Heparinoid

1. Introduction

Heparinoid is a topical anticoagulant and anti-inflammatory agent used to treat skin conditions associated with bruising, swelling, and superficial thrombophlebitis. It works by mimicking heparin, reducing blood clot formation, improving blood flow, and alleviating inflammation.

2. Indications

  • Approved Indications:
    • Superficial thrombophlebitis.
    • Haematoma (bruising).
    • Oedema and inflammation associated with soft tissue injuries (e.g., sprains, strains).
    • Localised pain and swelling from varicose veins.
  • Off-Label Uses:
    • Minor skin inflammation due to insect bites or stings.

3. Dosage

  • Topical Application:
    • Adults and children over 5 years: Apply 2–4 cm of cream or gel to the affected area 2–4 times daily.
    • Gently massage into the skin.
    • For thrombophlebitis, apply a thin layer without massaging.

4. Administration

  • Clean and dry the affected area before application.
  • Apply a thin layer of the cream/gel and gently massage unless otherwise directed.
  • Do not apply to open wounds, broken skin, or mucous membranes.
  • Avoid use near the eyes or mouth.

5. Forms Available

  • Cream: 0.3% heparinoid.
  • Gel: 0.3% heparinoid.

6. Side Effects

6.1. Common Side Effects

  • Skin irritation (e.g., redness, itching, burning).

6.2. Less Common Side Effects

  • Mild allergic reactions (e.g., rash).

6.3. Rare but Serious Side Effects

  • Severe allergic reactions (e.g., swelling, difficulty breathing).

7. Warnings

  • Skin Sensitivity: Avoid use on broken or infected skin.
  • Bleeding Risk: Although rare, there is a theoretical risk of increased bleeding if used on areas with active bleeding or in patients with clotting disorders.

8. Precautions

  • Avoid prolonged use unless directed by a healthcare provider.
  • Use cautiously in patients with known hypersensitivity to heparin or related compounds.
  • Do not use if the skin is infected or severely damaged.

9. Interactions

  • Drug-Drug Interactions:
    • Anticoagulants (e.g., warfarin, heparin): Increased risk of bleeding, though systemic absorption of heparinoid is minimal.
  • Drug-Food Interactions:
    • No significant interactions.

10. Monitoring Parameters

  • Relief of symptoms such as swelling, bruising, or inflammation.
  • Signs of skin irritation or allergic reactions.

11. Use in Children

  • Safe for children aged 5 years and older. Use under medical supervision for younger children.

12. Use in Pregnancy

  • Category C: Use only if the benefits outweigh the risks. Limited systemic absorption reduces the risk, but consult a doctor before use.

13. Use in Elderly

  • Safe for use in elderly patients, but monitor for skin sensitivity or irritation.

14. Use in Kidney Disease

  • Safe, as systemic absorption is minimal.

15. Use in Liver Disease

  • Safe, as systemic absorption is minimal and hepatic metabolism is not involved.

16. Patient Counselling Points

  • Apply heparinoid cream/gel as directed, avoiding broken or infected skin.
  • Gently massage the cream into the skin unless instructed otherwise (e.g., in thrombophlebitis).
  • Wash hands thoroughly after application.
  • Report any signs of skin irritation or unusual symptoms to your doctor.
  • Do not use near the eyes, mouth, or on mucous membranes.
