Erythroped (Erythromycin) Suspension contains the active ingredient erythromycin, which is a type of medicine known as a macrolide antibiotic. It is used to treat infections caused by bacteria. Erythroped is a brand name for the active ingredient erythromycin.

What is Erythroped?

  • Erythroped is a brand name for Erythromycin, which is part of a group of drugs called macrolide antibiotics. Macrolide antibiotics slow the growth of, or sometimes kill, sensitive bacteria by reducing the production of important proteins needed by the bacteria to survive.
  • Erythroped is used to treat many different types of infections caused by bacteria.

How should I take Erythroped?

  • Take Erythroped exactly as prescribed by your doctor. Do not take in larger or smaller amounts or for longer than recommended. Follow the directions on your prescription label.
  • You may take Erythroped with or without food.
  • Do not crush, chew, break, or open an erythrocin tablet or capsule. Swallow it whole. Shake the oral suspension (liquid) well just before you measure a dose. Measure the liquid with a special dose-measuring spoon or medicine cup, not with a regular table spoon.
If you do not have a dose-measuring device, ask your pharmacist for one.
  • This medication can cause unusual results with certain medical tests. Tell any doctor who treats you that you are using Erythroped.
  • Take this medicine for the full prescribed length of time. Your symptoms may improve before the infection is completely cleared. Skipping doses may also increase your risk of further infection that is resistant to antibiotics. Erythroped will not treat a viral infection such as the common cold or flu.
  • Store Erythroped at room temperature away from moisture and heat, unless otherwise directed on the medicine label.
  • How does it work?

    • Erythroped works by preventing bacteria from producing proteins that are essential to them. Without these proteins the bacteria cannot grow, replicate and increase in numbers. Erythroped doesn’t directly kill the bacteria, but leaves them unable to increase in numbers. The remaining bacteria eventually die or are destroyed by the immune system. This treats the infection.
    • Erythroped is a broad-spectrum antibiotic that is active against a wide variety of bacteria that cause a wide variety of infections. Erythroped may be used to treat infections of the upper or lower airways, skin or soft tissue, eyes or ears. It may also be used to treat certain sexually-transmitted infections, oral and dental infections, and to prevent infections in people who are at risk, for example due to surgery, trauma or burns.
    • Erythroped is also used for treating inflammatory acne, as it is active against the bacteria associated with acne, Propionebacterium acnes. This is a common type of bacteria that feeds on sebum produced by the sebaceous glands in the skin. It produces waste products and fatty acids that irritate the sebaceous glands, making them inflamed and causing spots. By controlling bacterial numbers, erythrocin brings the inflammation of the sebaceous glands under control, and allows the skin to heal. (Other antibiotics may be preferred for acne however, as strains of the Propionebacterium that are resistant to erythrocin are becoming widespread.)
    • To make sure the bacteria causing an infection are susceptible to erythrocin your doctor may take a tissue sample, for example a swab from the throat or skin.
    • Erythroped has a similar range of antibacterial activity to penicillin and so is also useful as an alternative to penicillin in people who are allergic to penicillins.
