Why is this medication prescribed?

Vantas is prescribed for the treatment of advanced prostate cancer. Prostate cancer is a type of cancer that develops in the prostate, a small gland that produces seminal fluid in men. In some cases, prostate cancer cells are dependent on the male hormone testosterone for their growth.

Vantas contains histrelin acetate, which is a synthetic form of gonadotropin-releasing hormone (GnRH). GnRH agonists like histrelin work by initially increasing the levels of testosterone in the body, leading to what is known as an “initial flare.” However, this increase is temporary, and over time, the continuous exposure to GnRH agonists suppresses the production of testosterone. The reduction in testosterone levels can slow down the growth of prostate cancer cells.

Vantas is often used when other treatment options for advanced prostate cancer are not suitable or have not been effective. It is administered as a subcutaneous implant, releasing histrelin over an extended period to maintain a consistent therapeutic effect.

How should this medicine be used?

Vantas (histrelin acetate) is typically administered as a subcutaneous implant for the treatment of advanced prostate cancer. The implant is inserted under the skin, usually in the upper arm, and it releases a controlled amount of histrelin over an extended period. The specific instructions for using Vantas may vary, so it’s essential to follow the advice and guidance provided by the prescribing healthcare professional. Here are general guidelines for the use of Vantas:

• Administration: Vantas is administered by a healthcare professional in a medical setting. The subcutaneous implant is placed under the skin during a minor surgical procedure.
• Dosage: The dosage and duration of treatment with Vantas will be determined by the healthcare provider based on the individual patient’s condition. The implant provides a sustained release of histrelin over a specified period.
• Monitoring: Regular follow-up appointments with the healthcare provider are important to monitor the response to treatment and assess any potential side effects. Testosterone levels may be monitored to ensure the desired therapeutic effect.
• Duration of Treatment: Treatment with Vantas is typically long-term, and the implant may need to be replaced periodically, depending on the specific product used. The healthcare provider will determine the appropriate duration of treatment based on the patient’s condition.
• Side Effects: Patients should be aware of potential side effects and report any unusual or severe symptoms to their healthcare provider promptly.
• Patient Education: Patients receiving Vantas should be educated about the medication, its purpose, and the importance of adhering to the prescribed treatment plan. They should also be aware of any potential side effects and when to seek medical attention.
