A Dr. Mehmet Oz, MD , Cardiology (Cardiovascular Disease), answered. There are blood pressure medications that do not cause erectile dysfunction (ED). Some older blood pressure medications, especially beta blockers and thiazide diuretics, are the most likely to cause ED as a side effect. Better options include calcium channel blockers, which lower high blood pressure through a different mechanism.
Causes of secondary high blood pressure include: 1  Kidney disease, such as narrowing of the kidney arteries. 2  Certain medicines, such as birth control pills, amphetamines, appetite suppressants, some antidepressants, steroids, and some nonsteroidal anti-inflammatory drugs (NSAIDs).f a health problem is the cause, this high blood pressure may return to normal when the other health problem is treated. But treating the condition that has caused your secondary high blood pressure will not always lower blood pressure back to a normal level.
