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.

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?

The most common side effects of JATENZO are increased red blood cell count, diarrhea, indigestion, burping, swelling of the leg or foot, nausea, enlarged prostate gland, high blood pressure, and headache.

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