Been taking Gemtesa for 3 weeks now. Since I started taking this medication I have noticed a drop in my pulse ox reading from 95 to 92-93 until yesterday. Yesterday my pulse ox reading was 90 and today it is still 90. Have been hospitalized when my pulse ox reading hit 88. Will quit taking the drug, as it is the only thing I have changed in three weeks. Other side effects - frequent urination with no volume (50 ml. once an hour during day). At night up 4 and 5 times a night with high volume of urine (100ml to 300ml each time).
