How is histrelin given (Vantas)?
Histrelin is given in a tiny implant that is inserted under the skin on the inside of your upper arm. You will receive this implant with a minor surgical procedure in a clinic or doctor's office.
It is best to place the implant into your non-dominant arm (your left arm if you are right-handed). Be sure to tell your doctor which arm you use most often.
You should be lying on your back during insertion of the histrelin implant. Your arm will be positioned with your elbow bent and held still while the implant is inserted.
The skin of your upper arm will be treated with a numbing medicine to keep you from feeling pain during the insertion. Once your arm is numb, your doctor will use a scalpel to cut a small incision where the implant will be inserted.
The histrelin implant is inserted using a special tool that pushes the implant into place through the incision in your skin. After injecting the implant and removing the insertion tool, your doctor will then feel your arm to make sure the implant has been correctly placed.
The incision in your skin may be closed with a small number of stitches or surgical strips. Follow your doctor's instructions about caring for the incision and keeping it bandaged and clean until it heals completely.
After receiving your implant, keep the arm dry for at least 24 hours.
You will most likely be able to feel the implant through your skin, but it should not cause pain or discomfort. Call your doctor if you have any pain, swelling, tenderness, itching, tingling, bruising, or redness where the implant was inserted.
Call your doctor if any part of the implant comes through the skin, or if the entire implant falls out.
You may have a temporary increase in symptoms of your condition for a week or so after you have received the histrelin implant. Call your doctor if any of these symptoms become severe.
You will need regular medical tests to be sure this medication is not causing harmful effects. Visit your doctor regularly.
This medication can cause unusual results with certain medical tests. Tell any doctor who treats you that you are using histrelin.
A histrelin implant is usually left in place for 12 months and then removed. Your doctor will determine at that time whether you need to receive another implant for continued relief of prostate cancer symptoms.
Whether or not you receive a new histrelin implant, the old one must be removed after 12 months of use. A histrelin implant must be removed through a surgical incision in your doctor's office.
