Hirudoid Gel (Heparinoid Cream): Application, Indications, Contraindications, and Adverse Effects

Hirudoid cream (heparinoid-containing product) should be applied topically to the affected area up to 4 times daily, particularly for superficial thrombophlebitis and varicose vein symptoms, where it has demonstrated significant efficacy in reducing pain, swelling, and duration of symptoms. 1

Application Instructions

For external use:

• Cleanse the affected area by patting or blotting with an appropriate cleansing wipe before application 1
• Gently dry by patting or blotting with tissue or soft cloth 1
• Apply to the affected area up to 4 times daily, especially at night, in the morning, or after each bowel movement 1
• Regular use provides continual therapy for symptom relief 1

For intrarectal use:

• Remove cover from applicator and attach tube 1
• Lubricate applicator well, then gently insert into the rectum 1
• Thoroughly cleanse applicator after each use and replace cover 1
• Also apply ointment to external area 1

Primary Indications

Superficial vein thrombosis/thrombophlebitis:

• Hirudoid cream significantly shortens the duration of signs and symptoms including spontaneous pain, induced pain, edema, and limb heaviness 2, 3
• Provides effective local symptom control with topical analgesia 2

Varicose veins and venous insufficiency:

• Stabilizes symptoms and improves quality of life 4
• Enhances microcirculation in affected areas 5, 6

Hemorrhoidal conditions:

• Provides relief for symptomatic hemorrhoids when applied topically 3, 1
• One study showed heparin treatment significantly improved healing and resolution of acute hemorrhoids, though the evidence base is limited 3

Other approved uses:

• Post-operative varicophlebitis and sequelae of saphenectomy 6
• Traumas, contusions, local edemas, and infiltrates 6
• Subcutaneous hematomas 6
• Traumatic affections of musculotendinous and capsuloligamentous structures 6

Contraindications and Precautions

Absolute contraindications:

• Active bleeding at the application site 1
• Known hypersensitivity to heparinoid or other components 1

Ask a doctor before use if you have:

• Heart disease 1
• High blood pressure 1
• Thyroid disease 1
• Diabetes 1
• Trouble urinating due to prostate enlargement 1
• Currently taking prescription drugs for high blood pressure or depression 1

Special populations:

• Children under 12 years: ask a doctor before use 1
• Pregnancy or breastfeeding: ask a health professional before use 1

Important Safety Warnings

Stop use and consult a doctor if:

• Bleeding occurs at the application site 1
• Condition worsens or does not improve within 7 days 1
• Introduction of applicator into rectum causes additional pain 1

General precautions:

• For external and/or intrarectal use only 1
• Do not exceed recommended daily dosage unless directed by a doctor 1
• Keep out of reach of children 1
• If swallowed, get medical help or contact Poison Control Center immediately 1

Adverse Effects

Local skin reactions:

• Generally well tolerated with relatively low incidence of local skin events 5
• Potential for local irritation at application site 4
• Bruising may occur with topical application 3

Systemic effects:

• Minimal systemic absorption with topical use, reducing risk of bleeding complications compared to systemic heparin 6, 2
• No significant systemic anticoagulant effects reported with topical formulations 4, 5

Mechanism of Action and Clinical Effects

Pharmacological properties:

• Provides anticoagulation through anti-Xa and anti-IIa activity 4
• Enhances microcirculation in treated areas 4, 5
• Regulates skin permeability and improves epidermal barrier function 7
• Offers antithrombotic and anti-inflammatory actions through mucopolysaccharide polysulfate (MPS) content 4

Clinical efficacy:

• Moisture and gentle abrasion enhance heparin absorption through the skin 4
• Heparin gel 1000 IU/g formulations demonstrate superior efficacy compared to lower concentration preparations 5
• Accelerates permeability barrier recovery and increases stratum corneum hydration 7

Common Pitfalls to Avoid

• Do not use for more than 7 days without medical supervision for hemorrhoidal conditions, as prolonged use may cause complications 3
• Avoid assuming topical heparinoids are interchangeable with systemic anticoagulation—they serve different purposes 4, 6
• Do not apply to open wounds or areas with active infection without medical guidance 1
• Ensure proper cleansing and drying before application to maximize absorption and efficacy 1
