Is it safe to take aspirin and Tylenol together

How Aspirin and Tylenol (Paracetamol/Acetaminophen) work (mode of action)?

The Aspirin (also known as acetylsalisylic acid) is an antipyretic, analgesic and anti inflammatory agent widely used in the treatment of mild to moderate pain. The drug also has anti platelet aggregation properties, therefore used for management of arterial and venous thrombosis. Aspirin also appears to produce analgesia (peripheral and CNS effect) and antipyresis (via hypothalamus).

The mode of action of Aspirin is as follows:

 Aspirin belongs to the class of molecules known as non steroidal anti inflammatory drugs (NSAIDs).

  • This class (NSAIDs) of molecules act through inhibition of synthesis and release of hormones involved in pain and inflammation i.e. prostaglandins.
  • Similarly, Aspirin inhibits the prostaglandin synthesis and release through a direct inhibition of enzyme involved i.e.
  • Besides this, Aspirin also reduces platelet aggregation and therefore used as an antiplatelet drug.
  • The antipyretic and analgesic effects of Aspirin are mainly due to its action on hypothalamus.

Tylenol is the brand name of the drug acetaminophen also known as paracetamol. The drug possesses analgesic and antipyretic properties. The name Tylenol is basically derived from chemical name of the active compound of the drug (parasitamol) i.e. N-aceTYL-para-aminophENOL (APAP).  Tylenol is used to relieve pain, fever and symptoms of allergies, cough, cold, headache, and influenza.

The mode of action of Tylenol (Acetaminophen) is as follows:

  • The drug Acetaminophen is supposed to act directly on central nervous system (CNS).
  • Within the CNS, Tylenol inhibits prostaglandin (PG) synthesis through inhibition of cyclooxygenase (COX-1, COX-2, and COX-3) enzymes. This results in significant increment in pain threshold than the usual one.
  • However, Tylenol does not inhibit cyclooxygenase in peripheral brain tissues and therefore, unable to demonstrate peripheral anti-inflammatory affects.
