What is the altitude or height of the retreat and surroundings does we need any medication for altitude sickness?

The altitude of Kathmandu from sea level is around 1400 meter, Bhaktapur is around 1350 meter, Telkot place of resort varies between 2000 meter while Nagarkot the sunrise point is at 2175 meters from the sea level, so these are the mostly visited places during the course, if you feel any altitude sickness then you can carry some medicine along with you but it is very normal height for any new person as well.
