Patient leaflet - Bricanyl tablets 5 mg

1. What Bricanyl Tablets are and what they are used for

Bricanyl Tablets contain a medicine called terbutaline sulfate. This belongs to a group of medicines called beta-agonists. These work by relaxing certain muscles. For example, they open up the airways in the lungs.

  • Bricanyl Tablets are used for the regular treatment of breathing disorders such as asthma. They help to relieve tightening of the chest and difficulty breathing (bronchospasm). Bricanyl should not be used alone for the regular treatment of asthma or other breathing conditions. If you are using Bricanyl every day then your doctor should have also prescribed you another type of medication such as an “inhaled corticosteroid”, which helps reduce the swelling and inflammation in your lungs.

2. What you need to know before you take Bricanyl Tablets

Do not take Bricanyl Tablets:

  • If you are allergic to terbutaline sulfate or any of the other ingredients of this medicine (listed in Section 6). Warnings and precautions

Talk to your doctor or pharmacist before taking Bricanyl Tablets if:

  • You are pregnant and you have had problems with your pregnancy.
  • You are diabetic. If so, you may need some additional blood sugar tests when you start taking Bricanyl Tablets.
  • You have a history of heart disease, irregular heart rhythm or angina.
  • You have an overactive thyroid gland.
