Azithromycin is one of the most commonly prescribed antibiotics on the market. Millions of doses have been administered to patients dealing with bacterial infections such as bronchitis and pneumonia, as well as infections of the ears, lungs, and other organs. In the past couple of years, the drug has come under some scrutiny. The Food and Drug Administration announced in 2013 that azithromycin can cause a potentially fatal disturbance in a person’s heart rhythm. These two points are very important to remember: In patients with heart disease, though, azithromycin and other macrolide antibiotics – such as clarithromycin, erythromycin, and telithromycin – can speed up the heart so that it beats very fast, up to 200 times per minute. When the heart is beating that fast, its pumping action is greatly diminished – it can’t take in blood and pump it out correctly. As a result, blood pressure drops and a loss of consciousness becomes a risk. If a person experiences these symptoms while driving, a crash could easily happen. Worse still, if the condition isn’t treated, the heart could stop pumping altogether. Without rapid treatment – for example, applying an electrical impulse with a defibrillator – the patient could die. kamagra jelly This content has not been reviewed within the past year and may not represent Web MD's most up-to-date information.

" May 16, 2012 -- Sudden heart death may be a new risk from the commonly prescribed antibiotic azithromycin -- better known as Zithromax or the Z-Pak.

Compared to patients who took no antibiotics, those taking the five-day course of azithromycin treatment had about a threefold higher risk of heart death. Compared to patients with infections treated with amoxicillin, another antibiotic, those taking azithromycin had twice the risk of heart death. For every million courses of azithromycin treatment there were an estimated 47 extra heart deaths. Among people at highest risk of heart disease, there were 245 extra heart deaths per million courses of azithromycin.

The study results pointed to an increased risk among patients with a history of cardiovascular disease, and no significant differences were observed in comparison with patients who did not have that history. This was a retrospective study involving Danish adults ages 18-64, linking registry data on filled prescriptions, causes of death and medical histories for the period 1997-2010. The investigators estimated rate ratios for death from cardiovascular causes, comparing 1,102,050 episodes of azithromycin use with no use of antibiotic agents and comparing 1,102,419 episodes of azithromycin use with 7,364,292 episodes of use of penicillin V, an antibiotic with similar indications. The risk of death from cardiovascular causes was significantly increased with current use of azithromycin (defined as a 5-day treatment episode), as compared with no use of antibiotics. The analysis relative to an antibiotic comparator included 17 deaths from cardiovascular causes during azithromycin use (1.1 deaths per 1,000 person-years) and 146 during penicillin V use (1.5 deaths per 1,000 person-years). As compared with penicillin V, azithromycin was not associated with a significantly increased risk of cardiovascular death, indicating that the increased risk that was observed in comparison with no antibiotic use was attributable to the risk of death associated with acute infection.
