How does acetaminophen work in the body?
Acetaminophen works by inhibiting the production of prostaglandins in the brain. Prostaglandins are chemicals that promote inflammation, pain, and fever. By blocking their production, acetaminophen effectively reduces pain and fever. Unlike NSAIDs, acetaminophen does not reduce inflammation in the body, which makes it a suitable option for individuals who need pain relief without the anti-inflammatory effects. Its mechanism of action is primarily central, affecting the brain rather than peripheral tissues.
In what forms is acetaminophen available?
Acetaminophen is available in a variety of dosage forms to accommodate different patient preferences and needs. Common forms include oral tablets, chewable tablets, capsules, liquid suspensions, and rectal suppositories. Each form is designed to provide effective pain relief and fever reduction, with dosages varying based on the form and patient age. The versatility of acetaminophen's dosage forms makes it a convenient choice for both adults and children.
What are the most common side effects of acetaminophen?
While acetaminophen is generally well-tolerated, some individuals may experience common side effects. These can include nausea, vomiting, constipation, and mild abdominal pain.

Staying within the recommended dosage can help minimize the risk of side effects.
What are the serious or severe side effects of acetaminophen?
Serious side effects of acetaminophen are rare but can occur, especially with overdose or prolonged use. These may include liver damage, severe allergic reactions, and skin rashes.
