PATIENT MEDICATION

Erythromycin

 

Description

Erythromycin (also called Ery-Tab®, E-Mycin®, EES®, PCE®, and ERYC®) is used to prevent or treat infections. It is also taken by mouth to improve stomach emptying time and how well the intestines work. It is applied to the skin to treat acne. Erythromycin is available in many different forms, brands, and strengths, including the following:

  • Capsules, tablets (some are extended-released), and liquid suspensions, all of which are taken by mouth
  • Clear liquid to be given by vein (IV)
  • Eye ointment
  • Skin ointment and solution

How to take and store erythromycin

  • Some brands of erythromycin must be taken on an empty stomach, one (1) hour before meals or 2 hours after a meal. Other brands can be taken with or without food. Ask your pharmacist if you can take your medicine with food.
  • Shake the liquid well before you take it. Use an oral syringe or medicine cup to be sure you are taking the correct amount.
  • Most brands of erythromycin liquid medicines should be kept in the refrigerator. Ask your pharmacist if you need to keep your medicine in the refrigerator.
  • Discard the liquid medicine after the date printed on the label. Throw away any unused eye ointment when it reaches the expiration date.
  • Store all tablets and capsules at room temperature in a dry place.
  • Do not crush, cut, or chew the extended-release tablets or capsules. Swallow them whole.

Special instructions

  • Before taking erythromycin, tell your doctor if you have had an allergic reaction to erythromycin in the past.

  • While taking erythromycin, if you have yellowing of the eyes or skin, yellow-brown urine, or severe or watery diarrhea, tell your doctor right away.
  • Finish all doses of this medicine as your doctor told you, even if you think your condition is better. Do not stop taking this medicine unless your doctor tells you to do so.

  • Follow these guidelines if you are using the eye ointment:
    • Wash your hands before and after use.
    • Tilt your head back and pull your lower eyelid down with your index finger to form a pouch. Squeeze the end of the tube to apply a thin layer of the ointment inside the lower eyelid.
    • Close the eye gently to spread the ointment over the eye.
    • Try not to touch the end of the tube to your eye, fingertips, or any other surface.
    • Your vision may blur for a few minutes after applying the ointment.
    • Even if your eye infection seems better after a few doses, apply all the doses of the ointment that your doctor prescribed.
    • If you have burning or stinging in the eye, continued blurred vision, or redness and swelling of the eye, tell your doctor right away.
