Erythromycin Dosage

Dosage instructions are determined by the type (and severity) of infection being treated and may vary slightly for different brands of Erythromycin. The following are recommended dosages for PCE, one of the most commonly prescribed brands.


Streptococcal Infections

The usual dose is 333 mg every 8 hours, or 500 mg every 12 hours. Depending on the severity of the infection, the dose may be increased to a total of 4 grams a day. However, when the daily dosage is larger than 1 gram, twice-a-day doses are not recommended, and the drug should be taken more often in smaller doses.

To treat streptococcal infections of the upper respiratory tract (tonsillitis or strep throat), Erythromycin should be taken for at least 10 days.

To prevent repeated infections in people who have had rheumatic fever, the usual dosage is 250 mg twice a day.

Urinary Tract Infections Due to Chlamydia Trachomatis During Pregnancy

The usual dosage is 500 mg of Erythromycin orally 4 times a day or 666 mg every 8 hours on an empty stomach for at least 7 days. For women who cannot tolerate this regimen, a decreased dose of 500 mg every 12 hours or 333 mg every 8 hours a day should be prescribed for at least 14 days.

For Those with Uncomplicated Urinary, Reproductive Tract, or Rectal Infections Caused by Chlamydia Trachomatis When Tetracycline Cannot Be Taken

The usual oral dosage is 500 mg of Erythromycin 4 times a day or 666 mg every 8 hours for at least 7 days.

For Those with Nongonococcal Urethral Infections When Tetracycline Cannot Be Taken

The usual dosage is 500 mg of Erythromycin by mouth 4 times a day or 666 mg orally every 8 hours for at least 7 days.

Acute Pelvic Inflammatory Disease Caused by Neisseria Gonorrhoeae

The usual treatment is three days of intravenous Erythromycin followed by 500 mg orally every 12 hours or 333 mg orally every 8 hours for 7 days.


The usual dosage is 30 to 40 grams divided into smaller doses over a period of 10 to 15 days.

Intestinal Infections

The usual dosage is 500 mg every 12 hours, or 333 mg every 8 hours, for 10 to 14 days.

Legionnaires' Disease

The usual dosage ranges from 1 to 4 grams daily, divided into smaller doses.


Age, weight, and severity of the infection determine the correct dosage.

The usual dosage is from 30 to 50 mg daily for each 2.2 pounds of body weight, divided into equal doses for 10 to 14 days. For pneumonia in infants due to chlamydia, treatment lasts at least 3 weeks.

For more severe infections, this dosage may be doubled, but it should not exceed 4 grams per day.

Children weighing over 44 pounds should follow the recommended adult dose schedule.

For prevention of bacterial endocarditis, the children's dosage is 10 mg per 2.2 pounds of body weight 2 hours before dental work or surgery, followed by 5 mg per 2.2 pounds 6 hours later.
