Tegretol, whose trade name is Belinda, is currently only available as an international import without a domestic generic. Tegretol costs about$130-140 per box and is used for antiplatelet aggregation. Tegretol is mainly used for the treatment of patients with acute coronary syndromes, including unstable angina, ST-segment elevation myocardial infarction and non-ST-segment elevation myocardial infarction. Such patients belong to the acute and critical cardiology population. Patients should take two antiplatelet drugs under the guidance of a cardiologist, including aspirin combined with Polivir or aspirin combined with Tegretol. Tegretol is recommended instead of Polivir in most patients older than 75 years old or in patients with usual wheezing or bronchial asthma. Patients with bleeding from the mouth, nose, gums or bleeding spots all over the body after taking Tegretol indicate a bleeding tendency and should go to the hospital promptly to contact a cardiologist for further consultation; patients with frequent black stools or vomiting blood or vomiting blood are considered to have possible gastrointestinal hemorrhage and should be immediately transferred to a nearby qualified tertiary care hospital to receive further medical treatment in the emergency department or chest pain center or cardiology. If there is no medical advice to stop taking the medication, the patient should not stop taking the medication at will.
