Pregnant women should not use terbutaline to stop or prevent premature labour, especially if they are not in a hospital. When terbutaline was utilised for this reason, pregnant women who took the medicine experienced severe negative effects, including death. Terbutaline has also had a negative impact on newborns whose moms used it to induce or halt labour.

Why is this medication prescribed?

Terbutaline is used to both prevent and treat the wheezing, chest tightness, and shortness of breath brought on by emphysema, chronic bronchitis, and asthma. Beta agonists are a group of drugs that includes terbutaline. It facilitates breathing by calming down and widening the airways.

How should this medicine be used?

Terbutaline is available as an oral tablet. The tablets are typically taken once every six hours, three times per day. Ask your doctor or pharmacist to explain any instructions on your prescription label that you are unsure about following. Terbutaline should only be used as prescribed. Never take it in larger or less amounts or more frequently than directed by your doctor.

For at least 6 hours after you take each dose of terbutaline, your symptoms should be under control. Call your doctor if you notice that your symptoms worsen, return before the time for your next dose, or that terbutaline is not controlling them as well as it was at the beginning of your therapy. These can be indicators that things are becoming worse for you.

Terbutaline may help you manage your symptoms, but it won’t make your disease go away. Even if you feel OK, keep taking terbutaline. Without consulting your doctor, do not stop taking terbutaline.

Other uses for this medicine

What should I know about storage and disposal of this medication?

Keep this medication tightly closed in the original container and out of the reach of children. Store it away from excessive heat and moisture at room temperature (not in the bathroom).

Unused prescriptions must be disposed of carefully to prevent pets, kids, and other people from ingesting them. You should not, however, dispose of this medication in the toilet. Instead, utilising a medicine take-back programme is the easiest approach to get rid of your medication. To find out about take-back programmes in your area, speak with your pharmacist or the garbage/recycling department in your city. If you do not have access to a take-back programme, see the FDA’s Safe Disposal of Medicines website at for additional information.

As many containers (such as weekly pill minders and those for eye drops, creams, patches, and inhalers) are not child-resistant and are simple for young children to open, it is crucial to keep all medications out of sight and out of reach of children. Always lock safety caps and promptly stash medication up and away from young children where it is out of their sight and reach to prevent poisoning.

In case of emergency/overdose

Call the poison control hotline at 1-800-222-1222 in the event of an overdose. Additionally, information can be found online at Call 911 right once if the person has collapsed, experienced a seizure, is having difficulty breathing, or cannot be roused.

Overdose symptoms could include:

  • Chest pain
  • Hammering, rapid, or erratic heartbeat
  • Fainting or vertigo
  • Nervousness
  • Headache
  • Body part shaking that is uncontrollable
  • Excessive fatigue
  • Having trouble falling or staying asleep
  • Weakness
  • Mouth ache
  • Seizures

What other information should I know?

Keep all of your doctor’s appointments.

No one else should take your medication. Any queries you may have regarding medication refills should be directed to your pharmacist.

You should keep a written record of every medication you take, including any over-the-counter (OTC) items, prescription drugs, and dietary supplements like vitamins and minerals.
