How and when to use heparinoid - Brand: Hirudoid

If you have bought heparinoid from a pharmacy or shop, follow the instructions that come with the packet, or ask your pharmacist for advice.

Dosage and strength

There is 3mg of heparinoid in 1 gram of cream or gel.

Adults and children aged 5 years and over can use heparinoid cream or gel up to 4 times a day.

How to use heparinoid cream or gel

The amount of heparinoid cream or gel you use will depend on the size of the area you're treating.

  1. Squeeze out between 5cm and 15cm (2 inches to 6 inches) of cream or gel. Do not use any more than this at any one time.
  2. Gently massage into the affected area. If the skin you're treating is broken, sore or tender, massage the cream or gel into the skin around it. Do not use it on or near your mouth, eyes, bottom or genital areas.
  3. Wash your hands after using heparinoid cream or gel.

Important: Fire warning

Heparinoid skin creams can dry onto your clothes and bedding. This makes them more likely to catch fire. Avoid smoking and naked flames.

How long to use it for

Use heparinoid gel or cream until your symptoms have gone.

  • Bruises and haematomas usually go away within 1 to 2 weeks.
  • Superficial thrombophlebitis can take a few weeks to go away.

If your symptoms are no better after this time, talk to your doctor.

If you forget to use it

If you forget to use your heparinoid, apply it as soon as you remember. If you do not remember until you are within a few hours of the next treatment, skip the missed treatment and wait until the usual time.

If you use too much

If you accidentally use too much heparinoid, it's unlikely to cause any problems.

It's important to use heparinoid as described in the leaflet that comes in the packet, or as directed by your doctor or pharmacist.
