COPD Home > Combivent Overdose

If you take too much Combivent, overdose symptoms could include headaches, blurred vision, and chest pain. The effects will vary, depending on how much Combivent was taken and whether it was taken with other drugs. Treatment for a Combivent overdose typically includes supportive care, which consists of treating the symptoms that occur as a result of the overdose.

Combivent Overdose: An Overview

Combivent® (ipratropium and albuterol inhaler) is a prescription medication used to treat chronic obstructive pulmonary disease (COPD). It contains two different medications: ipratropium (an anticholinergic medication) and albuterol (a beta agonist). The effects of a Combivent overdose will vary, depending on a number of factors, including the Combivent dosage and whether it was taken with any other medicines or substances. If you happen to take too much Combivent, seek immediate medical attention.
In order to comply with the Montreal Protocol on Substances That Deplete the Ozone Layer, Combivent inhalers (in their original form) will not be available after July 2013 because they contain chlorofluorocarbons (CFCs), chemicals that deplete the ozone layer. A new formulation, Combivent Respimat, became available starting in October 2012. People using the old Combivent inhaler will need to get a new prescription in order to switch to the new Combivent Respimat inhaler.
