Lupron Depot-3 Month IM Side Effects

Hot flashes (flushing), increased sweating, night sweats, tiredness, headache, upset stomach, breast changes, acne, joint/muscle aches, trouble sleeping, reduced sexual interest, vaginal discomfort/dryness, abnormal vaginal bleeding (in girls), swelling of the ankles/feet, dizziness, or mild burning/pain/bruising at the injection site may occur. If any of these effects persist or worsen, tell your doctor or pharmacist promptly.

When this medication is used regularly, it is expected that the menstrual period will stop (or decrease to light bleeding/spotting). Menstrual periods usually return within 3 months after treatment is stopped. Tell your doctor promptly if regular periods continue during treatment with leuprolide.

During the first few weeks of treatment, your hormone levels will actually increase before they decrease. This is a normal response by your body to this drug. This may result in a temporary worsening of your symptoms for a few weeks.

Remember that your doctor has prescribed this medication because he or she has judged that the benefit to you is greater than the risk of side effects. Many people using this medication do not have serious side effects.

Tell your doctor immediately if any of these unlikely but serious side effects occur:

  • mental/mood changes (e.g., new or worsening depression, thoughts of suicide, mood swings, memory problems, aggression in children)
  • bone pain (in adults)
  • easily broken bones (in adults)


Rarely, a very serious problem with your pituitary gland (pituitary apoplexy) may occur, usually in the first hour to 2 weeks after your first injection. Seek immediate medical attention if any of these very serious side effects occur:
