Yes, both tylenol and hylands tabs may be taken together. Hylands is a homeopathic formula, all natural and a good alternative for prescription meds and OTC meds.
You may also want to try a homeopathic version for symptoms currently prompting you to use Tylenol.
The following major health stores have good alternatives depending on your (US)geographical location:
Whole Foods
Vitamin World
Jimbos
Hope this helps
