Supprelin LA

Generic Name: histrelin (implant) (his TREL in)
Brand Names: Supprelin LA, Vantas

What is Supprelin LA?

Supprelin LA is an implant that contains histrelin, a man-made form of a hormone that regulates many processes in the body. Histrelin overstimulates the body's own production of certain hormones, which causes that production to shut down temporarily.

Supprelin LA is used to treat precocious puberty in both male and female children.

Supprelin LA may also be used for other purposes not listed in this medication guide.

Important information

You should not receive Supprelin LA if you are allergic to histrelin or other medications that affect gonadotropin hormones. Supprelin LA is used to treat precocious puberty in children. Supprelin LA can cause a miscarriage or birth defects. Do not use if you are pregnant. Use effective birth control, and tell your doctor if you become pregnant during treatment.

Before you receive Supprelin LA, tell your doctor if you have painful or difficult urination, diabetes, heart disease, coronary artery disease, liver disease, a history of heart attack or stroke, osteoporosis, or a condition affecting your spine.

You will need regular medical tests to be sure Supprelin LA is not causing harmful effects. Visit your doctor regularly.

A Supprelin LA 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 treatment of your symptoms.

How is Supprelin LA given?

Supprelin LA 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 Supprelin LA 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 Supprelin LA 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 Supprelin LA implant will be inserted.

The Supprelin LA 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 Supprelin LA 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 Supprelin LA 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 Supprelin LA implant. Call your doctor if any of these symptoms become severe.

You will need regular medical tests to be sure Supprelin LA is not causing harmful effects. Visit your doctor regularly.

Supprelin LA can cause unusual results with certain medical tests. Tell any doctor who treats you that you are using this medicine.

A Supprelin LA 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.

Whether or not you receive a new Supprelin LA implant, the old one must be removed after 12 months of use. The implant must be removed through a surgical incision in your doctor's office.

What happens if I miss a dose?

Since Supprelin LA is given as an implant by a healthcare professional, you will not be on a frequent dosing schedule.

The implant should not be left in your arm for longer than 12 months. Call your doctor when it is time for your implant to be removed.

What happens if I overdose?

Since the Supprelin LA implant contains a specific amount of the medication, you are not likely to receive an overdose.

What should I avoid?

For at least 7 days after your implant is inserted, avoid strenuous exercise or heavy lifting.
