Interactions:

Antacids: May enhance the adverse/toxic effect of MiSOPROStol. More specifically, concomitant use with magnesium-containing antacids may increase the risk of diarrhea. Management: Avoid concomitant use of misoprostol and magnesium-containing antacids. In patients requiring antacid therapy, employ magnesiumfree preparations. Monitor for increased adverse effects (e.g., diarrhea, dehydration). Risk X: Avoid combination

 Carbetocin: MiSOPROStol may enhance the adverse/toxic effect of Carbetocin. Specifically, Carbetocin oxytocic effects may be enhanced. Risk X: Avoid combination

Oxytocin: MiSOPROStol may enhance the adverse/toxic effect of Oxytocin. Specifically, oxytocic effects may be enhanced. Management: The manufacturer of misoprostol recommends avoiding concomitant use with oxytocin. Misoprostol may augment effects of oxytocin, particularly when given within 4 hours of oxytocin initiation. Risk D: Consider therapy modification

Phenylbutazone: May enhance the neurotoxic effect of MiSOPROStol. Specifically, the combination may result in headache, dizziness, and transient diplopia. Risk C: Monitor therapy
