Welcome to Just Answer and thanks for your question. The maximum allowable for acetaminophen for adults is 1,000 mg per dose and 4,000 mg per day. It is best to avoid alcohol when taking it, and take the minimum that will work for you.
You should be fine taking this amount of acetaminophen long term. The hydrocodone is another matter and you will probably need more of it as time goes by to control your pain. Continual use builds tolerance and additional medication is needed to provide the same level of pain control.
