Tylenol<\/span><\/a> is an over-the-counter (OTC) pain reliever that contains the active ingredient acetaminophen. It can be used in adults and children to relieve symptoms of pain (such as those from a <\/span>sore throat<\/span><\/a> or headache) and reduce a <\/span>fever<\/span><\/a>. Although many people think that Tylenol and Motrin (ibuprofen) are the same, they are not. Motrin is a nonsteroidal anti-inflammatory drug (<\/span>NSAID<\/span><\/a>). NSAIDs help with pain, fever, and inflammation. Tylenol is known as an analgesic\u2014not an NSAID\u2014and does not relieve inflammation.\u00a0<\/span><\/p>\n

If you or someone you care for isn\u2019t feeling well, you may wonder how long it takes for Tylenol to start working. It typically takes about 45 minutes for Tylenol tablets to start working, although other formulations may begin to work more quickly. Continue reading to learn more about how fast different formulations of Tylenol work to relieve your symptoms.\u00a0<\/span><\/p>\n\t\t

How long does it take Tylenol to work?<\/span><\/h2>\n

The time it takes for Tylenol (<\/span>acetaminophen<\/span><\/a>) to work depends on the form of the medication you are taking (for example, a liquid or pill formulation) and <\/span>other factors<\/span><\/a> that can influence its effectiveness.\u00a0<\/span><\/p>\n

Effervescent forms<\/span><\/h3>\n

A study in the <\/span>Journal of Clinical Pharmacology<\/span><\/i><\/a> found that effervescent forms of acetaminophen began to take effect in approximately 20 minutes, with noticeable pain relief occurring around 45 minutes. The tablet form, in comparison, started working in about 45 minutes and provided meaningful pain relief by the 60-minute mark. Four hours after taking the medication, however, pain relief was better in patients who took the tablet form.\u00a0<\/span><\/p>\n

Although there are no effervescent forms of Tylenol as a single-ingredient product in the United States, the active ingredient in Tylenol, acetaminophen, can be found in certain effervescent products, such as <\/span>Alka-Seltzer Plus Severe Cold and Flu<\/span><\/a>, which contains acetaminophen along with other medications that help alleviate cough and relieve stuffy or runny nose symptoms.\u00a0<\/span><\/p>\n

When taking a combination product like this, ensure that each ingredient is safe for you to consume. Depending on your symptoms, a single-ingredient product may be better to minimize side effects and drug interactions. The closest formulation to effervescent Tylenol tablets available in the United States is the Tylenol dissolve packs.<\/span><\/p>\n

Immediate-release forms<\/span><\/h3>\n

An immediate-release Tylenol product will reach its highest levels in the body within 30\u201360 minutes. Liquids and dissolve packs may <\/span>work faster<\/span><\/a> than other forms\u2014and taking Tylenol on an empty stomach may help it work faster, too.<\/span><\/p>\n

Extended-release forms<\/span><\/h3>\n

Extended-release formulations of Tylenol, such as extended-release tablets, reach their highest levels in the body within one to two hours. If you take extended-release Tylenol with food, it may take slightly longer for the body to absorb the medicine.\u00a0<\/span><\/p>\n

Acetaminophen suppositories<\/span><\/h3>\n

Acetaminophen suppositories (<\/span>rectally administered acetaminophen<\/span><\/a>) vary in how fast they start working. The suppository takes about three hours to reach its maximum effect, which is considerably slower than when acetaminophen is taken orally, such as in liquid form. However, there are times when a rectal formulation may be needed, such as when a child is vomiting and cannot keep anything down.\u00a0<\/span><\/p>\n

Intravenous acetaminophen<\/span><\/h3>\n

Intravenous acetaminophen<\/span><\/a>, which is a prescription form of acetaminophen given by a medical professional in a healthcare setting, is infused over 15 minutes. It begins to work immediately, reaching its peak levels in the body by the end of the 15-minute infusion.\u00a0<\/span><\/p>\n

Different types of Tylenol<\/span><\/h2>\n

There are various types and formulations of Tylenol, including tablets, chewable tablets, liquids, and others, available over the counter. Some OTC medications contain acetaminophen, the ingredient in Tylenol, in combination with other medicines (e.g., certain <\/span>migraine<\/span><\/a> medications and combination <\/span>cough and cold<\/span><\/a> products). And, some medications that contain acetaminophen are prescription-only (e.g., acetaminophen that is injected by a healthcare provider and certain <\/span>opioid combination pain medications<\/span><\/a> used for severe pain).\u00a0<\/span><\/p>\n

How long does Tylenol last?<\/span><\/h2>\n

In addition to knowing how fast Tylenol takes to work, you may wonder about the duration of action or how long each dose of Tylenol will last. A medication\u2019s <\/span>half-life<\/span><\/a> is the time it takes for your body to clear about half of a dose of medication. The half-life of Tylenol (oral formulations) can range from one to three hours. It takes approximately five half-lives for the medication to be almost completely eliminated from the body, so a dose of Tylenol may remain in the body for between five and 15 hours, even though pain relief typically lasts four to six hours. Most forms of Tylenol are dosed every four to six hours as needed so that you can take another dose before the previous dose wears off.\u00a0<\/span><\/p>\n\n\n\n\n\n\n\n\n\n\n\n\n
