You should ask your pharmacist. I don't know how much hydrocodone Tussionex has in it, but I wouldn't take both of them. Both medications contain hydrocodone, which you probably already know. That is a very strong narcotic and not one you want to OD on. You can take as much as 10 mg of hydrocodone at a time. That could leave yoy feeling quite out of it though if it is too much for your system. I would probably wait 6 hours from the lortab to take the tussionex.
