Hypothyroidism can cause blood pressure to rise, however, since atenolol is a beta blocker, it's normally used when heart rate is too high, or a person has palpitations, since it slows the heart rate.
Additionally, 50 mg is a pretty hefty dose. At one point, I had rapid heart rate and palpitations and was put on atenolol, but it slowed my heart rate too much and I had to drop the dosage in 1/2. I also take Benazipril for HBP, along with Lasix to reduce fluid retention.
You might want to ask your doctor if there might be something that will work better for you.
A cortisol saliva test done several years ago, would not be valid, at this point. You'd have to do new adrenal tests in order to confirm that you actually have adrenal fatigue, which should usually be treated prior to treating a thyroid condition.
