Updated on January 24, 2014

What is Tylenol?

Tynelol is simply a brand name. It is chemical name is something else, a long name, difficult to remember - N-Acetyl-para-aminophenol. Tylenol is owned by Johnson and Johnson healthcare group. this product is also named as Acetaminophen and Paracetamol, the name most commonly in use in the world.

As we all know, the medicine is available without a prescription from a physician. This practice was started as far back as in 1960.

This is a white, odorless powder with a slight bitter taste.

What is the action of this chemical?

Remember, Acetaminophen is having analgesic and antipyretic actions, but certainly very minimal anti-inflammatory properties.

What does that mean?

It means that Tylenol can relieve our pain and reduce fever only. It cannot subside tissue changes that occur due any disease processes.

Again, remember, its action lasts for a certain period only. That means it is temporary. We need to take the medication again after a specific period.

What type pain it can reduce?

It relieves us from mild degree of pain, particularly due to common cold, toothache, minor injuries, muscle pain, backache, pain due to arthritis in joints. With regard to arthritis, we should remember that pain occurs due to the inflammation which is not controlled by this chemical.

For the above conditions, Tylenol is effective for all age groups including infants.

How does it reduces fever?

It blocks some chemicals which are released due to any disease process, acting on the brain's fever control center, which in the hypothalamus section in the brain.

We need to remember that the chemical does not do anything to arrest the disease process. It merely control fever.

How does it reduce pain?

It is interesting although this action has been well established for a long time, the exact place it acts upon and its exact mechanism of action is yet to find out! However, it is believed to act on the brain, more specifically on the Central Nervous System. .



For What It Is Used For

it is recommended for the following conditions;

How long its action lasts?

Once we ingest the medication in whatever form, it achieves its maximum level in blood within 30 minutes. After that its blood level slowly goes down over a period of 8 hours. That means its action lasts only 8 hours. By then, if the disease process is not over, fever and pain reappear.

Does food block its absorption to blood?

You read earlier that the chemical will be in the blood within 30 minutes after taking it. Generally, food does not block its absorption into blood, although it may delay.

Does the chemical pass in to breast milk?

Yes, but if the mother took the recommended levels, its availability in breast milk does not pose any risk to the nursing baby.
