Longact (Loop)

intrauterine contraceptive device  

Longact (Loop)

Longact intrauterine contraceptive device (IUCD) is a small, t-shaped flexible plastic frame with horizontal and vertical arms. The vertical arm has a copper wire wrapped around it and two colored threads at the lower end. Copper ions from the IUD create an environment that causes sperm to break apart. The nylon threads (tail), which stick out through the cervix into the vagina, allows the woman to check whether the IUD is in place or not. Longact is effective for up to 12 years. It can also be used as emergency contraception.


Longact IUCD is one of the most effective contraceptive methods. As typically used, only 0.7% of women become pregnant in the first year of use.
