Do not use erythromycin if you or your child are also using astemizole (Hismanal®), cisapride (Propulsid®), pimozide (Orap®), or terfenadine (Seldane®). Using these medicines together may increase risk for more serious side effects.

Make sure your doctor knows if you are pregnant or may be pregnant before taking erythromycin.
Erythromycin may cause diarrhea, and in some cases it can be severe. It may occur 2 months or more after you stop using erythromycin. Do not take any medicine to treat diarrhea without first checking with your doctor. Diarrhea medicines may make the diarrhea worse or make it last longer. If you have any questions about this or if mild diarrhea continues or gets worse, check with your doctor.
Before you have any medical tests, tell the medical doctor in charge that you or your child are using erythromycin. The results of some tests may be affected by erythromycin.
