It is very important that your doctor check the progress of you or your child at regular visits to make sure the implant is in the proper place and is working properly. Blood tests may be needed to check for unwanted effects.

For female patients: You should not receive this medicine if you are pregnant or may become pregnant. Using this medicine while you are pregnant can harm your unborn baby. Use an effective form of birth control to keep from getting pregnant during treatment with this medicine. If you think you have become pregnant while using the medicine, tell your doctor right away.

You may have some pain, redness, or bruising at the site where the implant is placed. If your arm has not healed within 2 weeks after you received the implant or if you continue to have redness or pain, call your doctor.

For children using Supprelin® LA:

  • The medicine can cause a brief increase in blood levels of some hormones. During this time, you may notice more signs of puberty in your child, including light vaginal bleeding and breast enlargement in girls. If your child's symptoms do not improve within 4 weeks, or if they get worse, call your doctor.
  • This medicine may cause some children to be agitated, irritable, or display other abnormal behaviors. Make sure the doctor knows if your child is having trouble sleeping, gets upset easily, has a big increase in energy, or starts to act reckless. Also tell the doctor if your child has sudden or strong feelings, such as feeling nervous, angry, restless, violent, or scared. If you or your caregiver notice any of these side effects, tell your doctor right away.
  • Using this medicine may increase your child's risk of having seizures. Check with your doctor right away if your child starts to have convulsions, muscle spasm or jerking of all extremities, sudden loss of consciousness, or loss of bladder control.

For male patients:

  • When you start using Vantas®, some of your symptoms might get worse for a short time. You might also have new symptoms such as bone pain, back pain, a tingling or numbness in the body, blood in the urine, or trouble urinating. The symptoms should improve in a few weeks. Tell your doctor if you have any new symptoms or your symptoms get worse.
  • This medicine may cause your blood sugar level to increase. If you are diabetic and notice a change in the results of your blood or urine sugar tests, check with your doctor.
  • This medicine may increase your risk of having a heart attack or stroke. Check with your doctor right away if you have chest pain or discomfort, difficulty with speaking, headache, pain or discomfort in the arms, jaw, back or neck, shortness of breath, sweating, or vomiting while using the medicine.
  • Contact your doctor right away if you have any changes to your heart rhythm. You might feel dizzy or faint, or you might have a fast, pounding, or uneven heartbeat. Make sure your doctor knows if you or anyone in your family has ever had a heart rhythm problem such as QT prolongation.

Before you have any medical tests, tell the medical doctor in charge that you are using histrelin implant. The results of some tests may be affected by this medicine.
