When your doctor prescribes erythromycin, a macrolide antibiotic used to treat bacterial infections like pneumonia, strep throat, and skin infections. Also known as Erythrocin, it works by stopping bacteria from growing, not killing them outright. It’s often chosen when someone can’t take penicillin, making it a go-to for many with allergies. But getting the erythromycin dosage right matters—too little won’t clear the infection, too much can cause serious stomach issues or even heart rhythm problems.
For adults, the typical dose ranges from 250 mg to 500 mg every 6 hours, or 333 mg every 8 hours, depending on how bad the infection is. Kids get doses based on weight—usually 30 to 50 mg per kilogram per day, split into multiple doses. It’s usually taken on an empty stomach, at least 1 hour before or 2 hours after meals, because food can mess with how well your body absorbs it. But if it upsets your stomach, taking it with a light snack is fine—just don’t go heavy on the fatty meals. You’ll often see it in tablet, capsule, or liquid form, and some versions are enteric-coated to protect your stomach lining.
It’s not just about the number of milligrams. Timing and duration matter too. Most courses last 7 to 14 days, even if you start feeling better after a few days. Stopping early is one of the biggest reasons bacteria become resistant. And don’t mix it with certain other drugs—like statins, some anti-anxiety meds, or even grapefruit juice. These can raise erythromycin levels in your blood and increase the risk of side effects like nausea, diarrhea, or rare but dangerous heart issues. If you’re on birth control, know that erythromycin might make it less effective, so use a backup method.
Some people take erythromycin for non-infectious reasons too, like treating acne or preventing infections before dental work. But it’s not a magic pill for every bug. If you’ve tried it before and it didn’t work, your infection might be resistant. That’s why doctors often switch to alternatives like azithromycin, doxycycline, or amoxicillin—depending on what’s causing the problem. Azithromycin, for example, is often taken once a day for just 3 to 5 days, which is easier to stick with. But erythromycin still has its place, especially for certain skin infections or when cost is a factor.
What you’ll find in the posts below isn’t just dosage charts. You’ll see real comparisons between erythromycin and other antibiotics, stories from people who had side effects, and what to watch for if you’re taking it long-term. There’s also info on how it interacts with other meds you might be using, and when it’s better to pick something else entirely. This isn’t theoretical advice—it’s based on what people actually experience and what studies show works in real life.
