How long do you need to wait before Tylenol starts working?

Every time we have a fever or a headache, the first thing that comes to our mind is definitely Tylenol. It is a common over-the-counter medicine that everyone can buy directly from any pharmacy or grocery store without a prescription. However, it is important to know how to use it properly to prevent undesirable side effects. That being said, let’s find out what’s the recommended dose of Tylenol, how long it takes before kicking in, and how long it lasts.

What is Tylenol used for?

Tylenol is the most famous pain reliever/fever reducer brand in the world. The latter mainly contains the amount of Acetaminophen used to ease common cold, fever, and the following minor pains:

  • Headache
  • Muscle ache
  • Toothache

Normally, Tylenol comes as solid tablets (350 and 500 mg), but other forms are also available, such as capsule, oral gel, chewable tablets, etc.

How can Tylenol relieve pain and fever?

Acetaminophen in Tylenol is responsible for increasing the pain tolerance level. As a result, it can temporarily relieve pain and help your body go through all discomforts. Besides, it also reduces fever by commanding the heat-regulating center of your brain to lower the temperature of the body.

What is the safe dose of Tylenol and how to use it?

Although this medication is available almost anywhere you go, the possible side effects can be unpleasant and even in some cases dangerous (especially in case of misusing). Overdosing may indeed cause significant health problems, particularly in the liver, if you overdose too often. Therefore, it is important to respect the prescribed dosage.

Below is the guide about the right dosage of Tylenol:

  • For adults, you can take 1-2 tablets of 325 mg or 500 mg every 4 to 6 hours, while the 650 mg tablets should be taken every 8 hours.
  • Keep in mind that the safe dose is around 3,000 – 4,000 mg per day.
  • For Children under age 12, it is advised to consult a doctor or pharmacist before use.

Important cautions:

  • Tylenol is not recommended for people suffering from chronic liver disease.
  • Do not use it if you are taking blood-thinning drugs.
  • You must go to the hospital immediately for examination if you notice the following symptoms:
    – Signs of allergic reactions, for example, itchy skin, red rash, blisters, etc.
    – Loss of appetite
    – Stomachache
    – Nausea and vomiting
    – Abnormal color in urine and stool
    – Abnormal yellow eye (jaundice)
  • Pregnant and nursing mothers should consult the specialist before use.
  • Avoid consuming alcohol at least 24 hours after taking Tylenol.

How long does it take for Tylenol to start working?

Tylenol generally helps you feel better in 30 minutes. However, the time will vary depending on the individual and the form of the medication you take. Here is an estimated length of time:

  • Solid Tablets: 30-45 minutes
    You will need to wait until the medication has totally been absorbed through your digestive system for solid tablets. In general, your illnesses should be relieved within 30-45 minutes, but on a full stomach it may take up to 1 hour. Thus, it is advised to take Tylenol before a meal for faster results.
  • Liquid filled capsule: 20 minutes
    The latter usually works faster than solid pills, since the liquid Acetaminophen in the capsule can be absorbed easily.
  • Intravenous acetaminophen: 5-10 minutes
    Injection of the medication into a vein can provide the most effective and the fastest effects, but it must be performed by a doctor only.

How long does Tylenol last in the system?

After taking a Tylenol 500 mg tablet, the amount of acetaminophen could stay in your bloodstream for 4 to 6 hours, or even 8 hours in some cases. This is the reason why you should wait at least 4 hours before the second dose to prevent taking too much of a substance.
