Anucort-HC Side Effects: What to Expect and When to Call Your Doctor

Starting a new rectal medication can feel uncomfortable in more ways than one. If you've been prescribed Anucort-HC (hydrocortisone acetate 25 mg rectal suppository) for hemorrhoids, proctitis, or another anorectal condition, knowing what side effects to expect — and which ones require immediate attention — can help you use this medication safely and confidently.

How Does Anucort-HC Work in the Body?

Anucort-HC delivers hydrocortisone acetate directly to the rectal tissue through a suppository. About 26% of the medication is absorbed into the bloodstream when applied rectally. This means most of its action is local — directly reducing inflammation in the rectal lining — but some systemic exposure does occur, especially with higher doses or prolonged use.

Common Side Effects of Anucort-HC

The most commonly reported local side effects of hydrocortisone acetate suppositories include:

Burning and itching: A mild burning or itching sensation during or after insertion is the most common complaint. This often improves as the rectal inflammation subsides with treatment.

Irritation: General rectal irritation, discomfort, or a sense of pressure is occasionally reported, especially in the first few days of use.

Dryness: Some patients notice dryness or a change in the texture of the rectal or anal tissue. This is typically minor.

Staining of clothing or fabrics: The hydrogenated vegetable oil base of the suppository can stain underwear or bed linens. Using disposable underwear or protective pads during treatment is recommended by some pharmacists.

Folliculitis: Inflammation of hair follicles in the perianal area is an uncommon but reported local side effect.

Less Common Local Side Effects

Hypopigmentation: With prolonged use, some patients experience lightening of the skin around the anal area. This is a known effect of topical corticosteroids when used long-term.

Allergic contact dermatitis: Rarely, patients may develop a localized allergic reaction to hydrocortisone or inactive ingredients in the suppository base (including palm oil). Signs include worsening redness, swelling, or rash that appears after starting treatment.

Secondary infection: Corticosteroids can suppress local immune activity, creating conditions favorable for bacterial or fungal infections. If you develop new or worsening symptoms during treatment, alert your prescriber.

Serious Side Effects: When to Call Your Doctor Immediately

Serious side effects from Anucort-HC are uncommon but require prompt medical attention if they occur:

Rectal bleeding: Stop using Anucort-HC and call your doctor immediately if you notice rectal bleeding that is new or worsening. While minor spotting can occur with hemorrhoids, significant rectal bleeding may indicate a more serious condition requiring evaluation.

Signs of systemic steroid effects: With prolonged use, systemic absorption of hydrocortisone can suppress the adrenal glands. Signs include unusual fatigue, weakness, dizziness, or unexplained weight changes. Contact your doctor if these develop.

Signs of allergic reaction: Seek emergency medical help for hives, difficulty breathing, or swelling of the face, lips, tongue, or throat — signs of a severe allergic reaction to the drug.

Worsening infection: If you have a pre-existing rectal infection and it worsens during treatment, your prescriber may need to add an antifungal or antibacterial agent and potentially pause Anucort-HC.

Elevated blood sugar: Patients with diabetes should monitor blood glucose more closely during Anucort-HC use, as corticosteroids can increase blood sugar levels even with rectal administration.

Special Precautions

Pregnancy: Use during pregnancy should be limited to cases where clearly needed and should not be prolonged. Other forms of hydrocortisone given systemically may harm an unborn baby.

Alcohol: Limit alcohol intake while using Anucort-HC to reduce the risk of gastrointestinal effects from systemic steroid absorption.

Duration of use: Do not use Anucort-HC longer than prescribed. Long-term use increases the risk of HPA axis suppression, skin thinning, and secondary infections.

What If Side Effects Don't Improve?

If irritation, burning, or itching doesn't improve — or worsens — after starting Anucort-HC, discontinue use and contact your prescriber. There are several alternatives to Anucort-HC that may be better tolerated. Do not self-diagnose; rectal symptoms that don't improve with treatment may need further evaluation.
