How should I use Tylenol?
Use Tylenol exactly as directed on the label, or as prescribed by your doctor. Do not use in larger or smaller amounts or for longer than recommended.
Do not take more Tylenol than is recommended. An overdose can damage your liver or cause death.
Measure the liquid form of Tylenol with a special dose-measuring spoon or cup, not a regular table spoon. If you do not have a dose-measuring device, ask your pharmacist for one. You may need to shake the liquid before each use. Follow the directions on the medicine label.
If you are treating a child, use a pediatric form of Tylenol. Use only the special dose-measuring dropper or oral syringe that comes with the specific pediatric form you are using. Carefully follow the dosing directions on the medicine label. Tylenol made for infants is available in two different dose concentrations, and each concentration comes with its own medicine dropper or oral syringe. These dosing devices are not equal between the different concentrations. Using the wrong device may cause you to give your child an overdose of acetaminophen. Never mix and match dosing devices between infant formulations of acetaminophen. Shake the liquid before each use. Follow the directions on the medicine label.
The chewable tablet must be chewed thoroughly before you swallow it.
Stop using Tylenol and call your doctor if:
you still have a fever after 3 days of use;
you still have pain after 7 days of use (or 5 days if treating a child);
you have a skin rash, ongoing headache, or any redness or swelling; or
if your symptoms get worse, or if you have any new symptoms.
Tylenol can cause unusual results with certain lab tests for glucose (sugar) in the urine. Tell any doctor who treats you that you are using actaminophen.
Store Tylenol at room temperature away from heat and moisture.
What happens if I miss a dose?
Since Tylenol is taken as needed, you may not be on a dosing schedule. If you are taking the medication regularly, take the missed dose as soon as you remember. Skip the missed dose if it is almost time for your next scheduled dose. Do not take extra medicine to make up the missed dose.

The first signs of an acetaminophen overdose include loss of appetite, nausea, vomiting, stomach pain, sweating, and confusion or weakness. Later symptoms may include pain in your upper stomach, dark urine, and yellowing of your skin or the whites of your eyes.
