Copper IUD (Paragard)
The Copper IUD (Paragard) is a long-term contraceptive device made of copper and plastic that is placed inside the uterus to prevent pregnancy. Studies have found that it is highly effective for emergency contraception compared to levonorgestrel, another form of emergency contraceptive. Additionally, research has noted potential side effects such as increased menstrual bleeding and pain, though these can vary among users. Copper IUDs are also known to be less likely to cause hormonal side effects compared to hormone-releasing IUDs. However, some individuals may experience copper hypersensitivity, which can lead to allergic reactions or discomfort. While the device is generally well-tolerated and effective, individual experiences can differ significantly.
