For Healthcare Professionals

Applies to terbutaline: compounding powder, inhalation aerosol, inhalation aerosol with adapter, injectable solution, oral tablet

General

Common adverse effects include palpitations, chest pain, rapid heart rate, tremor or nervousness.[Ref]

Cardiovascular

Changes in heart rate of approximately 30% may be observed following 5 mg of terbutaline given orally. Aggravation of angina may be due to the tachycardia induced by terbutaline. Prolongation of the QT interval occurred in ten healthy males given a bolus injection of 0.25 mg terbutaline followed by an infusion of 5 mcg/min. Supraventricular ectopic beats and ventricular tachycardia have also been reported. Higher dosages of terbutaline should be used with caution in patients with cardiac disease, arrhythmias, or hypertension. All of these effects are dose-related and lower doses may be tolerated.

In one case-control study a positive association was found between the use of oral terbutaline for longer than 9 days and peripartum cardiomyopathy. Further study is needed to determine if a causative relationship exists.[Ref]

Very common (10% or more): Palpitations (up to 22.9%)

Common (1% to 10%): Tachycardia, extrasystoles ventricular, vasodilation, decrease in diastolic pressure, hypotension

Rare (less than 0.1%): Arrhythmias, e.g. atrial fibrillation, supraventricular tachycardia and extrasystoles; peripheral vasodilation; myocardial ischemia

Frequency not reported: Ectopic beats

Postmarketing reports: An increased tendency to bleeding in connection with caesarean section[Ref]

Nervous system

Very common (10% or more): Tremor (up to 38%), nervousness (up to 35 %), drowsiness (up to 11.7%), dizziness (up to 10.2%)

Common (1% to 10%): Headache

Uncommon (0.1% to 1%): Paresthesia

Postmarketing reports: Behavioral disturbances, such as agitation and restlessness[Ref]

Dermatologic

Common (1% to 10%): Sweating

Uncommon (0.1% to 1%): Rash

Frequency not reported: Exanthema

Postmarketing reports: Urticaria[Ref]

Gastrointestinal

Common (1% to 10%): Nausea, vomit

Uncommon (0.1% to 1%): Dry mouth

Frequency not reported: Bad taste, diarrhea

Postmarketing reports: Mouth, throat irritation[Ref]

Local

Common (1% to 10%): Pain at the injection site[Ref]

Metabolic

Common (1% to 10%): Hypokalemia

Rare (less than 0.1%): Lactic acidosis, hyperglycemia[Ref]

Infusions of terbutaline, 25 mcg/min, in women in premature labor has caused decreases in serum potassium of up to 1.6 to 2 mEq/L. Another study in ten healthy males produced a mean decrease in serum potassium of 0.9 mEq/L following a bolus injection of 0.25 mg terbutaline, followed by an infusion of 5 mcg/min. A decrease in magnesium of 0.08 mmol/L was produced in these same patients.

This fall in potassium is presumably due to an intracellular shift of potassium secondary to hyperglycemia and hyperinsulinemia.[Ref]

Other

Common (1% to 10%): Weakness, flashed feeling, asthenia[Ref]

Respiratory

Common (1% to 10%): Dyspnea, chest discomfort

Uncommon (0.1% to 1%): Pulmonary edema

Rare (less than 0.1%): Wheezing immediately after inhalation

Postmarketing reports: Paradoxical bronchospasm[Ref]

Musculoskeletal

Uncommon (0.1% to 1%): Muscle cramps, hypertonia

Frequency not reported: Muscle twitching[Ref]

Hepatic

Rare (less than 0.1%): Elevation of liver enzymes[Ref]

Hypersensitivity

Rare (less than 0.1%): Hypersensitivity vasculitis

Postmarketing reports: Hypersensitivity reactions including angioedema, bronchospasm, hypotension and collapse[Ref]

Psychiatric

Common (1% to 10%): Somnolence, insomnia

Uncommon (0.1% to 1%): Anxiety, hallucinations

Postmarketing reports: Sleep disorders, hyperactivity[Ref]
