1. What is innohep and what is it used for

Innohep is a medication that inhibits the natural ability of blood to form clots (coagulate).

Innohep is used to treat blood clots and prevent the formation of new clots in adults.

You should consult a doctor if your condition worsens or does not improve.

2. What you need to know before starting to use innohep

Do not use innohep

if you are allergic to tinzaparin sodium or any other component of this medication (listed in section 6).
if you have or have had heparin-induced thrombocytopenia.
if you have a severe bleeding disorder (e.g., in the brain, spinal cord, eyes, or stomach).
if you have a severe infection in the heart (septic endocarditis).
if you are scheduled for spinal or epidural anesthesia or a lumbar puncture.

Warnings and precautions

Consult your doctor or nurse before starting to use innohep

if you know you have a tendency to bleed.
if you are being treated with other medications by intramuscular injection.
if you have a low platelet count in your blood.
if you have high potassium levels in your blood (hyperkalemia).
if you have a prosthetic heart valve.
if you have kidney problems.

Children and adolescents

Innohep is not indicated for use in children and adolescents.

Use of innohep with other medications

Tell your doctor or pharmacist if you are using, have recently used, or may need to use any other medication. Some medications may interact with the effect of innohep.

Tell your doctor if you are using any of the following medications, as you may bleed more easily:

Medications for the treatment of inflammation and pain, especially non-steroidal anti-inflammatory drugs (NSAIDs), such as acetylsalicylic acid.
Medications used to dissolve blood clots (thrombolytic agents).
Medications that block the action of vitamin K (vitamin K antagonists).
Activated protein C.
Direct inhibitors of factor Xa and IIa.

Pregnancy and breastfeeding

If you are pregnant or breastfeeding, think you may be pregnant, or plan to become pregnant, consult your doctor or pharmacist before using this medication.

Innohep in pre-filled syringes can be used during all trimesters of pregnancy.

If epidural anesthesia is necessary, you should inform your doctor that you are using innohep.

Tell your doctor or nurse if you have a prosthetic heart valve.

Driving and using machines

Innohep does not affect your ability to drive or use machines.

Innohep contains sodium metabisulfite

As innohep contains sodium metabisulfite as an excipient, it may rarely cause severe allergic reactions and bronchospasm.
This medication contains 40 mg of sodium (the main component of table salt/cooking salt) per ml. This is equivalent to 2% of the maximum recommended daily intake of sodium for an adult.

3. How to use innohep

Follow the administration instructions for this medication exactly as indicated by your doctor or nurse. If you are unsure, consult your doctor or nurse again.

During treatment, your doctor may request routine blood tests to assess the effect of innohep.

Innohep should be injected under the skin (subcutaneous injection). Administration by intramuscular injection of other medications should be avoided during treatment with innohep, due to the risk of hematoma formation.

The recommended dose is:

175 IU anti-Xa per kg of body weight administered once a day.

Your doctor will indicate the appropriate dose for you.

Treatment should be administered once a day for 6 days, and may be extended up to 6 months. The need to extend treatment beyond 6 months should be evaluated by your doctor. Your doctor will indicate the duration of your treatment.

Instructions on how to inject innohep:

Wash your hands carefully before injecting this medication. Clean the skin around the injection site with an alcohol swab and let it dry without rubbing.

Hands holding an injection device with a needle, arrow indicates direction of insertion

Open the syringe container by lifting the colored cap all the way back, and remove the syringe.

Inspect the contents of the syringe before use. If you notice turbidity or a precipitate in the medication, do not use it and take another syringe. The medication may have a yellowish color during storage, but it can be used as long as the solution is clear and the expiration date has not been exceeded. Each syringe can only be used once.

Hand holding a syringe with a needle inserted into the skin, another hand guiding the syringe for subcutaneous injection

Fold the safety device down, separating it from the needle protector.

Two hands holding a syringe with an exposed needle and a partially retracted black safety device

Remove the cap that protects the needle without twisting it. Adjust the syringe contents to the prescribed dose by your doctor. Eliminate any excess volume by pressing the plunger in a vertical position. Do not pull the plunger back or eliminate the air bubble contained in the syringe. If the air bubble is not correctly positioned next to the plunger, gently tap the syringe until the air bubble is in place.

Hand holding a syringe with a needle inserted into the skin of the arm, another hand holding and tensing the injection site

Take a skin fold, without pressing, between the thumb and index finger of one hand, and with the other hand, insert the needle vertically and slowly into the skin fold, at a right angle to the skin.

Slowly inject the necessary dose into the fatty tissue, for example, the skin of the abdominal area, the front of the thighs, the lower back, or the back of the arms. Wait a few seconds to allow the solution to distribute before removing the needle and releasing the skin fold.

Clean the area with a gauze if you have bled. Choose a different injection site for the next time (e.g., alternating between the left and right side of the abdomen).

Hand holding an auto-injector with the needle inserted into the skin and an arrow indicating the direction of movement

Hand turning an auto-injector with the needle inserted into the skin, showing the direction of rotation

Fold the safety device back to its original position so that it is parallel to the needle. Then, with the safety device flat on a rigid surface, press down until the needle is locked into the device.

Hand holding a syringe with a needle inserted into the skin, arrow indicates direction of withdrawal, subcutaneous injection technique

The used syringe, with the needle facing down, can be inserted into the same syringe container or a container for sharp waste. In this way, the syringe is safe, and the container with the syringe or the container for sharp waste can be returned to a hospital or pharmacist for destruction.

If you use more innohep than you should

If you are treated with more innohep than you need, you may experience bleeding. Consult your doctor or nurse immediately if you do not feel well or think you have been given too high a dose of innohep.

If you forget to use innohep

Do not inject a double dose to make up for the forgotten dose. If you have forgotten to administer more than one dose, consult your doctor as soon as possible.

If you stop treatment with innohep

If you stop taking innohep, the effect of making your blood more fluid will cease. Do not stop treatment with innohep without consulting your doctor or nurse.

If you have any other questions about the use of this medication, ask your doctor or nurse.
