Copper Intrauterine Device Effectiveness After Insertion
The copper intrauterine device (Cu-IUD) provides contraceptive protection immediately after placement when it is inserted correctly and it is reasonably certain that the patient is not pregnant. [1]
No additional contraceptive protection is needed after Cu-IUD placement. [1]
Medication Selection Algorithm
Copper intrauterine device (Cu-IUD) is recommended for immediate contraceptive effect when pregnancy can be excluded. [1]
Key Evidence Supporting This Recommendation
The CDC Selected Practice Recommendations state that the Cu-IUD may be placed at any time if it is reasonably certain that the patient is not pregnant. [1]
The CDC Selected Practice Recommendations state that no additional contraceptive protection is needed after Cu-IUD placement. [1]
Monotherapy Versus Combination Therapy
Back-up contraception is not needed after Cu-IUD placement. [1]
Important Clarifications or Nuances
If the health care provider is not reasonably certain that the patient is not pregnant, a method other than an IUD should be used until pregnancy can be excluded and Cu-IUD placement is feasible. [1]
Initiation Thresholds or Indications
Cu-IUD placement is permissible at any time if it is reasonably certain the patient is not pregnant. [1]
Cu-IUD placement can also be used as emergency contraception when placed within 5 days after the first act of unprotected intercourse. [1]
Common Pitfalls to Avoid
Assuming immediate effectiveness without pregnancy exclusion is a common error when pregnancy status is uncertain. [1]
