Combivent

• If you miss a dose...
  Take the forgotten dose as soon as you remember. However, if it is almost time for your next dose, skip the one you missed and return to your regular schedule. Do not take two doses at once.

• Storage instructions...
  Store at room temperature. Protect from heat; temperatures of 120 degrees Fahrenheit can cause the canister to burst. Do not puncture the canister or discard it in an incinerator. Protect from high humidity.

What side effects may occur?

Side effects cannot be anticipated. If any develop or change in intensity, tell your doctor as soon as possible. Only your doctor can determine if it is safe to continue using Combivent.

• Side effects may include:
  Bronchitis, coughing, headache, shortness of breath, upper respiratory tract infection

Why should Combivent not be prescribed?

You'll have to avoid Combivent if either of its ingredients have ever given you an allergic reaction. Avoid it, too, if you've had a reaction to atropine-containing drugs, or if you are allergic to peanuts, soybeans, or soy lecithin.

Special warnings about Combivent

Instead of opening the airways, Combivent sometimes causes them to close. This reaction—which can be life-threatening—is most likely to occur after the first use of a new canister. If you suffer severe breathing difficulties after a dose of Combivent, stop using it and see your doctor immediately.

The albuterol in Combivent has been known to raise heart rate and blood pressure. It can also cause changes in heart rhythm. If you have a weak heart, an irregular heartbeat, high blood pressure, or any other heart problem, you'll need to use Combivent with caution. If it triggers heart-related symptoms, check with your doctor at once. The product may have to be discontinued.

A severe allergic reaction can follow the first dose of Combivent. Possible symptoms include swelling of the face, mouth, or throat; hives, skin rash, breathing difficulties, or even collapse. Seek emergency care immediately if these symptoms occur.
