Tylenol, also known as acetaminophen, is a common over-the-counter pain reliever and fever reducer. The maximum recommended dose of Tylenol for adults is 4000 mg per day. Exceeding this dose can lead to liver damage.
Quick Answers
The quick answers to how much 500mg Tylenol you can take per day are:
- The maximum daily dose of Tylenol is 4000 mg.
- With 500mg Tylenol tablets, this equates to 8 tablets in 24 hours.
- It is not recommended to exceed 3000 mg per day for long-term use.
- Always read and follow dosing instructions on the Tylenol bottle.
- Consult your doctor if you need to take Tylenol regularly or in higher doses.
Dosing Guidelines
Tylenol comes in both over-the-counter and prescription strengths, with the most common over-the-counter forms being 325 mg and 500 mg tablets or capsules. Here are the dosing guidelines for Tylenol based on the strength:
| Tylenol Form | Single Dose | Maximum Daily Dose |
|---|---|---|
| 325 mg tablet or capsule | 650 mg (2 tablets) | 4000 mg (12 tablets) |
| 500 mg tablet or capsule | 1000 mg (2 tablets) | 4000 mg (8 tablets) |
As you can see from the table, the maximum recommended daily dose of 4000 mg equates to:
- 12 regular strength (325 mg) Tylenol tablets or capsules
- 8 extra strength (500 mg) Tylenol tablets or capsules
It is not recommended that you take more than the maximum daily dose. In fact, taking up to the maximum dose should only be done occasionally. For long-term or chronic pain, it is advisable to limit Tylenol use to less than 3000 mg per day.
Timing of Doses
In addition to not exceeding the maximum daily dose, it is also important to space out your doses of Tylenol evenly over the course of the day. Tylenol should be taken every 4-6 hours as needed. Here are some examples of appropriate dosing schedules:
- 2 extra strength (500mg) tablets every 6 hours
- 1 regular strength (325mg) tablet every 4 hours
- 1 extra strength (500mg) tablet every 4-6 hours
Avoid taking more than 2 extra strength or 4 regular strength tablets in any 4-6 hour time period. Also avoid double dosing to “catch up” if you miss a dose. Staggering the doses evenly helps maintain stable levels of the medication in your system.
Special Considerations
There are some special factors to consider when determining how much Tylenol is appropriate to take in a day:
- Age – Lower maximum doses apply for children. Children 6-11 years can take up to 2400 mg, 3-5 years up to 1600 mg, and under 3 up to 60 mg/kg per day.
- Alcohol use – Consuming 3 or more alcoholic drinks per day while taking Tylenol can increase the risk of liver damage. Total daily doses should be reduced to 2000 mg or less per day if drinking alcohol.
- Liver problems – Those with liver disease or impairment should take even less Tylenol than the maximum daily dose and be closely monitored by a doctor.
- Medications – Taking certain prescription medications can increase the toxicity of Tylenol to the liver. Check with your pharmacist about drug interactions.
Risks of Too Much Tylenol
Exceeding the recommended maximum daily dose of Tylenol can lead to severe health consequences. Taking too much Tylenol can result in:
- Liver toxicity – Tylenol overdose can irreversibly damage liver cells leading to liver failure.
- Kidney toxicity – Kidney function can be impaired with Tylenol overdose.
- Stomach bleeding – Taking above the daily limit raises the risk of gastrointestinal bleeding requiring hospitalization.
- Severe allergic reaction – Some people may experience severe allergic reactions to excessive doses of Tylenol resulting in breathing problems, rashes, or swelling.
- Death – Tylenol overdose can be fatal. Seek emergency medical attention immediately if you suspect Tylenol overdose.
To avoid these risks, be sure to carefully read and follow the dosing instructions provided with Tylenol products. Never exceed the maximum recommended daily dose.
Signs of Tylenol Overdose
Watch for these symptoms of possible Tylenol overdose and seek medical help immediately if they occur:
- Nausea, vomiting, or loss of appetite
- Stomach pain and discomfort

- Yellowing skin or eyes (jaundice)
- Unusual bleeding or bruising
- Confusion, anxiety, irritability

The signs of overdose can begin within 24 hours of taking too much Tylenol. Damage often occurs gradually over several days. Quick treatment can help prevent serious complications.
Avoiding Accidental Overdose
It’s important to take steps to avoid accidentally exceeding the recommended daily dose of Tylenol. Here are some tips:
- Carefully read all medication labels each time before use.
- Measure doses carefully using the provided dosing device.
- Don’t take multiple Tylenol products together that add up to too high a dose.
- Don’t take Tylenol with other medications containing acetaminophen.
- Keep track of timing between doses and total daily amount.
- Don’t drink alcohol while taking Tylenol.
- Get in the habit of writing down each dose you take.
- Ask your pharmacist or doctor if you are unsure about dosing instructions.
Use extra caution and always consult a doctor before giving Tylenol to children to avoid accidental overdose.
When to Call a Doctor
In addition to the overdose symptoms already covered, you should call your doctor in these situations while taking Tylenol:
- You need to take more than the maximum recommended dose
- You need to take Tylenol regularly for chronic pain
- You are already taking any other prescription or over-the-counter pain relievers or fever reducers
- You have a history of liver disease or drink 3 or more alcoholic beverages daily

Your doctor can help assess your specific situation and provide guidance on the appropriate dosing of Tylenol or recommend alternative pain relievers or treatments if needed.
Conclusion
The maximum daily dose of Tylenol (acetaminophen) is 4000 mg, which equates to 8 extra strength 500 mg tablets. However, it is recommended to take no more than 3000 mg per day for long-term use. Carefully follow dosing instructions on the Tylenol bottle and never exceed the maximum amounts. Space out doses evenly over the day every 4-6 hours. Watch for signs of overdose and call your doctor if higher doses are needed. Taking more Tylenol in a day than recommended can lead to severe liver damage and other dangerous health effects. When used responsibly at appropriate doses, Tylenol can be a safe and effective over-the-counter pain reliever and fever reducer.
