Paracetamol: Uses, Dosage, Side Effects and More

Introduction: What is Paracetamol?

Paracetamol, also known as acetaminophen, is a widely used medication for pain relief and fever reduction. It is one of the most common over-the-counter drugs available globally and is often recommended for various conditions, including headaches, muscle aches, arthritis, backaches, toothaches, colds, and fevers. Paracetamol is favored for its effectiveness and safety profile when used as directed.

Uses of Paracetamol

Paracetamol is approved for several medical uses, including:

1. Pain Relief: It is effective for mild to moderate pain, such as headaches, menstrual cramps, toothaches, and muscle aches.
2. Fever Reduction: Paracetamol is commonly used to lower fever in both adults and children.
3. Post-Surgical Pain: It is often prescribed after surgical procedures to manage pain.
4. Chronic Pain Management: In some cases, it is used as part of a treatment plan for chronic pain conditions.

How It Works

Paracetamol works primarily in the brain. It inhibits the production of certain chemicals called prostaglandins, which are responsible for causing pain and inflammation. By reducing these chemicals, paracetamol helps to alleviate pain and lower fever. Unlike nonsteroidal anti-inflammatory drugs (NSAIDs), paracetamol does not significantly reduce inflammation, making it a suitable option for individuals who cannot tolerate NSAIDs.

Dosage and Administration

The standard dosages for paracetamol are as follows:

• Adults: The typical dose is 500 mg to 1000 mg every 4 to 6 hours, not exceeding 4000 mg in 24 hours.
• Children: The dosage is based on the child's weight, usually 10-15 mg per kg of body weight every 4 to 6 hours, not exceeding 5 doses in 24 hours.

Paracetamol is available in various forms, including:

• Tablets: Commonly used for adults.
• Liquid Suspension: Often used for children.
• Suppositories: Useful for those who cannot take oral medications.
• Injectable Form: Used in hospitals for severe pain management.
