What are the indications for usage of Sotalol IV?

Sotalol IV is indicated for:

  • the treatment of documented, life-threatening ventricular arrhythmias, such as sustained ventricular tachycardia in adult and pediatric patients.
    Limitations of Use:
    Sotalol has not been shown to enhance survival in patients with life-threatening ventricular arrhythmias.
  • the maintenance of normal sinus rhythm (delay in time to recurrence of atrial fibrillation/atrial flutter (AFIB/AFL)) in adults and pediatric patients with highly symptomatic AFIB/AFL who are currently in sinus rhythm.
    Limitations of Use:
    Because sotalol can cause life-threatening ventricular arrhythmias, reserve its use for patients in whom AFIB/AFL is highly symptomatic.

What are the benefits of Sotalol IV over oral sotalol for adult patients?

Sotalol IV offers the same molecule as oral sotalol but in an intravenous formulation that presents multiple advantages over oral sotalol. Because 1 hour*1 of Sotalol IV infusion achieves the same maximum serum concentration as 3 days2 of oral sotalol administration, clinicians can more quickly determine patient response to sotalol at chosen therapeutic levels. This may allow hospital discharge in 20-24 hours1, compared to the 72-hour2 discharge typical with oral loading. These differences combine to potentially reduce patient length of stay, improve bed availability, and generally manage patients more effectively within an institution.

How do I learn more about sotalol, and how do I safely administer it in adults?

Have there been any recent studies published on Sotalol IV?

A selection of recent studies published on Sotalol IV can be found on our Research page.

Is allergen information available for Sotalol IV and the vial in which it is packaged?

1 mL of Sotalol IV is composed of 15 mg sotalol hydrochloride, q.s. water for injection, and 2.9 mg glacial acetic acid. 

The vial is made of glass, and the stopper is made of Datwyler FM257/2, which is latex-free. You can find more information on the composition of the stopper here.

How do I order Sotalol IV? Is there information on proper storage and shelf life?

You can find information on ordering and proper storage of Sotalol IV on our Ordering Info page.

What's the history of sotalol? When was the intravenous form introduced?

Sotalol is both a Class II and Class III antiarrhythmic. It was first synthesized and studied in the 1960s, and in 1992 the oral form was approved in the US for treatment of life threatening ventricular arrhythmias.2

The intravenous form of sotalol, today known as Sotalol IV, was initially approved by the FDA in 2009,3  but only as a substitute for oral therapy in patients unable to take oral medication, and remained largely unavailable until it was relaunched in 2015 by AltaThera Pharmaceuticals.

In 2020, Sotalol IV was approved for IV loading for oral maintenance.4 This approval was accomplished using the FDA Model-Informed Drug Development program, or MIDD. Because of previous pharmacokinetics data and the multitude of safety and efficacy studies already existing on oral sotalol, which is the same molecule, MIDD made the development and approval process much more efficient.

In 2025, Sotalol IV received an expanded label from FDA including a pediatric indication, further supporting Sotalol IV’s use in the treatment of dangerous arrhythmias that can be costly to treat; including atrial fibrillation, atrial flutter, and documented life-threatening ventricular arrhythmias such as sustained ventricular tachycardia.1 FDA also approved an update to the label to reflect a change to the renal function calculation for recommended adult loading, which now uses the patient’s estimated glomerular filtration rather than creatinine clearance.1 This adjustment brings the label more in line with current nephrology practice and enhances dosing to ensure safe and efficacious use of the drug.

Highlights of Prescribing Information

Boxed Warning, Indications, and Important Safety Information

WARNING: LIFE THREATENING PROARRHYTHMIA

Sotalol can cause life threatening ventricular tachycardia associated with QT interval prolongation. To minimize the risk of drug induced arrhythmia, initiate or uptitrate intravenous sotalol in a facility that can provide continuous electrocardiographic monitoring and cardiac resuscitation [see Dosage and Administration (2.3) and Warnings and Precautions (5.1)].
Do not initiate intravenous sotalol therapy if the baseline QTc is longer than 450 ms. If the QTc prolongs to 500 ms or greater, reduce the dose or discontinue.
