Do Suppositories Hurt? Reasons & Tips for Comfort

For most people, inserting a suppository feels uncomfortable or awkward rather than genuinely painful. The brief sensation of pressure as the suppository passes through the anal sphincter lasts only a few seconds, and once it is fully inside the rectum, it typically causes little or no ongoing pain. That said, individual experiences vary widely depending on technique, existing conditions, the type of suppository, and even your state of mind going into it. Understanding why discomfort happens and how to minimize it makes the whole process considerably easier.

Why That Area Is So Sensitive

The anal canal is densely packed with nerve endings, which is why it can register even slight pressure or temperature changes. The rectum itself, located just above the anal canal, is far less sensitive to sharp or cutting sensations but responds strongly to stretching and distension. This is why the moment of insertion, when the suppository passes through the narrow, nerve-rich anal canal, tends to be the most noticeable part. Once the suppository is past that point and sitting inside the roomier rectum, most people feel little beyond mild fullness.

Not everyone’s rectal nerves respond the same way. Research on rectal sensory thresholds has found significant variation between individuals. In one study comparing people with chronic constipation to healthy volunteers, the pain threshold to electrical stimulation of the rectal mucosa was more than twice as high in the constipation group, with wide ranges in both groups.¹ This means two people can insert the exact same suppository and have very different experiences, and neither one is exaggerating. Your personal nerve sensitivity, your history of rectal conditions, and even whether you have had recent bowel movements all influence how much you feel.

Common Reasons Suppositories Cause Discomfort

When a suppository does hurt beyond the brief moment of insertion, there is usually a specific reason. Knowing the cause helps you decide whether you can fix the problem yourself or should talk to a doctor.

Hemorrhoids or fissures: Swollen hemorrhoids or small tears in the anal lining make the canal more sensitive and can turn a normally mild insertion into a sharp sting. If you have visible swelling, bleeding with bowel movements, or a known fissure, suppository use will likely be more uncomfortable until the underlying issue heals.
Pelvic floor tension: In hypertonic pelvic floor dysfunction, the muscles around the pelvis stay chronically contracted and tight. These short, spastic muscles restrict local blood flow, change the surrounding tissue pH, and trigger ongoing inflammation.² When the pelvic floor muscles cannot relax, the anal sphincter resists the suppository, and the resulting friction and pressure feel much worse than they would otherwise.
Irritating ingredients: Some suppositories contain active ingredients that are meant to stimulate the rectal lining. Bisacodyl laxative suppositories, for instance, work partly by irritating the mucosa to trigger contractions. That mild burning or cramping sensation is the drug working as intended, but it can catch people off guard. Glycerin suppositories tend to be gentler, though they can still cause a drawing or osmotic sensation as they pull water into the rectum.
Insufficient lubrication: A dry suppository dragging against the anal canal is one of the most common and most preventable sources of pain. The waxy coating on many suppositories provides some glide, but it is often not enough, especially if you tend toward dryness.
Temperature and hardness: A suppository straight from the refrigerator can feel shockingly cold and rigid. One that has been sitting in a warm bathroom may be too soft and crumble on contact. Both extremes make insertion harder and less comfortable than it needs to be.

The Insertion Debate: Pointed End or Blunt End First?

If you have ever read the instructions inside a suppository box, they almost certainly told you to insert the tapered, pointed end first. That seems intuitive, like feeding a bullet into a chamber. But a widely cited 1991 study in The Lancet challenged this conventional wisdom, finding that inserting the suppository blunt end (the flat base) first led to better retention. The researchers reasoned that the anal canal’s natural wave-like contractions and pressure gradient would push the suppository inward more effectively when the wider end entered first.³

A later nursing review examined the evidence base for this recommendation and found something revealing: the blunt-end-first advice traces back essentially to that single 1991 study, with no subsequent research replicating or expanding on it. Meanwhile, manufacturers’ instructions to patients almost universally still recommend pointed end first.⁴ So the evidence is thin either way. In practice, many nurses who have tried both methods report that base-first insertion does seem to reduce the urge to expel the suppository immediately, which matters for comfort because fighting that expulsion reflex is itself unpleasant. If the standard method has been uncomfortable for you, trying it the other way around is a low-risk experiment.

Practical Tips for a More Comfortable Experience

Most of the discomfort people associate with suppositories can be reduced or eliminated with small adjustments to preparation and technique. None of this is complicated, but the instructions that come with suppositories tend to be sparse.

Start with lubrication. Apply a small amount of water-based lubricant to the tip of the suppository and to the opening of the anus. This single step probably does more for comfort than anything else. Avoid petroleum-based lubricants if you are using a suppository with a water-soluble base, as they can interfere with how the suppository dissolves. If you do not have lubricant on hand, running the suppository briefly under cool water creates a thin wet layer that helps.

Positioning matters more than people realize. Lying on your left side with your right knee drawn up toward your chest is the standard recommendation in clinical settings, and it works well because it follows the natural curve of the lower colon and rectum. Squatting can also work, but it tends to tighten the pelvic floor muscles, which is the opposite of what you want. If lying down is not practical, leaning forward while standing with one foot elevated on a step can be a reasonable compromise.

Relax the sphincter before you begin. This sounds obvious, but most people tense up involuntarily at the prospect of rectal insertion. Taking a few slow, deep breaths and consciously releasing the muscles around the anus, the same way you would to begin a bowel movement, can meaningfully reduce resistance. Some people find it helps to bear down very gently as if starting to push, which briefly opens the sphincter enough to make insertion smoother.

Push the suppository in about one finger-length, roughly one inch past the sphincter. If it is not far enough in, the sensitive nerve endings in the anal canal will register it as a foreign object and trigger a strong urge to push it out. Getting it fully past the sphincter and into the less-sensitive rectum eliminates that constant nagging discomfort. After insertion, squeeze your buttocks together and stay still for a few minutes. For suppositories meant to be absorbed rather than expelled (like pain medications or anti-nausea drugs), remaining lying down for 15 to 20 minutes gives the suppository time to melt and the medication time to absorb.

Temperature also deserves attention. If you store suppositories in the refrigerator as many require, take one out and hold it in your hand for 30 seconds to a minute before use. You want it firm enough to hold its shape but not so cold that it shocks the tissue on contact. If a suppository has become too soft from heat, place it in the refrigerator for 10 to 15 minutes to re-firm it. Trying to insert a mushy suppository is messy and tends to require more manipulation, which means more time spent in the discomfort zone.

Suppositories in Children

Parents tend to dread giving their children suppositories, and the data reflects this. In a survey of parental attitudes toward different routes of medication, a clear majority (58%) rated the rectal route as the most unpleasant way to give medication to a child, far ahead of intramuscular injections (19%), intravenous (11%), and oral (9%).⁵ That parents considered a suppository worse than a needle in the arm says something about how deeply the idea bothers people, whether or not the child actually experiences significant pain.

The irony is that rectal medications in children sometimes work as well as or better than oral ones in terms of outcomes. A randomized trial comparing oral ibuprofen to rectal diclofenac for pain control after pediatric circumcision found that pain scores did not differ meaningfully between the two groups, but children who received the rectal suppository needed fewer rescue pain medications, had fewer side effects (10% vs. 30%), and slept better afterward.⁶ For young children who cannot swallow pills or who are vomiting, the rectal route can be the most reliable way to get medication in.

For children, all the adult comfort tips apply with a few additions. Use a smaller amount of lubricant appropriate to their size, and only insert the suppository about half a finger-length. Distraction genuinely helps: singing, watching a video, or even blowing bubbles can redirect a child’s attention away from the sensation. If a child is old enough to understand, explaining in simple terms what is going to happen and why tends to produce less distress than springing it on them. And speed matters: the faster the insertion, the less time spent in the uncomfortable phase. Hesitation and multiple attempts make the whole experience worse for everyone.

How Your Expectations Change What You Feel

Here is something that might reshape how you think about suppository discomfort: what you expect to feel genuinely changes what you do feel. Research on visceral pain, meaning pain from internal organs including the gut, has demonstrated that both positive and negative expectations measurably alter the pain experience. In a study of healthy women exposed to identical rectal stimuli, those who were led to expect more pain reported significantly higher pain levels, while those told to expect relief reported less. The expectation of pain also triggered a real physiological stress response, with increased anxiety before the stimulus even arrived.⁷

This is not about imagining the pain away. It is a well-documented neurological phenomenon where anxiety primes the nervous system to amplify incoming signals. If you approach a suppository expecting it to be awful, your body tenses up, your sphincter contracts, and your brain is already interpreting mild pressure signals as pain before anything has happened. The inverse is also true: if you have had one comfortable insertion, you tend to be more relaxed the next time, and the experience gets progressively easier. People who use suppositories regularly for chronic conditions almost universally report that the first few times were the worst and that it becomes unremarkable with practice.

When the Rectal Route Has Real Advantages

Nobody chooses a suppository for fun, so it is fair to ask why they exist at all when pills seem so much simpler. The rectal route bypasses several problems that oral medications run into. If you are vomiting or nauseated, a pill is useless because it will not stay down long enough to absorb. If you are unconscious or unable to swallow, a suppository may be the only non-injection option. And some medications absorb more predictably through the rectal lining because they skip the liver’s first-pass metabolism, where oral drugs can be partially broken down before they ever reach the bloodstream.

For pain management in particular, rectal suppositories can hold their own against more invasive routes. A randomized trial in cancer patients compared a controlled-release morphine suppository to subcutaneous morphine injections and found no significant difference in pain control, sedation, or nausea between the two. Average pain intensity scores were identical, and patients used the same amount of rescue medication regardless of which route they were assigned to.⁸ For a patient who dreads needles or whose veins have been damaged by repeated injections, a suppository delivering equivalent pain relief is a meaningful option.

Anti-nausea medications like prochlorperazine and promethazine are among the most commonly prescribed suppositories precisely because nausea makes oral medication self-defeating. Fever-reducing suppositories (acetaminophen, ibuprofen) remain staples in pediatric care for the same reason. And for localized conditions like hemorrhoids, constipation, or inflammatory bowel disease flares, suppositories deliver the active ingredient directly to the affected area, which means lower systemic doses and fewer side effects elsewhere in the body.

Situations Where You Should Not Push Through the Pain

Mild pressure and brief discomfort are normal. Actual pain that persists, worsens, or includes bleeding is not. If inserting a suppository causes sharp pain that does not subside within a minute or two, stop. You may have an undiagnosed fissure, an abscess, or significant inflammation that needs medical attention before you continue using rectal medications. Forcing a suppository past damaged tissue can worsen a tear or introduce bacteria into a wound.

People who have recently had rectal or pelvic surgery should confirm with their surgeon before using suppositories, as healing tissue may not tolerate the mechanical pressure. Anyone undergoing chemotherapy or with a severely compromised immune system should be cautious as well, since the rectal lining can be thinned by treatment and more vulnerable to micro-tears. And if you experience persistent cramping or a strong urge to defecate that does not resolve after a non-laxative suppository has had time to absorb, the suppository may not have been inserted deeply enough and is sitting against the sensitive anal canal rather than in the rectum. In that case, gently pushing it further in with a lubricated finger usually resolves the issue.

If you consistently find suppositories unbearable despite proper technique and lubrication, mention it to your doctor or pharmacist. Compounding pharmacies can sometimes prepare the same medication in a smaller-diameter or differently shaped suppository, and for many drugs, alternative delivery routes exist. Rectal foams and enemas, for instance, deliver medication to similar areas but feel quite different from solid suppositories. There is rarely a situation where a suppository is the only possible option with no alternative worth discussing.
