Sudafed

Sudafed is a brand name and registered trademark for over the counter (OTC) decongestants manufactured by McNeil Laboratories (a division of Johnson & Johnson) for sale in Australia, New Zealand, Canada, Ireland, South Africa, the United Kingdom, and the United States. Before being acquired by Johnson & Johnson in 2006, Sudafed was owned by Pfizer.

Sudafed is used to treat symptoms of the common cold, sinusitis and nasal congestion.

The original formulation of Sudafed contains the active ingredient pseudoephedrine, but formulations without pseudoephedrine are also being sold under the Sudafed brand.

The brand name Sudafed is used for several formulations that contain different active ingredients:

In the UK, some Sudafed-branded products containing phenylephrine also contain other active ingredients:

In late 2004, Pfizer publicly disclosed its plans to make available a new over-the-counter product, Sudafed PE, which does not include pseudoephedrine. Decongestants with other ingredients were completely converted to phenylephrine later in 2005. Original Sudafed is still offered behind the counter to customers 18 years of age or older upon request, requiring the customer to show ID and sign a sales log next to a record of their name and address.

The new product was prompted by existing and proposed restrictions on the availability of pseudoephedrine-based products. U.S. state laws imposing such restrictions were in response to pseudoephedrine's role as an ingredient used to synthesize the stimulant methamphetamine.
