Precautions

Drug information provided by: Merative, Micromedex®

It is very important that your doctor check your progress at regular visits to make sure this medicine is working properly. Blood tests will be needed to check for unwanted effects. Be sure to keep all appointments.

This medicine may cause a serious type of allergic reaction called anaphylaxis. Anaphylaxis can be life-threatening and requires immediate medical attention. Tell your doctor right away if you have a rash; itching; swelling of the face, tongue, and throat; trouble breathing; or chest pain after you receive this medicine.

Make sure your doctor knows if you have had an allergic reaction to heparin, sulfites, benzyl alcohol, or pork products.

Tinzaparin may increase your chance of bleeding or bruising. This risk is higher if you have a catheter in your back for pain medicine or anesthesia (sometimes called an "epidural"), or if you have kidney problems. The risk of bleeding increases as the severity of your kidney problems increases. Check with your doctor right away if you notice any unusual bleeding or bruising; black, tarry stools; bleeding gums; blood in the urine or stools; or pinpoint red spots on your skin.

You may bleed and bruise more easily while you are using this medicine. Stay away from rough sports or other situations where you could be bruised, cut, or injured. Be careful when using sharp objects, including razors and fingernail clippers. Avoid nose picking and forceful nose blowing.

Be careful when using a regular toothbrush, dental floss, or toothpick. Your medical doctor, dentist, or nurse may recommend other ways to clean your teeth and gums. Check with your medical doctor before having any dental work done.

Make sure any doctor or dentist who treats you knows that you are using this medicine. You may need to stop using tinzaparin several days before having surgery or medical tests.

This medicine contains benzyl alcohol which may cause serious reactions to newborn or premature infants. Discuss this with your doctor if you are concerned.

Do not take or discontinue other medicines unless they have been discussed with your doctor. This includes prescription or nonprescription (over-the-counter [OTC]) medicines, and herbal or vitamin supplements.
