If you take too much DuoNeb, overdose symptoms may include chest pain, seizures, or shakiness. The effects of an overdose will vary, based on how much DuoNeb was taken and whether it was taken with other drugs. Treatment for a DuoNeb overdose typically consists of treating the symptoms as they occur, known as supportive care.

DuoNeb Overdose: An Overview

DuoNeb® (ipratropium and albuterol solution) 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 DuoNeb overdose will vary, depending on a number of factors, including the DuoNeb dosage and whether it was taken with any other medicines or substances. If you happen to overdose on DuoNeb, seek immediate medical attention.
