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.
