Why is it prescribed?

Orciprenaline is used to treat symptoms of asthma and bronchospasm that may occur with COPD (e.g. bronchitis and emphysema).

Products that have this ingredient include •AA-Orciprenaline syrup •

See other drugs used in the treatment of •asthma •bronchospasm associated with COPD •COPD •emphysema (COPD) •

Along with its needed effects, orciprenaline may cause some unwanted or undesirable effects. Generally, orciprenaline is well tolerated and many people will not experience unwanted effects. The severity and duration of these effects are dependant on many factors including duration of therapy, dose, route of administration and individual response. Possible unwanted effects include:

  • nervousness
  • headache
  • slight palpitations (awareness of heart beat)
  • increased heart rate
  • tremor


  • bad taste
  • changes in blood pressure
  • muscle cramps
  • allergic reactions

Many of these unwanted effects, especially the most common ones, may disappear with continued use. Check with the doctor or pharmacist if any of them continue or become bothersome.


Orciprenaline is a bronchodilator that acts at receptors in the body called beta-adrenergic receptors. Stimulating these receptors in the bronchial smooth muscle causes the muscle to relax, allowing the bronchial tubes to dilate (widen). This bronchodilation relieves spasm or contraction of the muscle, allowing air to move in and out of the lungs more freely.

Use as directed. Never exceed the maximum dosage set by your physician. If you find that you are not responding to your usual dose, your asthma may be worsening and you should contact your physician. Increasing the dose, especially over extended periods, can lead to tolerance. Keep in mind that the bronchodilator action should last between 3 and 6 hours.
If you are using orciprenaline for an acute asthma attack and the condition continues or worsens, stop using the orciprenaline and call your doctor.
