The Copper T IUD is a method of contraception that lasts up to ten years after insertion. It is considered 99% effective in preventing pregnancy and contains no hormones. Women who are looking for a long term method of pregnancy prevention that does not contain hormones may find the Copper T is the best method of contraception for them. The Copper T is inserted into the uterus and insertion is easier if done during the menstrual period and if the woman has had at least one vaginal delivery. However, women who have never been pregnant are still candidates for the Copper T.
Women who use the Copper T may experience side effects. These side effects can include:
• Heavy menstrual bleeding
• If heavy menstrual bleeding occurs regularly, anemia is possible
• Menstrual cramps
• Changes in menstrual cycle
• Women who are not in monogamous relationships may be more susceptible to infection.
• Nausea
• Vomiting
Heavy periods usually resolve within a few months after Copper T insertion. Menstrual cramps can usually be resolved with over the counter pain medication. Because the Copper T does not protect against sexually transmitted infections, women who are not in monogamous relationships should use condoms with each sexual encounter.
Side effects are not the same as complications. Complications can be rare with the Copper T. Complications include spontaneous expulsion of the Copper T, miscarriage if the woman is already pregnant at the time of Copper T insertion, tear in the uterine wall.
A very rare side effect that a woman should be screened for prior to Copper T insertion is an allergy to copper. Signs that a woman is allergic to copper after insertion include itching and a rash in the vagina or genital area. If this happens, a woman should see her health care provider immediately for prompt removal of the Copper T.
