Precautions
On March 9, 2006, The Combat Methamphetamine Epidemic Act of 2005 was enacted which requires sellers of this drug ensure that: employees have been trained; records of the training are being maintained; sales limits are being enforced; products are being stored appropriately; and a written or electronic logbook is being maintained. The law requires that retailers place pseudoephedrine products where customers do not have direct access to such products before a sale is made. The FDA defines pseudoephedrine as an OTC drug in accordance with the monograph and FDA regulations.
The US FDA strongly recommends that over- the- counter (OTC) cough and cold products not be used in children younger than 2 years of age because serious and potentially life-threatening side effects can occur including death, convulsions, rapid heart rates, and decreased levels of consciousness. OTC cough and cold products include decongestants, expectorants, antihistamines, and antitussives.
Safety and efficacy have not been established in patients younger than 2 years.
