Eryc (erythromycin) is a macrolide antibiotic used in the treatment of many different kinds of infections including skin infections, respiratory tract infections including pneumonia, sexually transmitted diseases, diphtheria, and whooping cough (pertussis). Eryc is available in generic form as erythromycin. Side effects of Eryc include nausea, vomiting, stomach pain or cramps, loss of appetite, diarrhea, skin rash or itching, dizziness, headache, feeling tired, or vaginal itching or discharge.

The usual adult dose of Eryc is 250 mg every 6 hours taken one hour before meals. Pediatric dosing of Eric is based on the child's age, body weight, and severity of infection. Many drugs can interact with Eryc, such as Parlodel (bromocriptine), Lanoxin (digoxin), Xanax (alprazolam), and Viagra (sildenafil). This list is not complete and there are many other drugs that can interact with Eryc. There are no known adverse effects of erythromycin in pregnancy, but controlled studies have not been carried out. Erythromycin is excreted in human milk, and caution should be exercised when Eryc is administered to a breastfeeding woman.
