Terbutaline side effects -- which may include shakiness, drowsiness, and headaches -- are generally minor and easily treated. However, some side effects of terbutaline are more serious and should be reported to your healthcare provider right away, including an increased heart rate, diabetes, anxiety, and worsening breathing problems.
As with any medicine, there are possible side effects with terbutaline sulfate (Brethine®); however, not everyone who takes the medication will experience side effects. In fact, most people tolerate terbutaline well. When side effects do occur, in most cases they are minor and either require no treatment or can easily be treated by you or your healthcare provider.
(This article covers many, but not all, of the possible side effects with terbutaline. Your healthcare provider can discuss a more complete list of terbutaline side effects with you.)
Terbutaline has been studied thoroughly in clinical trials. In these studies, the side effects that occur in a group of people taking the drug are documented and are then compared to side effects that occur in another group of people not taking the drug. In these studies, the most common terbutaline side effects included:
- Nervousness -- in up to 35 percent of people
- Shakiness (tremors) -- up to 15 percent
- Headaches -- up to 7.5 percent
- Drowsiness -- up to 5.5 percent
- Heart palpitations (feelings of a rapidly or forcefully beating heart) -- up to 5 percent.
Some other common side effects, occurring in 1 percent to 4 percent of people, included:
