Altitude sickness happens when your body struggles to adjust to lower oxygen levels at high elevations. High altitude is generally considered to be 2,500 metres above sea level, and symptoms can include headache, nausea, dizziness, shortness of breath and fatigue.

Acetazolamide is commonly used to help prevent altitude sickness. It helps the body adjust to high altitude and can reduce symptoms such as headaches and nausea when used correctly as part of a prevention plan.

This service is suitable for adults aged 18 and over, subject to a clinical consultation with the pharmacist to check that the medication is appropriate and safe for you.

The source service lists Acetazolamide 250mg tablets at £20 for 10 tablets. Pricing at Thame Pharmacy should be confirmed when booking or during your consultation.

The source guidance states a dose of half a 250mg tablet, which is 125mg, twice daily starting one day before ascent and continuing for two days once acclimatised or once descent begins. Always follow the advice given by the pharmacist.

Yes. Altitude sickness tablets are prescription-only in the UK, so a pharmacist consultation is required before medication can be supplied.

Gradual ascent, allowing time to acclimatise, staying hydrated, avoiding alcohol and taking it easy during the first few days at altitude can all help reduce the risk of altitude sickness.

If you develop symptoms, you should stop ascending, rest and stay hydrated. If symptoms persist or become severe, descend to a lower altitude and seek urgent medical advice.

You can book an appointment online or contact Thame Pharmacy directly for advice before travelling. The pharmacist will assess your suitability and explain how to use the medication safely.
