Does Preparation H Actually Work? Honest Review (2026)

Last Updated: April 9, 2026 | Medically Reviewed by the HemRid Medical Team

Quick Answer: Preparation H provides temporary symptom relief through vasoconstriction and skin protectants, but it does not treat the underlying cause of hemorrhoids. Most users experience short-lived relief lasting 1-4 hours before symptoms return. For lasting results, you need to address hemorrhoid root causes with approaches that strengthen vein walls and reduce inflammation from the inside.

"Does Preparation H work?" is one of the most common questions hemorrhoid sufferers ask, and the answer is more nuanced than a simple yes or no. As the most recognized hemorrhoid brand in America, Preparation H has been on pharmacy shelves for decades. But brand recognition doesn't always equal effectiveness.

In this honest review, we break down exactly what's in Preparation H, what it can and can't do, its side effects, and why millions of users eventually look for alternatives.

What's Actually in Preparation H?

Preparation H comes in several formulations, and the ingredients vary significantly between them. Understanding what you're actually applying matters.

Preparation H Ointment (Original)

• Phenylephrine HCl (0.25%): A vasoconstrictor that temporarily shrinks swollen blood vessels
• Petrolatum (71.9%): A skin protectant that creates a moisture barrier
• Mineral oil (14%): Lubricant and skin softener
• Shark liver oil (3%): Contains squalene, marketed as a skin protectant and healing aid (note: some newer formulations have removed shark liver oil)

Preparation H Cream

• Phenylephrine HCl (0.25%): Same vasoconstrictor as the ointment
• Skin protectant base with various inactive ingredients

Preparation H Suppositories

• Phenylephrine HCl (0.25%): Vasoconstrictor
• Cocoa butter (85.5%): Skin protectant and suppository base

Preparation H with Lidocaine

• Lidocaine: Local anesthetic for pain relief
• This is actually the most effective Preparation H variant for pain, though dedicated lidocaine products like HemRid Lidocaine Cream often offer higher concentrations

What Preparation H Actually Does

Let's give credit where it's due. Preparation H does provide some real, measurable effects:

Temporary Vasoconstriction

Phenylephrine causes blood vessels to constrict, temporarily reducing the size of swollen hemorrhoid tissue. This can provide short-term relief from the "full" or "bulging" sensation of external hemorrhoids.

How effective: Clinical studies on topical phenylephrine for hemorrhoids specifically are limited. The vasoconstriction effect is real but modest and temporary, typically lasting 1-4 hours.

Skin Protection

The petrolatum and mineral oil in the ointment formulation create a physical barrier over irritated skin. This can:

• Reduce friction during movement
• Protect raw or irritated tissue from contact with stool
• Lock in moisture to prevent drying and cracking

How effective: As a protective barrier, Preparation H ointment performs reasonably well. This is genuinely helpful for reducing discomfort from friction and contact irritation.

Lubrication

The mineral oil and petrolatum provide lubrication that can make bowel movements less painful when hemorrhoids are present.

How effective: This is one of Preparation H's most practical benefits, especially for people experiencing pain during bowel movements.

What Preparation H Does NOT Do

This is where the honest review gets important. Despite its marketing and widespread use, Preparation H has significant limitations:

It Does Not Treat the Root Cause

Hemorrhoids are caused by weakened vein walls, poor venous circulation, chronic straining, and increased pressure in the rectal area. Preparation H addresses none of these underlying issues. It's the equivalent of putting a bandage on a wound without cleaning it first — it may cover the symptom, but the problem persists underneath.

It Does Not Strengthen Vein Walls

Unlike bioflavonoid supplements such as HemRid Max that contain clinically studied ingredients like diosmin and hesperidin to improve venous tone and wall strength, Preparation H has no vein-strengthening properties whatsoever.

It Does Not Reduce Hemorrhoid Grade

Preparation H cannot shrink hemorrhoids in any permanent sense. While it may temporarily reduce swelling through vasoconstriction, the hemorrhoid tissue returns to its swollen state once the effect wears off. It will not cause a Grade II or III hemorrhoid to regress.

It Does Not Prevent Recurrence

Because it doesn't address root causes, Preparation H does nothing to prevent hemorrhoids from coming back. Users often find themselves on a cycle of application, temporary relief, symptom return, and reapplication.

Preparation H Side Effects

While generally considered safe for short-term use, Preparation H can cause side effects that many users aren't aware of:

Common Side Effects

• Burning or stinging upon application: Particularly with the cream formulation, some users experience an initial burning sensation
• Skin irritation: Prolonged use can cause contact dermatitis in sensitive individuals
• Dryness or peeling: Some formulations can dry out the perianal skin with repeated use

Less Common but Important Side Effects

• Rebound swelling: This is a significant concern. With regular use of phenylephrine-based products, blood vessels can develop a rebound effect where they become MORE swollen when the product wears off, creating a dependency cycle
• Allergic reactions: Some users develop sensitivity to ingredients in the formulation over time
• Thinning of perianal skin: Long-term use of any topical hemorrhoid product can contribute to skin thinning in the delicate perianal area

The Steroid Versions

Preparation H also makes a hydrocortisone-based product (Preparation H Anti-Itch Cream). Hydrocortisone is a corticosteroid, and while effective for itch, it carries specific risks:

• Skin thinning (atrophy) with prolonged use
• Should not be used for more than 7 consecutive days without medical supervision
• Can mask symptoms of worsening conditions

Duration of Relief: What to Realistically Expect

Based on user reports and the pharmacology of the active ingredients, here's a realistic timeline of what Preparation H provides:

• 0-5 minutes: Application. Some users feel immediate soothing from the ointment barrier; others feel initial stinging.
• 5-30 minutes: Peak vasoconstriction effect begins. Modest reduction in swelling and the sensation of pressure.
• 30 minutes - 2 hours: Maximum relief window. This is when Preparation H is at its best.
• 2-4 hours: Effects begin to fade. Swelling gradually returns.
• 4+ hours: Most users report symptoms have returned to baseline.

For many hemorrhoid sufferers, this means reapplying 3-6 times per day to maintain any semblance of comfort, which raises concerns about the rebound effect mentioned above.

Why People Stop Using Preparation H

After decades of loyal customers, Preparation H has also accumulated a long list of people who moved on. Here are the most common reasons:

"It Stopped Working"

Many users report that Preparation H seemed effective initially but became less effective over time. This is consistent with the pharmacological concept of tolerance and the rebound effect of repeated vasoconstrictor use.

"Relief Didn't Last"

The short duration of action means constant reapplication, which is inconvenient and impractical for people with busy lives.

"My Hemorrhoids Kept Coming Back"

Because Preparation H doesn't address root causes, users who rely on it exclusively often experience a frustrating cycle of flare-ups. The hemorrhoids never truly get better; they just get temporarily masked.

"I Wanted Something That Actually Fixes the Problem"

As consumers become more educated about hemorrhoid treatments, many seek products that offer more than temporary symptom masking.

Alternatives That Address the Root Cause

If you're frustrated with the limitations of Preparation H, here are approaches that target hemorrhoids at their source:

Oral Bioflavonoid Supplements

HemRid Max contains clinically studied bioflavonoids (diosmin, hesperidin, horse chestnut extract) that work from the inside to strengthen vein walls, improve venous tone, and reduce the inflammation that causes hemorrhoids. A meta-analysis in the British Journal of Surgery found that oral flavonoid therapy reduced hemorrhoid bleeding by 67% and overall symptoms significantly compared to placebo.

Clinical-Strength Topical Relief

When you do need topical pain relief, a product like HemRid Lidocaine Cream with 5% lidocaine provides more potent and longer-lasting pain relief than the 0.25% phenylephrine in standard Preparation H.

Fiber Supplementation

Fiber Gummies address one of the most common hemorrhoid triggers: straining during bowel movements. Regular fiber supplementation softens stools, reduces straining, and has been shown in clinical research to reduce hemorrhoid symptoms by 47% and bleeding by 50%.

The Combination Approach

The most effective strategy combines: 1. Internal treatment (HemRid Max) for vein health 2. Topical treatment (HemRid Lidocaine Cream) for pain when needed 3. Preventive care (Fiber Gummies) to stop the straining cycle

Is Preparation H Worth Buying?

Here's our balanced assessment:

Preparation H may be worth it if:

• You need a quick, one-time solution for a very mild flare-up
• You specifically need a lubricating barrier for bowel movement comfort
• You're looking for something available at any pharmacy at midnight

Preparation H probably isn't worth it if:

• You have recurring hemorrhoids (it won't break the cycle)
• You need meaningful, lasting pain relief (the effects are too short-lived)
• You want to actually improve your hemorrhoid condition over time
• You're looking for the most effective pain relief per dollar

Frequently Asked Questions

Does Preparation H shrink hemorrhoids permanently? No. It can temporarily reduce swelling through vasoconstriction, but this effect wears off within hours. It does not cause permanent hemorrhoid shrinkage.

Can I use Preparation H every day? The label recommends use for up to 7 days. Extended daily use, particularly of the phenylephrine formulations, is not recommended due to rebound and tolerance concerns. Consult a doctor if symptoms persist beyond a week.

Is Preparation H safe during pregnancy? The phenylephrine in Preparation H is a vasoconstrictor, and pregnant women should consult their OB-GYN before using any medication containing vasoconstrictors. Many doctors recommend alternative approaches during pregnancy.

What works better than Preparation H? For pain: 5% lidocaine cream provides stronger, longer-lasting numbing. For treatment: oral bioflavonoid supplements address root causes. For prevention: fiber supplementation reduces straining. A combination of all three typically outperforms Preparation H significantly.

The Bottom Line

Preparation H is not a bad product — it's a limited one. It provides modest, temporary symptom relief through vasoconstriction and skin protection. But it doesn't treat the cause of hemorrhoids, doesn't prevent recurrence, and doesn't provide the level of pain relief that modern alternatives can achieve.

If you're tired of the cycle of apply, wait, reapply, and repeat, consider an approach that treats hemorrhoids from both the inside and outside. HemRid Max for internal vein support combined with HemRid Lidocaine Cream for external pain relief offers a more comprehensive solution that addresses what Preparation H cannot.
