What Is Altitude Sickness?

Altitude sickness, also known as high altitude illness, can happen when you travel to places over 2,500 metres above sea level. At higher altitudes, oxygen levels drop, and your body may struggle to adjust, especially if you ascend too quickly.
It’s commonly experienced in destinations such as the Alps, Mount Kilimanjaro, La Paz, or trekking routes. While symptoms are often mild and improve with rest, altitude sickness can occasionally become serious if not managed early.

Altitude Sickness Symptoms to Watch For

Symptoms usually start 6–10 hours after reaching a high altitude and may include:
  • Headache
  • Loss of appetite
  • Feeling sick or vomiting
  • Extreme tiredness
  • Dizziness or light-headedness
  • Difficulty sleeping
Mild symptoms are common and often settle with rest. However, if symptoms worsen or do not improve, it’s important to act quickly to avoid complications.

What to Expect

What Causes Altitude Sickness?

  • Altitude sickness is most likely when:
  • You travel to high altitude too quickly.
  • You don’t give your body time to acclimatise.
  • You’ve had altitude sickness before.
  • You become dehydrated or drink alcohol.
  • Understanding these triggers is key to altitude sickness prevention and safer travel planning.

Altitude Sickness Treatment & Relief

Most cases improve with rest at the same altitude. However, our expert pharmacists can advise on altitude sickness treatment, including:
  • Pain relief such as paracetamol or ibuprofen.
  • Anti-sickness medication.
  • Preventive medication for those at higher risk.
  • Guidance on when to descend or seek urgent medical care.
In more severe cases, oxygen therapy or hospital treatment may be required, and we will clearly advise you when to seek urgent medical care or escalation.

How to Prevent Altitude Sickness

Simple steps can greatly reduce your risk:
  • Ascend slowly and allow time to adjust.
  • Take rest days during climbs.
  • Drink plenty of water.
  • Avoid alcohol.
  • Avoid sleeping much higher than the previous night.
  • Speak to a pharmacist before travel if you’ve had altitude sickness before.
Prevention is most effective when advice is taken before you travel, not once symptoms have started. Our team can provide guidance on altitude sickness prevention strategies tailored to your trip.
