What medication should be readily available for tachysystole during Oxytocin administration?

Tachysystole refers to an abnormally high frequency of uterine contractions, which can occur during Oxytocin administration. In such cases, it is crucial to have a medication that can effectively relax the uterus and decrease the contraction frequency. Terbutaline, a tocolytic agent, is specifically used in these scenarios to halt or diminish uterine contractions. It works by stimulating beta-2 adrenergic receptors, resulting in smooth muscle relaxation.

This makes terbutaline the appropriate choice for managing tachysystole because it directly targets the underlying problem by alleviating excessive uterine activity, which is critical for ensuring fetal well-being and managing any distress that may arise from overly frequent contractions.
