Erythromycin Info

What Is erythromycin?

Erythromycin belongs to a class of medicines called macrolide antibiotics, which are designed to fight bacteria. It is the active compound in many erythromycin products available in Australia.

What Is erythromycin Used For?

Erythromycin is commonly used for chest infections that cause coughing and fever, skin infections that lead to redness or drainage, ear infections that bring pain and hearing loss, and throat infections that cause sore throats. Some people also take it for certain sexually transmitted infections or to aid in treating gastric ulcers caused by Helicobacter pylori. In general, it is prescribed for adults and children who need an antibiotic that works well against a range of common bacteria.

How Does erythromycin Work in the Body?

After you swallow the medicine, erythromycin is absorbed and travels through your bloodstream to the infection site. It interferes with the bacteria's ability to make proteins, which stops them from growing and multiplying. Your immune system can then clear the remaining bacteria.

What Should You Know Before Using It?

Women who are pregnant, planning a pregnancy, or breastfeeding should use erythromycin only if a health professional believes the benefit outweighs any risk. People with severe liver disease or an existing irregular heartbeat should also exercise caution. Alcohol can increase the chance of stomach upset, and certain medicines-such as antacids, some heart drugs, and some cholesterol-lowering agents-may interact with erythromycin. Always read the specific medication's labeling for a complete list of possible interactions.

  • Avoid use if you have a known allergy to macrolide antibiotics.
  • Check for liver problems, especially if you have a history of liver disease.
  • Discuss any heart rhythm issues with your health provider before starting the medication.

What Are the Side Effects of erythromycin?

Common Side Effects

  • Upset stomach or feeling of fullness.
  • Diarrhoea that may be mild to moderate.
  • Nausea or occasional vomiting.
  • Abdominal cramps or gas.
  • Changes in taste, often described as a metallic flavour.
  • Mild skin rash or itching.

Serious Side Effects

  • Severe diarrhoea that could indicate a Clostridioides difficile infection - stop use and get help immediately.
  • Signs of an allergic reaction, such as hives, swelling of the face, or breathing difficulties - stop use and get help immediately.
  • Yellowing of the skin or eyes suggesting liver problems - stop use and get help immediately.
  • Irregular heartbeat or fainting - stop use and get help immediately.
  • Serious skin reactions like blistering or peeling - stop use and get help immediately.

Who Is Most at Risk?

Older adults, people with liver impairment, and those taking other medicines that affect heart rhythm tend to notice side effects more often. Children may experience stomach upset more frequently than adults. Individuals with a history of allergic reactions to antibiotics should be especially vigilant.

Storage and General Use

Store erythromycin at room temperature, away from direct sunlight, heat, and moisture. Keep the medication out of reach of children and do not use it after the expiration date printed on the label. For detailed usage, dosing, and administration, refer to the specific medication's clinical information.
