Uses For heparin

Heparin is an anticoagulant. It is used to decrease the clotting ability of the blood and help prevent harmful clots from forming in the blood vessels. heparin is sometimes called a blood thinner, although it does not actually thin the blood. Heparin will not dissolve blood clots that have already formed, but it may prevent the clots from becoming larger and causing more serious problems.

Heparin is used to prevent or treat certain blood vessel, heart, and lung conditions. Heparin is also used to prevent blood clotting during open-heart surgery, bypass surgery, kidney dialysis, and blood transfusions. It is used in low doses to prevent the formation of blood clots in certain patients, especially those who must have certain types of surgery or who must remain in bed for a long time. Heparin may also be used to diagnose and treat a serious blood condition called disseminated intravascular coagulation.

Heparin is available only with your doctor's prescription.

Before Using heparin

In deciding to use a medicine, the risks of taking the medicine must be weighed against the good it will do. This is a decision you and your doctor will make. For heparin, the following should be considered:

Allergies

Tell your doctor if you have ever had any unusual or allergic reaction to heparin or any other medicines. Also tell your health care professional if you have any other types of allergies, such as to foods, dyes, preservatives, or animals. For non-prescription products, read the label or package ingredients carefully.

Pediatric

Appropriate studies performed to date have not demonstrated pediatric-specific problems that would limit the usefulness of heparin in children. However, because heparin contains benzyl alcohol, use in newborn babies is not recommended.

Geriatric

Appropriate studies performed to date have not demonstrated geriatric-specific problems that would limit the usefulness of heparin in the elderly. However, elderly patients are more likely to develop bleeding problems, which may require an adjustment of dosage in patients receiving heparin.

Proper Use of heparin

Heparin is usually given in a hospital setting by a nurse or other trained health professional. heparin is given through a needle placed into one of your veins or as a shot under your skin.

If you are using heparin at home, make sure your doctor has explained exactly how heparin is to be given. Your doctor will prescribe your exact dose and tell you how often it should be given.

To obtain the best results without causing serious bleeding, use heparin exactly as directed by your doctor. Be certain that you are using the right amount of heparin, and that you follow a schedule. Be especially careful that you do not use more of it, do not use it more often, and do not use it for a longer time than your doctor ordered.

Your doctor should check your progress at regular visits. A blood test must be taken on a regular basis to see how fast your blood is clotting. This helps your doctor decide on the proper amount of heparin you should be receiving each day.

Missed Dose

If you miss a dose of heparin, take it as soon as possible. However, if it is almost time for your next dose, skip the missed dose and go back to your regular dosing schedule. Do not double doses.

Doubling the dose may cause excessive bleeding. Instead, go back to your regular dosing schedule. It is best to keep a record of each dose as you use it to avoid mistakes. Be sure to give your doctor a record of any doses you miss. If you have any questions about this, check with your doctor.

Storage

Store the medicine in a closed container at room temperature, away from heat, moisture, and direct light. Keep from freezing.

Keep out of the reach of children.

Do not keep outdated medicine or medicine no longer needed.

Ask your healthcare professional how you should dispose of any medicine you do not use.

Precautions While Using heparin

It is very important that your doctor check you at regular visits after you leave the hospital for any problems or unwanted effects that may be caused by heparin. Be sure to keep all appointments.

Do not take aspirin while using heparin. Many nonprescription (over-the-counter [OTC]) medicines and some prescription medicines contain aspirin. Check the labels of all medicines you take. Also, do not take ibuprofen unless it has been ordered by your doctor. There are many other medicines that may change the way heparin works or increase the chance of bleeding if they are used together with heparin. It is best to check with your doctor before taking any other medicine while you are using heparin.

You may bleed and bruise more easily while you are using heparin. Stay away from rough sports or other situations where you could be bruised, cut, or injured. Tell your doctor about any falls, blows to the body or head, or other injuries, since serious bleeding may occur inside the body with heparin. Brush and floss your teeth gently. Be careful when using sharp objects, including razors and fingernail clippers. Avoid nose picking and forceful nose blowing.

Since many things can affect the way your body reacts to heparin, you should always watch for signs of unusual bleeding. Unusual bleeding may mean that your body is getting more heparin than it needs. Serious side effects can occur, even up to several weeks after you have stopped using heparin. Check with your doctor right away if you have any unusual side effects while you are using heparin and after you stop using it.

Tell all medical doctors and dentists that you are using heparin.

It is recommended that you carry an identification card stating that you are using heparin. If you have any questions about what kind of identification to carry, check with your doctor.
