Hirudoid Gel

Hirudoid is indicated for the treatment of superficial thrombophlebitis and the soothing relief of superficial bruising and haematoma.

Adults, the elderly and children over 5 years of age:

Two to six inches (5-15 cm) to be applied, as a thin layer, up to four times a day to the affected area. Recommended when its cooling effect and rapid action are required.

Not to be used on large areas of skin, broken skin, sensitive areas of skin or mucous membranes. Not to be used in individuals with a known sensitivity to any active or inactive component of the formulation. Not to be used in children under 5 years of age.

For external use only. If symptoms persist or worsen, seek medical advice. Do not exceed the stated dose.

Instruct patients not to smoke or go near naked flames – risk of severe burns. Fabric (clothing, bedding, dressings etc) that has been in contact with this product burns more easily and is a serious fire hazard. Washing clothing and bedding may reduce product build-up but not totally remove it.

Reporting of suspected adverse reactions

Reporting suspected adverse reactions after authorisation of the medicinal product is important. It allows continued monitoring of the benefit/risk balance of the medicinal product. Healthcare professionals are asked to report any suspected adverse reactions via the Yellow Card Scheme at www.mhra.gov.uk/yellowcard or search for 'MHRA Yellow Card' in the Google Play or Apple App Store.

In the absence of any reports of the accidental ingestion of Hirudoid, no specific advice is available. General supportive measures may be appropriate.

Heparinoid is recognised as having: a weak inhibitory effect on PGE₂ synthesis and an indirect effect on LTB₄ production (based on in vitro studies), anti-coagulant activity (as a heparinoid), thrombolytic activity (through potentiation of urokinase activity), anti-exudatory activity (through inhibition of hyaluronidase).

Radiochemical studies of absorption following cutaneous application of heparinoid (mucopolysaccharide polysulphate) have shown that between 0.3 and 4% of the mucopolysaccharide administered is absorbed by various tissues (other than the treated area) within the first 8 hours. Typically between 1.7% and 4.6% will be absorbed within 2 to 4 days. Animal studies have also shown that mucopolysaccharide is bound intracellularly within the subcutis. Peak serum concentrations following cutaneous application are below the threshold of physiological relevance for coagulation. Mucopolysaccharide is excreted in the urine partly unchanged and partly as depolymerized, shorter chain length molecules.
