Heparinoid in skin creams and gels is used to relieve superficial bruising, haematomas and inflammation of superficial veins. It has local effects on inflammation and swelling. It is not equivalent to injected heparin and does not replace treatment for deep vein thrombosis or pulmonary embolism.
Apply gently to intact skin in the amount and frequency stated in the leaflet. Avoid vigorous massage over a painful vein. Do not apply to open wounds, mucous membranes, sensitive areas or large surfaces. Wash hands afterwards and avoid eye contact. Follow the product's age limit rather than assuming every formulation is suitable for children.
Local sensitisation reactions, such as redness, itching or dermatitis, may occur. Some creams contain lanolin or preservatives that can cause allergy. Stop applying it if irritation increases. Unexplained or numerous bruises, particularly when taking anticoagulants, need assessment of their cause rather than topical treatment alone.
See a doctor if swelling enlarges, pain increases or symptoms fail to improve. Sudden painful swelling of one leg needs prompt assessment; associated breathlessness or chest pain is an emergency. During pregnancy, breastfeeding or use in children, check with a pharmacist that the chosen formulation is appropriate.
