The most common side effects of PARAGARD are heavier, longer periods and spotting between periods. For most women, these side effects diminish after 2 to 3 months. However, if your period continues to be heavy or long, or spotting continues, contact your healthcare professional.
Infrequently, serious side effects may occur, including pelvic inflammatory disease (PID), difficult removals (surgery may sometimes be needed to remove PARAGARD), perforation of the uterine wall, or expulsion of PARAGARD from the uterus.
This is not a complete list of possible side effects. Be sure to discuss all the risks and safety information with your healthcare professional.
