So, if there were any worries about allergies, a Z-Pack was an obvious, nearly all-purpose choice. To be clear, nothing really happened to Z-Packs specifically, Dr. Vyas says. In fact, in many ways, the rise and fall of the Z-Pack is simply a reflection of the way our understanding of antibiotics as a whole has developed in the past decade. We now know so much more about which antibiotics are best used for which illnesses, how the overuse and misuse of antibiotics contributes to antibiotic resistance, and the what the optimal time course is for various antibiotics.
All of this resulted in Z-Packs becoming a bit less unique and less suited for some common illnesses. The first big factor in the waning of Z-Pack popularity was that our developing understanding of antibiotic resistance made doctors wary about handing out Z-Packs so frequently for seemingly every minor health issue that might have a bacterial cause.
The exact way that bacteria become resistant to a drug like azithromycin is complex, but Dr. Vijayan says the basic gist is that already-resistant bacteria exist in small numbers. When bacteria are resistant to a medication, doctors need to use a different antibiotic to treat the infection. At this point, research estimates that up to 98 percent of group A streptococcus the bacteria that causes strep throat are resistant to azithromycin worldwide, Dr.
Vijayan says. In the U. The data included nearly , patients who took a five-day course of azithromycin and about 1. There were 29 cardiovascular deaths among those taking azithromycin, 22 of which were sudden cardiac deaths, which was estimated to equal about 64 deaths for every million prescriptions.
Among the control participants, there were 41 cardiovascular deaths, 33 of which were sudden cardiac deaths. That amounted to 24 deaths for every million control periods. Although the study only showed a correlation between taking the medication and sudden cardiac deaths, not a causal relationship, it was enough for the FDA to release a warning , and for doctors to take another look at their prescribing habits around azithromycin.
Vyas says, including diarrhea and nausea. The way doctors think about prescribing all antibiotics—not just Z-Packs—has evolved since these medications were introducted. Many people, like me, grow up being told that they had some kind of a rash or other vaguely bad reaction after getting penicillin treatment as a baby, which is very possibly true.
What appears to be a severe cold or flu may be symptoms of bacterial infections such as pneumonia or bronchitis. This is part of the reason why a thorough diagnosis is so important. If a healthcare professional sees signs of a particularly strong pneumonia or bronchitis infection, they may recommend antibiotics.
Antibiotics such as azithromycin would be effective in these cases, since the underlying issue stems from bacteria. According to the U. National Library of Medicine , azithromycin, the active ingredient in Z pack, may also be helpful against other infectious diseases, including:. Treatment still depends on what bacteria are causing the underlying infection. This is why a thorough diagnosis is important in each case before a doctor can recommend antibiotics. There is no reason to take a Z pack to treat a cold.
The common cold is a viral infection, most often a rhinovirus. Viruses are not susceptible to antibiotics such as the Z pack.
Specific antivirals may target and kill viruses, but the Z pack is not one of them. Taking the Z pack will not help with a cold in any way. So, in general, there is not much that a person needs to do when fighting a cold, as the body will do the most work.
If symptoms become uncomfortable or interfere with daily life, over-the-counter drugs may help treat symptoms until the body can get rid itself of the underlying infection. Some drugs, such as acetaminophen Tylenol , target symptoms individually, which helps reduce fever and pain. Other drugs, such as cough syrups, may contain different medicines to treat many symptoms at once. Always follow the instructions on the label and avoid using these drugs in children.
The common cold tends to go away on its own, as the body deals with the underlying viral infection. There are still steps a person can take to help prevent the cold or prevent the spread of the cold. Most common illnesses, such as the cold and flu, do not generally require antibiotics.
The viruses will not respond to antibiotics at all, so using them is unnecessary unless a bacterial infection is present. There is no reason to take a Z pack to treat the cold.
Anyone with concerns about their health during cold and flu season may want to consider discussing their options with a healthcare professional and taking measures to protect themselves from airborne viruses. Despite the association between cold weather and getting sick, it is viruses that cause colds and the flu.

You should also let your doctor know if you're taking any medicines for an irregular heartbeat arrhythmia , such as amiodarone or sotalol. Azithromycin can sometimes affect your heartbeat, so it's best not to take it with other medicines that have the same side effect.

Macrolide antibiotics work by killing the bacteria that cause the infection. There are other macrolide antibiotics that work in the same way as azithromycin.
They include erythromycin and clarithromycin. It's usual to take azithromycin once a day. For erythromycin, it's usually 4 times a day, and twice a day for clarithromycin. Erythromycin is more likely to cause diarrhoea than either azithromycin or clarithromycin. All macrolides can be used to treat chest and skin infections.
Azithromycin and erythromycin can also be used to treat sexually transmitted infections. Clarithromycin can also be used to treat Helicobacter pylori, bacteria that can cause stomach ulcers. Azithromycin and other macrolide antibiotics kill similar types of bacteria to penicillin antibiotics, such as amoxicillin. Some people are allergic to penicillin antibiotics - they can take macrolides like azithromycin instead. It's very important that you keep taking azithromycin until your course is finished.
Do this even if you feel better. It'll help stop the infection coming back. Tell your doctor if you don't start feeling better after taking azithromycin for 3 days. Also tell them if, at any time, you start to feel worse. Some people get a fungal infection called thrush after taking a course of antibiotics like azithromycin.
Antibiotics kill the normal harmless bacteria that help to protect you against thrush. Symptoms of thrush in the mouth include redness and itching. Women may get vaginal itching. Azithromycin doesn't stop contraceptive pills, including the combined pill and emergency contraception.
