Macrolide antibiotics: what they are and when to use them
Macrolide antibiotics are a common group of drugs used to treat respiratory infections, certain skin infections, and some sexually transmitted infections. You’ve probably heard of azithromycin or erythromycin. These medicines stop bacteria from making proteins they need to grow, which helps your immune system clear the infection. But they aren’t magic — resistance and safety issues matter.
Common macrolide drugs & uses
Azithromycin (Z-pack) is the one most people know. It’s often used for bronchitis, sinus infections, and some ear infections. It’s popular because of short courses and easy dosing.
Clarithromycin is similar but hits a few different bugs and is often used for certain lung infections and stomach infections caused by H. pylori (when combined with other meds).
Erythromycin is older and causes more stomach upset, but doctors still use it for some infections and for newborns in specific cases. Your doctor picks one based on the bug, your allergies, and other meds you take.
Safety tips, side effects & interactions
Common side effects are nausea, diarrhea, and stomach cramps. If you get severe belly pain or yellowing of the skin, tell your doctor straight away. Macrolides can also affect heart rhythm in people with certain conditions — they can lengthen the QT interval. If you have heart issues or take drugs that also affect QT (some antidepressants, antipsychotics, or methadone), your doctor will be cautious.
Drug interactions matter. Clarithromycin and erythromycin inhibit the liver enzyme CYP3A4, which can raise levels of other drugs like some statins, certain blood thinners, and some anti-seizure meds. Azithromycin has fewer CYP interactions but still shares the QT concern. Always give your full med list to the prescriber.
Don’t stop early just because you feel better. Stopping antibiotics too soon can let bacteria survive and become resistant. If you miss a dose, take it as soon as you remember unless it’s close to the next dose — then skip and keep the schedule.
Pregnancy and kids: doctors often prefer erythromycin or azithromycin when an antibiotic is needed in pregnancy, but every case is different. Pediatric dosing follows weight — never guess doses for children. Ask a clinician or pharmacist if you’re unsure.
Thinking of buying antibiotics online? Use licensed pharmacies that require a prescription, show clear contact details, and have real pharmacist support. Avoid sites that sell antibiotics without a prescription or offer suspiciously low prices. Your health and safety depend on real oversight.
If symptoms get worse, you have a high fever, breathing problems, or severe side effects, seek medical care quickly. Macrolides can be very helpful when used right — but they must be matched to the infection and your personal risks.
