What are Acetaminophen and Ibuprofen?

Tylenol ( acetaminophen ) reduces fevers and pains. It functions primarily in the brain and lowers how much pain your body feels.

It is mainly administered as acetaminophen when it comes to treating a headache, particularly in cases of tension headache and migraines.

It is medicated by taking a nonsteroidal anti-inflammatory drug (NSAID), ibuprofen (Advil, Motrin). It decreases pain, fever, and inflammation.

Ibuprofen tends to work quicker and leave a better effect in case your headache or any other body pain has an inflammatory nature.

What is the Difference in the Way They are Working?

Both of the medicines are effective in treating pain, but in different ways in your body:

  • Acetaminophen prevents the transmission of pain in the brain.
  • Ibuprofen decreases the hormones (prostaglandins) that cause inflammation and swelling.

That is why when you have a headache then the decision between the use of acetaminophen for headache and of ibuprofen will depend on the reason that is causing your head to feel painful.

What is Better to Use in Neck Pain?

The other popular question would be:

Tylenol or Ibuprofen for neck pain?

Tylenol could help in case your neck pain is the result of muscle strains or your poor posture (when you sit at the computer all day long).

In case your neck pain is due to inflammation (arthritis, injury, muscle swelling), then you must choose Ibuprofen since it combats pain as well as inflammation.

Ibuprofen or Tylenol for Muscle Pain?

That is where the knowledge of the cause comes in handy.

Acetaminophen for muscle pain is sufficiently effective in treating minor pains, but it cannot treat swelling.

Ibuprofen for muscle pain works in the reduction of pain and inflammation and is more efficient than:

  • Muscle strains
  • Post-exercise soreness
  • Sports injuries

When people want painkillers, they will call Motrin and Tylenol for headaches and sore muscles because they are more efficient.

How Safe Are They?

Ibuprofen risks:

  • Upset stomach
  • Ulcers when over-used
  • May raise blood pressure
  • Risk of chronic kidney issues in the long-term use

Acetaminophen risks:

  • The chance of liver damage when you take a higher dose than the recommended dose
  • Do not combine with alcohol
  • Totals not to exceed 4,000mg/day

Never miss reading labels, and when unsure, consult your physician.
