Global Patient Feedback for Acetaminophen (Tylenol) ( Post a comment )
Question/Comment:
I take Hydrocodone/Acidemephen every 8 hours. I have had 2 unsuccessful cervical fusions and the pain in my head, neck and shoulders is so severe that the medication doesn't seem to help. However, I have tried to take only over the counter medications instead and my pain becomes unbearable then.
If anyone has suggestions I am open to hearing them.

Question/Comment:
I am currently taking 2 Reg Strenght Tylenol ( 2X325mg)three times a day for arthritis pain. My Dr. agrees that this is a safe dosage. My liver function tests have been normal. I try to keep it to twice a day (i.e.650mg twice a day) when the pain is well controlled. Can I keep this up indefinitely?

iGuard Answer/Reply:
This is a safe dose of Tylenol. The maximum recommended dose is 4000 mg daily, and you are currently taking 1300 mg. If you are going to stay on Tylenol, it would be a good idea to continue to have your liver function monitored on a regular basis.
