The Common Side Effects of Once-Yearly VANTAS®

VANTAS® can cause an increase in testosterone during the first week after it is inserted. Your symptoms may get worse for a few weeks. You may get new symptoms. Call your doctor right away if you:

  • Get new or worse bone pain
  • Get weakness or lose feeling in your legs
  • Have blood in your urine
  • Have trouble urinating or cannot urinate

VANTAS® can cause a loss in bone mineral density. Low bone mineral density can lead to thinning of the bones (osteoporosis).

The most common side effects of VANTAS®

  • Hot flashes
  • Tiredness
  • Skin reactions at the implant insertion site
  • Testicles become smaller
  • Urination problems
  • Breasts may become larger
  • Erectile dysfunction (impotence)
  • Constipation

You may have some pain at the insertion site during and after VANTAS® is inserted and removed. You may get some bruising and redness at the site. These usually go away without treatment within 2 weeks. Call your doctor if you have unusual bleeding, redness, or pain at the insertion site.

These are not all the side effects of VANTAS®. Please see additional Important Safety Information below. For more information, ask your doctor or pharmacist.

VANTAS® can be expelled from your body through the original incision site. This occurs infrequently. You may actually notice the implant being expelled or, rarely, the implant may be expelled without your noticing it. If you believe VANTAS® has been expelled from your body, call your doctor. Also, remember to see your doctor for routine checks on your condition to ensure that VANTAS® is present and functioning in your body.
