Get emergency medical help if you have signs of an allergic reaction: nausea, vomiting, sweating, hives, itching, trouble breathing, swelling of your face, lips, tongue, or throat, or feeling like you might pass out.

Heparin flush can cause bleeding. Call your doctor at once if you have easy bruising or unusual bleeding, such as a nosebleed, black or bloody tarry stools, or any bleeding that will not stop.

Stop using heparin flush and call your doctor at once if you have:

  • signs of a stroke--sudden numbness or weakness (especially on one side of the body), sudden severe headache, slurred speech, problems with vision or balance;
  • signs of a blood clot in the lung--chest pain, sudden cough, wheezing, rapid breathing, coughing up blood;
  • signs of a blood clot in your leg--pain, swelling, warmth, or redness in one or both legs;
  • a light-headed feeling, like you might pass out;
  • skin changes in your arms, legs, hands, or feet; or
  • (in an infant) extreme drowsiness, weakness, or gasping for breath.

Less serious side effects are more likely, and you may have none at all.

SIDE EFFECTS

Hemorrhage

Hemorrhage is the chief complication that may result from heparin. An overly prolonged clotting time or minor bleeding during therapy can usually be controlled by withdrawing the drug (see OVERDOSAGE).

Hypersensitivity

Generalized hypersensitivity reactions have been reported, with chills, fever, and urticaria as the most usual manifestations, and asthma, rhinitis, lacrimation, headache, nausea and vomiting, and anaphylactoid reactions, including shock, occurring more rarely. Itching and burning, especially on the plantar side of the feet, may occur.

Thrombocytopenia has been reported to occur in patients receiving heparin with a reported incidence of 0% to 30%. While often mild and of no obvious clinical significance, such thrombocytopenia can be accompanied by severe thromboembolic complications such as skin necrosis, gangrene of the extremities that may lead to amputation, myocardial infarction, pulmonary embolism, stroke, and possibly death. (See WARNINGS and PRECAUTIONS.)

Certain episodes of painful, ischemic, and cyanosed limbs have in the past been attributed to allergic vasospastic reactions. Whether these are in fact identical to the thrombocytopenia-associated complications remains to be determined.
