Altitude Sickness Treatment

Advice for Travellers from Woodstock Road Chemist

Reaching a mountain summit, trekking through the Andes or flying into a high-altitude city can be an unforgettable experience. A rapid increase in elevation, however, may leave the body without enough time to adjust to reduced oxygen levels.

Woodstock Road Chemist provides personalised high-altitude travel advice and access to altitude sickness tablets in Oxford for eligible travellers. Our healthcare professional will review your route, ascent profile, previous experiences at altitude, medical history and current medicines before deciding whether preventive medication is appropriate.

Why Does Altitude Sickness Develop?

Altitude sickness can occur when someone travels to a high elevation too quickly. It is generally a concern above 2,500 metres, although individual responses vary. Physical fitness does not prevent it, and even an experienced, healthy traveller can become unwell.

Risk is influenced by how high you sleep, how rapidly you ascend and whether your body has time to acclimatise. Flying directly to places such as La Paz or travelling quickly into the Himalayas, Andes or East African mountains can create a different risk from reaching the same elevation gradually.

Previous altitude sickness increases the likelihood of experiencing it again, but completing an earlier trip without symptoms does not guarantee protection.

Recognising Acute Mountain Sickness

Mild altitude illness is often called acute mountain sickness, or AMS. Symptoms commonly begin within several hours of arriving at a higher elevation and may include:

• -> Headache
• -> Nausea, vomiting or loss of appetite
• -> Dizziness or feeling light-headed
• -> Unusual tiredness or weakness
• -> Difficulty sleeping

These symptoms should not be ignored or dismissed as dehydration, a hangover or ordinary fatigue. Do not continue climbing or move to a higher sleeping altitude while symptoms remain. Rest at the same elevation and tell a travelling companion or guide that you feel unwell.

Warning Signs That Require Immediate Action

Altitude illness can progress to swelling affecting the brain or fluid in the lungs. These conditions are medical emergencies. Warning signs can include:

• -> Confusion, unusual behaviour or extreme drowsiness
• -> Difficulty walking in a straight line or poor coordination
• -> Breathlessness while resting
• -> A persistent cough or frothy or blood-stained sputum
• -> Blue or grey lips, skin or nails
• -> Symptoms that are becoming worse despite resting

If severe symptoms develop at high altitude, obtain urgent medical help immediately and do not travel any higher. If you are on a mountain or overland route and it is safe to descend, move around 300 to 1,000 metres lower with another person where possible. Travellers in a high-altitude city or resort who cannot descend safely should contact the local emergency services, as oxygen or medical evacuation may be required.

Plan a Gradual Ascent

Allowing time to acclimatise is the most important preventive measure. Once above 3,000 metres, avoid increasing your sleeping altitude too quickly and include regular rest days. Your exact plan should reflect the terrain, available accommodation and the advice of an experienced operator.

To support acclimatisation:

• -> Spend a few days below 2,500 metres before travelling higher where possible
• -> Avoid going directly from below 1,200 metres to above 3,500 metres in one day
• -> Keep increases in sleeping altitude modest once above 3,000 metres
• -> Include a rest day at the same elevation every three to four days
• -> Drink enough water to avoid dehydration
• -> Avoid alcohol during your ascent
• -> Build flexibility into the itinerary so you are not pressured to continue climbing when unwell

Ascending higher during the day and returning to a lower elevation to sleep may support acclimatisation. However, no itinerary removes the risk completely, and symptoms should guide your decisions.

Can Altitude Sickness Tablets Help?

Altitude sickness tablets containing acetazolamide may help prevent symptoms by helping the body adjust to high altitude more quickly. They may be considered when rapid ascent is unavoidable or for travellers with a relevant history of altitude illness. However, they do not guarantee protection and cannot compensate for an unsafe ascent plan.

Acetazolamide is used off-label for altitude-illness prevention in the UK. If it is clinically appropriate, our team will discuss the possible benefits and side effects and provide instructions for taking it.

Suitability depends on factors including allergies, kidney or liver conditions, pregnancy, breastfeeding and other medicines. Tingling in the fingers or toes, changes in taste, increased urination, dizziness or stomach upset can occur. Travellers should try the medicine before reaching a remote high-altitude location if advised to do so.

Prepare for Your Consultation

If you can, bring a rough day-by-day itinerary as well as elevations of your overnight stops, if appropriate. During your appointment, we will consider:

• -> The elevation at each overnight stop
• -> How quickly you will move between sleeping altitudes
• -> Planned trekking, climbing or other physical activity
• -> Access to guides, oxygen, evacuation and medical facilities
• -> Previous altitude exposure, symptoms and treatment
• -> Medical conditions, allergies and current medication

Through our travel health service in Oxford, your assessment can also cover vaccinations, malaria prevention and other precautions connected with your route.
