- Monitor frequency, duration, and force of contractions and uterine resting tone. Notify physician or other health care professional if contractions are absent or last more than 1 min.
- Monitor temperature, pulse, and BP periodically throughout course of therapy. Large dose may cause hypertension. Temperature elevation beginning 1 to 16 hr after initiation of therapy and lasting for several hours is not unusual.
- Auscultate breath sounds. Wheezing and sensation of chest tightness may indicate hypersensitivity reaction.
- Assess for nausea, vomiting, and diarrhea. Vomiting and diarrhea occur in approximately two-thirds of patients. Premedication with antiemetic and antidiarrheal is recommended.
