How should I use this medication?
Adults: The recommended adult dose is 250 mg every 6 hours, 500 mg every 12 hours, or 333 mg every 8 hours. The maximum daily dose is 4 g. The exact dose and the length of treatment depends on the condition being treated.
Erythromycin enteric-coated pellets are available in capsules and can be taken without regard to meals. Taking the medication with food may reduce the risk of stomach upset.
Erythromycin 250 mg and 333 mg capsules (enteric-coated pellets) are not recommended for sprinkling, since the capsules are very full and some of the medication may be lost through spillage. If you must open the capsule, take care to open it over food so as not to lose any of the pellets.
To open the capsule, hold it with the clear end down. Gently twist off the cap. Sprinkle the entire contents of the capsule on a spoonful of applesauce, fruit jellies, ice cream, or other pleasant-tasting semi-solid food. Do not chew or crush the pellets. Swallow the spoonful of food and drink some water to make sure all the pellets are swallowed. If the pellets are accidentally spilled, start over with a new capsule and a new serving of food.
Children: The recommended dose for children depends on the age, weight, and condition of the person being treated.
Finish all of this medication, even if you start to feel better.
