Terbutaline sulfate (Brethine®) is a medication approved for the treatment of breathing conditions like asthma and emphysema. It comes in tablet form and is generally taken three times a day. Although most people can safely take terbutaline, it is not appropriate for everyone. For example, people with epilepsy, diabetes, or congestive heart failure may need to take a different medication, as may women who are pregnant or breastfeeding.
Part of taking this medication safely means taking terbutaline exactly as your healthcare provider prescribes and asking him or her about side effects to watch out for. Common ones include tremors, dizziness, and headaches, but if you experience anything that just "does not seem right" during treatment, contact your healthcare provider.
