"Medina IUD" - Clarification Needed
There is no FDA-approved or recognized intrauterine device called the "Medina IUD" in current medical literature or contraceptive guidelines. This term does not appear in the U.S. Medical Eligibility Criteria for Contraceptive Use or standard contraceptive references 1.
Currently Available IUD Types
The established IUD categories recognized by the CDC include 1:
- Copper-bearing IUD (Cu-IUD): Contains copper, provides contraception for up to 10 years 2
- Levonorgestrel-releasing IUD (LNG-IUD): Releases 20 μg/24 hours of progestin, effective for 5 years 2, 3
Possible Explanations
You may be referring to:
- Mirena IUD: A levonorgestrel-releasing device that is commonly used and may be phonetically confused with "Medina" 2
- A regional or brand name: Some countries use different commercial names for standard IUD devices
- A misspelling or miscommunication: The term may have been misheard or incorrectly transcribed
Standard IUD Contraceptive Mechanism
Both recognized IUD types work primarily by preventing fertilization rather than implantation 3. The copper IUD is immediately effective upon insertion and requires no backup contraception 4. The contraceptive efficacy is approximately 97%, with failure rates of 0.8% for copper IUDs and 0.1-0.2% for progestin IUDs in the first year 5.
Critical Safety Information
Absolute contraindications for any IUD include 1, 4:
- Pregnancy (Category 4 - unacceptable health risk due to serious pelvic infection and septic spontaneous abortion risk)
- Current pelvic inflammatory disease
- Puerperal or post-septic abortion infection
Relative contraindications include 1, 4:
- High risk for STIs at time of insertion (Category 3 for emergency contraception)
- Unexplained vaginal bleeding 2
Recommendation for Clarification
Verify the exact name and type of IUD being referenced before proceeding with insertion or counseling, as using incorrect device information could lead to improper patient education or contraceptive failure.
