The best things to "take" are time, fluid and rest.
Most headaches will go away without medication. Fatigue & dehydration
cause many headaches. Other headaches are caused by things that can be easily identified and avoided (smoke, odors, etc). Tylenol
) is safe, but if your headache
does not go away with the above measures it is better to see a doctor and find a cause rather than to mask it.
