How Long Does Excedrin Stay In Your System

Excedrin is a pain reliever that primarily contains acetaminophen, aspirin, and other active components. Aspirin and acetaminophen help relieve pain by stopping your body from making chemicals that cause pain. Caffeine, included in several products, enhances the effects of aspirin and acetaminophen. It is used to ease mild aches and pains caused by headaches, colds, arthritis, muscular aches, toothaches, and premenstrual and menstrual cramps.

Acetaminophen, an analgesic and antipyretic, is the principal active ingredient in this medication. It isn’t an NSAID. In other words, it isn’t an anti-inflammatory medication. It has no effect on edema or inflammation. It works by inhibiting the enzyme cyclooxygenase (COX). These help make prostaglandins, which are molecules that send signals and are involved in pain and inflammation. As a result, acetaminophen would be similar to aspirin, ibuprofen, and other nonsteroidal anti-inflammatory medicines (NSAIDs).


How Long Does Excedrin Stay In Your System?

The length of effects of different drugs vary greatly. The same is true for how long a drug remains in the body’s systems after its effects have worn off. Some medications will stay in your system for days, while others will stay in your system for months. The length of time Excedrin remains in your system is determined by a number of factors, including:

  • Excedrin type. The length of time an Excedrin stays in your system is determined by various factors, including the type of Excedrin taken. Excedrin has been a headache relief industry leader for almost 50 years, and the Excedrin product line incorporates a variety of substances. Excedrin Migraine, for example, comprises acetaminophen, aspirin, and therapeutically active caffeine, but Excedrin PM is a nonprescription medicine that contains three ingredients: acetaminophen, aspirin, and diphenhydramine. Some medications are digested more quickly than others, and some take days to be completely cleared from the body.
  • Amount of Drug. The amount of Excedrin in your body is another aspect that influences how long it stays in your system. For example, short-term drug usage and lower doses may be noticeable for a short period of time. Heavy use, on the other hand, can result in prolonged detection times.
  • Half-Life of a drug. The half-lives of the ingredients in Excedrin vary. Diphenhydramine, for example, is eliminated unchanged in the urine and has a half-life of 3.4-9.2 hours, whereas caffeine has a half-life of roughly 5 hours. After 5 hours, someone who drinks 40 milligrams (mg) of caffeine will have 20 mg remained in their system.
  • Body Mass. This also influences how long Excedrin remains detectable in the body. Drug detection durations can be extended in people with larger body mass because some drugs accumulate in fatty regions.
  • Metabolic Rate. Drug detection times can also be affected by a person’s metabolic rate, which varies from one person to the next. Age and certain medical disorders might have an impact on metabolic rate. In general, the shorter the period Excedrin may be recognized in the body, the higher the metabolic rate.


Excedrin should not be given to a kid or teenager who has a fever, flu symptoms, or chicken pox. Aspirin can cause Reye’s syndrome, a potentially lethal illness in children.

Take no more Excedrin than is suggested. An acetaminophen overdose can harm your liver or even kill you. If you develop nausea, upper stomach pain, itching, loss of appetite, dark urine, clay-colored stools, or jaundice, contact your doctor right once (yellowing of your skin or eyes).

Aspirin can result in deadly stomach or intestinal hemorrhage. If you have symptoms like bloody or tarry stools, coughing up blood, or vomit that looks like coffee grounds, call your doctor right once.

Acetaminophen can cause serious skin reactions in rare circumstances. If you get skin redness or a rash that spreads and causes blistering and peeling, stop taking Excedrin and contact your doctor right once.

Excedrin usage

Excedrin should be taken exactly as indicated on the label or as suggested by your doctor. Take no more of this drug than is prescribed. An acetaminophen overdose can harm your liver or even kill you.

If Excedrin upsets your stomach, take it with food or milk.

If your symptoms do not improve after 7 days of treatment, or if you have a fever that lasts more than 3 days, or any swelling or pain that lasts more than 10 days, contact your doctor.

This medicine may provide unexpected findings when specific lab tests for glucose (sugar) in the urine are performed. Inform any doctor who treats you that you take Excedrin.

If you need surgery, inform the surgeon that you are taking Excedrin. You may need to discontinue the medication for a brief period of time.

Excedrin should be stored at room temperature, free from moisture and heat.


Acetaminophen and aspirin are the most prevalent active ingredients in most Excedrin products. Acetaminophen is rapidly absorbed from the GI tract, with peak plasma levels occurring in most cases within 2 hours and almost always within 4 hours. Acetaminophen has a half-life in the blood of 1.25 to 3 hours for most persons. Within 24 hours, all of the medication will have passed via the urine. It should be noted that this may take longer in people with impaired liver function.

It has been found that aspirin concentrations in blood peak roughly 20 minutes after oral administration in healthy individuals, while aspirin absorption and bioavailability in AMI may be quite different. However, because platelets cannot produce new COX, the effects of aspirin remain for the platelet’s whole life (ten days). It takes 10 days for the effects of aspirin from Excedrin products to wear off once a person stops taking it.
