ADULT DOSE:
|
|
Tocolytic-
Initial: Intravenous, 50 to 100 mcg (0.05 to 0.1 mg) per minute, increased every ten minutes as necessary in increments of 50 mcg (0.05 mg) to the effective dose that balances uterine response and unwanted effects (increased maternal heart rate and decreased blood pressure and increased fetal heart rate), or until the maternal heart rate reaches 130 beats per minute.
Maintenance: Intravenous, 150 to 350 mcg (0.15 to 0.35 mg) per minute at the lowest dose that maintains a relaxed uterus; however, as soon as labor is irreversible or the maximum dose of 350 mcg (0.35 mg) per minute is reached, ritodrine should be discontinued.
Note: Injection must be diluted before use unless premixed solution is used. Intravenous infusion should be continued for twelve to forty-eight hours after uterine contractions stop. Ritodrine should be administered in a separate intravenous line. Other medications of any type should not be administered via the same tubing. |
