A-Tan 12X suspension

Generic Name: guaifenesin/phenylephrine/pyrilamine (gwye-FEN-e-sin/fen-ill-EF-rin/peer-IL-a-meen)
Brand Name: A-Tan 12X and Ryna-12X

A-Tan 12X suspension is used for:

Relieving symptoms of sinus congestion, runny nose, sneezing, and throat and airway irritation due to colds, upper respiratory infections, and allergies. It may also be used for conditions as determined by your doctor.

A-Tan 12X suspension is an expectorant, decongestant, and antihistamine combination. The expectorant loosens mucus and lung secretions in the chest and makes coughs more productive. The decongestant works by constricting blood vessels and reducing swelling in the nasal passages, making it easier to breathe. The antihistamine works by blocking the action of histamine, which helps reduce symptoms such as watery eyes and sneezing.

  • you take sodium oxybate (GHB) or you have taken furazolidone or a monoamine oxidase (MAO) inhibitor (eg, phenelzine) within the last 14 days
