Erythromycin injection is given as an infusion into a vein, for a severe infection. A healthcare provider will give your first dose and may teach you how to properly use the medication by yourself.
Read and carefully follow any Instructions for Use provided with your medicine. Do not use erythromycin if you don't understand all instructions for proper use. Ask your doctor or pharmacist if you have questions.
Prepare an injection only when you are ready to give it. Do not use if the medicine looks cloudy, has changed colors, or has particles in it. Call your pharmacist for new medicine.
You may need to shake the liquid medicine before you measure a dose. Use the dosing syringe provided, or use a medicine dose-measuring device (not a kitchen spoon).
You must chew the chewable tablet before you swallow it.
Do not crush, chew, or break a delayed-release capsule or tablet. Swallow it whole.
