Tylenol (acetaminophen) is a leading over-the-counter analgesic and antipyretic medication with a well-established safety profile when used as directed. As a non-aspirin pain reliever, it provides effective temporary relief from minor aches and pains associated with headaches, muscle aches, arthritis, backaches, toothaches, the common cold, and menstrual cramps, while also reducing fever. Its mechanism of action, while not fully understood, is believed to involve elevating the pain threshold and acting on the hypothalamic heat-regulating center. This product card provides comprehensive, expert-level information for informed and responsible use.
Features
- Active Ingredient: Acetaminophen (500 mg per caplet/tablet in regular strength formulations)
- Drug Class: Analgesic (pain reliever) and Antipyretic (fever reducer)
- Formulation: Available in caplets, tablets, gelcaps, liquid gels, and liquid suspensions
- Non-prescription (Over-the-Counter) status for most formulations
- Non-aspirin and non-steroidal anti-inflammatory drug (NSAID)
- Generally considered gentler on the stomach than NSAIDs like ibuprofen or naproxen sodium
Benefits
- Provides fast-acting, effective temporary relief from minor aches and pains.
- Effectively reduces fever associated with colds, flu, and immunizations.
- Offers a pain relief option for individuals who cannot take NSAIDs due to stomach sensitivity, ulcers, or certain bleeding disorders.
- Does not interfere with blood clotting, unlike aspirin and other NSAIDs.
- Suitable for use in many patient populations, including children (with appropriate pediatric formulations and dosing) and pregnant women (after consulting a healthcare provider).
- Allows for management of discomfort without the anti-inflammatory effects, which may be preferable in certain clinical scenarios.
Common use
Tylenol (acetaminophen) is commonly used for the temporary relief of minor to moderate pain. This includes headaches, including tension-type headaches; musculoskeletal pain such as backaches, muscle aches, and minor pain of arthritis; toothaches; and dysmenorrhea (menstrual cramps). It is also widely indicated for the reduction of fever. It is important to note that while it is effective for pain and fever, it does not possess significant anti-inflammatory properties and is therefore not indicated for the reduction of inflammation, such as that seen in rheumatic conditions.
Dosage and direction
Always read and follow the product label. Dosing may vary by formulation (e.g., regular strength, extra strength) and patient age. The following is for general educational purposes for adults and children 12 years and older using regular strength (500 mg) caplets/tablets.
- Adults and Children 12 years and over: Take 1-2 caplets every 4 to 6 hours as needed for pain or fever.
- Do not take more than 8 caplets in 24 hours.
- Children under 12 years: Use only under the direction and dosing guidance of a doctor. Use only products labeled for pediatric use.
- Direction: Swallow caplet/tablet whole with a full glass of water. May be taken with or without food. If stomach upset occurs, take with food.
- Do not use for more than 10 days for pain or 3 days for fever unless directed by a doctor.
Precautions
- Liver Warning: This product contains acetaminophen. Severe liver damage may occur if you take:
- more than 4,000 mg of acetaminophen in 24 hours.
- with other drugs containing acetaminophen.
- 3 or more alcoholic drinks every day while using this product.
- Allergy Alert: Acetaminophen may cause severe skin reactions. Symptoms may include: skin reddening, blisters, rash. If a skin reaction occurs, stop use and seek medical help right away.
- Do not use if you are allergic to acetaminophen or any other ingredient in this product.
- Ask a doctor before use if you have liver disease.
- Ask a doctor or pharmacist before use if you are taking the blood thinner warfarin.
- Stop use and ask a doctor if pain gets worse or lasts more than 10 days, fever gets worse or lasts more than 3 days, new symptoms occur, or redness or swelling is present.
Contraindications
Tylenol is contraindicated in patients with:
- Known severe hypersensitivity to acetaminophen or any component of the formulation.
- Severe hepatic impairment or severe active liver disease.
Possible side effect
When taken at recommended doses, acetaminophen is generally well-tolerated. Rare but serious side effects require immediate medical attention.
- Serious Side Effects (seek medical help immediately): Signs of an allergic reaction (hives; difficulty breathing; swelling of your face, lips, tongue, or throat); signs of skin reaction (fever, sore throat, burning in your eyes, skin pain, red or purple skin rash that spreads and causes blistering and peeling). Signs of liver problems (nausea, upper stomach pain, itching, loss of appetite, dark urine, clay-colored stools, jaundice (yellowing of the skin or eyes)).
- Less Serious Side Effects (less likely at correct doses): Nausea, stomach pain, headache.
Drug interaction
Acetaminophen can interact with other medications, potentially altering their effects or increasing the risk of adverse events.
- Warfarin (Coumadin, Jantoven): Long-term use of acetaminophen may increase the anti-clotting effect of warfarin, slightly increasing the risk of bleeding. This risk is greater with daily use of acetaminophen. Occasional use is less likely to cause an interaction, but you should still inform your doctor.
- Other Acetaminophen-Containing Products: Concurrent use can lead to accidental acetaminophen overdose and acute liver failure. Check labels of all other OTC and prescription medications (e.g., cough and cold products, prescription pain relievers like Vicodin, Percocet) for acetaminophen.
- Isoniazid: A medication used to treat tuberculosis. Concomitant use may increase the risk of liver toxicity.
- Alcohol: Chronic, heavy alcohol use induces liver enzymes and can potentiate the hepatotoxicity of acetaminophen. Consumption of three or more alcoholic drinks per day is contraindicated while taking this product.
- Certain Anticonvulsants (e.g., phenytoin, carbamazepine, barbiturates): These drugs can also increase the metabolism of acetaminophen to its toxic metabolite, potentially increasing liver risk.
Missed dose
This medication is typically taken on an as-needed basis for pain or fever. It is not intended for scheduled dosing. Therefore, the concept of a “missed dose” does not generally apply. If a healthcare provider has specifically instructed you to take acetaminophen on a regular schedule, take the missed dose as soon as you remember. If it is almost time for your next scheduled dose, skip the missed dose and take your next dose at the regular time. Do not take two doses at one time to make up for a missed dose.
Overdose
Acetaminophen overdose can be fatal and requires immediate medical attention, even if you do not initially feel sick. Early symptoms of overdose may be non-specific (nausea, vomiting, loss of appetite, sweating, general malaise) and can often be mistaken for the flu. These initial symptoms may subside for 24-48 hours, after which signs of liver damage (pain in the upper right abdomen, jaundice, coagulopathy) can appear.
- In case of overdose, call your local poison control center at 1-800-222-1222 or seek emergency medical attention immediately.
- Quick medical intervention is critical. The antidote for acetaminophen overdose, N-acetylcysteine (NAC), is most effective when administered within 8-10 hours of ingestion but can still be beneficial if given later.
- Do not wait for symptoms to appear. If you suspect an overdose, seek help immediately.
Storage
- Store at room temperature (20-25°C or 68-77°F) away from light, heat, and moisture.
- Do not store in the bathroom. High humidity can degrade the medication.
- Keep the bottle tightly closed and out of reach of children and pets to prevent accidental ingestion.
- Safely discard any expired medication or medication that is no longer needed.
