Question

What can affect your prostate-specific antigen levels?

Answer 1

• Your prostate-specific antigen (PSA) level can also be affected by other factors: Age. Your PSA will normally go up slowly as you age, even if you have no prostate problems.
• Medications. Some drugs may affect blood PSA levels. Tell your health care provider if you are taking finasteride (Proscar or Propecia) or dutasteride (Avodart). These drugs may falsely lower PSA levels typically by half of what it would normally be.
