Brufen 400 mg for Fever: When and How to Use It

Introduction

Fever is one of the most common signs of infection, inflammation, or immune reaction. It makes you weak, tired, and uncomfortable. To fight these symptoms effectively, most doctors prescribe Brufen 400 mg, one of the most popular NSAIDs (Non-Steroidal Anti-Inflammatory Drugs) used to give immediate relief from fever and body aches.

This comprehensive manual will educate you on how Brufen 400 mg operates for fever, when and how to take it, proper dosage, side effects, precautions, and anything else you need to know to safely and effectively control fever.

What Is Brufen 400 mg?

Brufen 400 mg is a brand name product that contains 400 milligrams of ibuprofen. It belongs to the category of NSAIDs, which are a class of medications that assist:

• Reduce fever (antipyretic)

• Alleviate pain (analgesic)

• Control inflammation (anti-inflammatory)

Ibuprofen is usually suggested for quick relief from mild to moderate fever, particularly when it occurs with muscle pains, sore throat, or general sickness.

How Does Brufen 400 mg Work for Fever?

Brufen (ibuprofen) functions by preventing cyclooxygenase enzymes (COX-1 and COX-2), which are involved in producing prostaglandins — chemicals that cause fever, pain, and inflammation in the body.

By reducing prostaglandin production, Brufen helps:

• Lower body temperature

• Alleviate chills and sweating

• Relieve headaches and body aches that accompany fever

• Enhance comfort during recovery from viral or bacterial infections
