Most IUDs are placed in a quick office visit with nothing stronger than an over-the-counter painkiller, even though numbing options for the cervix exist. The reason has less to do with the medicine failing than with how the pain has been judged by the people doing the procedure.1PubMed. Gender Bias in Pain Management: The Case for Updating Analgesia Guidelines for Intrauterine Device Insertion Procedures That is starting to change, and you can request pain control rather than wait to be offered it.
Why Pain Relief Isn’t Routine
Patients rate their insertion pain well above what their providers believe they saw, so providers tend to underestimate how much the procedure hurts.2PubMed. Patients’ experiences and providers’ observations on pain during intrauterine device insertion3PubMed. Patients’ experiences and providers’ observations on pain during intrauterine device insertion Some doctors say the pain is minimal or over too quickly to need treating.4PubMed. Barriers and facilitators for providing pain control during intrauterine device insertion: a multi-center physician survey But short pain can still be severe, and it can make people put off or avoid future care.
Bias has shaped this gap. About 70% of women report moderate to severe pain, yet only about 30% of physicians offer anesthesia.5PubMed Central. A Literature Review on Pain Management in Women During Medical Procedures: Gaps, Challenges, and Recommendations Medicine has long portrayed women as exaggerating symptoms, which leads to underestimating their pain, often without anyone intending it.6PubMed Central. A Literature Review on Pain Management in Women During Medical Procedures: Gaps, Challenges, and Recommendations
Pain at insertion varies widely, so a clinician who has placed many easy IUDs may truly not have seen how bad it can be for some. And because pain is hard to see from outside, patients often stay quiet or grit their teeth.
Practical and policy barriers add to it. Some physicians cite logistical barriers such as time and equipment.7PubMed. Barriers and facilitators for providing pain control during intrauterine device insertion: a multi-center physician survey IUD insertions are usually booked into short appointment slots, and a numbing injection or waiting for a spray to take effect adds minutes to each one. Offices also have to stock supplies and train staff, which is easy to put off when no one is asking.
Cost matters too. Insurers can refuse to cover anesthesia for contraceptive procedures, and its cost can range from about $200 to $3,500.8CT Mirror. Opinion: CT should mandate insurance coverage for anesthesia for reproductive health procedures Most of that price belongs to sedation, which needs extra staff, monitoring, and recovery time. Numbing medicine is cheap and given by the person placing the IUD.
In August 2024 the CDC added pain-management guidance for IUD insertion to its contraception recommendations.9PubMed. Evaluating changes in lidocaine and opioid administration on the day of IUD insertion, 2018-2025 After that update, the odds of a patient receiving lidocaine numbing at insertion rose by about 18%.10medRxiv. Evaluating Changes in Pain Medication Administration During IUD Insertion, 2018-2025 Offering pain relief is becoming more common but is still far from universal.
If you want it, say so plainly: “I’d like pain control for the insertion; what do you offer?” That is a normal request, and it puts the options on the table. If the clinician says most people tolerate it fine, you can reply that you’d still like to use something, since tolerating a procedure and being comfortable during it are different things. A “no” often means “we don’t stock it here” rather than “you don’t need it,” so asking where else it’s available is a fair follow-up.
How Much IUD Insertion Hurts and Who Feels It Most
The clinician holds the cervix with a clamp, measures the womb, then places the device. Pain tends to be highest right after the device goes in.11PubMed. 10% lidocaine spray for pain control during intrauterine device insertion: a randomised, double-blind, placebo-controlled trial The cervix and the womb send pain signals along different nerve pathways, so numbing the cervix doesn’t reach all of it.12PubMed Central. Lidocaine-Prilocaine Cream as Analgesia for IUD Insertion: A Prospective, Randomized, Controlled, Triple Blinded Study
The clamp grips tissue that is sensitive to pressure, so it often feels like a sharp pinch. Passing the device through the cervical opening and into the womb tends to bring a deeper, crampy ache, like a strong period cramp, which usually eases within minutes.
Some people feel more than others. Among women who had never been pregnant, severe period pain was the one thing that strongly predicted a painful insertion.13Obstetrics & Gynecology. Predicting Painful or Difficult Intrauterine Device Insertion in Nulligravid Women About 60% of people who haven’t given birth report moderate to severe pain.14CT Mirror. Opinion: CT should mandate insurance coverage for anesthesia for reproductive health procedures Anxiety and strong emotional reactions are linked to higher pain.15Clinical and Experimental Obstetrics & Gynecology. A psychological factor associated with pain during intrauterine device insertion: emotional reactivity16PubMed. Anxiety and pain from office intrauterine device insertion: Relationship to prior social media use
Some people also feel faint, sweaty, or nauseated during insertion, a reaction more common in a first insertion and closely tied to stronger pain.17PubMed. Syncope and other vasovagal reactions at interval insertion of Lippes Loop D–who is most vulnerable? It is a reflex to the cervix being stimulated, which can briefly lower heart rate and blood pressure. It usually passes within minutes when you lie flat and rest, and it doesn’t mean the insertion went wrong. Reducing pain can also lower the chance of fainting.18PubMed. Syncope and other vasovagal reactions at interval insertion of Lippes Loop D–who is most vulnerable?
Your history is useful here. Tell your clinician if your periods are very painful or if you have fainted during procedures or blood draws. Those are good reasons to ask for numbing in advance, and they let the clinician slow down, keep water and a place to rest ready, and take extra care with pain control.
Numbing Options That Work in the Office
A paracervical block is lidocaine injected around the cervix to numb it before insertion. In people who had never given birth, it cut median pain during placement from about 54 to 33 on a 100-point scale.19PubMed Central. Paracervical Block for Intrauterine Device Placement Among Nulliparous Women: A Randomized Controlled Trial It lowered pain at every step and raised satisfaction compared with a fake injection.20PubMed. A double-blind, triple-arm randomized controlled trial of 1% lidocaine paracervical block for intrauterine device (IUD) insertion Across 11 trials, lidocaine at the cervix or womb lowered pain by about 1 point on a 10-point scale.21PubMed. Uterine or paracervical lidocaine application for pain control during intrauterine contraceptive device insertion: a meta-analysis of randomised controlled trials
The process is simple. After the cervix is exposed and cleaned, the clinician injects lidocaine in one or more spots around it, often near where the clamp will go. You may feel a pinch or brief burning, though in one trial the shot itself rated only about 1 out of 10.22PubMed. A double-blind, triple-arm randomized controlled trial of 1% lidocaine paracervical block for intrauterine device (IUD) insertion The clinician usually waits a few minutes for it to work before placing the clamp. That wait is part of why it isn’t always done.
The injection numbs the cervix, so it works best on the clamp and on the passage through the cervical opening. The womb has its own nerve supply, so the cramp as the device settles can still come through. That explains why trials found a real but modest average drop, and why some people say it helped a lot while others say it only took the edge off. Numbing lowers pain but rarely removes it, and combining it with other steps helps more.
Sprays and creams skip the needle. Lidocaine 10% spray on the cervix lowered overall pain from about 3.2 to 1.0 out of 10 in one trial.23PubMed. Lidocaine 10% spray to the cervix reduces pain during intrauterine device insertion: a double-blind randomised controlled trial Lidocaine-prilocaine cream roughly halved pain at each step in women who had given birth, with no reported side effects.24PubMed. Effect of cervical lidocaine-prilocaine cream on pain perception during copper T380A intrauterine device insertion among parous women: A randomized double-blind controlled trial The spray goes directly on the cervix once it is visible, followed by a brief wait. The cream is placed on or in the cervix and needs a few minutes to soak in. If injections worry you, these are worth asking about.
The injection has the most evidence for lowering pain at placement. Which option you get often depends on what the clinic stocks. Ask when booking, since it may need to be ready, and if the clinic offers none, ask about clinics that do.
Painkillers, Cervix Softeners, and Sedation
Several doses of ibuprofen before insertion lowered pain from about 7 to 5 out of 10 in one trial.25PubMed. Multidose Ibuprofen Prior to Intrauterine device insertion (MIPI): a triple blinded randomized controlled trial Overall, though, pain pills taken ahead give limited relief for most women.26PubMed. Efficacy of NSAIDs in reducing pain during intrauterine device Insertion: A systematic review If your clinician agrees, take one about an hour before. It helps more with cramps afterward than with the moment itself, and you can ask about prescription options like naproxen.
Misoprostol, a pill that softens the cervix, makes little to no difference to insertion pain.27PubMed Central. Misoprostol for intrauterine device placement It can cause nausea, cramps, shivering, and fever.28Middle East Fertility Society Journal. The value of misoprostol administration before intrauterine contraceptive device insertion: a systematic review and meta-analysis It may help people who recently had a failed insertion attempt.29Cochrane Database of Systematic Reviews. Misoprostol for intrauterine device placement
Conscious sedation is medicine that relaxes you while you stay awake, and it is offered at some centers.30PubMed. IUD Insertion Under Conscious Sedation: Patient Characteristics with Clinical Decisions At one teen clinic, about 93% of insertions under sedation succeeded.31PubMed. IUD Insertion Under Conscious Sedation: Patient Characteristics with Clinical Decisions You can respond to the clinician but feel relaxed and often remember little. It is given through an IV or by mouth, depending on the setting, and you are monitored during and after. General anesthesia, where you are fully unconscious, isn’t typically used for an IUD. Evidence for laughing gas is unclear.32Women. Use of Local Anesthetic Agents and Conscious Sedation in Intrauterine Device Insertion: A Systematic Review Anti-anxiety medicine can be offered to people with strong anxiety.33PubMed. Best practices for reducing pain associated with intrauterine device placement
Sedation is usually offered in hospital or specialty settings, so expect to need a ride home and check insurance coverage first. People with severe anxiety, a history of trauma, or a past insertion that couldn’t be completed or was extremely painful have good reasons to ask about it. Teens and people with certain medical conditions are sometimes referred for sedation as well.
Non-Drug Ways to Ease the Pain
Overall, non-drug methods lowered pain and raised satisfaction.34PubMed. Effects of Nonpharmacological Interventions on Pain and Patient Satisfaction During Intrauterine Device Insertion: A Systematic Review and Meta-Analysis Virtual reality, distraction, music, and acupuncture showed benefit.35PubMed. Effects of Nonpharmacological Interventions on Pain and Patient Satisfaction During Intrauterine Device Insertion: A Systematic Review and Meta-Analysis Many single methods showed no difference in trials.36PubMed Central. Non-pharmacologic techniques for interval intrauterine device placement: a systematic review Calming language and surroundings are recommended to lower anxiety.37PubMed. Best practices for reducing pain associated with intrauterine device placement Since single methods often showed no difference, treat these as extras that make the visit easier, not substitutes for numbing.
You can bring headphones with music or a podcast, and ask the clinician to tell you each step. During the clamp, try a slow exhale and relax your belly and thighs. You can ask to pause if you need to.
Having someone you trust in the room can help you feel calmer, and you can ask the clinic ahead of time whether that is allowed. They can hold your hand, remind you to breathe, and speak up if you freeze. Agree beforehand on a signal or phrase that means you need a pause.
Cramping After an IUD and When to Call
The strongest cramping fades within minutes.38University of Utah Health. IUD Insertion Pain: What To Expect and How to Manage It Period-level cramps can then last up to a week.39University of Utah Health. IUD Insertion Pain: What To Expect and How to Manage It Heating pads, acetaminophen, or ibuprofen help.40University of Washington Department of Obstetrics and Gynecology. IUD Aftercare Instructions Ibuprofen works best taken when pain appears, so keep some within reach.41PubMed Central. Management of pain associated with the insertion of intrauterine contraceptives Acetaminophen is an option if you can’t take ibuprofen, and you should follow the label’s dosing.
After the first few minutes, cramping usually settles into an on-and-off ache like a period, often low in the belly or back. It tends to be strongest the first day or two and gradually eases. Spotting or irregular bleeding are also common in the first weeks and aren’t by themselves a sign of a problem. Heat on the lower belly relaxes the muscle and can be used alongside medicine.
Cramping past a week can be a sign the IUD moved, so see your doctor.42University of Utah Health. IUD Insertion Pain: What To Expect and How to Manage It Cramping that gets worse instead of better after the first days is also a reason to call. Fever, heavy bleeding, foul-smelling discharge, or severe pain are not typical and need prompt attention. Because the IUD can shift, the clinic may need to check that the strings are present and the device is in place.
