The best hemorrhoid suppositories for internal swelling

A hemorrhoid suppository is for swelling and discomfort inside, especially at night. Preparation H suppositories are the ones most buyers try first. Calmol 4 is the gentler option when you do not want a numbing product and you can keep the box cool. If you do not want to insert anything, the Hemorrwedge cold pack rests on the outside and is the drug-free pick on this page.

Suppositories are the wrong first buy when the sore spot is on the skin you can see. That is a cream or ointment problem. Internal hemorrhoids, the ones inside the rectum, more often announce themselves with bleeding than with sharp pain. This page explains when a suppository makes sense, how to use one, and how strong the evidence is. Start with internal hemorrhoids if you are not sure which type you have, and with the best hemorrhoid products if you want the wider set.

The NHS instructions for hydrocortisone suppositories say they are for piles on the inside. Creams and ointments are for the outside ².

Our picks compared

Two of these are suppositories. The third is a cold pack for people who want relief without inserting a medicine.

Reviews of our picks

Buyer comments cluster around nighttime use for Preparation H, a gentler feel for Calmol, and short cold sessions for the pack. The complaints are mostly practical: foil, heat, and seams.

How we chose these hemorrhoid suppositories

The suppository aisle is smaller than the cream aisle. We kept the two with strong overall ratings from a large number of buyers and a clear split in the reviews. Preparation H is the one people already know, and recent comments say it helps most at night once the wrapper is open. The foil is stiff, some pieces arrive cracked, and a nightly habit uses them up. Calmol’s reviews say it soothes over a couple of days and the larger box lasts. The failure mode is heat: summer deliveries can arrive melted, and crumbled pieces are common enough to mention.

Hemorrwedge sits on this list as a cold pack, for people who have internal swelling and also want something drug-free for throbbing on the outside. Reviews praise the relief and the two-pack system. They also mention hard seams, packs that split later, and cold that is too intense without a cloth. Buyers say the cold lasts about 15 to 20 minutes. We did not pick by price. A product with a melted-in-transit problem stays on the list with that warning attached. No brand pays for a slot. Details are on the affiliate disclosure.

What the research says

Conservative care for hemorrhoids has long included suppositories. A widely cited review lists lifestyle changes, fiber, suppository-delivered anti-inflammatory drugs, and vein-toning medicines as the usual non-surgical start, and names bleeding with bowel movements as the most common symptom ³. NIDDK says creams, ointments, or suppositories may relieve mild pain, swelling, and itching, including of external hemorrhoids, for about a week ¹. MedlinePlus describes internal hemorrhoids as the ones that bleed during bowel movements, and external ones as the ones that make cleaning difficult and hurt if a clot forms ¹¹.

The best direct comparison of an ointment and a suppository is old, open-label, and not a test of the products on this page. In 1988, 89 people in general practice with second-degree hemorrhoids were assigned to one of two prescription steroid-and-antibiotic products, each in an ointment and a suppository. All four groups improved. Symptom control showed up from week 2 and was above 90 percent by week 3. Suppositories gave slightly more relief of pain and itching early on. Bleeding fell similarly with ointment and suppository. No side effects were blamed on treatment. There was no placebo arm, so the study cannot tell you how much was the medicine and how much was time ⁴.

A 2019 review of hemorrhoid research is more cautious. Apart from fiber, medical therapies have not been formally studied, and fiber results themselves have been inconsistent across papers ⁶. Family physicians still start with fiber, fluids, topical products, and sitz baths ⁷. Read what the studies say about over-the-counter treatment before you treat a suppository as a cure for bleeding.

Fiber is the part with a meta-analysis. Seven trials, 378 people: the risk of bleeding was about half in the fiber group (relative risk 0.50), and the risk that symptoms would not improve fell by 47 percent ¹⁷. In pregnancy, a large comparison gave everyone a glycerin suppository as a lubricant before bowel movements, plus daily psyllium. The groups differed in sitz baths versus a cream, not in whether a suppository was used. Healing was common in both ⁵. A Cochrane review found diet changes and local treatments in pregnancy have not been well tested in randomized trials ¹⁹.

Hydrocortisone suppositories have a clear limit even though our two boxes are not automatically that drug. The NHS how-to page says not to use hydrocortisone treatments for piles for more than 7 days, and to see a doctor if you are no better or symptoms return quickly ². The same page says they can be used morning, at night, and after a bowel movement. Follow the leaflet in your box if the schedule differs.

The cold pack has a different evidence trail. In a lab study, cold water did not lower resting pressure in the anal canal, while warm water did ⁹. Warm water also lowered pressure in people with hemorrhoids in a separate bath study, with the effect lasting after they got out ¹⁸. So a cold pack is not “doing what a sitz bath does.” It is for the swelling and throbbing people feel on the outside. The NHS piles page suggests an ice pack wrapped in a towel for discomfort ¹⁰. After hemorrhoid surgery, a 2025 trial of 166 people found ice packing lowered pain more than warm sitz baths in the first 16 hours, with less swelling at 24 hours and less morphine in the first day ⁸. That is surgical pain. It supports a short cold session. It does not mean ice replaces a suppository for internal swelling. Ice or heat for hemorrhoids and the ice pack guide go further.

Pregnancy: the NHS page on hydrocortisone suppositories in pregnancy says they can be used then, because little of the medicine reaches the blood, and for a short time while breastfeeding if you wash your hands first ¹⁵. A study of 204 women who used a hydrocortisone-and-numbing foam in the third trimester found no rise in prematurity or birth complications ¹⁴. Everyday products have not each been tested in pregnancy ¹³. Ask your obstetric provider before a medicated suppository. Hemorrhoids during pregnancy covers safer first steps, including fiber.

How to choose

Outside burning belongs on the best hemorrhoid creams. If you want an ointment that is labeled for both inside and outside, that comparison is on hemorrhoid ointments. Bleeding with bowel movements still needs fiber even if a suppository makes the evening more comfortable. The fiber guide and bleeding hemorrhoids are the pages for that symptom.

How to use them safely

These steps are the ones the NHS gives for hydrocortisone suppositories. Use them as the pattern, and follow your own leaflet if it disagrees ².

1. Go to the toilet first if you need to. A suppository that goes in just before a bowel movement often comes straight back out.
2. Wash your hands. Clean around the anus with mild soap and water, rinse, and pat dry.
3. Unwrap the suppository. If the foil will not tear, use scissors so you do not crush it. Throw away a piece that is cracked, crumbly, or melted into the wrapper.
4. Lie on your side with one knee bent, or stand with one foot on a chair. The pointed end goes in first, about 2 to 3 centimeters (about an inch).
5. Stay still for about 15 minutes so it can melt.
6. Wash your hands again.
7. For a hydrocortisone suppository, stop at 7 days ². NIDDK’s usual limit for over-the-counter hemorrhoid products is about a week. Call if symptoms are the same, or if you get a rash or very dry skin ¹.
8. Store Calmol somewhere cool. Do not leave either box in a hot car.

For the Hemorrwedge pack, freeze one while you use the other. Wrap it or set it on a thin cloth. Buyers get about 15 to 20 minutes of cold. Hard seams can dig in, so shift it if a edge pokes. Some packs split at the seam after months of use. Do not fall asleep with a bare pack against the skin. The NHS version of this advice is an ice pack wrapped in a towel ¹⁰.

While breastfeeding, keep any hydrocortisone suppository to a short course and wash your hands before you hold the baby ¹⁵. If feeding changes, call your clinician.

When to see a doctor instead

A suppository will not explain dark blood, a change in bowel habits, or weight loss. The American Cancer Society’s page on colorectal cancer symptoms lists blood that makes stool look dark brown or black, a bowel change lasting more than a few days, belly pain, weakness, and unintended weight loss ¹⁶. The US Preventive Services Task Force recommends screening from age 45 for adults at average risk ¹².

Get care right away for severe anal pain and rectal bleeding, particularly with belly discomfort, diarrhea, or fever ¹. Bright red bleeding can still be an internal hemorrhoid, and it still deserves a look if it is new. When to see a doctor for hemorrhoids describes the visit. If a week of a suppository plus fiber has not changed the bleeding, the next step is an exam, and sometimes banding, which the treatment overview explains.
