptoms of HACE:

    nausea and vomiting
    loss of co-ordination
    feeling confused
    A person with HACE often doesn’t realise they’re ill, and may insist they’re all right and want to be left alone.

    HACE can develop quickly over a few hours. It can be fatal if it’s not treated immediately.

    Treating HACE:

    move down to a lower altitude immediately
    take dexamethasone
    give bottled oxygen, if available
    Dexamethasone is a steroid medication that reduces swelling of the brain.

    If you can’t go down immediately, dexamethasone can help relieve symptoms until it’s safe to do so.

    You should go to hospital as soon as possible for follow-up treatment.

    High altitude pulmonary oedema (HAPE)
    High altitude pulmonary oedema (HAPE) is a build-up of fluid in the lungs.

    Symptoms of HAPE:

    blue tinge to the skin (cyanosis)
    breathing difficulties, even when resting
    tightness in the chest
    a persistent cough, bringing up pink or white frothy liquid (sputum)
    tiredness and weakness
    The symptoms of HAPE can start to appear a few days after arrival at high altitude. It can be fatal if it’s not treated immediately.

    Treating HAPE:

    move down to a lower altitude immediately
    take nifedipine
    give bottled oxygen, if available
    The medication nifedipine helps to reduce chest tightness and ease breathing.

    You should go to hospital as soon as possible for follow-up treatment.

    If you’ve had HAPE, you can register with the International HAPE Database to help develop new treatments for the condition.
