Lupron Depot



Generic Name: Leuprolide
Other Trade Names: Eligard TM, Lupron ®, Viadur TM

Drug Type:

Lupron Depot is a hormone therapy.  Lupron Depot  is classified as an "LHRH agonist." For more detail, see "How Lupron Depot Works" section below).

What Lupron Depot Is Used For:

  • Prostate cancer
  • Breast, ovarian and endometrial cancer
  • Also used in non-cancerous conditions such as endometriosis, infertility, benign prostatic hypertrophy (BPH).

Note:  If a drug has been approved for one use, physicians may elect to use this same drug for other problems if they believe it may be helpful.

How Lupron Depot Is Given:

  • As an injection under the skin (subcutaneous, SubQ), or into the muscle (intramuscular, IM).
  • May be given as a daily, monthly, or every 3 or 4month injection depending on the formulation and condition being treated.
  • Also may be given as a once-a-year implantable device (Viadur(tm)).  The device looks like a one and 1/2 inch coffee stirrer.  It is implanted under the skin.  Positioned at one end of the device are "osmotic tablets."  These tablets expand in the presence of water drawn in from the surrounding tissue at a constant and steady rate. As water is drawn in through this end, it exerts pressure inside the implant that steadily pushes the right amount of medication out of a small hole in the other end.  The device is removed at the end of the year.
  • There is no pill form of Lupron Depot.
  • Your doctor will determine your dose and schedule.

Lupron Depot Side Effects:

  • Lupron Depot side effects are almost always reversible and will go away after treatment is complete.
  • There are many options to help minimize or prevent Lupron Depot side effects.
  • There is no relationship between the presence or severity of Lupron Depot side effects and the effectiveness of Lupron Depot.

The following Lupron Depot side effects are common (occurring in greater than 30%) for patients taking Lupron Depot:

These Lupron Depot side effects are less common side effects (occurring in about 10-29%) of patients receiving Lupron Depot:

  • Increased bone pain or urinary retention due to disease "flare" during first couple weeks of treatment.
  • Breast pain (see sexuality)
  • Discomfort at injection site
  • Blood test abnormalities - increased cholesterol levels
  • Swelling of feet or ankles (edema)
  • Weakness -general loss of strength
  • Swelling of the breasts (gynecomastia) (see sexuality)
  • Depression
  • Sweating

Lupron Depot may cause short-term (within first 2 weeks of treatment) increases in testosterone serum levels.  When this is used for prostate cancer the resulting "tumor flare" can cause temporary increase of bone pain, swelling of the prostate that blocks urine flow or swelling around tumor in the spine causing compression of the spinal cord.  If you are noticing increased weakness, numbness or tingling in arms or legs, or difficulty with urination, report these symptoms to your health care provider immediately.

Rare but significant side effects may include heart problems such as congestive heart failure (1%) or problems with blood clots (1%).  Blood clots can lead to pulmonary embolus or stroke - potentially life-threatening conditions. 

Not all Lupron Depot side effects are listed above. Some that are rare (occurring in less than 10% of patients) are not listed here.  However, you should always inform your health care provider if you experience any unusual symptoms.

Monitoring and Testing While Taking Lupron Depot:

You will be checked regularly by your health care professional while you are taking Lupron Depot, to monitor side effects and check your response to therapy.  Periodic blood work to monitor your complete blood count (CBC) as well as the function of other organs (such as your kidneys and liver) may also be ordered by your doctor.   

How Lupron Depot Works:

Hormones are chemical substances that are produced by glands in the body, which enter the bloodstream and cause effects in other tissues.  For example, the hormone testosterone, made in the testicles and is responsible for male characteristics such as deepening voice and increased body hair.  The use of hormone therapy to treat cancer is based on the observation that receptors for specific hormones that are needed for cell growth are on the surface of some tumor cells.  Hormone therapy can work by stopping the production of a certain hormone, blocking hormone receptors, or substituting chemically similar agents for the active hormone, which cannot be used by the tumor cell. Different types of hormone therapies are categorized by their function and/or the type of hormone that is affected.

Lupron Depot is classified as a leutinizing hormone releasing hormone (LHRH) agonist. HRH agonists work by telling the pituitary gland located in the brain to stop producing leutinizing hormone, which (in men) stimulates the testicles to release testosterone and (in women) stimulates the ovaries to release estrogen.  Lupron Depot does not have a direct effect on the cancer, only on the testicles or ovaries.   The resulting lack of testosterone (in men) and estrogen (in women) interferes with stimulating cell growth in testosterone or estrogen dependent cancer cells.

In treatment of prostate cancer LHRH agonists are often used together with anti-androgen medications. Anti-androgens are substances that block the effects of testosterone. Cancer of the prostate depends on the male hormone testosterone for its growth.  If the amount of testosterone is reduced it is possible to slow down or shrink the cancer.

  • Examples of anti-androgens are: bicalutamide, flutamide, nilutamide.
