What should I discuss with my healthcare provider before taking erythromycin?
You should not take erythromycin if you are allergic to it, or if you are taking any of the following medicines. Erythromycin may interact with these medicines and could cause dangerous or life-threatening heart rhythm disorders.
To make sure you can safely take erythromycin, tell your doctor if you have any of these other conditions:
FDA pregnancy category B. Erythromycin is not expected to harm an unborn baby. Tell your doctor if you are pregnant or plan to become pregnant during treatment.
Erythromycin can pass into breast milk and may harm a nursing baby. Do not use this medication without telling your doctor if you are breast-feeding a baby.
Older adults may be more likely to have side effects on heart rhythm, including a life-threatening fast heart rate.
How should I take erythromycin?
Take 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 erythromycin with or without food.
Do not crush, chew, break, or open an erythromycin 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 erythromycin.
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. Erythromycin will not treat a viral infection such as the common cold or flu.
Store at room temperature away from moisture and heat, unless otherwise directed on the medicine label.
