Is Tussionex Suspension an MAOI or SSRI?

Tussionex is neither a SSRI or a MAOI, Tussionex Extended-Release Suspension is a cough-suppressant/antihistamine combination used to relieve coughs and the upper respiratory symptoms of colds and allergies. Hydrocodone, a mild narcotic similar to codeine, is believed to work directly on the cough center. Chlorpheniramine, an antihistamine, reduces itching and swelling and dries up secretions from the eyes, nose, and throat.
