Your doctor will tell you how much medicine to take and how often.
It is very important for you to take this medicine on a regular schedule. This may include waking up during the night to take the medicine. Make sure you understand how often you will need to take the medicine.
You may take this medicine with or without food.
If a dose is missed:
Take the missed dose as soon as possible unless you are more than 1 hour late.
If you are more than 1 hour late, skip the missed dose and return to your usual schedule.
You should not use two doses at the same time.
If you are using this medicine during pregnancy and you miss a dose, your contractions may start again. Call your doctor right away if you start having contractions.
Check with your doctor before taking terbutaline if you have high blood pressure, heart disease, a thyroid disorder, or diabetes, or if you are pregnant or breastfeeding (if you are being treated with terbutaline for a lung disorder).
If you are being treated for a lung disorder, and this medicine does not help your breathing or if your condition gets worse while you are using it, call your doctor.
If you are taking this medicine to keep you from going into labor, your doctor may want you to stay in bed as much as possible and rest. You may need to wear a monitor in a hospital or clinic to check for uterine (womb) activity.
Follow your doctor's orders, and make sure you know what signs to look for so you will know if you are going into labor.
