If your doctor has directed you to use this medication, remember that he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects. Tell your doctor right away if this unlikely but serious side effect occurs: rectal bleeding. A very serious allergic reaction to this drug is unlikely, but seek immediate medical attention if it occurs.
Since the air pressure is lower at high altitudes, your body may struggle to absorb much-needed oxygen. This can cause disorientation, headaches, nausea, shortness of breath and weakness. In severe cases people have been hospitalized. There are many ways to get used to the altitude so you can still enjoy your getaway.
Temperature increases as you gain altitude in the stratosphere and the thermosphere. Temperature decreases as you gain altitude in the troposphere and mesosphere. Air temperature varies in complicated ways with altitude. Near the Earth's surface, air gets cooler the higher you climb. As you climb a mountain, you can expect the air temperature to decrease by 6.5 degrees C for every 1000 meters you gain. This is called the standard (average) lapse rate. If air temperature is 30 degrees C at sea level as shown above, you can expect it to be around 10.5 degrees C at air altitude of 3000 meters because of the lapse rate. Plan an expedition! You are going to climb Mount Audubon in Colorado today!
