Terbutaline (trade names Brethine, Bricanyl, or Brethaire) is a β2-adrenergic receptor agonist, used as a fast-acting bronchodilator (often used as a short-term asthma treatment) and as a tocolytic to delay premature labour. The inhaled form of terbutaline starts working within 15 minutes and can last up to 6 hours.
Terbutaline as a treatment for premature labour is an off-label use not approved by the FDA. Studies have suggested that terbutaline is a developmental neurotoxicant and may cause brain damage to the infant.
Maternal - tachycardia, nervousness, tremors, headache and possible pulmonary edema. Fetal - tachycardia and hypoglycemia. Terbutaline is preferred over Ritodrine because it has minimal effects on blood pressure.
