My doctor prescribed another PT, urine specimin, and
complete blood count. Diagnosis was an infection in my prostate and
an INR of 10 (ten). My question: Is it possible to go from 3 to 10 in three weeks with no diet change? The only possibilty I can think of, is the addition of 50 mg per day of Atenolol for blood pressure, 3 or 4 days before this problem began. By the way, I stopped the Atenolol.
