Prevent Altitude Sickness with Acetazolamide (Diamox) UK

Travelling to high-altitude destinations like the Himalayas, Andes, or Kilimanjaro is exciting, but it comes with a common risk: altitude sickness. This condition, also known as acute mountain sickness (AMS), occurs when the body struggles to adjust to reduced oxygen levels at elevations above 2,500 metres. The good news is that altitude sickness can often be prevented and managed with Acetazolamide (Diamox), a trusted prescription medication available in the UK through travel clinics such as VitalMeds.

In this guide, we’ll explore what altitude sickness is, how acetazolamide works, recommended dosages, possible side effects, and how you can get this medicine in the UK before your trip.

What is Altitude Sickness?

Altitude sickness happens when your body cannot adapt quickly to the lower oxygen levels at higher altitudes. It can affect travellers of any age, gender, or fitness level.

Common symptoms of altitude sickness include:

• Headache
  
• Nausea and vomiting
  
• Dizziness
  
• Shortness of breath
  
• Fatigue
  
• Difficulty sleeping
  

In severe cases, altitude sickness can lead to life-threatening complications such as high-altitude pulmonary oedema (HAPE) or high-altitude cerebral oedema (HACE). This is why prevention is essential for anyone planning high-altitude travel.

Why Prevention is Important

Many travellers assume they can simply ‘push through’ altitude sickness, but this can be dangerous. Preventing symptoms with the right medication, hydration, and gradual ascent is far safer than waiting for the illness to develop.

One of the most widely recommended preventive medicines is Acetazolamide (brand name: Diamox). It not only reduces the risk of altitude sickness but also helps speed up acclimatisation.

Acetazolamide (Diamox)

Acetazolamide is a carbonic anhydrase inhibitor that works by helping the body adjust to lower oxygen levels. It does this by slightly acidifying the blood, which stimulates deeper and faster breathing. This increases oxygen intake, reducing the symptoms of altitude sickness.

Key benefits of Acetazolamide for altitude sickness:

• Reduces risk of acute mountain sickness
  
• Speeds up acclimatisation
  
• Eases headache, nausea, and fatigue
  
• Allows travellers to continue their journey safely

Acetazolamide Dosage for Altitude Sickness

The recommended dosage may vary depending on your doctor’s advice, but general guidance is:

• Prevention: 125 mg to 250 mg twice daily, starting 1–2 days before ascent and continuing for at least 2 days at altitude or until you are fully acclimatised.
  
• Treatment: 250 mg twice daily until symptoms improve.
  

It is important to follow your doctor’s instructions carefully and not to exceed the prescribed dose.

When to start taking Acetazolamide:

• Ideally, begin 24–48 hours before your ascent.
  
• Continue while climbing and for a few days at high altitude.
  

Side Effects of Acetazolamide (Diamox)

Like all medicines, Acetazolamide can cause side effects, though most are usually mild and short-lived. The body generally adjusts to the medication within a few days, but it’s important to be aware of what you might experience. Knowing these possible reactions helps travellers prepare better and avoid unnecessary worry during their trip.

Common side effects include:

• Tingling in fingers or toes
• Increased urination
• Altered taste (especially with carbonated drinks)
• Nausea or upset stomach

Rare but serious side effects may include:

• Allergic reactions (rash, swelling, difficulty breathing)
• Severe fatigue
• Vision changes

If you experience severe or worrying symptoms, seek medical advice immediately.

Who Should Not Take Acetazolamide?

Acetazolamide is safe and effective for most travellers, but it may not be suitable for everyone. People with certain health conditions or sensitivities should avoid taking this medicine unless prescribed by a doctor. Discussing your medical history with a travel clinic before your trip ensures you are taking the safest option possible.

You should inform your doctor if you:

• Have kidney or liver problems
• Are allergic to sulfa medicines
• Are pregnant or breastfeeding
• Have electrolyte imbalances

Always consult your doctor or travel clinic before starting any medication.

Other Ways to Prevent Altitude Sickness

While Acetazolamide is highly effective, prevention also depends on good travel habits:

• Ascend gradually – Avoid climbing more than 300–500 metres per day once above 2,500 metres.
  
• Stay hydrated – Drink plenty of water but avoid excessive alcohol.
  
• Eat light meals – High-carbohydrate foods can help.
  
• Rest properly – Don’t overexert yourself.
  
• Consider rest days – Schedule acclimatisation days at certain altitudes.
  

These lifestyle measures combined with Acetazolamide offer the best protection against altitude sickness.
