Hi Betsey. I'm sorry that they changed your husband's job. It sounds like it's going to be really hard for him to do, and probably that he shouldn't be doing it because of his health. I hope that things work out, and that he is able to find something else.
Your dose of hydrocodone, which I believe is 10/660, is on the higher end in regard to the amount of acetaminophen in the medication. If you take more than 6 pills per day, then you are over the "safe" limit of acetaminophen per day, which is 4000 mg. For people who take APAP daily, the amount is lower. I think I have read that even the limit of 4000 mg. daily will be changed, as that it pretty high.
So, if you are taking more than six pills per day, then your APAP dose is already too high (in my opinion). But, some doctors do have patients who are on more that 4000 mg. daily APAP. I was one of them, years ago, and I thank God that my liver is okay. Not safe at all IMO.
If you doubled up, like you asked, then the amount of APAP would be much higher than would be safe.
They are, over the next three years (I believe), going to change all of the short acting meds. that contain APAP to have only 325 mg. or less, as per the FDA.
I would ask my doctor if he could prescribe Norco which comes in 10 mg. pills, but has only 325 mg. of APAP in it. I wouldn't be worried about doubling up on that amount, but I would not do it with the 10/660 Vicodin HPs. Actually, I would not ask my doctor for a specific medication, but I would tell my doctor that the Vicodin is not controlling my pain and ask for suggestions.
I don't think he will want you to double up on that though. I wouldn't want to...too unsafe.
Wow. Long answer. Sorry if it was a confusing reply!
