Casodex is an anti-androgen. It works in the body by preventing the actions of androgens (male hormones).

Casodex is used to treat prostate cancer that has spread to other parts of the body (metastatic).

Casodex is given in combination with another medicine called a luteinizing (LOO-tee-in-ize-ing) hormone-releasing hormone, or LHRH. LHRH helps prevent the testicles from producing testosterone.

Warnings

Casodex is used to treat prostate cancer. This medicine should never be taken by a woman or a child.

Bicalutamide can harm an unborn baby if you father a child while using this medicine. Use effective birth control to prevent pregnancy while using Casodex and for at least 130 days (about 19 weeks) after your last dose.

Casodex can harm your liver. Call your doctor at once if you have nausea, upper stomach pain, itching, loss of appetite, dark urine, clay-colored stools, or jaundice (yellowing of the skin or eyes).

Before taking this medicine

You should not use Casodex if you are allergic to bicalutamide.

Use effective birth control if your sex partner is able to get pregnant. Bicalutamide can harm an unborn baby if you father a child while using this medicine. Keep using birth control for at least 130 days (about 19 weeks) after your last dose.

Casodex is not for use by women or children.

This medicine can cause birth defects if a woman takes it during pregnancy.

To make sure Casodex is safe for you, tell your doctor if you have:

  • liver disease; or
  • diabetes.

How should I take Casodex?

Take Casodex exactly as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets. Your doctor may occasionally change your dose.

Casodex is usually taken once per day in the morning or evening.

Dosage form: subcutaneous implant (50 mg)
Drug classes: Gonadotropin releasing hormones  , Hormones / antineoplastics 

What is histrelin?

Histrelin overstimulates the body’s own production of certain hormones, which causes that production to shut down temporarily.

The Supprelin LA brand of histrelin is used to treat precocious puberty in both male and female children who are at least 2 years old.

The Vantas brand of histrelin is used to treat symptoms of prostate cancer in men. Vantas treats only the symptoms of prostate cancer but does not treat the cancer itself.

Histrelin may also be used for purposes not listed in this medication guide.

Histrelin side effects

Get emergency medical help if you have signs of an allergic reaction: hives; difficult breathing; swelling of your face, lips, tongue, or throat.

Histrelin may cause serious side effects. Call your doctor at once if you have:

  • bone pain, numbness or weakness in your legs or feet;
  • painful or difficult urination, blood in your urine;
  • a seizure;
  • increased pressure inside the skull–severe headaches, ringing in your ears, dizziness, nausea, vision problems, pain behind your eyes; or

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA .

Warnings

Histrelin can harm an unborn baby or cause a miscarriage. Do not use if you are pregnant.

Histrelin can cause side effects such as crying spells, anger, aggression, and feeling restless or irritable. Call your doctor if you have any new or worsening mental problems.

Before taking this medicine

You should not be treated with histrelin if you are allergic to histrelin or to similar hormone medications such as leuprolide, nafarelin, ganirelix, Eligard, Lupron, Viadur, and others.

Do not use histrelin if you are pregnant. It could harm the unborn baby or cause a miscarriage. Use effective birth control to prevent pregnancy and tell your doctor right away if you become pregnant.

Vantas should not be used in women or children.

To make sure Supprelin LA is safe for you, tell your doctor if you have ever had:

  • mental illness or psychosis;
  • epilepsy or other seizure disorder;
  • a tumor or blood vessel disorder in your brain; or
  • if you take a medicine that can cause seizures (such as an antidepressant).

To make sure Vantas is safe for you, tell your doctor if you have ever had:

  • a bladder obstruction or other urination problems;
  • diabetes;
  • heart problems, heart attack, or stroke;
  • long QT syndrome (in you or a family member);
  • low bone mineral density (osteoporosis); or
  • a condition affecting your spine.

It may not be safe to breastfeed while using this medicine. Ask your doctor about any risk.

Supprelin LA should not be used in a child younger than 2 years old. Vantas is not approved for use by anyone younger than 18 years old.

How is histrelin given?

Histrelin is given in a tiny implant 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 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.

The skin of your upper arm will be treated with a numbing medicine to keep you from feeling pain during the insertion. Your doctor will use a scalpel to cut a small incision where the implant will be inserted.

The histrelin 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 stitches or surgical strips. Follow your doctor’s instructions about caring for the incision and keeping it bandaged and clean until it heals completely. Keep your arm dry for at least 24 hours.

You will most likely be able to feel the 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, or if the implant comes through the skin or falls out.

A histrelin implant is usually left in place for 12 months and then must be removed through a surgical incision. Do not try to remove the implant yourself. Your doctor will determine whether you need another implant for continued treatment.

You may have a temporary increase in precocious puberty symptoms for a week or so after you have received the Supprelin LA implant.

You may need medical tests to help your doctor determine how long to treat you with histrelin.

Histrelin can cause unusual results with certain medical tests. Tell any doctor who treats you that you are using histrelin.

Drug classes: Gonadotropin releasing hormones Hormones / antineoplastics 

What is leuprolide?

Leuprolide injection (Eligard, Lupron Depot) is used to treat the symptoms associated with advanced prostate cancer.

Leuprolide injection (Lupron Depot-PED, Fensolvi) is used in children 2 years of age or older to treat central precocious puberty (CPP; a condition causing girls [usually younger than 8 years of age] and boys [usually younger than 9 years of age] to enter puberty too soon, resulting in faster than normal bone growth and development of sexual characteristics).

Leuprolide injection (Lupron Depot) is used alone or with another medication (norethindrone) to treat endometriosis (a condition in which the type of tissue that lines the uterus [womb] grows in other areas of the body and causes pain, heavy or irregular menstruation [periods], and other symptoms).

Leuprolide injection (Lupron Depot) is also used with other medication to treat anemia (a lower than normal number of red blood cells) caused by uterine fibroids (noncancerous growths in the uterus).

Leuprolide belongs to a class of medications called gonadotropin-releasing hormone (GnRH) agonists. It works by decreasing the amount of certain hormones in the body.

Leuprolide side effects

Get emergency medical help if you have signs of an allergic reaction to leuprolide (hives, difficult breathing, swelling in your face or throat) or a severe skin reaction (fever, sore throat, burning eyes, skin pain, red or purple skin rash with blistering and peeling).

Call your doctor at once if you have a seizure, unusual changes in mood or behavior (crying spells, irritability, restlessness, anger, aggression), severe headaches, ringing in your ears, dizziness, nausea, vision problems, or pain behind your eyes.

Your symptoms may become temporarily worse when you first start using leuprolide, including new or worsening symptoms of sexual development in children. Tell your doctor if this continues for longer than 2 months.

Leuprolide may cause serious side effects. Call your doctor at once if you have:

  • bone pain, loss of movement in any part of your body;
  • swelling, rapid weight gain;
  • a seizure;
  • unusual changes in mood or behavior (crying spells, anger, feeling irritable);
  • sudden chest pain or discomfort, wheezing, dry cough or hack;
  • painful or difficult urination;
  • pain or unusual sensations in your back, numbness, weakness, or tingly feeling in your legs or feet;
  • muscle weakness or loss of muscle use, loss of bladder or bowel control;
  • problems with your pituitary gland – sudden severe headache, vomiting, problems with your eyes or vision, changes in mood or behavior;
  • high blood sugar – increased thirst, increased urination, hunger, dry mouth, fruity breath odor;
  • heart attack symptoms – chest pain or pressure, pain spreading to your jaw or shoulder, nausea, sweating; or
  • signs of a stroke – sudden numbness or weakness, severe headache, slurred speech, problems with vision or balance.

Common leuprolide side effects may include:

  • pituitary gland problems;
  • acne, itching, rash, white scales (seborrhea);
  • cold symptoms such as stuffy nose, sneezing, sore throat, cough with or without mucus;

Leuprolide can affect growth in children. Tell your doctor if your child is not growing at a normal rate while using leuprolide.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to FDA .

Warnings

Your symptoms may become temporarily worse when you first start using leuprolide, including new or worsening symptoms of sexual development in children. Tell your doctor if this continues for longer than 2 months.

Call your doctor at once if you have a seizure, unusual changes in mood or behavior, severe headaches, ringing in your ears, dizziness, nausea, vision problems, or pain behind your eyes.

Do not use leuprolide if you are pregnant. Use effective birth control. Do not use if you have abnormal vaginal bleeding that has not been checked by a doctor.

Before taking this medicine

You should not use this medicine if you are allergic to leuprolide or similar medicines such as buserelin, goserelin, histrelin, nafarelin, or if you have abnormal vaginal bleeding that has not been checked by a doctor.

To make sure leuprolide is safe for you, tell your doctor if you have ever had:

  • depression, mental illness, or psychosis;
  • seizures or epilepsy;
  • a blood vessel disorder;
  • a brain tumor or spinal cord injury;
  • heart disease, congestive heart failure, long QT syndrome;
  • an electrolyte imbalance (such as low levels of potassium or magnesium in your blood); or
  • risk factors for bone loss (personal or family history of osteoporosis, smoking, alcohol use, taking steroid or seizure medicines long term).

Leuprolide usually causes women to stop ovulating or having menstrual periods. However, you may still be able to get pregnant. Use barrier birth control to prevent pregnancy: condom, diaphragm, cervical cap, or contraceptive sponge.

Call your doctor if your periods continue while you are being treated with leuprolide.

Leuprolide may cause birth defects. Do not use leuprolide if you are pregnant. Tell your doctor if you become pregnant.

Ask a doctor if it is safe to breastfeed while using this medicine.

How should I use leuprolide?

Uae leuprolide as prescribed by your doctor. Follow all directions on your prescription label and read all medication guides or instruction sheets.

There are many brands, strengths, or forms of leuprolide used to treat different conditions. Avoid medication errors by using only the medicine your doctor prescribes.

Leuprolide is usually administered by a healthcare provider.

Leuprolide is injected under the skin or into a muscle, once every month or once every 3 to 6 months. A healthcare provider may teach you how to properly use the medication by yourself.

Your symptoms may become temporarily worse as your hormones adjust to leuprolide. A child using this medicine may have increased signs of puberty (such as vaginal bleeding) during the first weeks of treatment.

You may need frequent medical tests while using leuprolide.

Do not reuse a needle or syringe. Place them in a puncture-proof “sharps” container and dispose of it following state or local laws. Keep out of the reach of children and pets.

Follow all storage instructions provided with leuprolide. Your pharmacist can provide more information about how to store this medicine.

What is Lupron Depot?

Lupron Depot is a long-acting, prescription hormonal injection used to treat various hormone-related conditions, such as advanced prostate cancer, endometriosis, uterine fibroids, and central precocious puberty (CPP) in children (Lupron Depot-Ped only).

  • Lupron Depot and Lupron Depot-Ped are given by injection every 1, 3, 4, or 6 months depending on the condition.
  • Lupron Depot-Ped is only for CPP. 
  • “Depot” refers to the delivery system. The medication is suspended in microspheres that slowly break down over 1-6 months.

Lupron Depot (leuprolide acetate) first gained FDA approval on April 9, 1985. There is no generic.

FDA approvals and indications

Lupron Depot is approved for advanced prostate cancer, endometriosis, and uterine fibroids.

Advanced prostate cancer

The treatment of advanced prostate cancer.

Endometriosis

The management of endometriosis, including pain relief and reduction of endometriotic lesions.

  • May be used alone or in combination with norethindrone acetate (add-back therapy) to reduce bone loss and hot flashes associated with Lupron depot use. 
  • The total duration of treatment should not exceed 12 months.

Uterine Fibroids

To improve anemia due to vaginal bleeding from uterine fibroids (uterine leiomyomata) in combination with iron therapy in patients in whom 3 months of hormonal suppression is deemed necessary.

  • The duration of treatment is limited to 3 months.
  • The symptoms associated with fibroids will return after stopping therapy.

Healthcare providers may consider a 1-month trial of iron alone, as some women will respond to iron alone.

  • Lupron Depot may be added if the response to iron alone is inadequate.

Serious side effects and warnings

Your symptoms may become temporarily worse during the first 2 to 4 weeks of treatment when you first start using Lupron Depot. In adults with prostate cancer, increases in serum testosterone of more than 50% above baseline may cause a tumor flare. Tell your healthcare provider immediately if you develop increased bone pain, nerve pain, blood in your urine, difficulty urinating, or spinal pain.

In adults or children prescribed Lupron Depot for other conditions this may cause transient worsening of symptoms, including the signs and symptoms of endometriosis or uterine fibroids during the first few weeks of treatment. In children, there may be a temporary increase in the clinical signs and symptoms of puberty, including vaginal bleeding. Tell your doctor if any increase in symptoms continues for longer than 2 months.

Cardiovascular disease. There is an increased risk of serious cardiovascular problems, including heart attacks, sudden cardiac death, and strokes in men receiving Lupron Depot. Your doctor will monitor your heart health more closely while you’re on this medication. Tell your healthcare provider immediately if you experience chest pain or pressure, shortness of breath, or sudden weakness or numbness, especially on one side of the body.

May be associated with an increased risk of seizures. The risk of seizures may be higher in people who have a history of seizures, have a history of epilepsy, have a history of brain or brain vessel (cerebrovascular) problems or tumors, are taking a medicine that has been connected to seizures such as bupropion or selective serotonin reuptake inhibitors (SSRIs). Seizures have also happened in people without any of these problems. Call your healthcare provider right away if you, your child, or the person you are caring for has a seizure while taking Lupron Depot or Lupron Depot-Ped.

May increase the risk of psychiatric events or mood changes, such as emotional lability (eg, crying, irritability, impatience, anger, and aggression). Call your healthcare provider at once if you, your child, or someone you are caring for has unusual changes in mood or behavior. 

Increased pressure in the fluid around the brain (Pseudotumor Cerebri) can happen in people receiving GnRH agonist medicines such as Lupron Depot or Lupron Depot-Ped. Call your healthcare provider right away if you, your child, or the person you are caring for has any of the following symptoms during treatment:

  • headache
  • eye problems, including blurred vision, double vision, or decreased eyesight
  • eye pain
  • ringing in the ears
  • dizziness
  • nausea.

There is an increased risk of developing diabetes in people receiving GnRH agonists such as Lupron Depot. Your doctor will monitor your blood glucose level and manage any changes according to guidelines.

Lupron Depot can harm an unborn baby or cause birth defects. Do not use it if you are pregnant or breastfeeding.

Lupron Depot or Lupron Depot-Ped may cause an allergic reaction. Get emergency medical help if you develop signs of an allergic reaction such as hives, sweating, fast heartbeats, dizziness, difficulty breathing, swelling in your face or throat, or a severe skin reaction which may include a red or purple skin rash that spreads and causes blistering and peeling.

Also, call your healthcare provider at once if you have:

  • A sudden severe headache
  • A wheezing, dry cough, or hack
  • Bone pain
  • Heart attack symptoms – chest pain or pressure, pain spreading to your jaw or shoulder, nausea, sweating; or
  • High blood sugar, symptoms may include increased thirst, increased urination, hunger, dry mouth, or fruity breath odor
  • Loss of movement in any part of your body
  • Muscle weakness or loss of use, loss of bowel or bladder control
  • Pain or unusual sensations in your back, numbness, weakness, or tingly feeling in your legs or feet

  • Sudden chest pain or discomfort
  • Swelling
  • Unusual changes in mood or behavior (crying spells, anger, feeling irritable)
  • Vomiting.

This is not a complete list of side effects and others may occur. Call your doctor for medical advice about side effects. You may report side effects to the FDA at 1-800-FDA-1088.

How does Lupron Depot work?

Lupron Depot (leuprolide acetate) works by suppressing the body’s production of certain hormones through a process called “chemical castration” or “medical castration.” This creates a temporary state of low sex hormones, which can be beneficial for treating conditions that are stimulated or worsened by these hormones.

Mechanism of Action: Lupron is a gonadotropin-releasing hormone (GnRH) agonist. When first administered, it briefly stimulates the pituitary gland to release luteinizing hormone (LH) and follicle-stimulating hormone (FSH).

Down-regulation: With continuous use, Lupron causes desensitization and down-regulation of GnRH receptors in the pituitary gland. This leads to a dramatic decrease in the production of LH and FSH.

Hormone Suppression: The reduction in LH and FSH leads to significantly decreased production of sex hormones (testosterone in men, estrogen in women).

  • In men: Testosterone levels drop significantly
  • In women: Estrogen levels decrease substantially.

Before taking this medicine

Do not use Lupron Depot or Lupron Depot-Ped if you are allergic to leuprolide or similar medicines such as buserelin, goserelin, histrelin, or nafarelin; Lupron Depot, Lupron Depot-Ped, any of the inactive ingredients in the injection, or if you have abnormal vaginal bleeding that a doctor has not checked.

Certain brands or strengths of leuprolide are used to treat only men and should not be used in women or children. Always check your medicine to make sure you have received the correct brand and strength. Ask the pharmacist if you have any questions about the medicine you receive at the pharmacy.

To make sure Lupron Depot is safe for you, tell your healthcare provider about all your medical conditions including if you have ever had:

  • depression, mental illness, or psychosis
  • seizures or epilepsy
  • a blood vessel disorder
  • a brain tumor or spinal cord injury
  • heart disease, congestive heart failure, long QT syndrome
  • an electrolyte imbalance (such as low levels of potassium or magnesium in your blood) or
  • risk factors for bone loss (personal or family history of osteoporosis, smoking, alcohol use, taking steroid or seizure medicines long term).

Call your doctor if your periods continue while you are being treated with this medicine.

Do not give this medicine to any child without medical advice.

Pregnancy and Breastfeeding

Lupron Depot usually causes women to stop ovulating or having menstrual periods. However, you may still be able to get pregnant. Leuprolide can cause birth defects and should not be used if you are pregnant. Use a condom or diaphragm with spermicide to prevent pregnancy because leuprolide can make hormonal birth control less effective. Tell your doctor right away if you inadvertently become pregnant.

You should not breastfeed while using leuprolide.

Leuprolide may cause infertility, although research shows full reversibility of fertility suppression when leuprolide is discontinued after continuous administration for up to 24 weeks. Lupron may be used to delay egg release for IVF treatment.

How is Lupron administered?

Initially, Lupron Depot must be administered under the supervision of a healthcare provider, although some people can be taught how to self-administer it themselves.

  • Lupron Depot is given into a muscle.
  • The dosing schedule varies depending on the condition being treated but it may be every 1, 3, 4, or 6 months.

Different brands or strengths of leuprolide are used to treat different conditions.

  • Always check your medication to make sure you have received the correct brand and type prescribed by your doctor.

You may need frequent medical tests while using this medicine.

Keep all scheduled visits to the doctor. If a scheduled dose is missed, the person receiving Lupron Depot or Lupron Depote-Ped may start having symptoms or signs of puberty again.

  • Your healthcare provider will do regular exams and blood tests.
