Which of these is a potential adverse effect of Terbutaline?

Tachycardia is a well-known potential adverse effect of Terbutaline, which is a beta-agonist medication primarily used as a bronchodilator and also for preventing preterm labor. It stimulates beta-adrenergic receptors, leading to increased heart rate. This effect occurs due to systemic absorption of the medication, which can cause an increase in cardiac output and a reflexive increase in heart rate.

While Terbutaline may have other side effects such as uterine relaxation, which is a desired effect in the context of its use to stop premature contractions, it is not considered an adverse effect. Severe headache and visual disturbances, although they can occur with various medications, are not commonly associated with Terbutaline. Therefore, tachycardia stands out as a significant and clinically relevant adverse effect of this medication, warranting monitoring and potential intervention by healthcare providers.
