What is JATENZO?

JATENZO® (testosterone undecanoate) capsules are prescribed to adult men for testosterone replacement therapy when they have a deficiency or absence of their natural testosterone due to structural or genetic causes.

Safety and efficacy of JATENZO in boys less than 18 years old have not been established. JATENZO is a controlled substance, CIII, due to risk for physical and psychological dependence and abuse.

What important safety information is there for JATENZO?

  • JATENZO might raise your blood pressure, which could cause serious heart problems like heart attacks, strokes, or even death related to heart conditions.
  • Before taking JATENZO, your doctor should check your blood pressure and consider your risk for heart problems. Your doctor should also periodically monitor new-onset and pre-existing high blood pressure.
  • Due to this risk, JATENZO should only be used for treatment of men who have a deficiency or absence of natural testosterone due to structural or genetic causes.

Who should not take JATENZO?

JATENZO should not be used in men with breast cancer or known or suspected prostate cancer, in women who are pregnant, in men who are 
over-sensitive to JATENZO or its ingredients, or in men with low testosterone that is not associated with structural or genetic factors.

What side effects should I be aware of before starting JATENZO?

Enlarged or painful breasts.

Changes in mood. Talk to your healthcare provider if you have changes in mood or behavior including, new or worsening depression, or suicidal thoughts.

What are the most common side effects with JATENZO?

What medications should I tell my doctor that I am taking before starting JATENZO?
