Hello Clay70,
These doses of
tylenol are very unlikely to do any damage to the liver. The recommendation is not to exceed 4 grams of
tylenol per day. The doses you are taking are far from this.
The codeine part is also pretty small so it is less likely for you to develop tolerance to this. If you find that you are not getting as much effect over the years it may be that you are becoming tolerant but I don't think this is likely to happen. Also, at this doses, it is unlikely for you to develop any significant dependence on the codeine.
Other options besides
tylenol basically include
ibuprofen and the other non-steroidal anti-inflammatories. There are some
ibuprofen/narcotic combinations but they tend to be a fair amount stronger than
tylenol 3. If needed, your doctor can discuss these with you.
Best wishes.
