Why have I been prescribed Innohep?
- Innohep (Tinzaparin) belongs to a group of medicines called low molecular weight heparins which help to stop the blood from clotting.
- Innohep is used to treat blood clots in blood vessels, for example clots in the veins of the leg and clots in the blood vessels of the lung.
How does it work?
Innohep blocks the chemicals in the body that cause blood to clot.
When and how do I take it?
Innohep is administered by injection under the skin. It can either be administered by a health care professional or you may be taught how to inject yourself. It is usually given once a day for at least 6 days depending on your own response to the medicine.
Usually your doctor or nurse will give you instructions on how to use Innohep before you give yourself the first injection. Your doctor or nurse will tell you the volume to inject.
Remember you may not need to inject the entire contents of the syringe.
Instructions on injecting yourself with Innohep:
- 1) Wash your hands and the area that you will inject with soap and water. Dry them.
- 2) Sit or lie in a comfortable position so you are relaxed. Make sure you can see the place you are going to inject. A lounge chair, recliner, or bed propped up with pillows is ideal.
- 3) Choose an area on the right or left side of your stomach. This should be at least 5 centimetres away from your belly button and out towards your sides.
- Remember: Do not inject yourself within 5 centimetres of your belly button or around existing scars or bruises. Change the place where you inject between the left and right sides of your stomach, depending on the area you were last injected.
- 4) Carefully pull off the needle cap from the Innohep syringe. Throw away the cap. The syringe is pre-filled and ready to use. Do not press on the plunger before injecting yourself to get rid of air bubbles. This can lead to a loss of the medicine. Once you have removed the cap, do not allow the needle to touch anything. This is to make sure the needle stays clean (sterile).
- 5) Hold the syringe in the hand you write with (like a pencil) and with your other hand, gently pinch the cleaned area of your abdomen between your forefinger and thumb to make a fold in the skin. Make sure you hold the skin fold throughout the injection.
- 6) Hold the syringe so that the needle is pointing downwards (vertically at a 90º angle). Insert the full length of the needle into the skin fold.
- 7) Press down on the plunger with your finger. This will send the medication into the fatty tissue of the stomach. Make sure you hold the skin fold throughout the injection.
- 8) Remove the needle by pulling it straight out. You can now let go of the skin fold.
- To avoid bruising, do not rub the injection site after you have injected yourself.
- 9) Drop the used syringe into the sharps bin provided. Close the container lid tightly and place the container out of reach of children.
- When the container is full, give it to your doctor or home care nurse for disposal. Do not put it in the household rubbish.
