They used to offer it here: http://www.southwestmedicalgroup.com/index.asp but I don't if they still do. They used to have a drug name and a price list. Either they don't have it anymore or you have to register to see it. I thought that I had registered but my login isn't working.

I came here originally looking for Tussionex too. I have a chronic cough due to sinus allergies accompanied by debilitating sinus headaches and complete with stress incontinance. After looking around for a while and talking to some people I decided to go with regular hydro 10/325 (from NWW but there are others.) That controls my sinus problems and cough when I can take it regularly. I also take Claritin every day and take my hydro with some Chlortrimiton sometimes. That does cause drowsiness though so I can't always take that with the hydro.

The difference, as I understand it is that the Tussionex is sustained release so it lasts for 12 hours. It also has an antihistimine in it like Chlortrimiton. There is no other sustained released hydro as far as I know. ??
