Tylenol uses:

This medicine is used to treat and minimize fever with mild to moderate pain (from headaches, menstrual cycles, toothaches, backaches, osteoarthritis, or cold/flu aches and pains).

How to use

  • As directed, take this Tylenol 500 by mouth. On the product box, follow all instructions. Ask your doctor or pharmacist if you have any questions.
  • There are several acetaminophen labels and formulations available. As the amount of acetaminophen can vary between products, read the dosing instructions carefully for each product. Do not take more than the prescribed amount of acetaminophen.
  • Be sure to use a medication that is intended for children if you are giving acetaminophen to a child. To find the correct dosage on the food box, use your child's weight. If you don't know the weight of your child, you can make use of their age.
  • Shake the drug well before each dose in case of suspension. Before use, such liquids do not need to be shaken. On the product box, follow all instructions. To make sure you have the right dosage, measure the liquid medicine with the dose-measuring spoon/dropper/syringe given. Do not use a spoon for household use.
  • Chew or allow to dissolve on the tongue for quickly-dissolving tablets, then swallow with or without water. For chewable pills, before swallowing, chew thoroughly.
  • Do not smash the extended-release tablets or chew them. In doing so, all of the drugs will be released at once, raising the risk of side effects.
  • Dissolve the dosage into the recommended amount of water for effervescent pills, then drink.
  • As the first symptoms of pain occur, pain killers perform better if they are used. The drug can not function as well if you wait until the symptoms have worsened.
  • Do not use this fever drug for more than 3 days unless advised to do so by your doctor. Do not take this medication for more than 10 days (5 days in children) for pain in adults, unless instructed by your doctor. Consult the doctor promptly if the child has a sore throat (especially with a high fever, headache, or nausea/vomiting).
  • If the condition continues or worsens, or if you experience new symptoms, tell your doctor.

Never share the medication with anyone having the same health problems. Before taking it please get a consultation with your doctor. The stomach and intestinal ulcers that NSAIDs such as aspirin, ibuprofen, and naproxen can cause are not caused by acetaminophen. Acetaminophen, however, does not decrease swelling/inflammation as NSAIDs do. For more information and to see which treatment may be right for you, contact your doctor.

Missed Dose:

You may not be on a dosing schedule since acetaminophen is used when needed. If it is almost time for your next dose, skip any skipped doses. Do not use two doses simultaneously.


Seek medical attention for emergencies. Acetaminophen overdoses can damage your liver or lead to death. Loss of appetite, nausea, vomiting, sweating, or fatigue is early symptoms of acetaminophen overdose. Upper stomach pain, dark urine, and yellowing of the skin or eyes can be later signs.


Store it away from light and moisture at room temperature. Do not store your things in the bathroom. Hold kids and pets away from all drugs. Unless or until told to do so, never flush this in the toilets or dump them into the drainage system. When it is expired or no longer needed, properly discard this product.

Frequently Asked Questions:

This medicine is used to treat and minimize fever with mild to moderate pain (from headaches, menstrual cycles, backaches, toothaches, osteoarthritis, or cold/flu aches and pains).
On drugstore shelves, Tylenol, Advil, and Aleve are popular pain relievers. While all three drugs can help relieve the pain of a child, the active ingredient in each medication is different. There is acetaminophen in Tylenol; there is ibuprofen in Advil and Motrin, and there is naproxen in Aleve.
The recommended daily dosage is 4,000 milligrams for a healthy adult who weighs at least 150 pounds (mg). However, taking the full daily dose for long periods can seriously affect the liver in certain people. It's best to take the lowest necessary dose and stick closer to your daily dose of 3,000 mg per day.
If you are allergic to it, or if you have serious liver disease, you should not take acetaminophen. If you have ever had alcoholic liver disease (cirrhosis) or if you consume more than 3 alcoholic drinks a day, do not take acetaminophen without a doctor's recommendation.
