Taking Depo-Provera for more than 2 years can increase the risk of serious long-term side effects, including bone mineral density loss (osteoporosis), intracranial meningiomas (a type of brain tumor), blood clots, vision problems, and menstrual irregularities. The medication may also cause mood changes such as severe depression, and it can take up to a year or more for fertility to return to normal after stopping. Due to these risks, current medical recommendations advise using Depo-Provera for 2 years or less unless other contraceptive methods are inadequate.

Key Long-Term Side Effects

• Bone mineral density loss: This can lead to osteoporosis, making bones brittle and prone to fractures, even with minor injuries or falls.
• Intracranial meningiomas: Studies show that using Depo-Provera for over a year significantly increases the risk of developing these brain tumors, which can cause neurological symptoms like headaches, seizures, vision problems, and personality changes.
• Blood clots and cardiovascular risks: There is an increased risk of blood clots and associated complications.
• Mood and mental health effects: Including severe depression, anxiety, and mood swings.
• Delayed fertility: Fertility may take up to a year to return after discontinuation of the drug.
• Other side effects: Weight gain, headaches, abdominal pain, and irregular menstrual bleeding.

Medical Recommendations

• The FDA and medical sources recommend that women do not use Depo-Provera for longer than 2 years due to these potential risks.
• Regular medical check-ups and bone density monitoring may be advised if longer use is necessary.
• Alternative contraception methods should be considered to avoid prolonged use risks.
