• Malaria (optional)
  Please note that Malaria prevention is not necessarily recommended for your trip to Tanzania. Especially for climbing Kilimanjaro you will spend most of your time at higher altitude where Malaria is not present. You should also consider that Malaria prevention can cause side-effects and that it is no 100% guarantee to prevent Malaria infections. We only recommend it for safaris at the Southern Safari Circuit. Please talk to your health care provider about further details.

• Medicine for Altitude Mountain Sickness (optional)
  Please note that it is not recommended nor promoted to use AMS prevention medicine. In fact, thousands of hikers manage to summit Kilimanjaro without those preventatives. AMS preventatives can cause side-effects such as nausea, stomach problems and fatigue which can lower your successful climb so please consider consulting your doctor before using such medicines.

• Pain killers to treat light headache and muscle pain (optional)
  Sooner or later most hikers will experience some slight headache on the mountain due to the lack of oxygen. We are constantly monitoring the blood oxygen levels of our hikers but carrying some pain killers is recommended to be prepared for some light headache that might occur.
