Eligard is administered by a healthcare provider as an injection. Here are the general steps involved in the process:
- Preparation: The injection is usually prepared in a medical office or clinic. The healthcare provider will mix the medication from a powder form into a solution.
- Administration: The injection is given subcutaneously (under the skin), usually in the abdomen or upper thigh. The needle is typically small, and the injection is quick.
- Regular Monitoring: You will typically need regular appointments for your doctor to monitor the effectiveness of the treatment and to check for side effects.
Missed Dose: If you miss a scheduled dose, it is important to contact your doctor immediately. The injection schedule is essential for maintaining consistent testosterone suppression, so your doctor may need to adjust the timing or dose of your next injection.
Eligard contains leuprolide acetate, which works by interfering with the normal hormonal signals that regulate testosterone production. Here’s how it functions:
- Gonadotropin-Releasing Hormone (GnRH) Agonist: Leuprolide acetate is a synthetic form of GnRH, a hormone that is normally produced in the brain. When it is injected, it initially causes a temporary increase in testosterone levels, but over time, continuous use leads to a significant decrease in testosterone production.
- Testosterone Suppression: After a few weeks of treatment, the body adjusts to the ongoing presence of leuprolide acetate and reduces the secretion of luteinizing hormone (LH) and follicle-stimulating hormone (FSH), which are responsible for stimulating the testes to produce testosterone. This results in a decrease in testosterone levels to very low levels, which can stop or slow the growth of prostate cancer cells that require testosterone to grow.
Cancer Control: By lowering testosterone levels, Eligard helps in the management of advanced prostate cancer, especially in patients with metastatic prostate cancer or in combination with other treatments like radiation therapy or surgery.
While Eligard is generally well-tolerated, there are potential side effects. Common side effects may include:
- Hot Flashes: One of the most common side effects of Eligard is the occurrence of hot flashes, which may feel like sudden warmth or sweating.
- Sexual Dysfunction: Reduced libido (sexual desire) and erectile dysfunction (difficulty getting or maintaining an erection) are common due to the suppression of testosterone.
- Injection Site Reactions: Some people may experience redness, pain, or swelling at the site of the injection.
- Fatigue: Many patients report feeling unusually tired or fatigued during treatment.
- Mood Changes: Emotional changes such as irritability, depression, or anxiety can occur due to the hormonal changes caused by the treatment.
Bone Density Loss: Long-term use of Eligard can lead to a decrease in bone mineral density, increasing the risk of osteoporosis or bone fractures.
- Medications affecting hormone levels: Other medications that influence hormonal balance, such as anti-androgens or estrogen-based therapies, may interact with Eligard. Combining these therapies can sometimes alter the effectiveness of treatment.
- Other cancer treatments: If you are undergoing chemotherapy or other forms of hormone therapy, your doctor will carefully monitor your regimen to avoid possible interactions.
- Blood thinners: Eligard does not have a direct interaction with blood thinners, but your healthcare provider will monitor your condition if you’re taking such medications due to potential side effects from cancer treatment.
Always inform your doctor about all the medications and supplements you are currently taking to prevent harmful interactions.
Eligard is typically administered by your doctor in the following doses:
- 7.5 mg every month
- 22.5 mg every 3 months
- 30 mg every 4 months
The exact dosage and schedule will depend on the stage of your prostate cancer, response to the treatment, and your doctor’s recommendation. It’s important to follow your doctor’s guidance for the most effective and safe treatment plan.
Eligard is a prescription-only medication, meaning it must be prescribed by a healthcare provider. It is administered by a doctor or healthcare professional in a medical setting as an injection. Before starting treatment with Eligard, your doctor will assess your overall health and prostate cancer stage to determine if it is the appropriate treatment for you.
Regular monitoring and follow-up appointments are necessary to adjust the treatment as needed and to manage any potential side effects.
