Advil and Tylenol are both medications used to relieve pain and reduce fevers. Advil also has anti-inflammation properties so it is used for treating arthritis or join pain. There are differences in the mechanism of action and side effects of the two drugs.
The active ingredient in Advil is Ibuprofen, whereas in Tylenol it is Acetaminophen. Taking Advil is not recommended if a child is vomiting, not eating much or otherwise on an empty stomach, or is dehydrated. It may damage the stomach lining or kidneys. On the other hand, too much tylenol can cause damage to the liver.

Active ingredient in Tylenol vs Advil
The active ingredient in Advil is ibuprofen, which is a non-steroidal anti-inflammatory drug. On the other hand, the active ingredient in Tylenol is acetaminophen (also known as paracetamol), an analgesic and an antipyretic agent.
Mechanism of action
Advil acts by inhibiting cyclooxygenases (COX-1 and COX-2), and thus prostaglandins, which are produced by the body in response to injury and inflammation. Acetaminophen (the active ingredient of Tylenol) is a weak inhibitor of the synthesis of prostaglandins.
The mechanism of action of Tylenol is different from that of Advil because Tylenol is considered to be a weaker inhibitor of COX-1 and COX-2. The possibility of it inhibiting a third variant COX-3 is being investigated by scientists.
Tylenol and advil are both metabolized in the liver, broken down into non-toxic products and then excreted by the kidneys through urine.
The adult dose for Advil is around 200mg to 800mg per dose, a maximum of four times a day. In children the dose is 5-10 mg/Kg. In case of an overdose, consult your physician.
For adults, the dose for Tylenol is 325-650 mg every 4 to 6 hours. In children, this dose is less - about 7mg per pound of body weight. Taking an overdose of Tylenol can cause side effects and should be avoided.
The common side effects of Advil at high doses include nausea, gastrointestinal bleeding, diarrhea, constipation, headache, dizziness, salt and fluid retention and hypertension. Other rare side effects include esophageal ulcers, heart failure, renal impairment, and confusion.
Side effects due to overdose of acetaminophen (Tylenol) include risk of stomach bleeding, kidney or liver damage, stomach pain, or severe allergic reaction like swelling, dizziness, breathing and other reactions.
Tylenol has been recalled twice. The 1982 Chicago Tylenol murders caused a huge scare in the United States and caused the company to recall 31 million bottles of tablets. This was an immense blow to the brand but it recovered and was gradually rebuilt over several years.
There was another Tylenol recall in January 2010. On January 15, 2010, 20 months after first receiving consumer complaints, Johnson & Johnson announced a voluntary recall of several hundred batches of popular medicines, including Benadryl, Motrin, Rolaids, Simply Sleep, St. Joseph Aspirin and Tylenol. The recall was due to complaints of a musty smell which is suspected to be due to contamination of the packaging with the chemical 2,4,6-tribromoanisole.
Advil has never been the subject of a recall so it certainly has a better track record than Tylenol in this respect.
Advil is available in the form of tablets, chewable tablets, capsules, suspensions and oral drops. Tylenol is available in liquid suspension, chewable tablets, gelcaps, geltabs, and suppositories.
Advil taken with other drugs such as aminoglycosides or warfarin may cause side effects and should be avoided. Drugs such as carbamazepine, isoniazid, rifampin, and cholestyramine reduce the effect of Tylenol.
