You’re probably here because you’ve looked at a tube or box of Preparation H and thought, “What’s in this stuff?” That’s a reasonable question. Hemorrhoid symptoms can be uncomfortable, messy, and stressful, and the pharmacy shelf doesn’t always make things clearer.
This guide walks through what each ingredient actually does, which form makes sense for which symptom, and when an over-the-counter product stops being enough.
Decoding the Box: What Is Preparation H?
Preparation H is a brand line of over-the-counter hemorrhoid products sold in different forms, including creams, ointments, suppositories, wipes, and gels. The name on the box stays the same, but the product inside can serve a different purpose.
That difference matters because hemorrhoid symptoms don’t all come from the same problem. Some people mainly have itching. Others feel burning, tenderness, or a sense of pressure from swollen tissue. Some need a product that coats and protects irritated skin. Others need medicine placed inside the rectum because the irritation is internal.
The brand has also changed over time. Older formulations and different product versions have used different ingredients, so two people can both say they used Preparation H and still be talking about products that work in different ways.
One more thing worth noting: the box tells you more than the brand name does. The formulation, the active ingredients, and the label directions determine what kind of relief you’re likely to get, how long you should use it, and when an OTC option may no longer be enough.
The Active Ingredients in Preparation H, Explained
A Preparation H box can look simple until you compare two versions side by side and realize they do different jobs. One widely listed Maximum Strength rectal cream contains phenylephrine HCl 0.25%, pramoxine HCl 1%, glycerin 14.4%, and white petrolatum 15%, according to DailyMed. Each ingredient plays a different role.
Phenylephrine helps shrink swollen tissue Phenylephrine HCl 0.25% is a vasoconstrictor. It temporarily narrows blood vessels in the treated area, which can reduce swelling and the feeling of pressure. For many people, the most bothersome symptom is fullness or puffiness after a bowel movement. Phenylephrine is aimed at that part of the problem. It can make a flare feel less swollen for a while, but it does not remove the hemorrhoid or fix the underlying cause.
Pramoxine helps quiet pain and itching Pramoxine HCl 1% is a local anesthetic. It reduces discomfort by dulling how strongly nearby nerves send pain and itch signals. A product with pramoxine can feel helpful even when the area still looks irritated, because less nerve signal means less burning, less stinging, and less urge to keep focusing on the area.
Glycerin and petrolatum protect the surface Glycerin 14.4% and white petrolatum 15% serve as protectants. They coat the tissue and help reduce further irritation from friction, moisture, wiping, and stool contact. That protective role matters more than many people realize. Hemorrhoids often flare in skin that is already irritated, and a barrier ingredient can make bowel movements and cleanup less aggravating.
Some versions use hydrocortisone instead Some Preparation H products have used hydrocortisone 1% rather than the ingredient mix above. Hydrocortisone is a steroid that targets inflammation and itch, so it serves a different purpose from phenylephrine or pramoxine. Steroid-containing products also have stricter limits on how long they should be used, and persistent symptoms after a short trial are a sign that an OTC option may not be enough.
Cream vs. Ointment vs. Suppository: What’s the Difference?
The three forms that confuse people most are cream, ointment, and suppository. They are built to reach different areas and do slightly different jobs.
Creams spread more easily and feel lighter on the skin, making them a common choice for external itching, burning, or mild swelling. Ointments are thicker and oilier, tending to cling to irritated skin longer, which can help when the area feels rubbed raw after bowel movements or frequent wiping. Suppositories are for internal rectal use. They are meant to melt inside the anal canal so the ingredients can reach tissue that a cream or ointment on the outside may not reach well.
The main question is simple: are your symptoms mostly outside, mostly inside, or both? That answer helps you choose the form, and it also helps you recognize the limits of over-the-counter care.
Important Safety and Usage Notes
Over-the-counter doesn’t mean risk-free. Preparation H labeling includes precautions for people with hypertension, cardiovascular disease, diabetes, and thyroid disease, and it includes guidance related to pregnancy and nursing. These products are built for temporary symptom relief. They don’t fix constipation, prevent future flares, or diagnose the cause of rectal symptoms.
Standard guidance is to stop use and see a provider if symptoms don’t improve after about 7 days, if they get worse, or if rectal bleeding occurs.
When OTC Products Stop Being Enough
Some people use an OTC product for a few days, feel some relief, and then watch the symptoms return. That is usually the point where the box has done all it can do.
There are a few signs that a provider visit makes sense:
- Symptoms last longer than a week
- Pain is severe or different from a typical flare
- Bleeding occurs
- Symptoms keep coming back
- You are not sure whether you are treating a hemorrhoid, a fissure, or something else
That last point matters. Anal fissures, which are small tears in the skin near the anal opening, can cause sharp pain that can look a lot like hemorrhoid pain at first. They have a different underlying cause and respond better to different treatment. An OTC cream may quiet symptoms temporarily without addressing what is actually happening.
What Prescription-Grade Compounded Treatment Does Differently
When OTC products fall short, it is usually because they are designed for symptom relief, not for treating the underlying physiology driving the problem.
Hemorrhoid pain and anal fissure pain are often rooted in two things: internal anal sphincter hypertonicity and local inflammation. Put plainly, the muscle around the anal canal goes into a kind of protective spasm in response to pain, which cuts off blood flow to the area and makes it harder for tissue to heal. Breaking that cycle is what prescription-grade topical treatment is designed to do.
Bummed uses compounded topical formulations built around ingredients with established clinical evidence for anorectal conditions. Here is what each one does.
Nitroglycerin increases nitric oxide availability, which relaxes the internal anal sphincter and improves blood flow to the tissue. Randomized trials show improved healing for chronic anal fissure compared to placebo. It also helps relieve pain-induced sphincter spasm in hemorrhoid flares, which can speed resolution. Some patients experience headaches at higher doses, which is why formulation matters.
Diltiazem is a calcium channel blocker that has demonstrated healing rates comparable to nitrates in systematic reviews, with a more favorable side effect profile. It is particularly useful for patients who have experienced headaches with nitroglycerin, or who need sustained sphincter relaxation over time.
Nifedipine is another calcium channel blocker with high healing rates in randomized trials and generally fewer headaches compared to nitrates. For patients who need durable sphincter relaxation with good tolerability, nifedipine is often a practical option.
Metronidazole is not a primary therapy for fissures or hemorrhoids, but randomized studies have shown it reduces postoperative pain following excisional hemorrhoidectomy. Its benefit appears to come from local anti-inflammatory effects and reduction in bacterial colonization of healing tissue. It is incorporated in formulations where inflammatory pain or complex anorectal irritation is part of the picture.
The reason these ingredients are compounded rather than sold off the shelf is that most patients don’t present with one clean diagnosis. A person may have hemorrhoidal congestion alongside a fissure, or postoperative inflammation alongside pelvic floor tension. Compounding allows providers to combine agents with complementary mechanisms and tailor the formulation to the actual clinical picture.
Bummed pairs topical treatment with a bowel regimen and patient education. The goal is not to skip procedural care when it’s needed. It is to treat pathology earlier, using mechanisms that are supported by clinical literature, and to make that level of care accessible without requiring a specialist visit.
If OTC products aren’t giving enough relief, Bummed offers discreet online care for hemorrhoids, fissures, and related anorectal symptoms, with provider review and prescription treatment when appropriate.
Frequently Asked Questions
What’s in Preparation H most commonly?
Many current OTC formulations combine phenylephrine HCl 0.25% and pramoxine HCl 1%. One widely listed cream also contains petrolatum 15% and glycerin 14.4%. Different products in the line may use different ingredients, so the specific product matters.
Does Preparation H cure hemorrhoids?
No. It is designed for temporary symptom relief. It can help with swelling, pain, itching, and tissue protection, but it does not address the underlying cause of chronic or recurring hemorrhoids.
How long should you use Preparation H before seeing a provider?
Use should be short term. Standard guidance is to stop and consult a provider if symptoms don’t improve within 7 days, worsen, or if rectal bleeding occurs.
What is a compounded hemorrhoid cream and how is it different?
A compounded cream is a prescription formulation mixed by a licensed pharmacy based on a provider’s order. Unlike OTC products, compounded creams can include prescription-grade ingredients like nitroglycerin, diltiazem, or nifedipine that target the underlying sphincter physiology driving anorectal pain, not just the surface symptoms.
What if symptoms keep coming back?
Recurring symptoms are a sign to look beyond temporary relief. The issue may still be hemorrhoids, but it may also be a fissure, a pattern of constipation and straining, or another condition that needs a more targeted treatment plan.
