WARNING

Acetaminophen (paracetamol) is generally safe when taken as directed, but there are several risks, especially with high doses or long-term use:

• Liver Damage: The most serious risk, which can occur with overdose or chronic use, particularly in those with liver disease or who consume alcohol.
• Allergic Reactions: Rare but severe reactions like skin rashes (Stevens-Johnson syndrome) or anaphylaxis.
• Kidney Damage: Long-term use can increase the risk of kidney disease, especially in those with pre-existing conditions.
• Blood Disorders: Rare cases of low blood cell counts (thrombocytopenia, agranulocytosis).
• Cardiovascular Risks: Possible increased risk of high blood pressure and heart problems with long-term use.
• Gastrointestinal Issues: Less common than NSAIDs but can cause nausea, vomiting, or stomach pain.
• Drug Interactions: Can interact with alcohol and certain medications, increasing the risk of liver damage or other complications.
• Risks in Specific Populations: Extra caution is needed for pregnant or breastfeeding women, children, older adults, and those with pre-existing conditions.

Always follow dosing instructions, avoid alcohol, and consult a healthcare provider if needed.

Why is this medication prescribed?

Acetaminophen is often prescribed for several reasons, primarily related to its ability to relieve pain and reduce fever. Here are some common reasons it might be prescribed:

• Pain Relief: It is used to relieve mild to moderate pain, such as headaches, muscle aches, arthritis, backaches, toothaches, or menstrual cramps.
