question: Hello doctor, I am a 71-year-old male with h/o HTN and diabetes. They are well under control with Amlopres one tablet daily and Cetaphin 500 mg two tablets daily, Clopitab 75 mg one tablet daily. I have a cyst in my kidney which is asymptotic. Nephrologist did not prescribe any medicine for that. My general health is good and I walk about 4 km daily. I am planning a week-long vacation to a place which is 10000 feet altitude high. I had been to places that are higher than that height, but I did not stay there for not more than a day. In order to acclimatize to high altitude, I plan to take Lopar SR 250 mg twice a day for three days. Will this help me to stay at 10000 feet for about five days? Are these tablets contra indicated for me? I seek your valued advice in this regard. My wife has COPD, but under control with Seriflo 250 mg rotacaps daily.
