Having an IUD inserted is frightening for many women. On forums and social media, testimonies range from "I didn't feel a thing" to "the worst pain of my life." This disparity creates legitimate anxiety. To be honest, about 80% of women experience moderate to severe pain during insertion according to a study in the British Medical Journal. For decades, this pain was downplayed by the medical profession with the simple recommendation "take a Doliprane." But things are changing. In August 2024, the US CDC published new recommendations finally recognizing that The pain of the pose should be taken seriously and managed medicallyThis article tells you the truth about pain, the anesthesia options available, and how best to prepare.
The main thing to remember
- 80% of women experience moderate to severe pain during insertion (BMJ study)
- The pose lasts 5 to 15 minutes, but the most intense pain lasts only a few seconds
- anesthesia options exist : local lidocaine, paracervical block, sedation (rarely offered in France)
- The women nulliparous (without children) statistically have more pain than those who have given birth
- Ibuprofen alone does not work against the pain of laying (formal studies)
- New CDC 2024 recommendations: lidocaine should be offered routinely
- Posing during menstruation doesn't change much to pain (persistent myth)
The Truth About IUD Insertion Pain
For years, healthcare professionals downplayed the pain of insertion, claiming it was "like period pain" or "it only lasts a few seconds." This systematic downplaying created a gap between women's actual experience and what they were told.
The Numbers Nobody Tells You
A study published in the British Medical Journal objectively measured the pain experienced by women during IUD insertion on a visual analogue scale of 0 to 100.
Study results
- 64,8/100 : Average pain score reported by patients
- 35,3/100 : Pain score estimated by doctors (almost 2 times less!)
- 17% nulliparous women experienced pain requiring medical management
- 11% women who had already given birth needed painkillers during or after
- 38% women report more menstrual pain with IUD in the first 3 months
This gap between the pain felt and that perceived by caregivers explains why so many women feel betrayed or not listened to after an operation.
Where Does Pain Come From?
To understand pain, we need to break down the steps of the pose. Each step causes a different type of pain.
The most intense pain occurs during the 10 to 30 seconds when the IUD passes through the cervix and expands into the uterus. This pain comes from uterine contractions (cramps) and forced dilation of the cervix.
Why Some Women Have More Pain Than Others
Pain varies greatly from one woman to another. Several anatomical and physiological factors explain it.
Factors that increase pain
- Nulliparity (never given birth vaginally): the cervix is tighter and less dilated
- Retroverted uterus (tilted backwards): makes insertion more technically difficult
- Cervical stenosis : very narrow or scarred cervix
- Significant anxiety : stress increases the perception of pain and can contract the uterus
- History of vaginismus or gynecological pain
- Endometriosis : increased uterine sensitivity
- Practitioner experience : a less sure gesture prolongs the pain
Testimonials: The Diversity of Experiences
IUD insertion experiences range from painless to traumatic. This variability is normal and reflects differences in anatomy and pain threshold.
Laura, 28 years old (nulliparous): "I had a copper IUD inserted without anesthesia because my gynecologist told me it wasn't necessary. It felt like a knife was being stabbed into my stomach. I almost threw up and started crying. The pain lasted about 20 seconds, but I had cramps for three days afterward. If I had to do it again, I would insist on anesthesia."
Sophie, 35 years old (2 children): "Honestly, I barely felt the insertion. A slight cramp when the IUD went in, but nothing unbearable. Less painful than a blood test. I think having given birth twice has made my cervix more flexible."
Amélie, 24 years old (nulliparous, with lidocaine): "I was very scared because of the testimonials on the forums. My midwife suggested a lidocaine block. I felt the sting (unpleasant but bearable), then nothing during the procedure itself. I just felt a feeling of pressure. The cramps afterward lasted 2 hours, manageable with ibuprofen."
Marie, 31 years old (1 child): "The insertion went badly. The IUD wouldn't fit, and the gynecologist had to do it several times. I felt dizzy and almost fainted. It lasted 15 minutes instead of 5. Traumatic. I had it removed 6 months later and I'll never have an IUD again."
Anesthesia and Pain Management Options
For a long time, the only recommendation was to take ibuprofen 1 hour before the procedure. However, studies show that ibuprofen alone does not significantly reduce the pain of the procedure. Fortunately, other options exist.
The New CDC Recommendations 2024
In August 2024, the US Centers for Disease Control and Prevention (CDC) issued landmark recommendations after years of pressure from patients on social media (notably TikTok). For the first time, an official medical body acknowledged that pain must be managed.
CDC 2024 Key Recommendations
- All professionals must inform patients about potential pain before the installation
- Un personalized pain management plan must be established with each patient
- Lidocaine (paracervical or topical block) "may be useful" to reduce pain
- Misoprostol is not more recommended routinely (it dilates the cervix but increases cramps)
- The approach must be patient-centered, not on the comfort of the practitioner
These recommendations are a major step forward, but they remain cautious ("may be useful" rather than "should be routinely offered"). In practice, only 5% of IUD insertions in the United States involve documented anesthesia, according to a 2025 study.
Complete Overview of Available Options
Lidocaine Paracervical Block: How It Works
This is the most effective local anesthesia option according to studies. It involves injecting 10 to 20 ml of 1% or 2% lidocaine into the cervix.
Paracervical block procedure
- Lidocaine injection at 2 to 4 points around the cervix
- The injection itself may sting (moderate pain, 10 seconds)
- Wait 3 to 5 minutes for the anesthesia to take effect
- The cervix is numb, the pain in the tenaculum is greatly reduced
- Uterine cramps remain present but are reduced
⚠️ Lidocaine limit
Lidocaine anesthetizes the cervix, but it does not completely prevent uterine cramping that occurs during the passage and deployment of the IUD. This is why even with anesthesia, some women still experience pain.
For cramps, NSAIDs or sedation are more effective, but these options are almost never offered in France.
The Complete Installation Process
Knowing exactly what's going to happen helps reduce anxiety. Let's break down each step of the process.
Before Installation: The Consultation
A preliminary consultation is mandatory. The practitioner checks that you are a good candidate and chooses the type and taille of a suitable IUD.
What is checked during the consultation
- No current pregnancy (test if necessary)
- Absence of active genital infection
- Taille and position of the uterus (gynecological examination)
- Possible contraindications (uterine malformation, copper allergy, etc.)
- Choice between copper or hormonal IUD depending on your profile
- Choice of taille (short for nulliparous women or those with a narrow uterus)
This is the time you should ask ALL your questions about pain and ask about available anesthesia options.
D-Day: Step by Step
Complete timeline of the installation (5 to 15 minutes)
1. Installation (1 minute)
Gynecological position (as for a pap smear). Some practitioners perform insertion during menstruation because the cervix is slightly more open, but this is not mandatory and does not significantly change the pain.
2. Placement of the speculum (30 seconds)
Like a smear test. Discomfort but no pain.
3. Disinfection of the cervix (30 seconds)
Application of an antiseptic. Sensation of cold, no pain.
4. [Optional] Local anesthesia (3-5 minutes)
If paracervical block: lidocaine injection. Moderate stinging. Wait 3-5 minutes for the anesthesia to take effect.
5. Tenaculum clamp application (5 seconds)
Clamp that holds the cervix still. Sharp pinching painThis is one of the most painful steps if there is no anesthesia.
6. Measurement of the uterus with a hysteroscope (10-20 seconds)
Thin probe that measures the depth of the uterus. Deep cramp, uncomfortable feeling of pressure.
7. Insertion of the IUD into the uterus (10-30 seconds)
The device passes through the cervix and enters the uterus. Severe crampThis is the most painful moment for many.
8. Deployment of the IUD arms (2-5 seconds)
The arms of the T open. Very intense but brief crampSome women describe a sensation of "electric shock."
9. Removal of the applicator and tenaculum (10 seconds)
Immediate relief as soon as the clamp is removed.
10. Cutting the wires (10 seconds)
The IUD strings are cut 1-3 cm from the cervix. No pain.
Just After the Pose
The intense pain lasts only a few seconds, but moderate cramps often persist for several hours.
- Stay lying down for 5 to 10 minutes after application (risk of vagal discomfort)
- Moderate cramps for 2 to 6 hours afterwards (normal)
- Spotting (light bleeding) for 1 to 3 days
- Get someone to drive you home if possible (10% of women experience dizziness)
- Plan a quiet day, avoid intense physical activities
Manage post-insertion bleeding with peace of mind
Spotting and irregular bleeding are common in the first few months after insertion. Period Panties offer discreet and comfortable protection.
How to Prepare for Posing to Minimize Pain
Proper preparation can significantly reduce anxiety and, to a lesser extent, pain. Some strategies work better than others.
What Works (Proven by Studies)
- Request a paracervical lidocaine block : the only truly effective method
- Take 500mg of naproxen sodium 1 hour before (not ibuprofen): reduces cramps after
- Breathe deeply during the pose : abdominal breathing reduces spasms
- Choose an experienced practitioner : a quick and safe gesture = less pain
- Anxiolytic if significant anxiety : does not reduce pain but helps to bear it
- To be accompanied : reassuring presence, help with return
Myths That Don't Work
Misconceptions dismantled by studies
- ❌ Taking a break during menstruation reduces pain : false, the pain is the same
- ❌ Ibuprofen before installation helps : false, no effect on insertion pain
- ❌ Misoprostol makes insertion easier : yes to dilate the cervix, but increases cramps
- ❌ Coughing during insertion reduces pain : no scientific evidence
- ❌ "It doesn't hurt any more than a blood test." : false for 80% of women
Checklist Before Your Appointment
1 week before
- Contact the office to ask if local anesthesia is available
- If not offered, ask for a prescription for an anxiolytic if you are very anxious
D-Day - 1 hour before
- Take 500mg of naproxen sodium (Naprosyn, Apranax) with food
- Eat lightly (risk of nausea if vagal discomfort)
Just before laying
- Empty your bladder
- Breathe calmly, try to relax your pelvic muscles
- Don't hesitate to ask for a break if you need one.
After installation
- Bring a hot water bottle for cramps
- Ibuprofen 400mg every 6 hours if needed for 24-48 hours
- Quiet day, no sports or heavy lifting
Warning Signs After Installation
Moderate cramps and spotting are normal for a few days. However, some symptoms require prompt attention.
Consult quickly if you present
- Severe pain who do not respond to painkillers after 48 hours
- Fever > 38°C in the days following installation (risk of infection)
- Very heavy bleeding (more than one protection every hour)
- Foul-smelling vaginal discharge (sign of infection)
- Persistent discomfort, fainting, severe dizziness
- You feel the hard plastic of the IUD in your vagina (partial expulsion)
