Z-Pac, Cardiovascular Risk and Medical Malpractice

When I get sick, I assume an antibiotic will solve my problems.  I’m slightly allergic to amoxicillin. Zithromax, Z-Pak (Z-Pac, I’ve seen both), Zmax, or any similar antibiotic to treat bacterial infections is my drug of choice for ear infections, strep throat, pneumonia, traveler’s diarrhea, or other intestinal infections.

There are risks with any drug. You have been told that time and time again. But if you are like me, you just want to feel better and you have a history with antibiotics of doing just that.

A new study underscores that maybe we should slow our roll in racing to get Zithromax.  Because the study suggests that the potential side effects are more than just theoretical and can increase the risk of heart problems and death.  This gets my attention. Because I’d rather be sick than dead.

Z-Pac

2023 Study

The study “Relationship Between Azithromycin and Cardiovascular Outcomes in Unvaccinated Patients With COVID-19 and Preexisting Cardiovascular Disease,” published in the Journal of the American Heart Association, investigated the cardiovascular risks associated with azithromycin in COVID-19 patients. Using data from the ISACS-COVID-19 registry, it included 793 patients treated with azithromycin and 2141 receiving standard care. The primary outcomes were 30-day mortality and acute heart failure (AHF).

Key findings revealed that among patients with preexisting cardiovascular disease (CVD), Z-Pac use was significantly associated with an increased risk of AHF (risk ratio [RR], 1.48) but not with an increased risk of death (RR, 0.94). Conversely, in patients without prior CVD, azithromycin was associated with a reduced risk of death (RR, 0.57) and no significant increase in acute heart failure. These findings suggest that while azithromycin may pose cardiovascular risks for patients with preexisting cardiovascular disease, it might offer some mortality benefit for those without prior cardiovascular conditions. What that tells us is that this is not always a simple decision and it needs to be make with your doctor. Getting educated online is not enough.

FDA Safety Communication

The FDA issued a Zithromax drug safety communication, warning that the drug can disrupt the electrical activity of the heart. Federal drug regulators also warned that the side effects of Zithromax can cause serious and potentially life-threatening abnormal heart activity.  Multiple medical journals have published reports warning of the potential Zithromax heart risks.

These reports found that patients were 2.5 times more likely to die due to heart-related problems on a five-day Zithromax treatment when they compared it to treatment with other antibiotics or no antibiotic therapy. Despite these reports, the drug has continued to be widely distributed across the country.  As I’m sure it should be.  Again, it is all about cost/benefit and talking to your doctor about whether the risks are worth it for you.  This is true with Z-Pak but it is also true with any other drug or treatment.

Malpractice Lawsuits for Overprescribing Z-Pac

The overuse and misuse of Z=Pac amplify the risks associated with their use. One of the most concerning consequences is the development of resistance to azithromycin. As bacteria are repeatedly exposed to the drug, they can adapt and become resistant, rendering the antibiotic less effective and making infections harder to treat.

Despite these risks, Zithromax remains a go-to antibiotic for many healthcare providers and patients. Its reputation for effectiveness and convenience often leads to its prescription even when alternative treatments may be more suitable. This over-reliance can unnecessarily expose patients to its potential side effects, including serious cardiovascular risks, when other antibiotics might carry fewer dangers.

Are there over-prescription of Z-Pac malpractice lawsuits.  There are.  But these suit are rare because, thankfully, the injuries are usually not serious enough to justify the expense of a medical malpractice lawsuit.

Special Populations at Risk

Certain groups of people face a heightened risk of adverse effects from Zithromax, making its use in these populations a careful balancing act between risks and benefits. Elderly patients, for example, are more susceptible to QT prolongation and other cardiac issues we discussed above due to age-related changes in heart function and the likelihood of concurrent medications that may interact with Zithromax. These factors can significantly increase the risk of arrhythmias, particularly in those with preexisting heart conditions.

For children, Zithromax is generally considered safe and effective for treating various bacterial infections. But careful dosing is critical. Pediatric patients, especially babies, are more vulnerable to certain side effects, and doctors must weigh the benefits of treatment against potential risks, such as gastrointestinal upset or allergic reactions.

Pregnant and breastfeeding women also present unique considerations. While Zithromax is classified as Category B by the FDA, meaning that animal studies have not shown harm to the fetus and limited human studies suggest it is generally safe. But some believe it is best to proceed with caution. The potential transfer of the drug through breast milk raises questions about its effects on nursing infants. Those concerns do not have strong scientific support.  But that does not mean there is no foundation for concern.

Lastly, individuals with compromised immune systems, such as those living with HIV or cancer, certainly can benefit from Z-Pac’s broad-spectrum activity against bacterial infections. The problem is that these patients are also at greater risk of side effects due to their weakened health and possible interactions with other medications. In these cases, health care providers need to keeps tabs on the patient to ensure the benefits of treatment outweigh the potential harms.
