Limited clinical studies have demonstrated a moderate but statistically significant decrease in platelet aggregation and an increase in bleeding time in some nifedipine patients.
The flushing should go away after a few days, so try to carry on taking nifedipine for this time.
Blood pressure should be monitored and a reduction of the dose of nifedipine considered.
What is the dosage for nifedipine. To reduce dizziness and lightheadedness, get up slowly when rising from a sitting or lying position. If you are not sure a medicine is working, contact your doctor but continue to give the medicine as usual in the meantime. The findings appear to go beyond myocardial infarction, unstable angina, and stable angina. While the mechanism of this adverse effect is not known, there are several plausible explanations, including the established proischemic effect, negative inotropic effects, marked hypotension, recently reported prohemorrhagic effects attributed to antiplatelet and vasodilatory actions of calcium antagonists, and possibly proarrhythmic effects.
Older adults should discuss the risks and benefits of this medication with their doctor or pharmacist, as well as other possibly safer forms of nifedipine such as the long-acting tablets.

Chicken pox and measles, for example, can have a more serious or even fatal course in susceptible children or adults using corticosteroids.
You may need to stop using the medicine at least 36 hours before surgery. To view formulary information first create a list of plans. Controlled studies in small numbers of patients follow concomitant use of PROCARDIA and betablocking agents may be beneficial in patients with chronic stable angina, but available information is not sufficient to predict with confidence the effects of concurrent treatment, especially in patients with compromised left ventricular function or cardiac conduction abnormalities.
