Makes it easier to breathe.
Our pharmacists’ bottom line
Brethine (Terbutaline) is effective at preventing asthma attacks, but isn’t the first choice. It’s generally well-tolerated, but let your doctor know if you feel more lightheaded or have a rapid heartbeat while taking this medicine.
- Brethine (Terbutaline) is effective at preventing and reversing constriction in the airways due to asthma, bronchitis, and emphysema.
- Available in a generic form.
- Good choice for asthma if you find it hard to use inhalers properly.
- Only lasts about six hours.
- Can raise your blood sugars. If you have diabetes, check your sugars regularly and let your doctor know if they’re higher than usual.
- Takes about 30 to 45 minutes to start working, so it won’t help an asthma attack once it starts.
