Quick facts about VANTAS

  • The implant is different from multiple injection therapies because you get 12 months of continuous medicine with only one administration.
The VANTAS Implant
  • The implant is about an inch long and made from
    the same type of material as a contact lens.
  • VANTAS is inserted just under the skin in the upper arm during a minor surgical procedure at your doctor's office.
  • VANTAS delivers a continuous amount of drug (histrelin) each day for 12 months.
  • During the treatment year you should continue to see your doctor for monitoring of prostate specific antigen (PSA) and testosterone levels.
  • VANTAS was approved by the FDA in 2004 and has been proven to decrease testosterone in patients with prostate cancer—this reduction may help relieve the symptoms of prostate cancer. It is not a cure.
  • As with any medication, you should inform your doctor if you have any side effects when taking VANTAS. The most common side effects of VANTAS in clinical trials were: hot flashes, tiredness, skin reactions at the implant insertion site, testicles may become smaller, urination problems, breasts may become larger, erectile dysfunction (impotence), and constipation.
  • Ask your doctor if VANTAS is right for you.
