Other Preventers

Other preventers are Intal® and Tilade®. They are non-steroidal and again used to reduce inflammation.

sodium cromoglycate (Intal®)
      - for mild asthma
      - this can protect against the effects of cold air and exercise
      - it requires 4-6 weeks to be effective
      - it has few side effects.

nedocromil (Tilade®)
      - is similar to Intal®
      - is requires 3-4 weeks to be effective
      - it has a bad taste
      - it has fewer doses/canister; therefore, you will probably need more than one canister per month.

ketotifen (Zaditen®)
      - is used for mild asthma
      - it can be useful for asthmatics who also suffer from hay fever
      - it helps to reverse inflammation of the airways
      - it can be used orally and comes in tablets or syrup

B2-Agonists are rescue medications which:

          o Relax the muscles around the airways which allows the breathing to become much easier within minutes.
          o Are used only when needed and rarely on a regular basis, unless the asthma is under inadequate control.
          o Make the airway muscle less likely to contract.
          o Are usually in blue devices.

When to use B2 Agonists

          o to relieve symptoms of cough, chest tightness, wheezing and shortness of breath
          o a few minutes before exercising or before exposure to any trigger known that might worsen asthma

Side effects of B2-Agonists include:
