<p>If any circulatory disorder (like- myocardial infarction, deep venous thrombosis, pulmonary embolism, cerebrovascular injury etc) or other risk factors(like smoking, obesity, hypertension, dyslipidemia, migraine, atrial fibrillation etc) are present, the benefits of COC use should be weighed against the possible risks for each individual woman and discussed with the woman before she decides to start using it. In the event of aggravation, exacerbation or first appearance of any of these conditions or risk factors after taking pill, the woman should contact with her physician. The physician should then decide on whether its use should be discontinued.</p>
