Enantone LP

By Medically reviewed by Hello Doktor Medical Panel


What is enantone LP (leuprolide) used for?

Leuprolide is a gonadotropin-releasing hormone (GnRH) agonist. It works by decreasing levels of certain hormones produced by the testes and ovaries. This prevents the growth of certain tumors that need these hormones to grow.

Enantone LP is commonly used for treating symptoms of advanced prostate cancer. It may also be used for other conditions as determined by your doctor.

How should I take enantone LP (leuprolide)?

Use enantone LP as directed by your doctor. Ask your health care provider any questions you may have about how to use enantone LP.

Enantone LP is usually given every month (4 weeks) as an injection at your doctor’s office, hospital, or clinic. If you will be using leuprolide at home, a health care provider will teach you how to use it. Be sure you understand how to use leuprolide. Follow the procedures you are taught when you use a dose. Contact your health care provider if you have any questions.

Do not use enantone LP if it contains particles, is cloudy or discolored, or if the vial is cracked or damaged.

Keep this product, as well as syringes and needles, out of the reach of children and away from pets. Do not reuse needles, syringes, or other materials. Ask your health care provider how to dispose of these materials after use. Follow all local rules for disposal.

How do I store enantone LP (leuprolide)?

Enantone LP is best stored at room temperature away from direct light and moisture. To prevent drug damage, you should not store enantone LP in the bathroom or the freezer. There may be different brands of enantone LP that may have different storage needs. It is important to always check the product package for instructions on storage, or ask your pharmacist. For safety, you should keep all medicines away from children and pets.

You should not flush enantone LP down the toilet or pour them into a drain unless instructed to do so. It is important to properly discard this product when it is expired or no longer needed. Consult your pharmacist for more details about how to safely discard your product.

Precautions & warnings

What should I know before using enantone LP (leuprolide)?

Before using enantone LP, tell your doctor if:

  • You are allergic to any ingredient in leuprolide, to GnRH, or to another GnRH agonist (e.g., histrelin).
  • You are pregnant, able to become pregnant, or are breastfeeding.
  • You are taking any prescription or nonprescription medicine, herbal preparation, or dietary supplement.
  • You have allergies to medicines, foods, or other substances.
  • You are taking medicines that can weaken the bones, such as anticonvulsants (e.g., phenytoin) or corticosteroids (e.g., prednisone).
  • You take any medicine that may increase the risk of a certain type of irregular heartbeat (prolonged QT interval) or seizures. Check with your doctor or pharmacist if you are unsure if any of your medicines may increase the risk of these problems.

Also, there is some important information that you may notice:

  • Certain hormone levels may increase during the first few weeks of treatment with enantone LP. This may cause you to experience worsening symptoms or onset of new symptoms (e.g., bone pain; blood in the urine; difficulty urinating; burning, numbness, or tingling) during the first few weeks of treatment. Patients with growths on or near the spine or spinal cord, or a blockage of the bladder or ureters may be at greater risk of developing serious and sometimes fatal complications. Contact your doctor if any new or worsened symptoms occur while using enantone LP.
  • Enantone LP lowers the amount of certain hormones in your body. This may cause certain expected side effects to occur, such as changes in breast size, breast soreness or tenderness, testicular changes, decreased sexual ability, hot flashes, or night sweats. Contact your doctor if you have questions or concerns or if you experience any of these side effects.
  • Enantone LP may cause your bones to weaken or become more prone to fractures, especially if you use enantone LP for long periods of time. Contact your doctor if you experience bone pain or if you have concerns regarding changes in bone density.
  • A slight increase in the risk of stroke or serious and sometimes fatal heart problems has been reported with the use of GnRH agonists in men. Although the risk appears to be low, seek immediate medical attention if you experience chest, jaw, or left arm pain; confusion; fainting; numbness of an arm or leg; one-sided weakness; slurred speech; sudden, severe headache or vomiting; or vision changes. Discuss any questions or concerns with your doctor.
  • High blood sugar and an increased risk of the development of diabetes has been reported in men who use GnRH agonists. Patients who already have diabetes may develop trouble controlling their blood sugar. High blood sugar may make you feel confused, drowsy, or thirsty. It can also make you flush, breathe faster, or have a fruit-like breath odor. If these symptoms occur, tell your doctor right away.
  • Diabetes patients: enantone LP may affect your blood sugar. Check blood sugar levels closely. Ask your doctor before you change the dose of your diabetes medicine.
  • A serious pituitary gland problem (pituitary apoplexy) has rarely been reported with the use of enantone LP. Most cases developed within 2 weeks after the first dose. Contact your doctor right away if you experience a sudden headache, vomiting, fainting, eye weakness, inability to move your eyes, mental status changes, or vision changes.
  • Leuprolide may interfere with certain lab tests, including certain hormone and pituitary gland function tests. Be sure your doctor and lab personnel know you are using leuprolide.
  • Lab tests, including blood testosterone levels, prostate-specific antigen (PSA), hemoglobin A1c, blood glucose, and bone density, may be performed while you use leuprolide. These tests may be used to monitor your condition or check for side effects. Be sure to keep all doctor and lab appointments.
  • Leuprolide should not be used in children; safety and effectiveness in children have not been confirmed.
