What is the typical subcutaneous dosage for Terbutaline used to stop contractions?

The typical subcutaneous dosage for Terbutaline when used to stop contractions is 0.25 mg every 15 minutes. This dosing regimen is designed to provide rapid and effective tocolysis, particularly in situations such as preterm labor.

Terbutaline is a beta-adrenergic agonist that acts to relax smooth muscle, which makes it effective for inhibiting contractions in the uterus. Administering 0.25 mg at 15-minute intervals allows for careful monitoring of the mother and fetus while providing adequate drug levels to achieve the desired effect.

Using this dosage helps to avoid potential side effects that could arise from higher doses or more frequent administration. Additionally, the established practice typically limits the total amount of Terbutaline given over a specific period to minimize the risk of adverse effects, such as tachycardia or other cardiovascular issues. This regimen strikes a balance between effective contraction suppression and safety for both the mother and the baby.
